What is warpage on the plastic products? Aug 05, 2019
The products uneven shrinkage caused of some factor, this will creates deformation which we call it warpage. It's a quite normal problem on the plastic products, So how can we solve it? 1. Extending holding pressure time; 2. Design a right gate tipe which will loss minimum pressure. 3. Increasing cooling time; 4. Adding mold cooling tube; 5. Changing product structure, such as adding rib, improvin...

Actual Case Analysis of Poor Shrinkage (2) Aug 09, 2019
Today we are continuing to discuss another case for the sink mark, we will show what we would do when we face the sink mark problem. 1. Basic information: ABS Case shrinkage 2. Description: a. Even if the maximum injection pressure is selected for molding, shrinkage will occur in the place where Rib is behind the molded part. b. As shown in picture, the cross-sectional area of the gate...

Injection molding and blow molding Sep 18, 2019
Plastic molding is a process in which a synthetic resin is used to make a final plastic product. Processing methods include: compression molding (molding), extrusion (extrusion), injection molding (injection molding), and blow molding (hollow molding). Let's distinguish between the molding process of injection molding and blow molding. (1) Injection molding: Injection molding is a method in which ...

What is venting defective of product? Aug 19, 2019
When the injection machine starts to molding，the hot melt plastic flows in the mold cavity and squeezes the air in the mold cavity. If the air cannot be discharged effectively, it will cause venting, and the result will be that the product is short-shot or affects the quality. Under this situation, We need to check the injection speed, the mold temperature, Or add venting groove.

Actual Case Analysis of Poor Shrinkage (3) Aug 23, 2019
Today we are continuing to discuss the 3rd case for the sink mark, we will show what we would do when we face the sink mark problem. 1. Basic information: PC combination transparent block, poor shrinkage 2. Description: there is not enough holding pressure time, but it is easy to cause flash by increasing the injection pressure. 3. Improvement: Increase the holding pressure time (with a pressure o...

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, ...

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.
