Product Parameters
The PP hollow building board making machine is engineered for construction-grade PP materials, featuring a reinforced screw-barrel assembly (L/D 30:1) with wear-resistant nitriding treatment. Its multi-zone temperature control (160–190°C) ensures full melting of PP granules mixed with glass fiber additives (for enhanced rigidity), while the custom steel mold shapes the hollow formwork structure with ribbed reinforcement, supporting thicknesses 10–25mm and widths up to 1.2m.

Unlike standard extrusion machines, the PP hollow building formwork extrusion machine integrates a unique internal rib-forming system, strengthening the formwork’s load-bearing capacity (up to 50kN/m²). A dual-cooling system—water-cooled calibration sleeve plus air-blow cooling—prevents warping, critical for formworks requiring strict flatness. The servo haul-off unit with anti-slip rollers maintains stable traction, paired with a flying saw for precise length cutting (±3mm) to match construction site needs.

Equipped with a PLC touchscreen, it enables real-time adjustment of extrusion speed, mold temperature, and cutting length. Compared to Polypropylene hollow building board extrusion equipment for general panels, it emphasizes structural integrity and reusability (up to 50 times). With output rates 150–500 kg/h, it supports recycled PP (30–50%) and meets construction standards (e.g., GB/T 38057). Its low-energy design and easy mold changeover make it a cost-effective, eco-friendly solution for modern construction formwork production.

FAQ

1. What is the energy consumption during equipment operation?

Our equipment uses energy-saving motors and heating systems, resulting in energy consumption 8%-12% lower than conventional equipment in the industry (for example, a PVC foam board line consumes approximately 50-80 kWh per hour, depending on production capacity). If your existing equipment consumes high energy, you can contact us for upgrade solutions (such as replacing energy-saving motors and optimizing temperature control systems) to help reduce long-term operating costs.

 

2. Can the equipment be adapted to different raw materials?

For example, what adjustments are required when switching from PVC to PP?

Some equipment supports multiple raw materials (this must be specified in the customization proposal). When switching from PVC to PP, screw speed, heating temperature, and mold parameters must be adjusted. Our engineers will provide detailed adjustment guides. If core components need to be replaced (such as screws adapted for different raw materials), we can provide genuine spare parts and replacement services to ensure normal operation of the equipment after the switch.

 

3. How long does it take from ordering to delivery of the equipment?

The delivery time for standard equipment (such as small plastic pipe production lines) is approximately 30-45 days. Customized production lines (such as large PVC building formwork production lines) are approximately 45-60 days, depending on the complexity of the solution. Regarding overseas logistics, sea freight to near-sea markets (such as Southeast Asia) takes approximately 7-15 days, while sea freight to ocean markets (such as the Americas and Africa) takes approximately 25-40 days. We will track the logistics progress throughout the entire process to ensure timely delivery.
