Requirements of Thin-wall Injection Molding to Mold Feb 15, 2019
Speed is one of the key factors for the success of thin-wall injection molding. Rapid filling and high pressure can inject molten thermoplastic material into the mold cavity at high speed, to prevent the gate from freezing. If a standard part fills in two seconds, the mold thickness will be reduced by 25%, and the filling time may be reduced by 50% (saving 1 second in time). When thickness decreas...

What is double injection mold? Mar 02, 2019
Double Injection Mold, also known as two material molding, 2 shot molding or 2K molding, is a manufacturing process used to produce complicated molded parts from two different materials. Two kinds of plastic materials are injected on the same injection machine, and they are formed twice, but the product is only molded out at once. This injection molding is usually completed by one mold and require...

Venting of plastic injection molds Mar 02, 2019
It is well known that the exhaust of injection mold is a problem that cannot be ignored in the mold design.Mold inner product set in the normal production of gas mainly has the following sources: 1. The feed system and the entities of the air in the cavity. 2. The plastic contains moisture evaporation and water vapor generated at high temperature. 3. The gas produced by plastic decomposition. 4. S...

The checking points for mold flash part Apr 12, 2019
It's very common to see some flashes on the part during mold testing. Today we are going to discuss some check points when we get flashed parts. 1. Mold fitting 2. Parting Line (PL) problem (1) Check if the surface of the core is higher than the surface of the AB plate (about 0.5MM) (2) Check the flatness of the surface to see if it is deformed because the mold plate is too thin. (3) Is there any ...

The advantages for Hot Runner Mold Apr 22, 2019
The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today. Shorten cycle The molding cycle is shortened. Because there is no restriction on th...

Preparations Before Mold Trial Apr 26, 2019
Mold trial is an essential part of the new mold before injection production, The quality of the test results will directly affect whether the subsequent production of the factory is smooth. What precautions should be paid attention to when test the mold? 1. Familar with the relevant information of the mold It is better to get the mold drawing, analyze it in detail, and get the mold technician to p...

The program control of injection speed Apr 26, 2019
The program control of the injection speed is to divide the injection stroke of the screw into 3 to 4 stages, and each of the stages uses an appropriate injection speed. For example, when the molten plastic just starts to pass through the gate, the injection speed is slowed down, and during the filling process, high-speed injection is used, and the speed is slowed down at the end of filling. With ...
Four stages in the injection molding process May 20, 2019
Under the action of the screw thrust, the melted material has flowed through the barrel, nozzle, runner, gate, etc. at a certain rate and then injected into the cavity, and the injection pressure is gradually decreased by overcoming the flow resistance. Plastic filling process and molding quality. In addition to the injection pressure, it depends on the melt injection speed, melt and mold temperat...
