  • Description
Introduction of product features

-Saving energy
The electric melt adhesive injection molding machine screw is directly driven by a separate servo motor through a reducer, which has no double volumetric efficiency loss of oil pump and motor oil and pressure loss of hydraulic pipeline, and save energy in a 15% ~ 25% compared to servo hydraulic melting adhesive system.
-Synchronization
It can realize synchronous melting adhesive by opening the mold and shortening the product formation cycle (need a needle valve hot runner mold match).
-Convenience
The screw is driven directly by servo motor, which has low inertia, quick response and agile process adjustment.
-Stability
Without the influence of hydraulic pulsation, the screw speed is stable and the melt adhesive measurement is accurate, which is beneficial to the formation of transparent and accurate products;
-Environmental Protection
Electric melt adhesive has high work efficiency, low power consumption and can save cooling water. There is no influence of hydraulic impact, and the noise value is lower.
