Injection molding vacuum system

●Introduction
To eliminate gas entrapment, vacuum technology is applied to vacuum after closure the molds. When gas is evacuated, in-mold resistance force is decreased.
GENMAN determines the vacuum system for customers’ base on their molds & injection parts. We offer one-to-one advice to our customers from our professional prospective. With our support, our customers are able to achieve the best possible results.

Advantages
1. Apply vacuum system in order to…
.decrease resistance force in mold cavity for molten flow
.simplify complicated injection settings
.extend the time between mold maintenance shutdowns
.reduce mold maintenance cost
.extend mold service life
.be impressed by improvements of bubbles (vacuum voids), short shots, unequal thickness, jetting marks, weld lines, knit lines, black streaks, strain
 
2. Advantages for your Injection Molding Machine:
.Reduce clamping force
.Reduce injecting pressure
.Stabilize injection pressure controlling & accuracy
.Less overload circumstances thanks to none demand of ACC system
.Reduce repair cost
.Reduce reject rate

Units & Application
Proper selection is based upon a number of variables, thickness and sizes of injection part, fill time, and mold design.
1.Mid-Low Vacuum Level: suitable for mold cavity air/ gas evacuation purpose
2.Medium-High Vacuum Level: suitable for complex & thin injection part (thickness over 0.2mm)
3.High Vacuum Level: suitable for high complex & thin injection part (thickness below 0.2mm)
