The design of plastic injection molds is a crucial aspect in the field of plastic processing, taking into account various factors that need to be comprehensively considered to ensure optimal results. In the design process of plastic injection molds, various factors need to be comprehensively considered, including product shrinkage rate, injection time, determination of cooling or heating forms, and arrangement of cooling channels. In addition, it is necessary to consider the lifespan of the mold, determine the hardness, thickness, and size of the mold material, as well as the difficulty of processing, and determine the disassembly method and wire cutting structure shape of the formed parts.

In the context of fierce competition in the plastic mold industry, the cost of molds and injection molding processing has become a highly concerned topic for every business. In order to reduce costs and create high efficiency, plastic injection mold manufacturers must deeply consider how to achieve this goal in the design process. In the design of plastic injection molds, the following key factors need to be considered:

1. Injection molding cost is an important consideration factor.

Determine the cost of each beer based on the size of the machine, and then determine the product’s ranking and number of holes. Generally speaking, the more molds produced, the lower the injection molding cost, as cost accounting is calculated based on the number of times the mold is produced.

2. The appearance of the product is also a key factor to consider.

According to the product appearance requirements, determine the position of the parting surface to ensure that it is conducive to mold processing, exhaust, and demolding. The impact of appearance issues on product quality and appearance cannot be ignored, therefore it needs to be carefully considered.

3.The choice of water outlet method is also crucial.

Determine the shape, size, and exhaust orientation of the main and branch channels. The cost of hot runner molds is relatively high, but it can save on the cost of water outlets. Different methods have their own advantages and disadvantages, and it is necessary to weigh and choose according to the specific situation.

4. The demolding method of the product also needs to be carefully considered.

Determine the ejection method and the arrangement of the ejector pin position. Increasing the ejection position will lead to an increase in mold costs. In addition, it is also necessary to consider the shrinkage rate of the product, injection molding time, as well as the determination of cooling or heating forms and the arrangement of cooling channels. At the same time, factors such as mold lifespan, hardness, thickness, and size of mold materials, as well as processing difficulty, must also be comprehensively considered.
