Injection Molding: Understanding Pressure Loss In

2011-1-4 · The machine reports a hydraulic pressure at transfer of 2040 psi (hydraulic), and the part is 96% full and short. To find the plastic pressure in the nozzle, you need to multiply 2040 psi × the intensification ratio of the machine, which in this case is 14.7:1.

Injection Speed - an overview | ScienceDirect Topics

Injection pressure should also be as low as possible. Dimensional stability improves when pressure is lowered because of a reduction in the residual stresses in the molded part. Injection pressure may have to be increased if an improvement in the weld line or a reduction in sink marks is desired. Part design and equipment capability should

Back Pressure Control of Injection Molding Machine

2018-9-19 · Problems with too low back pressure. 1. When the back pressure is too low, the screw retreats too fast, and the density of the melt flowing into the front end of the barrel is small (relatively loose), and more air is trapped. 2. will lead to poor

Difference between Low Pressure Injection Molding And

Temperatures for Low Pressure Injection Molding is low, cast aluminum mold can be used. Compared to steel mold, aluminum mold is better for design and development. And the development cycle of the mold is shorter. Also, compared to traditional high-pressure injection mold, low-pressure hot melt adhesive injection molding process cycle is shorter.
