Frequently Asked Questions (FAQ)
- Can this line produce both HDPE and PPH tanks? Yes, the machine is designed to handle HDPE, PPH, and PP materials. A simple parameter adjustment and material change let you switch between materials without additional hardware.
- What is the minimum and maximum tank diameter? Standard range is 600–4000 mm. For larger diameters (up to 5000 mm) or smaller sizes, please consult our sales team for a customized solution.
- How long is the delivery time? Typical lead time is 45–60 working days after order confirmation, depending on the configuration and current production schedule.
- Do you provide installation and training? Yes, we offer on-site commissioning and training for your operators (travel expenses included for up to 7 days). Remote troubleshooting is also available.
- What raw materials are compatible? The extrusion unit works with HDPE (PE80/PE100), PPH, and PP pellets. For recycled materials, we recommend using a quality filter and degassing system (optional).
- Can the line be upgraded later? Absolutely. Our modular design allows adding functions like automatic belling for pipes, a thicker winding head for heavy-duty tanks, or a servo-controlled cut-off saw.
- What certifications does the machine comply with? The line holds CE certification (optional) and our factory is ISO9001/ISO14000/OHSAS18001 certified. Specific country standards (e.g., ASTM, DIN) can be met with appropriate calibration.
- How to ensure consistent wall thickness for tanks? Our PLC system uses closed-loop control based on real-time laser measurement, guaranteeing thickness tolerance within ±0.5 mm.
