Whether the type and specification of the injection molding machine are correct before use will have a greater impact on the production cost, quality and production efficiency of the injection molded products.

Before selecting the specifications of the injection molding machine, first check the performance parameter values ​​of the injection molding machine in the product manual provided by the injection molding machine manufacturer. These parameter values ​​represent the main performance characteristics of the injection molding machine. According to some technical requirements of the plastic products to be produced, such as the types of raw materials for the products, the brand, the weight and the external dimensions of the products. To find the parameter values ​​close to it in the manual, the injection molding machine model corresponding to these parameter values ​​is the injection molding machine to be purchased.

At the same time, we must also understand whether the working accuracy, speed and product accuracy level of the injection molding machine meet the molding conditions of the product.

The key comparison data in the specifications and models include: the proportional relationship between the quality (or volume) and the external dimensions of the injection molded product and the parameter value in the equipment,

that is, the proportional relationship between the manufactured weight and the theoretical injection volume (or volume) of the injection molding machine: product The size requirements of the length (or height) and the sum of the thickness of the forming mold (or the thickness of the mold on the moving template) and the travel distance of the moving template of the injection molding machine.

In addition, it should also be verified that the size of the mold structure to be installed on the injection molding machine conforms to the conditions of the injection molding machine:

1) The distance between the tie bars should be larger than the width and height of the mold to facilitate the assembly of the mold.

2) The size of the template conforms to the size requirements when the molding die is installed and fixed.

3) The width and height of the mold must conform to the minimum mold size recommended by the injection molding machine.
