PP Hollow Sheet Extrusion Machine
for Construction Formwork (Coppha)
JM Machinery specializes in supplying advanced PP hollow sheet extrusion lines designed for manufacturing plastic formwork (coppha) panels used in construction scaffolding and concrete casting. Our systems are engineered for high output, ease of operation, and continuous 24-hour production. The resulting PP formwork panels are durable, reusable, and environmentally friendly.
Features & Applications of the PP Formwork Extrusion Line
Drawing from years of experience and integrating cutting-edge international extrusion technology, JM Machinery has developed a high-capacity, high-quality PP sheet extrusion line tailored for construction needs.
- Panel Specifications: The extrusion line produces PP hollow sheets with a thickness of 12–15mm and customizable widths from 915mm to 1220mm based on customer requirements.
- Product Characteristics: The panels feature smooth surfaces, precise dimensions, and can be processed like wood—sawed, nailed, or planed. They offer excellent corrosion resistance and fire retardance.
Machine Configuration
The production line consists of:
- Single-screw extruder
- Hydraulic screen changer
- Metering pump
- Die head and calibration unit
- First haul-off unit
- Cooling bracket
- Second haul-off unit
- Cross-cutting unit
- Stacking and conveying system
Technical Advantages
- Degassing Screw Design: The extruder’s vented screw design allows moisture to be effectively removed during plasticization, even if the raw material contains higher water content, ensuring excellent surface finish.
- High Efficiency Molding: With innovative mold and calibration system upgrades, our machines can produce two 915mm-wide panels simultaneously with clean-cut edges and stable performance, significantly increasing productivity.
- Dust-Free Cutting Solution: We have redesigned the traditional cutting and dust collection systems to prevent dust leakage—especially important when cutting hollow-core sheets.
Why Choose PP Formwork Sheets Over Traditional Wood Panels?
- Water Resistance: No deformation or deterioration even when submerged for long periods.
- Non-stick with Cement: Cement does not adhere to the surface, allowing easy removal post-casting.
- Smooth Finish: Construction surfaces are smooth and flat, reducing the need for additional surface treatment.
- Simplified Workflow: Fewer steps, faster processing, and the option for pre-treatment to add patterns or textures.
- Lightweight & Easy to Install: Reduces labor intensity and simplifies construction handling.
- Long Lifespan & Recyclability: Panels are reusable many times. Damaged sheets can be crushed and remanufactured, promoting sustainable production.
- Moisture Retention: Helps shorten construction cycles.
- Flexible On-site Processing: Can be cut, drilled, or welded using traditional woodworking tools.
Application Industries
- Transportation: Interior panels for ships, airplanes, buses, and trains.
- Construction & Interior Design: Wall panels, partitions, ceilings, kitchen boards, and decorative shelving.
- Advertising: Signboards, exhibition displays, and digital engraving panels.
- Industrial Use: Corrosion-resistant panels for chemical facilities, cold storage, and thermal insulation projects.
- Others: Molds, sports gear, livestock tools, anti-flood devices, water-resistant structures, and DIY partitions.
