Double-Sided Far-Infrared Heat Shrink Conveyor Oven with Teflon Mesh Belt WM-670PH

Name: Double-Sided Far-Infrared Heat Shrink Conveyor Oven with Teflon Mesh Belt WM-670PH
Brand: Wiromac
SKU: WM-670PH

CE Certified HS Code 8419.89 Belt 0–6 m/min

The WM-670PH shrinks pre-positioned sleeves as wires ride through a 630 × 180 × 80 mm heated tunnel on a Teflon mesh conveyor. Far-infrared tubes heat from above and below under two independent temperature controllers set anywhere up to 260 °C, and belt speed adjusts steplessly from 0 to 6 m/min so dwell time matches each tube specification. The belt carries up to 20 kg of product, the 3.6 kW oven runs on 220 V, and the whole unit measures 1200 × 480 × 580 mm at 50 kg.

Key features

Double-sided far-infrared heating with separate upper and lower temperature control shrinks sleeves evenly all round in one pass — no flipping parts and no cold side
Stepless 0 – 6 m/min belt speed tunes dwell time to the tube, so thin-wall sleeves do not scorch while heavy-wall tube still gets full recovery time
High-temperature Teflon mesh belt releases hot sleeves cleanly and feeds work through hands-free, carrying up to 20 kg of product at a time
Twin digital thermostats and a front speed dial make a proven setup repeatable — note the numbers once and rerun the batch any day

What it processes

Batch shrinking of insulation and strain-relief sleeves on harness ends after tube insertion
Marking sleeves and color-code tube on control-cabinet and appliance wiring
Continuous shrink of protective sleeving on terminals, busbars and small assemblies fed along a bench line

Suited for: continuous shrinking of pre-inserted sleeves on wire ends, terminals, marking tube and small assemblies that fit a 630 × 180 × 80 mm heated tunnel — batch work fed hands-free on a Teflon mesh belt with heat from both sides. Not suited for: bulky harness mid-sections and parts over the 80 mm tunnel clearance — for those, pick the WM-664 infrared harness heat shrink oven, which shrinks harness sections up to Ø100 mm.

Send 2–3 meters of your wire with your actual tube loaded, and we run it through this oven on video — temperature settings and belt speed in frame — before you commit.

WM-670PH — common questions

How do I set temperature and belt speed for a new tube type?

The upper and lower heater banks each have their own digital controller adjustable up to 260 °C. Start from the tube maker's recommended shrink temperature, then trim belt speed between 0 and 6 m/min until recovery completes just before the tunnel exit. Once a combination works, the two temperatures and the dial position are all you need to record to repeat it.

What size of work fits through the tunnel?

The heated space is 630 mm long, 180 mm wide and 80 mm high, and the mesh belt is rated to carry 20 kg of product. Wire ends, terminals, marking sleeves and small assemblies pass side by side in rows — anything taller than 80 mm or wider than 180 mm will not clear the tunnel.

What does this oven not do?

It only heats. It does not cut tubing to length, slide sleeves onto wires or print markings — those steps happen upstream on other heat shrink processing machines, and parts over the 80 mm clearance need a different oven format.
