Causes of color defects in injection parts Feb 15, 2019
(1) poor mold finish, mold surface rust, mold exhaust is bad. (2) if the casting system of the mold has defects, the cold feed well should be increased, and the flow passage, polishing mainstream passage, diversion passage and gate should be increased. (3) the material temperature and mold temperature are low, if necessary, local heating method of gate can be used. (4) low processing pressure, slo...

Why does the domestic mold industry have been fighting the price war? Mar 15, 2019
Why the domestic mold industry has been playing the price war? At present, there are many china tool manufacturer engaged in mold production at home, but the scale is relatively small, the basic model is small workshop, most is cheap mould, and the content of science and technology is very low. Small mold enterprises produce products are basically imitation, resulting in more and...

What is Ejector Marks? Apr 12, 2019
Ejector mark is the phenomenon of stress whitening and stress elevation where appears on the opposite side of the nozzle facing the product, or where the ejector rod is located on the ejecting side of the tool. Why will it cause the ejector marks? The physical reason is when the demoulding force is too high or the surface of the ejector rod is relatively small, the surface pressure will be very hi...

Injection Mold Cooling Water Leakage Failure and Troubleshooting Apr 22, 2019
Injection mold cooling water leakage is a frequent occurrence, for many reasons, mainly in the following aspects: 1. The most occurs at the joint of the mold cooling water pipe. If water leakage is found, the sealing tape should be wound around the thread of the pipe joint and then tightened. 2. Due to long-term molding conditions, the waterproof ring inside the mold will be damaged, and the O-sha...
Cooling System in Injection Molding (1) Apr 26, 2019
The design of cooling system is very important in injection moulding. This is because only when the plastic parts are cooled and solidified to a certain hardness, can the plastic parts be avoided from deformation due to external force after demoulding. Because the cooling time accounts for about 70% - 80% of the whole cycling time in moulding, a well-designed cooling system can greatly short...

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 ...
