Production process of pe rod
1. Raw material preparation
- Select HDPE or UHMWPE pellets, drying treatment (temperature ≤ 80 ℃) to remove moisture.
2. Extrusion molding
- Heating and plasticizing by twin-screw extruder, temperature is controlled in stages (160℃→220℃), and the mold is designed to ensure smooth flow path.
3. Cooling and sizing
- Vacuum sizing tank to control the outer diameter, spray water cooling (water temperature 10~25℃) to reduce internal stress.
4. Traction cutting
- The traction speed is synchronized with the extrusion, and the precision cutting equipment ensures that the length error is ≤1mm.
5. Inspection and Packaging
- On-line testing of wall thickness, outer diameter, sampling for hydrostatic test (such as GB/T 6111 standard).
Advantages of pe rod
1. Chemical stability
- Resistant to most acid and alkali corrosion (except strong oxidizers), suitable for chemical industry, sewage treatment and other environments.
2. Physical Properties
- Abrasion resistance 4 times that of steel, high impact resistance (elongation at break >500%), excellent low temperature toughness.
3. Light weight and safety
- Low density, convenient handling; non-toxic and harmless, in line with food grade and medical standards.
4. Flexible processing
- Support electric welding, heat welding and other connection methods, customized size and color.
Application of pe rod
1. Industrial manufacturing
- Seals, sliding profiles: used for wear-resistant parts of mechanical equipment (e.g. cutting plates, bearings).
- Chemical piping: corrosion-resistant transportation piping (gas, sewage).
2. Medical field
- Medical appliances: Surgical instrument parts, catheters (e.g. PE vascular cannulae).
3. Agriculture and Municipal
- Irrigation system: weather-resistant, suitable for agricultural drip irrigation.
- Water supply and drainage pipes: smooth inner wall, high circulation efficiency.
4. Electricity & Communication
- Insulation material: Bakelite board, cable protection sleeve.
In Summary
With its corrosion resistance, high abrasion resistance, light weight and other characteristics, PE rod has become an ideal material in many fields. The production process focuses on precision control, and the product parameters can be flexibly adapted to the demand, which is widely used in industrial, medical, agricultural and other fields.
