This mold adopts S136 mirror mold steel, which is polished to a surface roughness of Ra0.05μm, so that the produced pipes have no scratches and high flatness. The external annular water cooling system can accurately control the mold temperature, ensuring that the error of pipe wall thickness is ≤±0.05mm. The modular design allows quick replacement of the die core rod, adapting to pipe production of different calibers. Compared with traditional plastic extrusion molds, it can improve production efficiency by 30% and reduce raw material loss by 20%, which is especially suitable for large-scale plastic pipe production enterprises.
Overall mold size: 800mm×450mm×220mm; Mold material: S136 mirror mold steel; Cavity machining accuracy: ±0.01mm; Surface roughness: Ra0.05μm; Number of cooling circuits: 12 groups; Compatible extruder screw diameter: 50-120mm; Applicable pipe diameter: 20-300mm; Rated working temperature: 220-300℃; Single set mold weight: 15kg; Customizable product types: solid bar, hollow pipe, plastic strip and other plastic profiles.
It is mainly used for the production of domestic water supply and drainage pipes, agricultural irrigation pipes and industrial fluid transportation pipes, and can also be used for the extrusion processing of plastic decorative strips and wire sheaths. It serves plastic product factories, pipe processing plants and wire and cable enterprises, and can customize plastic extrusion molds of different calibers and cross-sectional shapes according to customer needs.
