How to prevent the injection mold deformation during use

Color die in the course, will inevitably produce deformation phenomenon, now by the Dongguan City Rongsheng Industrial Co., sorting out the situation can prevent deformation of the injection mold.
First, at the time of injection molding plastic products, by the high cavity injection force by the elastic material becomes caught in excessive plastic products, plastic products led to difficult out.

Second, the relatively soft material injection mold, injection molding machines, plastic injection mold cavity will produce high pressure, resulting in deformation of the mold volume expansion. If the injection pressure is relieved not to make injection molds restored to their original, it will cause mold damage.

Third, in order to avoid double injection mold deformation caused production losses, we should take active measures to prevent it.
1, the special shape of the plastic products, such as cup-type products, injection mold design spout should special treatment.
2, if the injection of plastic products is complex, core-pulling or mosaic, the need to ensure manufacturing precision Plastic mold and mold temperature balance control when injected.
3, two-color mold at the time of manufacture, should be repeated to test its ability to bite, later improved heat treatment process, improve the mold hardness, reduce the amount of work generated by the deformation.
4, two-color injection mold punch if the temperature is too high, will lead to expansion of the volume of plastic products, injection molding die in the article is not easy to come up, it is generally convex mold temperature regulators are set to control the entire mold temperature constant.
5, in order to effectively avoid due to injection mold cavity pressure caused by deformation can be fitted above the mold pressure sensor monitoring the pressure side changes, if beyond the safe range, can adjust the injection pressure and other parameters, to ensure the normal operation of the mold.
By implementing the above preventive measures, in practice the strict production requirements, will be able to prolong the life of the injection mold, injection mold reduce repair times and improve company efficiency.
