Injection mold injection processing technology

1. The barrel temperature is too high or the injection volume is too much. When the mold temperature is too high, the molten material in the cavity is not cooled in place, and the volume is not restored to the preset size, which causes the situation that the mold cannot be removed;

2. The injection pressure is too high or the pressure holding and cooling time are too long. Injection temperature includes barrel temperature, nozzle temperature, etc. If the temperature is too high, the melt enters the cavity and cannot be cooled for a predetermined time, which also affects the demolding effect;

3. Excessive injection volume. The injection volume exceeds the cavity capacity, which is what we often say is the expansion of the mold. When the pressure is released, the injection of too much melt will expand, so that the expansion cannot be removed from the mold. Adjust the injection volume to solve it;

4. Improper injection cycle. If the injection pressure is too high, the holding time or the cooling time is too long during injection molding, it will also cause the hidden danger of difficult demolding. The completely cooled product is also not conducive to demolding. The injection cycle must be appropriate.

In terms of raw materials: insufficient lubricant.

The traditional demoulding methods of plastic molded parts are roughly divided into four types: pushing, pushing, pulling, and spinning.

Now there is a newest demoulding technology that can easily solve the problem of plastic demoulding. In the plastic mold industry, there are many unsolvable problems, especially when a variety of resin compounds are used for highly complex designs and high-gloss finish processing.

Nano release coating can form a coating on the surface of the plastic mold, or even on the surface of the plug-in of the plastic mold, which can significantly reduce the friction coefficient of these surfaces. A high gloss processing surface can be achieved without the use of traditional mold release agents. The design and plastic compound used make the machine/tool maintenance downtime for a long time, resulting in low production yield and economically unfeasible critical conditions. Nano-release coating can also extend the uninterrupted production time and significantly reduce the machine/tool Maintain the downtime. Maximize the efficiency and role of plastic mold production and reduce waste. Nano release coating not only improves the smoothness and accuracy of the plastic mold surface, but also greatly improves the productivity of the plastic mold manufacturing industry!
