The factory behind
the heater
We are an HTCC factory, not a trading office. Screen printing, lamination, co-firing at ~1,650 °C, electrode plating, assembly and end-of-line testing are done in-house, so a circuit change does not wait on an outside supplier.
From green tape to tested part
The process that makes an MCH element reliable is the one that seals the circuit inside the ceramic. Each step below has an in-process check, and every finished part is electrically tested before packing.
- Screen printing — tungsten / Mo-Mn resistor paste printed on 96% alumina green tape to the designed circuit geometry
- Lamination — layers hot-pressed into a single green body with the circuit fully embedded
- Co-firing — ~1,650 °C in a hydrogen reducing atmosphere for a dense monolithic body
- Electrode plating & brazing — nickel metallisation and lead attachment, pull-tested
- End-of-line test — 4,500 V / 1 s withstand, insulation resistance, rated power, dry-burn ageing, thermal shock, visual 100%
- Assembly — housing, thermostat / fuse, terminals and connectors where the customer buys a module
What we test on every lot
Certificates & compliance
Documents on file, each with its issuing number. Scans of the certificates we actually hold. The ISO 9001:2015 certificate is issued to our Xinghua plant; its scope reads 'manufacturing of industrial electric heating tubes', and that scope line is printed on the certificate itself. CE here means the EMC Directive 2014/30/EU, tested on ceramic plates and rings. RoHS and REACH are third-party tests on submitted samples. Tap any document to open it at full size.
Both utility-model patents are registered to our Shenzhen legal entity, while the ISO 9001 certificate is held by our Xinghua, Jiangsu production site. On the patent scans we redact only the inventor's personal name; patent and certificate numbers, validity dates and scopes are left intact so every document can be verified directly with the issuing body.
Commercial terms
- Samples from 10 pcs · production MOQ typically 1,000 pcs per specification
- Custom samples · standard parts
- T/T 30% deposit · balance cleared before dispatch · L/C at sight
- Third-party testing can be arranged on request
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.
Audit us, ask us anything
On-site or remote factory audits, process questions and document requests are all welcome — they are part of qualifying a supplier properly.
