How to choose an injection molding machine correctly

Before we select the specifications and models of the injection molding machine, we must first check the performance parameter values of the injection molding machine in the product manual provided by the injection molding machine manufacturer. And 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 type and brand of raw materials used in the product, the quality (weight) of the product, and the size of the product.

Go to find the parameter values in the manual that are close to it. The injection molding machine model corresponding to these parameter values is the injection molding machine to be purchased. At the same time, it is necessary to know whether the working accuracy, speed and product accuracy level of the injection molding machine to be purchased meet the molding conditions of the product.
In addition, the comparison data in the specifications and models are: the ratio of the quality (or volume) and external dimensions of the injection molded product to the parameter value in the equipment, that is, the ratio between the quality (weight) and the theoretical injection volume (or volume) of the injection molding machine. The proportional relationship between.
The length (height) of the product and the thickness of the forming mold (thickness of the mold on the movable template) are required to be between the sum of the dimensions and the stroke distance of the movable template of the injection molding machine. In addition, it should be verified that the structural dimensions of the mold to be installed on the injection molding machine are consistent with the conditions of the injection molding machine:

1. The distance between 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 size requirements of the molding die when it is installed and fixed.

3. The width and height of the mold must meet the smaller mold size recommended by the injection molding machine.
