1、 Shrinkage
The first thing to pay attention to during production is to pay attention to the processing shrinkage of materials, because in the production process of injection mold, plastic raw materials need to be heated to become liquid before subsequent processing. Therefore, the volume of raw materials in different cold and hot states will also change to some extent. In this production process, Precision mold processing technology must ensure that the shrinkage is within the control range in order to accurately produce high-quality injection molds
2、 Liquidity
The heated plastic raw materials have fluidity, especially the strength of fluidity, which will also change with the difference of temperature and raw material ratio. Therefore, in the process of producing injection mold, we must also pay attention to the fluidity of raw materials. Sometimes the fluidity of raw materials is stronger, and sometimes the fluidity is weaker, Therefore, we must also pay attention to the precision mold processing technology in the production process of injection mold, and can effectively control the fluidity of plastic by using additives and controlling temperature, so as to ensure better production efficiency and better production results in the production process< br> 3、 Crystallinity
The raw materials of injection molds usually have a certain crystallinity, but the crystallinity will also produce different phenomena for the quality of products, so they can be divided into crystalline plastics and non crystalline plastics. In the production process of injection mold, we must pay attention to the selection of raw materials and select more appropriate raw materials to ensure better products after production< br> 4、 Thermal sensitivity
Some plastics are sensitive to heat, so if they are exposed to high temperature for a long time, they are prone to the risk of cleaning, too small or discoloration, or even degradation. Therefore, when reproducing injection molds of such heat sensitive plastics, special attention must be paid to the processing technology of precision molds, In order to ensure that the products produced by them have high quality when producing such heat sensitive materials
5、 Additives
In the process of plastic processing and production, certain additives must be added to better shape the plastic and enhance the performance. Therefore, special attention should be paid to the use of these additives, the selection of additives and the dosage of additives in the whole production process of injection mold.
