The PTFE ultra-thin-wall tube extruder is a professional high-precision extrusion equipment specially developed for the production of micro-bore, ultra-thin-wall PTFE tubing. Adopting advanced PTFE paste extrusion technology and vertical pressure stabilization structure, this equipment solves the core pain points of traditional extrusion machines, such as uneven wall thickness, tube body deformation and low yield in ultra-thin tube production. It is the core intelligent manufacturing equipment for producing high-performance PTFE thin-wall tubes widely used in medical devices, precision electronics, aerospace and industrial high-end fields.
Different from conventional plastic extrusion equipment, the PTFE ultra-thin-wall tube extruder adopts professional cold extrusion paste forming process, which is the most mature and reliable process for ultra-thin PTFE tube production at present. The equipment mixes PTFE resin with special extrusion auxiliary agents to form uniform paste raw materials, and realizes constant-pressure and low-speed stable extrusion through precision hydraulic pressure control system and polished micro-die set.
Equipped with a non-gravity-disturbance vertical extrusion structure, it effectively eliminates the tensile deformation of unsintered PTFE blank caused by gravity, avoiding tube wall cracks, eccentricity and uneven thickness. The precise die gap control and real-time pressure monitoring system ensure that the polymer molecular chains are arranged uniformly and longitudinally, greatly improving the structural density and mechanical stability of ultra-thin-wall tubing.
Superior Equipment Features & Technical Advantages
1. Ultra-High Dimensional Precision
This extruder supports mass production of ultra-thin-wall PTFE tubes with wall thickness as low as 0.0127mm (0.0005 inches), achieving ultra-tight tolerance control of ±0.005mm. The customized high-precision polished die (surface roughness Ra≤0.2μm) eliminates inner wall scratches and burrs, ensuring smooth and flawless tube inner and outer walls. The intelligent concentricity calibration system keeps the product concentricity above 90%, realizing consistent dimensional accuracy in batch production.
2. Stable Constant-Pressure Extrusion System
Equipped with PLC full-automatic pressure regulation module, the equipment maintains stable extrusion pressure within 10-20MPa, effectively solving the problem of wall thickness deviation caused by pressure fluctuation. The intelligent real-time monitoring system tracks extrusion speed, pressure and temperature data in real time, automatically adjusts operating parameters, and ensures zero difference in product quality in long-term continuous production.
3. Intelligent & Efficient Production
Integrating automatic feeding, constant-pressure extrusion, fixed-length forming and intelligent fault diagnosis functions, the equipment realizes one-stop unmanned production. Compared with traditional equipment, it improves production efficiency by 30% while reducing material waste. The optimized structural design supports long-term stable operation with low noise and low energy consumption, greatly reducing enterprise production and operation costs.
4. Diversified Customization Capacity
The equipment supports flexible production of various specifications of ultra-thin-wall PTFE tubing, including micro-bore tubing, multi-lumen tubing, medical etched tubing and catheter liner tubing. It can be customized according to customer’s outer diameter, wall thickness, lumen structure and special process requirements, providing one-stop personalized extrusion solutions for different industrial scenarios.
