Elements of the injection molding process (1)

1. Temperature
A. Oil temperature: For the hydraulic machine, it is the thermal energy generated by the friction of the hydraulic oil during the non-stop operation of the machine. It is controlled by the cooling water. When the machine is turned on, make sure that the oil temperature is around 45 ° C. Or too low will affect the transmission of pressure.

B. Material temperature: the barrel temperature. This temperature should be set according to the shape and function of materials and products. If there is a file, set it according to the file.

C. Mold temperature: This temperature is also an important parameter. Its level has a great impact on the performance of the product, so the function and structure of the product must be considered when setting, and the material and cycle must also be considered.

2. Speed
A. Speed ​​setting of mold opening and closing. The setting of mold opening and closing is generally based on the principle of slow-fast-slow. This setting mainly considers the machine, mold and cycle.

B. Ejection setting: It can be set according to the structure of the product. It is best to use a slow ejection speed for some complex structures, and then use a quick demold to shorten the cycle.

C. Fire rate: Set according to the size and structure of the product. If the structure is complicated and the wall is thin, it can be set quickly. If the structure is simple, the wall thickness can be set slowly.
