Plastic profile machines are developing towards "high filling, low foaming, multi-cavity co-extrusion, in-line surface treatment, and AI closed-loop dimensional control":

Foamed wall panels/ceiling lines emphasize lightweighting, thermal insulation, and integrated decoration;

Door and window lines emphasize high weld angle strength and integrated intelligent packaging;

Waterstop lines require ultra-large cross-sections, high elasticity, and chemical resistance;

Yarn-wrapped lines demand high speed, multiple strands, and precise concentricity.

When selecting a model, users should comprehensively consider the raw material formula (calcium powder filling ratio, foaming ratio), cross-sectional complexity, product standards (GB/T 8814, EN 12608, TB/T 3360, etc.), downstream secondary processing requirements such as lamination, embossing, and perforation, as well as workshop length and cooling water quality. The optimal balance between production capacity and dimensional accuracy should be achieved by optimally matching the machine model, calibrating table length, traction force, and cutting method.
