The core highlight is that it meets the FDA and ISO 13485 medical grade certification, with mirror polishing accuracy up to Ra≤0.05μm, avoiding bacterial growth caused by residual plastic melt. It adopts a temperature-controlled cooling jacket, which can accurately control the mold temperature to ensure uniform wall thickness of the tubes. Different from ordinary plastic extrusion molds, its flow channel is designed with rounded transitions to reduce the shear stress of plastic melt and avoid bubbles or whitening of the tubes. The mold is detachable and cleanable, convenient for disinfection treatment, with a service life of more than 50,000 strokes, meeting the mass production requirements of medical consumables.
The die material is 420 stainless steel, with Rockwell hardness of 45-48 HRC, the cavity mirror polishing accuracy is Ra≤0.05μm, the surface is passivated to meet the FDA 21 CFR Part 177 standard, suitable for 100-300 ton plastic extruders, the normal extrusion speed is 1-5 meters per minute, the weight of a single set of molds is 150-300 kg, the inner diameter of extruded tubes ranges from 2-50mm, the wall thickness ranges from 0.2-2.0mm, equipped with composite cooling system of air cooling and temperature control jacket, with temperature control accuracy of ±1℃, compatible with medical grade plastic raw materials such as PP, PE and PVC, passed the ISO 13485 medical device quality management system certification, with detachable design for easy cleaning and maintenance.
It is mainly used in medical device manufacturing enterprises, used to produce disposable infusion tubes, catheters, nasal oxygen tubes, medical drainage tubes and other plastic tube products. It can be matched with medical extrusion production lines of well-known brands such as KraussMaffei and Toshiba, and can customize exclusive cavities according to the customer's tube inner diameter, wall thickness and special-shaped section design, supporting the extrusion production of medical special-shaped tubes, helping enterprises meet the compliance requirements of medical products and improve the product yield and production efficiency of medical tubes.
