PVC Semi-Crust Foam Board Machine

The PVC Semi-Celuka Foam Board Extrusion Machine is a specialized plastic extrusion system developed for manufacturing semi-skin PVC foam boards that combine a reinforced surface layer with a lightweight internal foam structure. This type of board features moderate surface hardness, balanced density distribution, and good mechanical strength, making it suitable for furniture panels, decorative boards, wall cladding, advertising substrates, and interior construction materials. Semi-celuka foam boards bridge the gap between free foam and full celuka boards, offering improved surface quality while maintaining cost efficiency, which is why this extrusion solution is widely adopted in developing markets.

The extrusion system is composed of a PVC twin-screw extruder designed for foaming applications, an automatic feeding and material dosing unit, a semi-celuka foaming mold, a vacuum calibration and cooling table, a haul-off system with synchronized speed control, and a precision cutting unit. The extruder ensures uniform plasticization and stable melt pressure, while the semi-celuka mold controls surface skin formation. The downstream calibration and cooling modules maintain board flatness and dimensional accuracy, forming a complete PVC semi-celuka foam board production line for continuous operation.

This extrusion machine is designed to solve common production challenges such as unstable surface quality, uneven foaming, and high raw material consumption. By optimizing screw geometry and temperature control, the extrusion system achieves stable melt flow and controlled foaming behavior, resulting in boards with smooth surfaces and consistent density. Compared with conventional foam board equipment, the semi-celuka structure improves surface strength while reducing material cost compared to full celuka boards. This balance allows manufacturers to expand application ranges, reduce rejection rates, and improve overall production efficiency.

We provide OEM and ODM customization services, including machine appearance color customization, co-extrusion structure design, online lamination compatibility, and output capacity adjustment based on customer requirements. Our engineering team supports complete extrusion line planning, factory layout design, and utility configuration recommendations. For international customers, we offer overseas installation and commissioning, English operation manuals, operator training, and online remote technical support to ensure stable long-term operation.
