Double-Sided Heat Shrink Conveyor Oven with English Controls, 630 mm WM-688
Our WM-688 carries wire harnesses with pre-positioned heat shrink sleeves through a 630 × 240 × 80 mm heated passage on a heat-resistant PTFE mesh belt. 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 10 kg load. We test the sleeve and complete assembly to establish the temperature and residence time.

Key features
- Use the 630 × 240 × 80 mm heated passage to select by the full part clearance, including connectors and fitted sleeves.
- 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 10 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-688 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 conveyor support 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-688 quote, share the sleeve size and the approximate dimensions of the part it covers. We'll check which configuration fits your assembly.

WM-688 — common questions
How do we select the working space?
The heated passage is 630 × 240 × 80 mm. The complete part, fixtures and sleeves must fit the confirmed loading pattern.
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?
Compare WM-686 for single-sided heating and WM-687 for double-sided heating. The WM-688 has an English printed control panel and an optional supply configuration.
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.
