How High-Quality Parts are Manufactured by Injection Molding?

Injection molding is used for making production parts in large volumes, generally millions. The process is very simple; however, it requires a proper understanding of using the right pressure and equipment to achieve the best results. The injection molding process makes use of extreme pressure and temperature to sufficiently fill the interior with liquid polymer or molten plastic. They are then cooled after release. The completed part is then processed. However, to carry on with the process safely, you will require the right components. It will be better to search for injection molding parts production components to find a company that can provide you with the same.

Injection molding parts process

It is vital that the injection molds have got high precise match which must be between the two molds to perfectly control the material flow. When creating the mold, one needs to be extremely careful about getting a precision product. The injection molds are typically constructed using aluminum steel and then a precision machine to form the desired product.

Plastic parts manufacturing is a repetitive process. Once you have achieved errorless and functional mold, it will come with a low screen rate relative to the other process, like CNC machining, which cuts a considerable portion of the original material.

Once you are successful with the first, the second one will be identical. This happens due to the ability for manufacturing multi-cavity injection mold parts. There is a possibility that some of the custom complex parts can encounter a problem during the injection molding process, like surface defects. Thus the molded parts must be designed carefully, and the planning must be done in consideration to make any changes in geometry.

Given the benefits the process can provide for manufacturing quality products for different industries, the injection mold components demand has increased greatly. This will assure proper efficiency of the equipment used during the process. This has made it easy to find the right experts who can deliver the desired amount of components required for the job.

Injection Molding Flash: Causes and Prevention

One of the most common injection molding defects in the plastic manufacturing industry is injection molding flash. In injection molding, flash is a thin film of plastic that escapes from the mold cavity. Usually, injection molding flash happens at the mold’s parting line or between ejector pin locations and inserts. Before packing or turning to the next treatment process, the plastic injection molding manufacturer should remove the plastic flashing.

Here, we highlight the main causes of injection molding flash and how you can prevent it:

What causes flashing?

There are a number of causes of flash, including uneven flow, low viscosity, low clamping pressure, improper venting, and parting line mismatches. While some of these problems are related to tooling, others are a function of processing.

Uneven flow and low viscosity

Processing conditions may cause plastics to fill the mold too rapidly or flow too readily—for instance, excessive use of coolants, residual moisture from insufficient drying, long residence times, and extremely high melt temperatures can cause this.

Low clamping pressure

While the pack/hold phase of injection molding ensures the cavity is filled perfectly, it can also force the mold open. If the clamping pressure is too low, plastic may leak from the mold even if the mold halves fit tightly together.

Improper venting

Worn, old vents may not meet required tolerances and allow too little or too much air to escape. Thin vents may permit more fluid materials to pass through and vents that aren’t too deep may enable firmer plastics to protrude.

Parting line mismatches

Residues, contaminants, dirt, and dust can keep the injection mold halves from closing properly. Plus, worn mold cavities won’t fit together tightly. Pressure may also distort the metal surfaces of mold plates, and intricate part geometries may complicate closure.

How to prevent and reduce flash?

DFM (design for manufacturability) is an important component of flash prevention and reduction. For instance, the guidelines of plastic injection molding recommend placing the parting line along the edge of the part instead of on a flat surface to improve both the function and appearance of the part. While this practice helps you hide the seam, it also mitigates the probability of flash formation.

During the design phase, your part drawing may indicate how little or how much flash you’ll accept. You have to consider a couple of measurements. Flash thickness measures perpendicular to the parting line while flash extension measures how much it projects from the plastic part along the parting line of the mold. The flashing’s location is also important and can tell you where you went wrong.

While reducing the thickness and extension of flash improves the quality of the part, it increases the costs of your part and mold. With strict flash removal requirements, you can specify a flash-less mold so that your plastic parts don’t have a lot of flashing. Yes, this type of mold can increase your tooling costs by two to three times, but removing flash during post-processing may be a little more cost-effective.

If your injection molding manufacturer is already using tooling, you can decrease flashing through process improvements and mold maintenance. For instance, when it comes to parting line mismatches, potential solutions may include cleaning mold surfaces, inspecting a cavity, and correcting a clamp misalignment. If the clamping tonnage isn’t high enough, an injection molding manufacturer may have to use a machine with a higher clamping force or reduce the pressure.

Fight flash with PTMS

Unfortunately, flash is part and parcel of the injection molding process. Nevertheless, by understanding the signs in advance and detecting problems beforehand, you can prevent flashing and save your time and money. While flash-free tooling means more upfront costs, you’ll get a massive return on investment a few years down the line.

If you’re using existing tooling, or if flash-free tooling sounds very expensive, the solution may be multifactorial — use different equipment, talk to your injection molding manufacturer about making process improvements, request mold cleaning and maintenance, and improve your part design.

There are a ton of things that can go wrong and increase flashing. However, a skilled partner can make things right. That’s why PTMS is the smart choice for your next injection molding project.

Application of 3+2 CNC Machining in Mold Making Factory

Plastic injection mold manufacturers have long embraced simultaneous multiple-axis machining on machine tools with five or more axes, but more and more China injection mold makers have begun machining mold components on multiaxis platforms in the past few years, said Charlie Chan, engineering manager HS Mold & Die Co.,LTD

He mentioned, however, that the common approach for machining mold parts in houses is 3+2, or 5-axis positional machining. According to his estimate, about 80% to875% of the multi-axis work is performed via 3+2 rather than simultaneous when cutting up to five sides of a prismatic metal workpiece in one fixturing.

What is 3+2 CNC Machining

3+2 (5 axis) CNC machining, also called “positional five-axis machining”, is a technique whereby a three-axis milling program is executed with the cutting tool locked in a tilted position using the 5-axis machine’s two rotational axes, hence the name, 3+2 machining. During the machining process, the fourth and fifth axes are used to rotate the cutting tool in a fixed position rather than to manipulate the tool continuously.  On a standard three-axis machine, the only part face that the CNC machine could cut with a cutting tool in its normal position is the horizontal face that faces directly at the spindle. 

3+2 CNC Machining Advantages

Compared to conventional three-axis machining, the main advantage of 3+2 CNC machining is the reduction of setup time. According to data from our mold making shop, we could save easily 20% to 25% in setup time because we don’t have to handle that part multiple times.”

Another big benefit of 3+2 CNC Machining is that it allows for the use of a shorter, more rigid cutting tool. With 3+2 machining, the spindle head can be lowered closer to the work piece with the tool angled toward the part surface.  This means that a good surface finish and more accurate dimensional results can be achieved .This helps to improve part accuracy by being able to position a work piece so that short, rigid cutting tools are applied, such as when producing undercuts in mold cavities and steep wall inserts in addition, with 3+2 machining, we can use standard, off-the-shelf tools

 Rather than using some custom, extra-long tool or holder and risk vibration, this helps to save money easily by 10% to 15% in injection mold costs because there is no need to use special tools for mold manufacturers in china, 3+2 Machining is an ideal option because they can use more off-the-shelf, standard catalog tooling. They have the freedom to reach into my part at different angles without using an especially long tool or special to make that feature on that part.

Application of 3+2 CNC Machining

Where applicable, 3+2 machining will save time and improve operations.This technique is more and more popular with mold making company because it offers great convenience while deep cavities or inserts in complex plastic molds that would otherwise have to be machined with long, slender tools or with tool extensions. Long, slender tools increase the risk of deflection or chatter and tool extensions can create clearance problems. Using 3+2 machining also allows undercuts in cavities and steep walls on standing mold cores to be machined directly. This technique might reduce or eliminate operations for electrical discharge machining (EDM).Relatively few parts are not suitable for 3+2 machining, including complex components. 3+2 CNC Machining is usually used to machine below parts:

deep cavities or inserts in complex plastic molds

certain types of parts from the solid rather than from a complex casting

Drilling holes of metal parts at compound angles such as  aluminum brake cylinders in a single setup

We are a China injection mold maker and our CNC machining center has both 3+2 and full 5 axis machining capability, capable of making prototypes and production parts as fast as one day.  Reach out HS Mold and see how we could benefit your next CNC rapid prototyping or low-volume manufacturing project.

The Influence of Plastic Mold Quality on Injection Molding Production

The purpose of mold design and manufacturing is for the mass production of injection parts with high efficiency and high quality, to produce high-quality plastic parts, the first mold is good, a good set of plastic molds is not just a good look, want to do a set of high-quality, high level, high precision plastic molds, from the following aspects.

1. The smoothness of the injection mold surface

The polishing of the mold surface is very important, which is one of the most important links to determine the success or failure of mold manufacturing. The surface of the mold is not smooth enough, its surface is uneven, and the surface of the plastic parts injected will have skin lines and sand grains. Generally, the polishing surface into a mirror is good, in addition to the choice of mold steel, grinding personnel, time, technology will have an impact on the polishing mirror effect, requiring a professional mold polishing master, experience to be particularly rich in order to accurately grasp the polishing time, to ensure the effect of mold mirror polishing.

2. Accuracy of mold

The precision of the mold determines the dimensional accuracy of the plastic parts, mold manufacturing must first have the conditions of high-precision measurement, such as quadratic detector, three-dimensional detector and other detection instruments, using the object imaging principle to accurately calculate the size and spatial position of the object, can detect the difference of 0.02mm, accurate measurement of product size and injection volume.

3. Fit degree of mold production

Although the mold industry has certain operating standards, the mold and injection molding of different mold manufacturers will have small differences, such as mold opening and injection molding are not the same manufacturer, due to the different mechanical equipment and production methods of various manufacturers, there will be risks in production, affecting product quality and production efficiency, in order to reduce this risk, generally choose to open mold and injection molding in the same manufacturer is better. From mold opening to injection molding manufacturers can control themselves, and problems can be solved in time.

RUBBER PARTS MANUFACTURER - HELPING WITH CUSTOM MADE RUBBER PARTS

Various types of rubber parts are absolutely essential for any kind of machine. But at times it is not possible for the machine manufacturers to access the exact kinds of rubber parts that they are seeking. In such cases, they either have to accommodate the available parts or have to opt for custom made rubber parts.

Custom made rubber parts used to be expensive earlier, but off late thanks to the effort of every rubber parts manufacturer these have become affordable and easy use. There is no denying that standard rubber parts are cheaper than custom made ones, any day. But incase getting a particular type and dimension of rubber part is extremely crucial to the process then getting it custom made albeit at a little higher price, would be the right decision. Also because in general rubber parts being inexpensive, going in for custom made parts for a machine manufacturer is not be a problem.

The Types of Custom Made Rubber Parts Offered By Rubber Parts Manufacturer

There are several types of rubber parts that can be custom made by the rubber parts manufacturer. Some of these are:

Seals

 O-rings

Flanged Stem Bushings

Grommets

Bumpers

Anti-vibration Pads

Tips & Caps

Extrusions & Tubing

Opting for standard rubber part is always the first choice for the machine manufacturers because it cuts down the time required for crafting a custom made one. But in instances wherein the standard rubber parts are very difficult to fit in, the manufacturers have to opt for the custom made ones. Generally in case of custom made rubber parts, the clients draft the design for the part themselves. But it is for the Rubber parts manufacturer to choose the right kind of rubber and factor in noise dampening and vibration isolation in the given design.
