A good micro lab extruder factory will keep in touch with its clients throughout the whole purchase cycle. They provide customers with excellent pre-sale service, sale service and after-sale service.

Geographical Location

China is not exactly a small country where manufacturers are located in different cities and the specialization of factories varies from region to region.

For instance, Nanjing-which is located in southwestern Jiangsu, is the second-largest city in East China-has developed into a major city in the Energy Saving Technology industry.

Nanjing has fostered a distinctive ecosystem to support the manufacturing supply chain, and as a result, many excellent socially responsible micro lab extruder factories have emerged there, Granuwel micro lab extruder factory is one of them.

Document Check

Business licence

In China, all registered businesses carry a business license. The business license contains important information about the supplier, including the scope of their business.

This is a statement describing the supplier’s activities and an indication of if they are a manufacturer or a reseller. Production” and “assembly” identify a manufacturer, while “wholesale” and “distribution” indicate a trading company.

Certificates

A good way to check a micro lab extruder factory’s credibility is through their certificate. A quality management certificate (ISO 9001) implies that the supplier complies with certain statutory and regulatory requirements and has passed the relevant audits.

A social responsibility certificate shows that their workplace is safe and ethical. Environmental certificates show that their processes do not damage the environment. For social responsibility and environmental certificates, suppliers are required to pass a professional audit.

Step 3: Contact the manufacturers you have selected

You’ve already done your research and selected a shortlist of micro lab extruder factories, so what’s the next step?

Here are some considerations for communicating with a few of your selected suppliers to check whether they can meet your business requirements.

How Can I Distinguish Between Different Types Of Denim (Denim Fabrics)?

Between Different Types Of Denim Fabrics

Denim is a garment that can be worn all year round. How to distinguish between different types of denim (denim): Firstly, according to the thickness of denim, it is divided into 4.5 amps, 6 amps, 8 amps, 10 amps, 11 amps, 12 amps, 13.5 amps, 14.5 amps, etc. 4.5 amps are fragile and are commonly used in summer for women's vests, sleeveless garments, etc. 14.5 amps are already very thick. In winter, men's cotton jackets can be lined with cotton.Most of the jeans we often wear start at 8-12 A.

In terms of the type of denim fabric, it can be divided into plain, twill, herringbone, interwoven, bamboo, dark, flocked, etc.

In terms of composition, denim is available in 100 percent cotton, stretch (Lycra), cotton and linen blends, and tencel.

At present, the famous denim varieties at home and abroad are mainly Yuan Bao silk denim, warp, and weft bamboo denim, super indigo-dyed denim, jacket color, what color denim, warp, and weft stretch denim, etc.

1. Ring spun yarn denim

With the development and application of new technology equipment such as ring spinning, high speed, large rolls, good contact, knotless yarn, etc., the short length of thick spinning, low production efficiency, knots, and other shortcomings are solved.

The situation of denim yarns being replaced by air-flow yarns is rapidly changing, and ring spinning yarns are making a comeback.

The ring yarn denim has some superior properties to those of air-flow yarns, such as feel, suspension, tear strength, etc., and because of the psychological influence of people returning to nature and pursuing originality in the development of denim styles. This is in line with today's need for individuality in denim.

In addition, the ring spindle can be used to weave short, dense bamboo knots, which is a popular feature of denim.

2. Bamboo denim

The design of bamboo yarns with different yarn grades, different thicknesses (about the baseline), lengths and distances of bamboo joints, in the single warp direction, single weft direction, warp, and weft bi-directional configuration, and with the appropriate design of ordinary yarns of the same or different grades, allows for the production of a wide variety of bamboo denim. Which, after washing and processing, results in a variety of blurred, well-defined stripes.

In the early days, most of the bamboo denim was made from ring-spun bamboo yarn, which was spun in short lengths, with a slight pitch and relatively high density to create a dense decorative effect on the fabric, mainly leading to the bamboo knots.

In line with the evolving consumer demand, warp and weft bi-directional denim are now famous, especially bi-directional denim products with weft elasticity, which are very popular in domestic and international markets.

You can make some grades with a single rate of ring spindle thread and a suitable proportion of bamboo thread in the weft direction, provided that the tissue structure is well designed.

3. Weft stretch denim

The use of polyurethane elastomeric yarns has led to a new dimension in the development of denim varieties, making denim garments comfortable to wear. With the help of bamboo knots and colors, denim products can be adapted to fashionable and personalized consumer needs, with great potential for development.

At present, elastic denim is mostly weft stretchy, with an elongation of 20-40%. The amount of extension depends on the fabric design. The tighter the weft, the less flexible it is, and the faster the weft to a certain point.

In addition, the problem of weft shrinkage in the finished stretch denim fabric is currently too significant, generally above 10 %, with some cases reaching 20 % or more.

The solution is not to increase the product's elasticity in the product's design, which is generally 20-30% but to maintain a certain tension in the warp and weft against the tissue and increase the pressure in the pre-finishing width of the fabric shrinks considerably. The finished fabric has a low residual shrinkage in the weft.

4. Specialty fiber

Super indigo-dyed or unique dark indigo-dyed denim produces garments that are sharpened to give a special effect of rich, bright colors that are very popular with consumers.

Super indigo-dyed denim is characterized by a particularly deep dyeing and excellent colorfastness.

The former means that the amount of indigo dye dyed per unit weight of yarn (in general, % of the dry weight of the thread, referred to as % dyeing depth) is exceptionally high. e.g., typical denim fabric is dyed 1% to 3% deeper by indigo dyeing of the yarn, while super-indigo dyeing depth is more than 4%.

The latter means that super-indigo dyed denim needs to be washed repeatedly for more than 3 hours. However, the color still reaches or exceeds the color depth of everyday dyed denim when it is not passed, and its color is much brighter than relaxed dyed denim.

For blue-dyed denim, the fastness of polishing depends essentially on the degree of transmission of the dye through the threads, not on the fastness to the polishing of the paint itself (blue wet polish fastness is only graded 1), i.e., the better the transmission, the better the fastness to polishing.

In the past, the so-called indigo-dyed fast-wash technique was, in fact, a deliberate attempt to make the indigo dye lighter to the core of the fiber during the yarn dyeing process. The method requires a remarkable degree of core penetration of the paint, resulting in a deep, bright color after the denim polishing process.

The dyeing depth of super-indigo dyed denim products is increased by more than 60 % compared to conventional denim dyeing. The concentration of indigo in the dye solution is doubled to 3-4 g/L, making it possible to obtain deep colors.

This increases the viscosity of the dyeing solution, resulting in poor flow, which affects the ability of the dye to penetrate the cryptic chromophores and reduces the polish fastness of the denim, which does not meet the final depth required for garment production.

As a result, some companies design to increase the dye depth again, increasing the concentration of indigo in the dye solution again, which deteriorates the penetration performance and creates a vicious circle of back and forth, not meeting the requirements of super indigo color.

The higher the concentration of indigo in the dye, the heavier the color's redness, the darker the color, and the lack of super-indigo effect.

For this reason, many manufacturers are now ready to modify their dyeing equipment to solve this problem by increasing the number of dyeing passes.

For example, increasing the number of dyeing passes to 8, or even 10, not only increases the investment costs, the consumption of dyeing materials, the operational difficulties, and the environmental pollution.

An excellent way to solve this contradiction is to reduce the amount of insurance powder and alkali. Especially the control of the amount of alkali so that the pH value of the dyeing solution is stable between 11 and 12, the dyeing rate is the highest, the color is durable, and the dyeing tension of the gauze is reduced appropriately to obtain an excellent super blue diamond dyeing effect.

📷

5. Colour matching denim

Various denim varieties are now prevalent to increase the color and light variations of the indigo denim variety.

For example, indigo over-dyed sulfur black, indigo over-dyed sulfur grass green, sulfur black green, sulfur blue, etc., to meet the personalized needs of the market.

At the same time, denim mills have patented new varieties of denim to increase their competitiveness in the market.

In this regard, we should pay attention to controlling the concentration of the masterbatch as much as possible to prevent excessive spillage of contaminated liquor, which wastes pollutants and expands the pollution of the environment.

6. Color denim

There are mainly bromine indigo (commonly known in the market as emerald blue) denim and sulfur black denim, as well as coffee, emerald green, grey, khaki, sulfur blue denim using a combination of sulfur dyes, and a small amount of red, peach, toffee denim dyed with appropriate dyes and reactive dyes, etc. The production volume is small, but the market demand is urgent.

The main problem is that the color light is unstable, the dyeing is poorly valued, and the garment factories are not satisfied. This is related to the small production batch and the large variety of colors. Still, the dyeing and slurry combination machine has difficulties producing any color variety, consumes a lot, costs a lot, and has problems in sewage treatment.

One solution is to design the machine to minimize the number of color combinations using as few as possible two color combinations and no more than three. Or to use other stable dyestuffs instead to adapt to the dyeing line's production characteristics and obtain a long-lasting dyeing result. Or to solve the problem once and for all by using The color weaving plant is ideal for the production of mixed-color denim using a high-capacity yarn dyeing and warping process.

Talk about how to sew denim on a car.

This is the key to designing a denim garment.

Turning threads: mostly 2-minute single-sided, 2-minute single-sided, 2-minute double-sided, generally earthy yellow (and other clashing threads), but also color-coordinated threads; note the color-coordinated threads after washing.

Special technical threads, such as the word thread.

Thicker hand embroidery threads.

Materials:

denim, I-buttons, four-way buttons, studs, cockles, picks, metal zips, etc.

Markings:

these include central markings, size markings, wash markings, markings, side markings, etc.

Denim is the problem of denim shrinkage. The denim factory master is the busiest; ordinary denim also has 2-3% horizontal shrinkage, elastic denim shrinkage reaches more than 10%. Each roll of denim is different, so the denim master's version will never end.

Generally speaking, there is a lot of casual denim, mainly cut on a flat surface, and sizing is significant.

Stretch denim (including Lycra) is tricky; it's mainly used for women's slim-fitting jackets, flattering low-waisted jeans. With the shrinkage of 10% or more, the shape is constantly being adjusted. And the most crucial thing about jeans is that they don't wrinkle at the front; they need to fit snugly. In the last two years, some of the biggest brands have released three-dimensional silhouettes, as we learned with the stand-up cut, with many wrinkles on the knees.

7. The technique of embellishment in denim

The last two years have seen a departure from previous denim trends, not only in terms of variations in washes but also in the techniques used to embellish jeans.

Burr:

the leg of the jeans, the trousers trimmed with scissors, plus remarkable thread embroidery, including computerized embroidery designs.

Hot drill:

this is popular with the Russian market for applique embroidery, hand embroidery, bead embroidery, and technical designs.

Glue printing:

hard to the touch, wash easily, and peels off.

Laser:

burns off all the colors of the cloth to reveal the color of your fabric, and can also be used with wool, faux leather, corduroy, thick knit (fleece, sanitary), and other fabrics.

Many different designs can be made for denim.

Jeans, denim shirts, denim jackets, skirts, coats, etc., are places to express your creativity and talent.

Injection Moulding Defects & Their Preventions

 1. Weld lines

Weld lines can appear on the surface of a molded part where the molten material has converged after splitting off into two or more directions in a mold. The hair-like weld line is the result of weak material bonding, which lowers the strength of the part.

Common causes of weld lines and how to prevent them:

Two or more fronts of polymer or other molten material need to maintain a certain temperature when colliding. injection molding defect Otherwise, they become partially solidified and won’t sufficiently bond where they meet, resulting in weld lines. Common remedies for weld lines in molded parts include:

Increase material temperature to prevent partial solidification

Raise injection speed and pressure to limit cooling before the material has filled the mold

Redesign the mold to eliminate partitions

Switch to a material with a lower melting temperature or viscosity to allow faster flow and prevent early cooling

2. Jetting

Jetting refers to a kind of deformation in a molded component that can occur when there’s an initial “jet” of molten material injected into the mold cavity that starts to solidify before the cavity is filled. Jetting often appears as a squiggly line in the surface of the finished component, typically leading from the initial gate of injection. This visible flow pattern can result in part weakness.

Causes and remedies of jetting in molded parts:

The chief cause for jetting is excessive injection pressure. injection molding defects When molten polymer or other material is injected through a small gate at high pressure it often squirts rapidly through the gate, rather than filling the mold cavity gradually. As this initial line of material cools against the mold walls and starts to harden, the remaining mold material pushes it, leaving impressions in the surface of the finished part. Avoid jetting in molded parts by:

Reducing injection pressure to prevent rapid squirting of the material into the mold cavity

Increasing material and mold temperature to keep the initial jet of material from solidifying early

Designing the mold with the injection gate located such that the material is directed across the mold, rather than lengthwise

DEFECTS TYPICALLY RELATED TO MATERIAL USE OR STORAGE

Injection molding defects can often originate from the material itself or how the manufacturer stores and handles the material prior to the production process. These defects can range from minor aesthetic issues to compromised strength of the finished component. Serious safety concerns may also result, depending on the intended application of the product affected.

3. Discoloration

Discoloration, or “color streaking”, occurs when a molded part is a different color than intended. Often the discoloration is limited to a localized area or a few streaks of abnormal color on a molded part. This defect typically affects the appearance of the part without reducing its strength.

Causes of discoloration in molded products and how to prevent it:

A common cause of discoloration is leftover pellets in the hopper or residual resin in the nozzle or mold from a previous production run. injection molding defects Poor thermal stability of the coloring agent or improper mixing of the masterbatch are other potential causes. Take the following precautions to limit the risk of discoloration in your injection-molded products:

Ensure that workers properly clean the hopper, nozzle and mold between production runs to eliminate any residual pellets or base material

Consider using a purging compound to remove excess color from the machine

Ensure you or your supplier is using a color agent with adequate thermal stability

Ensure that the masterbatch is evenly mixed for consistent color output

4. Delamination

If you find thin layers on the surface of a molded part are easily separating or peeling off the underlying material, you’re seeing a molding defect called delamination. Delamination is a defect characterized by a flaking surface layer, similar to what you’d commonly find on flake mica. This is generally regarded as a relatively serious defect because it reduces the strength of the component.

Apart from Plastic Toy Mould Exporters We're also dealing in Plastic Toy Injection Mould Manufacturer And Plastic Toy Blow Mould Manufacturer & Etc.

Causes and prevention of delamination in injection molding:

The most common cause of delamination is contamination of the resin pellets or other base material with a foreign material. Flaky separation results when the two materials cannot properly bond to each other. For example, you might combine a common base plastic like acrylonitrile butadiene styrene (ABS) with an incompatible plastic, such as polypropylene (PP). The resulting loss of strength of the material would be very dangerous if your part is intended for a safety-critical use.injection molding defects

Aside from material fed into the hopper, the contaminant could also be any excess release agents coating the mold for easier component separation. Excess moisture on the material, due to improper drying prior to use, can also cause delamination. Consider the following corrective actions to prevent recurrence if you discover delamination affecting your molded parts:

Increase the mold temperature or pre-dry the material properly if excess moisture is an issue

Ensure workers are properly storing and handling the resin pellets or base material to prevent contamination

Consider redesigning the mold with a focus on the injection nozzle to limit your dependence on release agents

INJECTION MOLDING DEFECTS CAUSED BY POOR MOLD DESIGN OR MAINTENANCE

Defects can be introduced into molded products by issues with the mold tooling itself. Certain defects are likely to occur when the mold is poorly maintained or designed. Especially in the latter case, these defects can be difficult or costly to address in future production runs when it’s necessary to completely overhaul the mold.

5. Short shot

A short shot occurs when the flow of molten material doesn’t completely fill the cavities in a mold. The result is that the molded component is incomplete after cooling. Short shot might appear as incomplete compartments in plastic shelves of a display or missing prongs on a plastic fork, for example. Short shots are typically classified as a major defect that can inhibit the function or appearance of the molded part.injection molding defects 

Causes and remedies of short shot in molded products:

The most common cause of short shots is flow restriction resulting from narrow or blocked gates. Sometimes the material is too viscous or the mold is too cold to allow the molten material to completely fill the mold before cooling. And other times trapped air pockets may be hindering proper flow or injection pressure may be inadequate. Consider the following steps to prevent short shot:

Redesign the mold with wider channels or gates for better flow

Increase injection speed or pressure or choose a thinner base material to improve flow

Increase mold temperature to prevent material from cooling too rapidly

Add additional air vents or enlarge existing vents in the mold to allow trapped air to escape

6. Flash

Flash, also called “spew” or “burrs”, is an excess of molding material that appears as a thin lip or protrusion at the edge of a component. Flash appears because material has flowed outside of the intended flow channels and into the space between the tooling plates or at the injector pin. injection molding defects Flash is usually subtle but might be considered a major defect if particularly obvious on a product. The process for reworking a molded product with flash often includes trimming the excess material.

We R D Mould & Industries are a renowned  Plastic Toy mould manufacturer in Ahmedabad,Gujarat, India,  provide various types of  Plastic Toy Mould Including  Plastic Toy Injection Mould, Plastic Toy Blow Mould & Etc.

Common causes of flash and prevention in molded products:

A poorly-designed or worn and degraded mold is the most common contributor to flash. Excessively high mold temperature or injection pressure can also cause flash. Material flowing through the mold cavities can force its way between plates when plate clamping force is inadequate. Common methods for addressing flash in molded products include:

Retool or redesign the mold if plates don’t fit together properly or allow material to flow outside the channel

Increase plate clamping force to confine material flow to the channel

Adjust mold temperature, injection pressure and ventilation to improve material flow

CONCLUSION

Manufacturing using injection molding typically requires significant upfront investment in tooling. That’s why it’s especially important to design your mold right the first time, rather than having to start again after finding serious defects. Defects related to the moulding process or material tend to be easier and less costly to solve. But no matter the cause, defects in molded products can hurt your bottom line tremendously.

Now that you’re familiar with common injection molding defects to look out for, you can take steps to prevent them in the future and ensure your products meet your customers’ quality standards.
