injection machine purchasing attention appointments (2)

The correct selection of the type and specifications of the máquina inyección before use has a greater impact on the production cost, quality and production efficiency of injection molded products.

Before selecting the specifications and models of the injection molding machine, first check the performance parameter values ​​of the injection molding machine in the product instruction 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 type and brand of raw materials used in the product, the quality (peso) and the external dimensions of the product, etc.] to find the similarity in the manual

The parameter value of the parameter value, the injection molding machine model corresponding to these parameter values ​​is the injection molding machine to be purchased.

In wéet k'iin, we must also 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.

1. The key comparison data in the specifications and models include: the proportional relationship between the quality (or volume) and external dimensions of the injection molded product and the parameter value in the equipment, U k'áat u ya'al, the relationship between the quality (peso) and the theoretical injection volume (or volume) of the injection molding machine.

The proportional relationship: the size requirement between the sum of the product length (Ka'anilo') and the thickness of the forming mold (the thickness of the mold on the movable template) and the stroke distance of the movable template of the injection molding machine. Beey xan, 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 greater 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 minimum mold size recommended by the injection molding machine.
2 Classification of injection molding machines
(1) Classified by plasticization method
1. Plunger type plastic injection molding machine
It has poor mixing properties and poor plasticization properties, so a shunt shuttle device must be installed. It is rarely used now.
2. Reciprocating screw type plastic injection molding machine;
Relying on the screw for plasticization and injection, the mixing and plasticizing properties are very good, and it is used most now.
3. Screw-the plunger type plastic injection molding machine relies on the screw for plasticization and the plunger for injection, the two processes are separated.
