Wanrooe manhole cover hydraulic press machine can also press other FRP resin material products. You need to heat the waste plastic for extrusion, then weigh the material into the mould cavity, start the equipment for mould closing, then heat and hold pressure for a few minutes, and then retract the mould. The manhole cover pressing is then completed.
Wanrooe Heavy Industry can design and produce manhole cover hydraulic presses of different tonnages, such as 200 tonnes, 315 tonnes, 400 tonnes, etc., according to customer needs.
Manhole cover hydraulic press machine process:
1. Prepare waste plastic to be heated by extruder.
2. Measure and fill the resin raw material into the mould of the required type.
3. Place the welded steel skeleton into the mould and fix it firmly.
4. Fill the remaining resin material into the mould and spread it evenly.
5. Start the manhole cover moulding hydraulic press to press the product.
6. Products in the mould gradually cure and take shape under high temperature and high pressure from the machine.
7. When the designed holding pressure time is reached, the manhole cover forming hydraulic machine starts to retract. The product is shaped, taken out from the mould, and cooled down.
8. After the product is taken out, clean up the burrs, make it smooth all around, and place it steadily to prevent deformation.
9. After the product has initially cooled, install the required accessories and perform a 1-meter free fall weight test.
Wanrooe produces this manhole cover hydraulic press machine generally using a three-beam four-column structure. The tonnages are not very large, the structure is compact, and it features PLC control. It is applicable to various metal and plastic material stretching and forming. If there are special needs, our company can customize production according to actual requirements.
