PE Small Pipe Extrusion Line — High-Speed LDPE/LLDPE/HDPE Tube Manufacturing

What It Is

Our PE Small Pipe Extrusion Line is a turnkey solution for producing micro to small-diameter polyethylene tubes (LDPE/LLDPE/HDPE). It combines optimized screw design, precise temperature zones, PLC + touchscreen HMI, and closed-loop line synchronization to deliver uniform wall thickness, smooth surface finish, and stable 24/7 output.

Key Features & Benefits

• High speed & stability – Optimized screw/barrel and melt filtration enable continuous, stable extrusion with consistent OD/ID.
• Precision sizing – Vacuum calibration and multi-stage spray cooling keep ovality low; online diameter/Wall-thickness measurement available.
• Energy efficiency – Insulated heating zones and VFD drives reduce kWh per kg; closed-loop water system optional.
• Smart operation – PLC + HMI for recipe management, line-wide synchronization, alarms, and production data export.
• Fast changeovers – Quick-change die heads and adjustable sizing sleeves minimize downtime for multi-spec production.
• Compliance & safety – CE/UL-ready electricals, interlocks, and EMC design.

Typical Applications

• Wire & cable conduit / lead tubes – Low-friction bore, abrasion resistance.
• Micro-irrigation lateral / dripper line – Flexible, durable small OD tubing.
• Home renovation micro tubing – Water, air, or signal routing.
• Medical & lab tubing (material and regulatory review required).
• Packaging straws / protective tubes / bubble-film skeleton microtubes.

Process Flow

Feeding & drying (as needed) → Extrusion & melt filtration → Die head & vacuum sizing → Multi-stage water cooling → Haul-off (closed loop) → Metering & coding → Cutting/Coiling → In-line QC & packaging

Core Modules

• High-efficiency single-screw extruder (nitrided barrel, wear-resistant screw, optimized L/D)
• Precision die head with quick-change tooling
• Vacuum calibration tank (stable vacuum, level & temp control)
• Spray cooling tanks (closed-loop option)
• Servo or caterpillar haul-off, synchronized with main extruder
• Fly-knife or planetary cutter / servo coiler (small pipe commonly uses coiler)
• Meter counter, inkjet/laser coder (optional)
• Online diameter & wall-thickness gauge with SPC (optional)

Technical Specifications (customizable)

• Pipe OD range: Ø 2–32 mm (options down to Ø 1.5 mm or up to Ø 40 mm)
• Line speed: up to 60 m/min depending on OD, material, and cooling capacity
• Throughput: approx. 80–180 kg/h*
• Energy consumption: 0.28–0.45 kWh/kg*
• Control system: PLC + 7”/10” HMI; recipe/alarms/data export
• Utilities: Electrical per region, process water; closed-loop chiller recommended
• Standards: CE/UL (optional)
  *Actual data depends on your target size, formulation, and configuration.

Quality & Cost Control

• Wall-thickness uniformity: Balanced melt flow + stable vacuum reduce eccentricity.
• Surface finish: Tuned cooling profile mitigates orange-peel and water marks.
• Lower cost per meter: Energy-saving design, low scrap rate, and easy maintenance cut operating costs.
