plastic blow molding machine producing products are designed according to the requirements of use. In the design, we must first consider the full advantages of plastic material performance, to avoid shortcomings, to meet the requirements of the use of the premise, the shape and structure of plastic blow molding machine producing products should be to simplify the mold structure as much as possible, and meet the process characteristics.
To sum up,Silver Python Machinery consider the following seven factors.
1.plastic blow molding machine producing products material physical and mechanical properties, such as strength, rigidity, toughness and so on.
2.plastic blow molding machine producing products material molding process, such as mobility (melt flow rate, viscosity)
3.plastic blow molding machine producing products material health performance, such as whether the food packaging, pharmaceutical packaging requirements.
4.plastic blow molding shape should be conducive to filling the mold flow, exhaust, feeding, while adapting to efficient cooling stereotypes.
5.The difference of shrinkage of plastic extrusion blow molding
6.overall mold structure, especially the complex process of the clamping device and Plastic mold release .
7.Structure Design and Manufacturing Technology of Mold Parts.
The above 1-5 is about the performance characteristics of plastic material. 6-7 is about the structural characteristics of the mold. This is the main content that should be considered when designing plastic blow molding.
There are many kinds of plastic used for plastic blow molding, but from the point of Silver Python machinery,in view of molding, not all plastics can be used for blow molding, suitable for blow molding commonly used plastic mainly in the following
PE/PP/ PVC/ PS /PAN /POM/ ABS/ PA /PC /PET/ PPS /PVDC /PVDP/ PPO
