Advantages of using small gate for injection molding-2 Jul 23, 2020
③Because the small gate has a small volume and fast freezing, when producing certain products, it is not necessary to wait for the entire solidification of the product after the small gate is frozen. As long as the external cured layer has sufficient strength and rigidity, the product can be demolded, thereby Shorten the molding cycle and improve production efficiency. ④In the multi-cavity unbalan...

Main points related to the design of gear mold Jul 23, 2020
1. Gate: generally, 3-point or 6-point is used for balance. For micro gears, usually single point is used. 2. Mold cavity: usually for 1~4 cavities. Small gear can reach 6 or 8 cavities; Different shapes of gears could be 3 cavities. The most representative is 4 cavities. 3. Ejection: normally use center ejector sleeve and ejector pin. For the helical gear, a bearing must be added to assist the ej...

What is thin-wall injection Jul 23, 2020
Thin-wall injection molding technology is also called thin-wall plastic injection molding technology. There are three types of definitions: The ratio of flow length to thickness L/T, that is, the injection ratio of the flow length L from the melt into the mold to the farthest cavity of the cavity that the melt must be filled with the corresponding average wall thickness T is 100 or 150 is thin-wal...

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...

Injection mold gate type and selection-2 Aug 14, 2020
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...

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-...
