Pipe & Profile Haul‑Off Cutting Machine for Small-Diameter Extrusion

Pipe & Profile Haul‑Off Cutting Machine for Small-Diameter Extrusion

A space‑saving downstream solution that combines a high‑traction belt haul‑off with an inline cutting module, engineered for small plastic pipes and compact profiles. Its synchronized motion control, non‑marking traction belts, and precision cutting options (chipless, saw, or planetary) deliver smooth surfaces and consistent lengths across PVC, PP, PE, PA, and specialty micro‑profiles—maximizing quality while minimizing footprint.

Product Features

Innovation at a Glance

• Integrated traction + cutting: a unified frame with shared encoder ensures the haul‑off and cutter stay phase‑locked, preventing tension spikes and length drift.
• High‑grip, non‑marking belts: specialized polyurethane or silicone covers provide strong traction without scuffing sensitive or glossy profiles.
• Adaptive cut logic: selectable cutting modes (chipless for dust‑free, saw for rigid sections, planetary for round tubes) matched to material and wall thickness.
• Precision nip and wrap control: fine‑resolution pressure and adjustable contact length stabilize thin walls and reduce ovalization on small ODs.
• Intelligent drives & recipes: electronic gearing with stored parameters for line speed, nip, and cut length enables rapid, repeatable changeovers.
• Clean, quiet mechanics: vibration‑damped drivetrain and guarded kinematics lower noise and enhance operator safety.

Material & Process Compatibility

• Polymers: PVC/uPVC, PP, PE, PA, TPE/TPV, and co‑extruded micro‑profiles.
• Heat‑aware handling: belt and blade selections accommodate warm extrudates; S‑curve ramps avoid print lines during start/stop.
• Cosmetic finish focus: tool paths and belt wraps tuned to prevent chatter and melt smears on high‑gloss surfaces.

Application Areas

Construction

• Mini conduits, irrigation capillaries, glazing beads, sealing carriers, window/door trim inserts, and light‑duty protective profiles.

Furniture & Interior

• Cable trunking, edge trims, mini skirtings, appliance fascia profiles, and decorative strips for cabinets and fixtures.

Automotive & Mobility

• Washer/vacuum micro‑tubes, harness protection sleeves, interior trim carriers, sensor sheathings, and lightweight clips.

Industrial & Lab

• Instrumentation tubing, pneumatic micro‑lines, pilot/R&D profiles, and OEM specialty mini‑sections requiring tight tolerances.

Technical Specifications

Throughput & Accuracy

• Line speed: 0.3–26 m/min (extended ranges available).
• Product range: typical pipe OD 2.5–36 mm; comparable cross‑sections for compact profiles.
• Length tolerance: with shared encoder and appropriate cutter, typical deviation ±0.4–0.8 mm depending on material and speed.
• Cut types: chipless (guillotine/flying), circular saw (dry or mist), planetary (for round tubes).

Haul‑Off & Drive System

• Dual endless belts with adjustable contact length; belt covers in PU or silicone, optional heat‑resistant formulations.
• Independent servo or vector VFD drives with electronic gearing, slip compensation, and phase trim.
• Nip actuation: pneumatic with precision regulator; optional closed‑loop nip control and digital readout.

Cutter Module & Controls

• Cutter actuation: servo/pneumatic per configuration; quick‑swap tooling for fast format changes.
• PLC/HMI with multilingual UI, recipe management, analog/pulse line‑speed following, and encoder‑based cut‑length control.
• Safety: interlocked guards, E‑stop circuits, cutter door switches, and alarm diagnostics.

Energy & Utilities

• Installed power: 2.0–5.0 kW total (drive + cutter, configuration dependent).
• Electrical: 380–460 V, 3‑phase, 50/60 Hz (other voltages on request).
• Air: 0.5–0.7 MPa for nip and cutter clamp/actuation (where applicable).

User Recognition

Customer Outcomes

• Conduit producer improved cut‑length CpK and reduced dust by switching to chipless cutting with encoder synchronization, lowering post‑cut cleaning by 40%.
• Furniture‑trim line reported smoother edges and fewer cosmetic rejects after adopting non‑marking belts and phase‑locked motion.

Market Reception

• Praised for compact integration that frees floor space and simplifies downstream alignment.
• Procurement teams cite a favorable total cost of ownership from efficient drives, durable belts, and modular cutter tooling that shortens downtime.

Competitive Advantage

• One‑frame, one‑encoder architecture reduces mechanical stack‑up errors common in separate units.
• Scalable from lab/pilot lines to multi‑shift production with consistent recipes and predictable maintenance intervals.
