How much do you know about the shrinkage of common plastic raw materials? Sep 21, 2020
How much do you know about the shrinkage of common plastic raw materials? Different plastic materials have different shrinkages. Today we will talk about the most commonly used material shrinkage. ABS : 0.5% PC: 0.5% PMMA: 0.5% PS: 0.5% PC+ABS: 0.5% PE : 2% PP : 2% PA: 2% PVC : 2% POM : 2% When we make plastic mold, we should consider the plastic material shrinkage, otherwise the product wil...

Injection mold gate type and selection-1 Sep 21, 2020
The gate of the plastic mold refers to a section of short runner connecting the runner and the strong, which is the entrance of the resin injection cavity. The shape, quantity, size and location of the gate in the mold will have a great impact on the quality of the plastic parts. Therefore, the selection of the gate is one of the key points of the plastic mold design. The gate will be introduced i...

2.1 Unrestricted gate. Unrestricted gate is also called straight gate. Its characteristic is that the plastic melt flows directly into the cavity, the pressure loss is small, the feeding speed is fast and the molding is easier, and it is suitable for all kinds of plastics. It has the advantages of good transmission pressure, strong pressure maintaining and shrinking effect, simple and compact mold...

2.2 Limit the gate. The cavity and the runner are connected by a channel with a short distance at one end and a small section. This channel is called a restrictive gate, which limits the thickness of the gate and rapid solidification. The main types of restriction gates are: 2.2.1 Point gate. Point gate is a round gate with extremely small cross-sectional size. The characteristics of the point gat...

What are the precautions for mold polishing? Sep 04, 2020
Mold polishing has two purposes; one is to increase the smoothness of the mold, so that the surface of the product from the mold is smooth and beautiful, and the other is to make the mold easy to release, so that the plastic will not be stuck on the mold and cannot be taken off. Mastering a reasonable polishing method can improve the quality and service life of the mold, thereby improving product ...

2.2.3 Side gate The side gate is also called the edge gate, which is generally opened on the parting surface and feeds from the outer side of the cavity (plastic part). The side gate is a typical rectangular cross-section gate, which can easily adjust the shear rate and gate closing time during mold filling, so it is also called a standard gate. The side gate is characterized by simple gate cross-...

.2.5 Fan gate Fan-shaped gate is a gradually expanded gate, which is a variant of side gate, and used to form large-width plate-shaped plastic parts. The gate gradually widens along the feed direction, and the thickness is gradually reduced to the thinnest. The plastic melt is uniformly distributed in the width direction, which can reduce the internal stress of the plastic part and reduce th...
