Solution for defects of transparent plastic injection parts Feb 15, 2019
(1) eliminate the interference of gas and other impurities, and fully dry the plastic. (2) reduce the feed temperature, adjust the feed barrel temperature in stages, and appropriately increase the mold temperature. (3) increase the injection pressure and reduce the injection speed. (4) increase or decrease the preplasticized back pressure, reduce the screw speed. (5) improve the exhaust condition ...

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...

Undercut in Plastic Mold Mar 29, 2019
In some plastic products, there are undercuts. If it is a small undercut, and the requirements of shape and size accuracy are low, or the plastic material has sufficient plastic deformation and toughness, the parts can be ejected/ demoulded by force. According to the different structures and requirements of plastic parts, the slider and lifter mechanisms is adopted to solve the problems in m...

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...
