Analysis of plastic mold processing encountered in the influencing factors

The introduction of plastic mold quotes generally include the cost of raw materials, design costs required for the design of the product, the processing costs required to process the mold, the product needs to pay the value-added tax, tryout the required trial mold costs, product packaging and transportation required Package shipping costs.


1, then the task book, by the product designer or design team to provide the necessary tasks to produce products. After review on the drawings mark the data required everywhere and precautions.

2, analysis of plastic mold processing encountered in the influencing factors. Determine the cavity surface and parting surface involved in the plastic mold processing, select the most appropriate way to set out, pay attention to the temperature control and parts forming the structure involved in the process, pay attention to the calculation formula.

3, the plastic mold information collection, collation, analysis, understand the specific steps of each specific production steps, familiar with the product's work

Injection process can be broadly divided into three steps, first, temperature control; second, pressure control; third, molding cycle. Temperature control is divided into barrel temperature control, nozzle temperature control, mold temperature control. Different plastics have different flow temperatures, so choose the barrel temperature for each plastic. The nozzle temperature is usually lower than the cylinder temperature, the nozzle temperature will affect the performance of the product after molding. The mold temperature on the performance and quality of products also have a great impact on mold temperature control based on crystallinity, mold size and structure and other external conditions and internal conditions.
