Characteristics of vertical monochrome silicone extrusion production line: 1. This production line can meet the production of large-diameter (greater than 20mm) and thin-walled (less than 1mm) pipe products, ensuring the shape error of the products. 2. This production line utilizes gravity to freely drop vertically, resulting in more perfect product straightness and external dimensions. 3. The production line is equipped with an anti stretching automatic detection system, which ensures that the product does not experience sudden stretching during the extrusion process. The consistency of the extruded shape of the product can achieve an error of ± 0.1mm. 4. Screw and barrel material: The inner hole of the barrel is made of double alloy centrifugal casting, with a thickness of ≥ 2mm. The screw material is 9Cr18MoV and undergoes quenching and tempering treatment; High hardness, high wear resistance, lead-free, halogen-free, in compliance with FDA certification requirements.
