Electric Panel Heater Manufacturing
Thank you for the interest shown by viewing this page. Without belabouring you with detail, local raw material suppliers are not able to supply us as required. As in any business, we see this as an opportunity which we intend to grasp by entering into licensing agreements with global partners. At present we export to several destinations, we estimate that partnerships with global players will enable us to expand our global markets considerably. 
Below is a brief description of the panel heater manufacturing process, with a few drawings and pics:
THE WALL MOUNTED ELECTRICAL PANEL HEATER 425W, 230 V AC
Manufactured from a ceiling board mixture of high density cement fibre 4.7mm to 5mm thick and 600mm square.
The product specifications are available.
1. The board is cut or cast into panels and the hole for the caps is drilled through both boards to allow for the connection caps.
2. Check the panels for cracks with a damp cloth.
3. Check the panels for moisture content.
4. Place panels in drying oven to remove any moisture at 60°C for 2 hours. Oven drawings with electrics are available.
5. Cool slowly and evenly for heat stress release. 
It prevents cracking.
6. Drill a hole of 70mm diameter in the one corner of the matching pair. Diamond encrusted hole saw can be used or tungsten tipped drill bits mounted in drill jig. Drawings of jig available.
7. Clean panels interior of dust for better adhesion.
8. Wire the panel with resistance wire in the configuration set out. Full specifications of the wire are available.
9. Tape down the wiring layout as per drawing. Now place the wired board face up and apply the silicone over the entire board covering the wires with a flat spreader. Wipe off any excess. Repeat on other board 1mm thick.
10. Place the two boards together and align the sides and holes. Press firmly together and place in the press. A pressure of 20 tons should be applied.
11. The panel is removed from the press and the excess silicone squeezed out by the pressure is cleaned away – the boards are realigned if necessary.
12. Return to press and allowed to cure for 24 hours.
13. After curing the 9mm holes are drilled in each corner 20mm from the sides. These are for the fixings.
14. Hang the panel from one of the corner holes and spray paint both sides with a coat of good PVA acrylic paint. Allow it to dry then apply another coat. Once dried remove any over spray with fine water sandpaper.
15. Place in oven again at 60°C for an hour or more to remove any moisture left from the painting cycle. Allow it to cool slowly and evenly. Once cooled place in pvc bag to prevent soiling.
16. Clean resistance wire ends and trim. Connect the ends with nylon tin coated ferrule to the lead ends.
17. The ends of a Light Emitting Diode (LED) can be inserted into the ferrules at the same time to work as a power indication lamp or pilot light. Details and specs are available.
18. The lead is threaded through the rear cap before connection. Mould design and dimensions are available. The plastic pins and special wall plugs are from the same family mould.
19. Press caps carefully together and insert the lock screw at the back which prevents the caps inadvertently separating exposing the insulated wires. The cord is rolled up and fastened with a cable tie and packet containing the fixings.
20. The heater is now placed in it’s packing 
configuration and lowered into the box. The box is sealed and stacked. All stencils and cutters for the boxing specifications are available and so are the drawings.
