Function and characteristics of Micro Foam Injection Molding

Micro foam injection molding The main feature of the molded products is to reduce the weight on the basis of maintaining the original mechanical properties of the products. At the same time, because there is almost no residual stress in the product, the warpage and deformation of the product can be well restrained. Moreover, because it can effectively prevent shrinkage marks, the requirement of wall thickness uniformity of products is greatly reduced, thus providing more space for product design.

In theory, almost all non structural plastic products and some structural plastic products can be prepared by micro foam injection molding process. At present, the demand of injection molding products, such as syringes, medical electrical appliances, injection molding machine, automobile, etc., are mainly developed in the fields of injection molding materials, medical electrical appliances, automobile, automobile and so on.

Micro foam injection molding and its characteristics:

1、 The cycle time of microcellular foam injection molding can be reduced by 50%, thus reducing the processing cost. At the same time, the proportion of leftovers of injection molding products is reduced, and the energy consumption of equipment is also lower.

2、 For the same type of products, the micro foam injection molding process can use smaller and fewer machines, and the mold cost is lower, thus reducing the investment cost.

3、 Because of the low density of the micro foam injection molding products, the products with more thin-walled structure can be designed to reduce the material cost of the products.

4、 Due to the reduction or elimination of the in mold stress in the process of mold closing and packing, microcellular injection molding can produce more flat, straighter and higher dimensional precision products, thus providing more space for the improvement of product quality and price.
