A tubular element cast into an aluminium body gives you heat spread over a face instead of a line — uniform surface temperature, no hot spots, and mechanical strength that survives clamping. Machined, drilled and tapped to your drawing.

Ranges we hold every day. Anything outside them is possible — it just needs a conversation before the drawing.
| Plate size | 100 × 100 up to 600 × 600 mm; round plates Ø80 – Ø400 mm |
|---|---|
| Thickness | 12 – 40 mm (element burial depth ≥ 8 mm from the working face) |
| Power | 200 W – 6 kW per plate · 2.5 – 6 W/cm² face loading |
| Voltage | 120 / 230 / 400 V, single or 3-phase |
| Body material | Aluminium ADC12 / 6061 (standard), bronze or brass on request |
| Embedded element | Tubular SS321 / Incoloy 840, Ø8 – Ø12 mm, formed to follow the plate outline |
| Surface finish | Machined flat 0.05 mm, Ra 1.6; optional anodised or PTFE coating |
| Machining | Drilled and tapped holes, counterbores, slots, sensor pockets, cable channel |
| Sensors | Thermostat pocket Ø6 / Ø8, Pt100 / Pt1000 pocket, over-temperature cut-out |
| Terminals | Ceramic terminal block, IP54 box option, high-temp lead 300 mm standard |
| Max face temperature | 350 °C continuous (aluminium), 400 °C short term |
| Testing | 100 % hipot 1500 V / 1 s, IR ≥ 100 MΩ, R-value and leak current recorded |
Four things we control in the process, and four reasons elements fail in the field.
Element bent to the plate outline
Jigged at controlled burial depth
Aluminium poured around the element
Face, edges, holes, pockets
Hipot, IR, flatness, thermal image
200 pcs repeat size · 500 pcs new tooling · samples from 1 pc

Yes, if the element is Ø8–12 mm with a defined cold zone. We will re-form it to the plate outline and confirm the bend radii before casting.
10–14 days for the casting pattern, 15 days for the first plates after drawing approval. Repeat orders run 18–22 days.
0.05 mm over the full face for plates up to 400 mm, 0.10 mm above that. We can hold 0.03 mm on small plates if the application needs it.
We can fit a thermostat pocket, supply a capillary or rod thermostat, and pre-wire to a terminal block or IP54 box so the plate arrives ready to connect.
50 plates for a repeat size, 100 for a new casting. Prototype plates from an existing pattern start at 5 pieces.
Send a drawing, a sample photo or just the application — we will tell you what watt density and sheath you need before quoting.
