The composite resin manhole cover is divided into the SMC resin manhole cover and BMC resin manhole cover according to the raw material structure, after the hydraulic and mold quickly mold can be formed once. It is generally use 315T four-column press machine according to the size of the manhole cover and the required pressure.
315T resin composite hot press hydraulic press uses hydraulic cylinder to generate pressure, and there is a plate in the hydraulic press, the workpiece is processed on the plate. The following is the working principle and advantage of the hydraulic press.
Working principle
The 315T resin composite material hot molding hydraulic press operates according to the principle of Paska, which provides that when the pressure is applied to the restricted fluid, the pressure change occurs throughout the fluid. In the hydraulic press, there is a piston to work as a pump, providing a moderate mechanical force for a small range of workpieces. There is also a larger piston that produces greater mechanical forces.
Advantage:
The use of hydraulic press has greatly improved the speed of producing and making of company products. It’s obviously in the , wherein the inter-process switching is significant, and it can be produced by more than a polyprotogenic production.
