200°C in 10 s.Built to your drawing.
Tungsten / Mo-Mn circuits co-fired inside 96% alumina at ~1,650 °C; flat chip, disc / ring and rod / tube, with voltage, resistance and outline set to your drawing.
Documents on file.
Six documents we actually hold, each with its issuing number and issuing body. ISO 9001:2015, CE (EMC), RoHS, REACH and two utility-model patents on ceramic plate construction. Open any row to read the scan at full size.
What we can
actually build
Ranges we hold in production every week, not best-case lab figures. Anything outside this envelope is a conversation, not a no — send the drawing and we will tell you honestly what is possible.
| Parameter | MCH / HTCC (our process) | PTC ceramic | Ni-Cr wire |
|---|---|---|---|
| Heat-up to 200 °C | ≈ 10 s | 30–90 s | 60–180 s |
| Power density | up to 45 W/cm² | typically < 15 W/cm² | limited by wire surface |
| Self-regulating / Curie limit | No — full control via circuit | Yes — fixed Curie point | No |
| Geometry freedom | Chip / disc / rod / tube / custom outline | Mostly disc / block | Coil / wrapped |
| Insulation | Monolithic ceramic, 4.5 kV | Ceramic body | Needs separate insulation |
| Service life | No oxidation of embedded circuit | Ageing of PTC effect | Wire oxidation / hot spots |
Typical values for 96% Al₂O₃ HTCC elements at rated voltage. Full MCH vs PTC comparison, specification guide and a specification checklist for your part.
Why engineers
switch to MCH
A heating element is a thermal interface decision, not a commodity part. Here is what changes when the resistor is buried inside the ceramic instead of attached to it.
Not sure which technology fits your thermal path? Send the space envelope, target temperature and ramp-up time — we will recommend the circuit, or tell you honestly if PTC is the better choice.
Read the comparisonThree families,
one process
One HTCC platform, three geometries. Every series is tunable in voltage, resistance, outline, terminations and assembly — the number is a starting point, not a catalogue limit.
0.7–2.0 mm thick
5–300 W
Centre hole optional
Up to 800 °C
L ≤ 90 mm
Immersion options
A standard chip off the shelf, or the same platform rebuilt to your drawing — the six variables below are what we re-tool.
Every series is built to a customer specification. If your part does not match any of these three series, that is the normal case — send the drawing.
All product pagesWhere they
can go
Eight industries, one co-fired alumina platform. The same element that heats a nebuliser also sits inside an analytical instrument, a 3D-printer hot end or a smart toilet — what changes is the outline, the resistance and the terminations.Customer references are available under NDA.
Medical devices
Nebulisers, incubators and diagnostic modules — sealed elements with no exposed conductor.
Analytical instruments
Precision micro-heating parts for laboratory analysers and detection instruments.
Laboratory equipment
Small constant-temperature fixtures and local heating units inside test set-ups.
Semiconductor
Compact constant-temperature modules and process-assist heaters for wafer tools.
3D printing
Hot ends and heated chambers — fast ramp, compact footprint, isolated surface.
Smart home
Smart toilets, thermostatic fixtures and concealed heating units.
Kitchen appliances
Coffee machines, dishwashers and water heaters — water–electric isolation.
Beauty & personal care
Straighteners, curling irons and beauty devices — thin plate, even face temperature.
Also built for heat-not-burn devices, oxygen sensors and soldering tools. If your product is not listed, the answer is usually still yes — send the drawing.
All applicationsFrom green tape
to tested part.
Screen printing, lamination, co-firing at ~1,650 °C, electrode plating, assembly and end-of-line testing are done in-house — which is why a circuit change does not wait on an outside supplier.
On-site or remote factory audits, process questions and document requests are welcome. They are part of qualifying a supplier properly.
Inside the factory- +Screen printing — tungsten / Mo-Mn paste on 96% alumina green tape
- +Lamination — hot-pressed into a monolithic green body
- +Co-firing — ~1,650 °C in reducing atmosphere
- +Plating & brazing — nickel metallisation, pull-tested leads
- +End-of-line — 4,500 V / 1 s, insulation, power, dry-burn ageing, thermal shock

Questions buyers
ask first
MOQ, tooling, lead time, documentation. Answered up front so your first email can be about the part, not about us.
Still unsure?
Send a rough size, a voltage and a target temperature. A rough sketch description is enough for a first engineering reply — we will help define the rest.
Talk to an engineerSamples start from 10 pcs. For mass production the typical MOQ is 1,000 pcs per specification, and we are flexible for new projects and pilot runs.
Yes. Shape, dimensions, voltage from 3.7 V to 220 V, resistance from 0.3 Ω to 1,500 Ω, power, lead wires, terminals, thermostats and housings are all customizable. Tooling is a screen and a fixture set, not an expensive mould.
Custom circuit design, tooling and pilot lots are supported, alongside standard parts. Send your requirement for an engineering review.
We are an HTCC factory. Circuit printing, lamination, co-firing, plating, assembly and end-of-line testing are done in-house. On-site and remote factory audits are welcome.
Lead-free elements compliant with RoHS and REACH, CE-marked modules, produced under an ISO 9001 certified quality management system. Certificates are available on request.
T/T 30% deposit with order, 70% balance cleared before dispatch; L/C at sight for volume orders. We do not ship on open account: on T/T orders the goods and documents stay with us until the balance has cleared, and on L/C orders payment is secured by the bank against documents. We work on Incoterms® 2020. Air and express shipments are quoted FCA / CIP / DAP; sea freight FOB / CIF. The final term is set per order — by destination, volume and your nominated forwarder. Third-party testing can be arranged on request.
