New Developments in Domestic Injection Moulds

https://www.tangrammould.com/LED-Linear-Strip-Lens-Mould.htmlIn recent years, the rapid development of domestic injection moulding technology is mainly manifested as:

1. Mould integration manufacturing and technology promotion. In addition to the functions of automatic feeding, stamping, laminated core thickness measurement, grouping and product output, moulds also have a combination of hinge assembly connection, complex structure, mould heating, forging, thermal (tissue) control, local mould welding, tapping, internal local injection, mould cutting and mould testing technologies. New technological changes such as motor cores mark a new era of integrated mould manufacturing units. Mould products, such as LED linear strip lens mould continue to develop toward large, fine, high-performance, integrated manufacturing.

2. The commercial Internet extends to moulds and their industrial chain. Tangrammould is an advanced model for the production and sale of LED linear strip lens moulds.

3. Smart moulds. At present, in the plastic mould and die-casting mould industry, there are mould cavity pressure, temperature, flow, cooling process intelligent control mould. In addition, the intelligence of mould processing equipment is also rapidly promoting the intelligent manufacture of LED linear strip lens moulds.

4. mature large-scale progressive die technology, high speed and reliability has become an important feature of precision grade moulds. At present, large continuous stamping parts are everywhere, and the size of the parts is getting larger and more complex shape, indicating that large continuous stamping technology has entered a mature stage. However, precision progressive dies require increasingly high levels of stability and reliability. Obviously, ultra-precision parts and small parts of the mould design and manufacturing technology have become a hot spot for mould enterprises Tangrammould produces LED linear strip lens mould.

5. mold standard parts tend to be constantly improved.

Injection Moulding Units and Maintenance

https://www.tangrammould.com/TV-and-Computer-Socket-Mould.htmlThe injection unit is the device that causes the resin material to be heated and melted and then injected into the mould. The resin is squeezed from the head into the barrel as shown in the diagram and the melt is conveyed to the front of the barrel by the rotation of the screw. In that process, the resin material in the barrel is heated under the action of the heater, and the resin becomes molten under the action of the shear stress of the screw, which will be equivalent to the moulded product and the main flow channel, and the molten resin of the diversion channel is retained in the front end of the barrel (called metering), and the screw's continuous forward injection of the material into the mould cavity.　As the molten resin flows through the mould, the speed of movement of the screw must be controlled (injection speed) and controlled with pressure (holding pressure) after the resin has filled the mould cavity. When the screw position and injection pressure reach a certain value we can switch from speed control to pressure control.

How to maintain injection moulds?

1, processing companies should, first of all, equip each pair of TV and computer socket mould with a resume card, detailed records, statistics on its use, care (lubrication, cleaning, rust prevention) and damage, according to which you can find out which parts, components have been damaged, the degree of wear and tear, in order to provide information to find and solve problems, as well as TV and computer socket mould's moulding process parameters, product materials used to shorten the mould's trial run time and improve production efficiency.

2, processing enterprises should be in the normal operation of the injection molding machine, computer socket mould, test computer socket mould a variety of performance, and the final molded plastic size measurement out, through this information can determine the existing state of the mold, to find out the cavity, core, cooling system, and parting surface damage, etc., according to the plastic parts to provide Based on the information provided by the moulded part, the damage status of the computer socket mould can be determined as well as the maintenance measures.

3, to TV socket mould several important parts to focus on follow-up testing: ejector, guide parts to ensure that the mould open and close movement and plastic parts ejected, if any part of the damage and stuck, will lead to production stoppage, so should always keep the TV socket mould ejector pin, guide column lubrication (to choose the most suitable lubricant), and regularly check the ejector pin, guide column, etc. After completing a production cycle, the working surfaces, moving and guiding parts of the TV socket mould should be coated with professional anti-rust oil, and particular attention should be paid to the protection of the bearing parts of moulds with gears and racks and the elastic strength of spring moulds to ensure that they are always in the best working condition; as production time continues, the cooling channels are prone to deposits scale, rust, sludge, and algae, etc., so that the cooling runner cross-section becomes smaller, the cooling channel becomes narrower, greatly reducing the heat exchange rate between the coolant and the mould, increasing the production costs of enterprises, so the cleaning of the runner should be given attention; for hot runner moulds, heating and control system maintenance is conducive to preventing the occurrence of production failures, so it is particularly important. Therefore, after each production cycle should be TV socket mould on the band heater, rod heater, heating probe, and thermocouple with ohmmeter measurement, if there is damage, it be replaced in a timely manner, and with the mould resume to compare, make a good record, in order to find the problem in due time, take countermeasures.

4, to pay attention to the TV socket mould surface maintenance, it directly affects the surface quality of the product, the focus is to prevent rust, therefore, the choice of a suitable, high-quality, professional anti-rust oil is particularly important. When the mould has completed the production task, according to different injection molding should take different methods to carefully remove residual injection, available copper rod, copper wire, and professional TV socket mould cleaning agent to remove residual injection and other deposits in the mould, and then air dry. It is forbidden to use hard objects such as iron wire and steel bars to clean up the surface so as not to scratch it. If there are rust spots caused by corrosive injection moulding, use a grinding machine to grind and polish, and spray with professional anti-rust oil, then store the mould in a dry, cool, and dust-free place.

As a professional mould manufacturer, Tangrammould has a high reputation in the industry, mainly producing TV socket moulds and computer socket moulds. After this article teaches us the maintenance methods of TV and computer socket moulds, we should pay more attention to the daily maintenance of moulds.

Precautions for Mould Polishing

https://www.tangrammould.com/Fan-Speed-Controller-Switch-Mould.htmlFan speed controller switch mould polishing has two purposes; one is to increase the finish of fan speed controller switch mould, so that the surface of the products out of the mould is clean, beautiful and aesthetic, the other is that the mould can be easily demoulded, so that the plastic is not stuck to the mould and can not be taken off.

Fan speed controller switch mould polishing should pay attention to the following matters:

(1)When a new mold cavity starts processing, the surface of the workpiece should be checked first, and the surface should be cleaned with kerosene so that the oil stone surface will not stick to the dirt leading to the loss of cutting function.

(2)When grinding the coarse grain should be done in the order of difficult first and then easy, especially some difficult to study the dead angle, deeper bottom to be ground first

(3) part of the workpiece may have more than one group together to study light, to first separately study the coarse grain of a single workpiece or sparkle, after all the workpiece together to smooth research.

(4) large plane or side plane of the workpiece, use oil stone grinding to remove the coarse grain and then use a flat steel piece to do light transmission detection, check whether there is uneven or inverted buckle of the bad situation, such as inverted buckle will lead to difficulties in the release of the parts or the parts strains.

(5) in order to prevent attention to the mold workpiece research out of the buckle or have some laminating surface need to protect the situation, available saw blade paste or use sandpaper on the edge, so that you can get the ideal protection effect.

(6) grinding fan speed controller switch mould plane with back and forth pull, dragging oil stone handle as flat as possible, do not exceed 25 °; because the slope is too large, the force from the top downward impulse, easy to cause the research out of many coarse lines on the workpiece.

(7) If the plane of the workpiece with a copper or bamboo sheet pressed against the sandpaper polishing, sandpaper should not be larger than the area of the tool, otherwise it will grind to where it should not grind.

(8) The shape of the grinding tool should be close to the same shape as the surface of the fan speed controller switch mould, so as to ensure that the workpiece is not deformed by the research.

If you do a good job of the above points, then fan speed controller switch mould polishing appearance will be beautiful.

The Structure of The Plastic Mould

https://www.tangrammould.com/The plastic mould structure mainly consists of a concave mould with variable cavities consisting of a concave mould combination substrate, a concave mould assembly and a concave mould combination plate, and a convex mould with variable cores consisting of a convex mould combination substrate, a convex mould assembly, a convex mould combination plate, a cavity cut-off assembly and a side cut-off combination plate.

In order to improve the performance of plastics, various auxiliary materials such as fillers, plasticisers, lubricants, stabilisers and colourants are added to the polymer to make it a good performing plastic.

1、synthetic resin is the most important component of plastics, and its content in plastics is generally 40% to 100%. Because of the large content and the fact that the nature of the resin often determines the nature of the plastic, people often see resin as synonymous with plastic. For example, polyvinyl chloride resins are confused with polyvinyl chloride plastics and phenolic resins with phenolic plastics. In fact, resin and plastic are two different concepts. Resin is a raw, unprocessed polymer that is used not only to make plastics but also as a raw material for paints, adhesives and synthetic fibres. The vast majority of plastics, in addition to the main component resin, require the addition of other substances to make big piano-key switch plastic mould.

2、Filler

Fillers are also called fillers, which can improve the strength and heat resistance of plastics, and reduce costs. For example, the addition of wood flour in phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheapest plastics, but also significantly improve the mechanical strength, but also improve big piano-key switch plastic mould quality. Fillers can be divided into organic fillers and inorganic fillers two categories, the former such as wood flour, rags, paper and a variety of fabric fibres, etc., the latter such as glass fibres, diatomaceous earth, asbestos, carbon black, etc.

3、Plasticizers

Plasticizers can increase the plasticity and softness of plastics, reduce brittleness, so that plastics are easy to process molding. Plasticizers are generally miscible with resin, non-toxic, odourless, light and heat stable high boiling point organic compounds, the most commonly used is phthalate esters. For example, in the production of PVC plastics, if more plasticizers are added, soft PVC plastics can be obtained; if no or less plasticizers are added (dosage <10%), rigid PVC plastics can be obtained.

4、Stabilizers

In order to prevent the decomposition and destruction of synthetic resins by light and heat during processing and use, and to extend the service life of big piano-key switch plastic mould, stabilizers are added to the plastic. Commonly used are stearate, epoxy resin, etc.

5、Coloring agent

Coloring agents can make big piano-key switch plastic mould have a variety of bright, beautiful colours. Organic dyes and inorganic pigments are commonly used as colorants.

6、Lubricant

The role of the lubricant is to prevent the plastic from sticking to the metal mould when forming, and at the same time can make the surface of the plastic smooth and beautiful. Commonly used lubricants are stearic acid and its calcium and magnesium salts. In addition to the above additives, the plastic can also add flame retardants, foaming agents, anti-static agents, etc.

As a professional big piano-key switch plastic mould manufacturer, Tangram Mould Manufacturing Company has professional technicians with excellent skills and mechanical equipment to occupy its own business territory in the manufacturing of big piano-key switch plastic mould.

Is There Really No Future In The Plastic Mould Industry?

https://www.tangrammould.com/Decorative-Round-Batten-Holder-Mould.htmlI saw a person in the plastic mold industry said a few days ago: “I really don’t want to make decorative round batten holder mould . There are too many people who make decorative round batten holder mould. I don’t know what to do when I change my job, and I’m very confused now.”

In recent years, due to various reasons in the plastic holder mould industry, the development of the plastic holder mould industry has faced many difficulties; especially the majority of migrant workers have the most profound experience, wages cannot rise, rising prices and lower purchasing power. There is also fierce competition among enterprises. Order prices are falling, but employee wages and prices are rising. It is indeed difficult and unsatisfactory. In such an environment, most people have doubts, is the plastic mold industry declining? Is there a future for plastic holder moulds? Before discussing this issue, listen to a senior mold engineer’s analysis of molds in the entire manufacturing industry. Positioning in China, this issue naturally clears its prospects.

Positioning of plastic holder moulds in the manufacturing industry: Molds are the mother of industry. Nowadays, most plastics and plastic products are produced with molds. Only with molds can the products reach mass production, improve efficiency, and reduce costs. Modern is a world of high-speed industrialization, and there is no way to leave the mold. In other words, mold is one of the most important cornerstones of the industrial world, and it is an industry that cannot be eliminated. Especially in the current era of rapid development of China’s industrialization process, the plastic holder moulds industry is still a sunrise industry, and it is still an industry full of opportunities!

The status of the plastic holder moulds industry: There are several factors that lead to the current dilemma of the plastic holder moulds industry. The first is the market environment. Since the 2008 financial crisis, the crisis has never left. These factors have caused the manufacturing industry to encounter difficulties. As one of the core industries of the manufacturing industry, the plastic mold industry will naturally be directly affected. Decrease, lower profits, for people engaged in the plastic holder moulds industry, it directly affects income. In addition to the overall world pattern, the continued economic downturn in Europe, the United States and other countries has also directly affected our mold industry, because the molds with higher profits in the entire mold industry are basically export molds. If there are fewer exported molds, profits will naturally be less. If the boss can’t make money, the salary will naturally not rise. This is an external and objective factor.

It is difficult to change this factor in the short term, and it is basically impossible. Therefore, in the past two years, many small workshops and individual mold manufacturers cannot maintain and have to close their doors. However, the development of everything is cyclical. The current trough is only temporary. The overall trend of China’s economy will not change. The difficulties caused by this will certainly be gradually eliminated in a short period of time in the future. Therefore, There is actually nothing to worry about for this factor, after all, the mold industry is a basic industry. Decorative round batten holder moulds are indispensable to industry, just as catering is to people’s livelihood.

As a professional manufacturer with many years of experience in the industry, we Tangrammould are confident in the quality of our products.
