Resin composite manhole covers use glass fiber and resin as basic materials, with curing agents, accelerators, etc. as auxiliary materials. A certain amount of pressure is exerted by the FRP manhole cover making machinery and the mold, and forming the resin manhole cover by hot pressing in one step. FRP manhole cover-making machinery is commonly used in four-column structure hydraulic presses such as 315 tons, 400 tons, 500 tons, and 630 tons. The mold uses electric heating, and the heating temperature is mostly 140℃-150℃.
Our FRP manhole cover making machinery consists of a main machine, a hydraulic system, an electrical control system, a pumping station, etc. The main body adopts a three-beam and four-column structure, and the sliding beams are thickened and tempered. It will not deform under high working temperatures. The pressed products are uniform in thickness, strong, and resistant to pressure.
The 500-ton FRP manhole cover-making machinery has added two temperature control modules and is equipped with an independent temperature sensor. It supports real-time digital display and manual setting of temperature. The temperatures of the upper and lower molds are generally set at 140℃~150℃. Setting the temperature too low will affect the material flow efficiency and pressure holding time, and may easily cause product defects. Excessive temperature will “scald” the product, causing the manhole cover and the mold to adhere to each other and prevent smooth demoulding.
The 500-ton FRP manhole cover making machinery also has a shutdown and pressure-maintaining function. The industry’s high-quality seals are used,
