how to select injection molding machine?

TIME:2020-11-24 Share

The injection molding machine is the most used processing machine in the plastics processing industry. Not only a large number of products can be directly produced by the injection molding machine, but also the key equipment that constitutes the injection stretch blowing process.

Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding dies.
The correct choice of the type and specification of the injection molding machine before use, has a greater impact on the production cost, quality and production efficiency of injection molded products. Before selecting the specifications of the injection molding machine, first check the performance parameters of the injection molding machine in the product manual provided by the manufacturer of the injection molding machine. These parameter values ​​are the main performance characteristics of the injection molding machine. According to some technical requirements of the plastic products to be produced [such as the type of raw materials used in the products, the grades, the quality (weight) of the products and the external dimensions, etc.] The parameter values ​​of the injection molding machine corresponding to these parameter values ​​are the injection molding machines to be purchased. At the same time, we must also understand the working precision, speed and product accuracy level of the injection molding machine to be purchased, and whether it meets the molding conditions of the product.

The key data in the specification model include: the ratio of the mass (or volume) and the external dimensions of the injection molded product to the parameter values ​​in the equipment, that is, the ratio between the mass (weight) of the product and the theoretical injection volume (or volume) of the injection molding machine. Relationship: The dimensional requirements between the length (height) dimension of the article and the dimension of the thickness of the forming die (the thickness of the die on the moving die plate) and the distance traveled by the moving die of the injection molding machine. In addition, it should be verified that the size of the mold to be installed on the injection molding machine is consistent with the conditions of the injection molding machine:

1) The spacing of the tie rods should be larger than the width and height of the mold to facilitate the assembly of the mold.
2) The size of the template meets the dimensional requirements when the molding die is installed and fixed.
3) The width and height dimensions of the mold must conform to the minimum mold size recommended by the injection molding machine.
