Solution For Sink Mark, Warping In TPE Overmoulding

Most styrene series TPE have a high molded shrinkage that causes the laminated composite to contract more than the substrate (typically PP,ABS,PC,PA, etc.), resulting in bending or warping of the substrate parts. This is especially true for long, thin parts, or parts with a substrate thickness thinner than the coating, or for substrate materials with a lower modulus of elasticity.

This situation can be handled in the following ways:

Selection of TPE materials:

Adopt matrix materials with higher elastic modulus.

Add reinforcing rib […]

Notes for PA Injection Molding

Characteristics of PA: Nylon has the characteristics of toughness, wear resistance, self-lubrication, smoothness, non-toxicity, anti-bacterial and strong water absorption. In addition, its tensile strength and stiffness will decrease sharply with moisture absorption. Then, the size of the finished product varies greatly.

Advantages of PA:

It has high mechanical strength, good toughness, high pressure resistance and elongation strength, twice as much as ABS injection parts.

Nylon injection parts have excellent fatigue resistance, smooth surface, small friction coefficient and good wear resistance. It also […]

NC Processing Flow of Injection Mold

CNC center has been widely used in the current market. Compared with other machine tools, the mechanical part of CNC center is not different from other lathes, only in the form of control. So how does the CNC machining center work?

CNC machining center is also called CNC machine tool. Generally speaking, the sequence of CNC processing technology should satisfy the following rules:

Milling before drilling

Processing the inner cavity first, then the contour.

According to the sequence of working procedures, tool diameter […]

What performance is required when using injection mold steel materials?

In the process of injection mold processing, the selection of raw materials will play an important role in the overall life of the injection mold and the quality of the plastic products produced. What performance requirements should be achieved when selecting the steel materials for injection molds?

Good surface hardness and wear resistance

The hardness of the injection mold is usually below 50-60HRC. The surface hardness of the heat-treated mold is high. The mold is subjected to large compressive stress […]

Why do we choose injection moulds to produce products?

The sustained development of the plastic industry has also promoted the development of the injection mould industry, so why is the injection mould so popular? The following six points are enough for you to have a basic understanding of injection moulds.

1) High accuracy

As a highly precise processing method, plastic injection moulding process can be used to produce almost any kind of diversified plastic parts. Although there are some design limitations, the manufacturing of injection moulds ensures the high precision […]

Sensor injection accessories copper nuts +ABS processing

Injection molding process is not static, logical, because of the different products, different materials, different injection molding machine and material preparation and so on the different conditions, injection molding process will produce many uncertain factors, so as the injection molding processing workers, according to specific conditions to the corresponding process optimization adjustment is the highest embodiment of injection molding processing technology. Therefore, the processing optimization of injection parts of sensor copper nut +ABS can be carried out from the […]

How to solve the matte surface of plastic injection parts?

Low glossiness means that the surface is dark and dull, and the transparency of transparent products is low. There are many reasons for poor glossiness. Generally, the surface gloss defects of products can be divided into three types: plastic mold failure, improper forming conditions and improper use of raw materials.

Injection Mold Failure

Because the surface of plastic parts is the reappearance of the cavity surface of plastic mold, if there are scratches, corrosion, micro-holes and other defects on the surface […]

Causes of flash edges in injection products

Why do injection products flash? Flash burr may occur during injection molding, which is largely due to the failure of mold or machine clamping force. It affects the quality of the product, we need to understand the cause of flash.

Why do injection products flash?

The material temperature is too high

For low viscosity melt materials such as polyamide, if only by changing the molding conditions to solve the spillage defect is very difficult, spillage, should consider appropriate to reduce the […]
