Aluminum-Frame Open-Sided Heat Shrink Conveyor Oven, 630 mm WM-691

Name: Aluminum-Frame Open-Sided Heat Shrink Conveyor Oven, 630 mm WM-691
Brand: Wiromac
SKU: WM-691

CE Certified HS Code 8419.89 Heating space 630 × 180 × 80 mm Conveyor 0–6 m/min

Our WM-691 uses an open-sided 630 × 180 × 80 mm heating zone for a selected sleeved region of a harness or assembly. A heat-resistant PTFE mesh belt carries the work; we confirm how the remaining harness and connectors are supported outside the heating zone. The machine uses far-infrared heating with double-sided coverage and a 0–260 °C setting range. Conveyor speed adjusts over 0–6 m/min with a listed 20 kg load. We test the sleeve and complete assembly to establish the temperature and residence time.

Key features

Use the 630 × 180 × 80 mm heating zone for the sleeve region; we confirm clearance and support for the remaining harness and connectors outside it.
Match heating exposure to the sleeve by adjusting conveyor speed over 0–6 m/min and recording the approved setup.
Carry work on the heat-resistant PTFE mesh belt with a listed 20 kg load; we confirm the loading pattern with the actual assembly.
We set the voltage for your country and ship the English interface and manual.
For wear parts, every quote lists them with unit price and the location they ship from.

What it processes

Batch heat shrinking of sleeves already positioned on harnesses
Heating terminal insulation and cable-joint sleeves in an assembly line
Conveyor heating trials for suitable small electrical assemblies

The WM-691 matches a conveyor heating process to prepared sleeved assemblies. Heating space, loading pattern and residence time are selected together so the sleeve can recover while the surrounding assembly is checked.

This build uses a aluminum-profile frame. Send the line layout and the full workpiece dimensions so we can confirm the conveyor arrangement and installation space.

For an approval trial, send the complete assembly with the sleeve positioned. We film the heating pass and show the finished recovery before ordering. For a WM-691 quote, share the sleeve size and the approximate dimensions of the part it covers. We'll check which configuration fits your assembly.

WM-691 — common questions

How do we select the working space?

The heating zone is 630 × 180 × 80 mm. We confirm the sleeve position, fixtures and support for the remaining harness and connectors outside the heating zone.

How do we set temperature and conveyor speed?

We run the actual sleeve on the complete assembly and adjust heating and belt speed to verify sleeve recovery and the surrounding insulation. The approved values and loading arrangement are recorded for the job.

Which configuration should we compare?

The WM-691 uses an aluminum-profile base. The WM-692 has an English printed control panel. Both list a 630 × 180 × 80 mm heated passage; we quote the selected build.

What is included in the electrical and spare-parts confirmation?

We set the voltage for your country and ship the English interface and manual. For wear parts, every quote lists them with unit price and the location they ship from.

Can we see our own assembly processed?

Send the sleeve material, starting and recovered diameters, sleeve length, complete part dimensions and expected batch volume. We film a trial and show the heated assembly before you confirm the machine.
