How to select injection molding machine? Generally speaking, before selecting the specification and model of the injection molding machine, first check the performance parameter values of the injection molding machine in the product instruction provided by the manufacturer of the injection molding machine. 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 variety and trademark of the materials used for the products, the quality (weight) and shape standards of the products, etc. Find the parameter values in the instruction book that are close to them. The model of the injection molding machine corresponding to these parameter values is the injection molding machine to be purchased. At the same time, we should also know whether the operation precision, speed and product precision of the proposed injection molding machine are equal to each other, and whether they meet the molding conditions of products.

Also, the key comparison data in the specifications and models are: the proportional relationship between the quality (or volume) and shape standard of the injection molding products and the parameter values in the equipment, that is, the proportional relationship between the manufacturing quality (weight) and the theoretical injection volume (or volume) of the injection molding machine: the product length (height) standard and the thickness of the molding mold (the mold thickness on the moving template) Standard requirements between the sum of the standards and the travel interval of the moving template of the injection molding machine. In addition, it should also be verified that the mold structure standard of the equipment to be installed on the injection molding machine is consistent with the conditions of the injection molding machine:

The spacing standard of the pull rod shall be greater than the width and height standard of the mold to facilitate the installation of the mold; The standard of the formwork shall meet the standard requirements when the molding die equipment is fixed; The width and height of the mold must conform to the small mold standard recommended by the injection molding machine.

The above is how to select injection molding machines. If you want to know more professional knowledge, you can consult professional books!
