In the high-output environment of a B2B manufacturing facility, the structural integrity of an SPC flooring extrusion line is defined by its ability to withstand extreme thermal stress. Stone Plastic Composite (SPC) production requires the fusion of limestone powder and polyvinyl chloride at temperatures typically ranging between 180°C and 210°C. Without high-level heat resistance standards for machine components, industrial operations face frequent downtime, material degradation, and safety risks.
Critical High-Temperature Components
The most vital area of any SPC flooring production machine is the extrusion barrel and screw assembly. These components are subjected to intense friction and heat. To maintain precision, they must be manufactured from specialized alloy steels (such as 38CrMoAlA) and undergo nitriding treatments. This ensures the surface hardness remains stable even when processed materials reach their melting points.
Secondary to the screw is the T-Die system. The die must maintain absolute thermal uniformity across its entire width—often up to 1200mm or more. Any fluctuation in temperature within the die body can lead to “internal stress” in the flooring, causing the boards to warp after they leave the cooling stage. Modern standards require multi-zone heating control, where each zone is monitored by independent thermocouples to ensure a variance of less than ±1°C.
