What is the different between plastic mould and plastic injection mould? Sep 09, 2019
Plastic mould include injection mould, plastic injection mould is one of plastic mould. Plastic mould is a joint name of compression mould, extrusion mould, injection mould, blow mould and foaming mould. Plastic mould is a tool to manufacture plastic products, it could make plastic products to be more complete and the size more accurate.

What is the push rod demoulding ? Sep 02, 2019
During the production of injection, some products are not easy to demould. Therefore, there is a push-rod release mechanism at the time of mold design. The push rod demoulding device is simple structure, convenient manufacture and replacement, small sliding resistance and flexible demoulding position, and is the most commonly used structural form in the demolding mechanism. Howev...

The main point of selecting the screw for nylon PA in injection molding Sep 09, 2019
The main point of selecting the screw for nylon PA injection molding: PA is a crystalline plastic with many types and different melting points. Generally, PA66 has a melting point of 260~265 °C. The material has low viscosity, good fluidity, relatively obvious melting point, poor thermal stability and general water absorption. When using PA material for injection molding, the following points shou...
Plastic injection product defects discussion Sep 18, 2019
Today we are going to discuss common defects for plastic injection products. 1. Short shot The plastic part is insufficiently filled (or the injection pressure is not enough, the mold nozzle is too small). 2. Ejector Mark The part is poorly released or the ejector pressure is too high. White marks and bumps appear on the surface of the product: 3. Flow marks: The Part is not slippery, ...

Analysis of the causes of unstable size of injection molded products -2 Sep 10, 2019
Plastics: (1) The mixing of new materials and recycled materials should be consistent. (2) The drying conditions should be consistent and the particles should be uniform. (3) The influence of shrinkage rate on dimensional accuracy is fully considered when selecting materials. 4. Processing: (1) If the plastic processing temperature is too low, the temperature should be increased because the ...

Splay Mark of Plastic Products Sep 17, 2019
Splay mark is a normal problem during manufacture plastic products. There are a few reason cause this problem: 1. The material contains water, drying time is insufficient. 2. Weld back pressure is too small or no back pressure. 3. Venting is not so good. We need keep to drying the material, Increasing back pressure, Improving the mould venting.

Analysis of the Causes of the Shock Pattern of Injection Molding Products Sep 23, 2019
Rigid plastic parts such as PS form a dense corrugation on the surface near the gate, centered on the gate, sometimes called a shock pattern. The reason is that when the melt viscosity is too large and the mold is filled in a stagnant form, the front end material quickly condenses and shrinks as soon as it contacts the surface of the cavity, and the subsequent melt expands the contracted cold mate...

Actual Case Analysis of Poor Shrinkage (4) Sep 23, 2019
1. Basic information: PMMA Case, shrinkage 2. Description: Using a injection machine with a clamping force of 70 tons (screw diameter of 32 mm, maximum injection amount of 115 g: GP-PS), whether a molded part with a weight of 179.6 g and a thickness of 17 mm can be molded is tested. do. The main problems are as follows: (1) The amount of injection is not enough. In order to solve this problem, we ...
