Production Process Flow of HDPE Drainage Sheet Machine:
1. Raw material preparation， Use HDPE granular materials, both brand-new and recycled materials are acceptable.
2. Extrusion molding， The raw materials are melted and extruded through a screw extruder to form the initial shape of the sheet.
3. Vacuum forming， By using concave-convex rollers for vacuum forming, the sheet material is given specific shapes, such as conical, columnar, and spherical shells.
4. Cooling and shaping， By using methods such as circulating water cooling, the sheet is rapidly cooled and shaped.
5. Traction cutting，Through the traction device, the drainage board is cut to the set length to obtain the finished product.
