PVC decorative panel production line

PVC decorative panels imitating marble—this equipment uses a modified PVC formulation as the base material, with a surface treated using a specialized UV process. The surface features realistic marble and wood grain patterns; compared to free‑foamed materials, the surface layer is not only flat and smooth but also exhibits significantly higher skin hardness and rigidity, with mechanical properties markedly superior to those of free‑foamed products, offering broad application prospects.

Common Problems and Their Solutions in the PVC Sheet Production Process

Compared with other extruded plastic products, the production of skin‑formed, low‑foam PVC articles not only requires excellent plasticization and molding under a specified melt pressure, but also imposes specific technical requirements on the size, number, and uniformity of the foam cells, as well as on the skin layer’s thickness, hardness, gloss, and surface finish. The quality of the foamed structure depends not only on the formulation and raw materials, but is also directly influenced and constrained by factors such as the extruder screw’s shear performance, melt pressure, temperature, extrusion (traction) speed, die lip clearance, sizing‑die gap, and cooling‑water temperature. Consequently, skin‑formed foamed plastic products present greater technical challenges than conventional extruded plastics, leaving numerous unresolved issues—both practical and theoretical—that warrant further investigation and resolution by industry professionals.
