Is the injection product cracked again? This article teaches you to deal with cracking easily

In our injection molding, due to various factors, we often see some uncomfortable cracking after molding, which often makes us feel headache. So today, let’s talk about how to deal with the cracking of plastic parts.
Cracking includes filamentous cracks, microcracks, white top, surface cracking of parts, or trauma crisis caused by sticking parts and flow channels. According to the different cracking time, cracking can be divided into demoulding cracking and application cracking. There are three main reasons
Processing reason:
(1) If […]

Suggestions on the installation of injection mold

1. Preparation before installation
Confirm the cooling water channel, and the screw depth into the machine plate is 1.5-1.8 times of the screw diameter. If the screw is not enough, it is easy to slide the teeth, and there is a risk of mold falling. Confirm whether the operators, materials, tools, documents, equipment and auxiliary equipment required for production are complete.
2. Method of lifting formwork
When the hanging die is not horizontal, there will be segment difference between the front and […]

Delamination and peeling of injection molding

The causes of delamination and peeling in injection molding products are as follows
Material temperature is too low, injection mold temperature is too low, screw speed is too fast, resulting in internal stress.
The cold material hole is small, the fluidity is poor, and the material is cooled too fast.
The holding pressure is low and the back pressure is too low.
The raw material is mixed with impurities.
Release method:
Increase the material temperature, die temperature, reduce the shear force of melt flow, reduce […]

How to solve the matte surface of plastic injection parts?

Low gloss means that the surface is dark and dull, and the transparency of transparent products is low. There are many reasons for poor gloss. The surface gloss defects of general products can be divided into the following three types: plastic mold failure, improper molding conditions, improper use of raw materials.

Injection mold failure
Because the surface of the plastic part is the reproduction of the surface of the mold cavity of the plastic mold, if the surface of the plastic […]
