Four Column Hydraulic Press for SMC BMC Composite Manhole Cover Hot Compression Molding

Description

This composite municipal manhole cover hydraulic press is specially developed for hot compression molding of SMC, BMC and FRP resin composite materials. With rigid four-column frame and stable pressure output, it is widely used for producing municipal manhole covers, drain grates and inspection well lids. It supports adjustable temperature, holding pressure and exhaust time. PLC touch screen control and safety protection devices are equipped. Custom worktable, stroke and matched heating molds are available.

The machine realizes integrated processes of material feeding, mold closing, heating, pressure holding, exhaust and demolding. It can manufacture anti-theft, high-load, corrosion-resistant composite manhole covers, drain covers and channel covers for urban road, municipal drainage, communication and power engineering. The built-in multi-stage pressure adjustment and slow mold opening function effectively prevent cracking and deformation of finished products, greatly improving the yield rate.

It is equipped with PLC + human-machine touch screen control. Operators can set molding pressure, holding time, heating temperature, exhaust frequency and pressing speed freely. Standard configurations include overload protection, emergency stop button and safety grating. Optional accessories include mold temperature controller, automatic feeding device and automatic demolding mechanism.
