PVC roofing tile processing utilizes calendering and extrusion technologies. When selecting equipment, attention should be paid to the precision of the die gap and temperature uniformity; it is recommended to determine these factors through trial runs rather than relying solely on price. A single-screw production line is sufficient for small factories and can be expanded in the future. Leaving room for expansion is a more prudent approach than purchasing large-scale equipment all at once, as it frees up funds for research and development. Surface wrinkling and edge warping are common issues that can arise during production.
