What is the difference between TPU extrusion and injection molding? Aug 05, 2019
Extrusion, also known as extrusion molding or extrusion, is also called extrusion in rubber processing. It refers to a processing method in which the material passes through the action between the barrel and the screw of the extruder, is plasticized while being pushed forward by the screw, and continuously passes through the machine head to make various cross-section products or semi-products. Inj...
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...

Annealing of plastic products Aug 09, 2019
The annealing treatment of plastic products refers to the plasticization unevenness of the plastic in the cylinder or the uneven cooling rate of the product in the cavity, which causes the internal stress of the product to cause deformation, cracking and aging of the product in the future. The annealing treatment is carried out indoors, using a hot liquid medium such as hot water, hot minera...

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.

Analysis of the causes of unstable size of injection molded products -1 Aug 23, 2019
The dimensional change of plastic parts is essentially caused by the different shrinkage of plastics. Any change in material temperature, mold, pressure, and production cycle will lead to changes in the size of the part, especially PP, PE, nylon, etc. with higher crystallinity. The main reasons are as follows: 1. Machine side: (1) If the plasticizing capacity is insufficient, a machine with a larg...

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, ...
