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...

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...
Know about Polycarbonate Sep 17, 2019
PC is an amorphous engineering material with exceptional impact strength, thermal stability, gloss, bacterial inhibition, flame retardant properties and stain resistance. The otched Izod impact stregth of the PC is very high, and the shrinkage rate is very low, generally 0.1 to 0.5%. PC has good mechanical properties, but its flow characteristics are poor, so the injection molding process of this ...
The Manufacturing Processes for Plastic Products Sep 27, 2019
The manufacturing process of a plastic article refers to a process of making a final plastic article from a polymer manufactured by a synthetic resin manufacturer. Processing methods include: compression molding, extrusion molding, injection molding, blow molding etc. Detailed manufacturing process: (1) Compression Molding: Molding is also called press molding. It is mainly used for the mold...
Damage of Plastic Products Sep 27, 2019
What is damage of plastic product? and what is caused it? Damage of Plastic Product, means that product parting position or slider closing damaged There are three reasons caused this problem: 1. The angle is not enough, the position and size of the ejection are not enough. 2. Die surface treatment is not good, coating is not smooth, texture too thin or too thick. 3. During injection molding, the s...

What is the delamination of the plastic product? Oct 23, 2019
It means that products delamination like mica sheet, because different material is mixed, especially for different Shrinkage material. There are a few reasons caused this problem: 1. The melt temperature is too low, material couldn't conbine well. It may caused products delamination under ejected acting force. 2. The back presure is too low. 3. The material consistency is not so good. 4. Mat...

Short shot Nov 20, 2019
We are going to talk about one of the most common problem during mould trial--short shot. The factor are as below: 1. It means that the cavity is not completely filled, caused the plastic parts incomplete; 2. The mold venting is not good; 3. The section of gate and runner is too small and long, The melt pressure loses too much during the flow; 4. The thin wall is not thick enough; 5. There is no c...

Short shot Nov 29, 2019
During last articl, We have talked about the factor caused short shot. Today, we are going to talk how to improve it. The improvements are as below: 1. Modify or improve venting structure; 2. Modify or improve gate system; 3. Increase section thickness; 4. Design a suitable cold well; 5. Increase injection speed appropriately; 6. Change the suitable injection machine; 7. Change a large nozzle; 8. ...
