What Sinomas does
Sinomas operates as a custom heating solution provider under the legal entity Sino Material Technologies Limited, headquartered at C201 Building 3, 500 Jianyun Road, Shanghai 201318, China, with a wholly-owned European sales and support subsidiary, Flex Heat GmbH, based in Meerbusch, Germany (HRB 87382). Founded in 1998 and employing 51–100 people, the company designs and manufactures flexible and rigid heating elements and integrated temperature sensors for industrial OEM customers across automotive, medical, semiconductor, aerospace, and general industrial sectors.
The product portfolio spans six distinct heater technologies — silicone rubber, polyimide (Kapton), PTFE (Teflon), mica, thick film on stainless steel (SS430) or alumina, and co-fired metal ceramic (MCH) — plus application-specific families for motor anti-condensation and EV/energy-storage battery thermal management. Differentiating technical capabilities include etched foil resistive circuits (nickel-based alloy, ~50 µm), bifilar conductor layouts for EMI-sensitive environments, thick film printing directly onto metal or ceramic substrates with watt densities up to 50 W/cm², and integrated Pt100/Pt1000 RTDs, thermocouples, NTC thermistors, and thermal fuses. Manufacturing is certified to ISO 9001 and IATF 16949, with UL recognition, CE marking, and RoHS/REACH compliance on the product range.
The business model is engineering-driven direct OEM sales: customers submit application specifications (geometry, voltage, temperature range, sensor requirements, volumes, certifications), Sinomas engineers a custom solution, the customer approves drawings and prepays in full, and production lead time is typically 3–5 weeks. All revenue is one-time project-based custom manufacturing with no catalog pricing, no stock inventory, and no recurring component. The marketing footprint is limited to a bilingual (English/German) company website (flexheaters.com) and direct inquiry handling; no third-party distributors, digital marketing programs, or external funding are referenced.

Revenue model
- Custom Heating Element Manufacturing: SINOMAS manufactures all products to customer-specific requirements — no stock inventory is maintained. Customers must provide full payment prior to production. Revenue is generated through one-time custom manufacturing orders. Standard samples are available upon request; prototypes require custom development and are quoted separately. The business model is pure project-based custom manufacturing with no recurring revenue component.
- Temperature Sensor Cable Assemblies: Flexible Pt100/Pt1000 RTD sensors and other temperature sensors (thermocouples, NTC thermistors) are sold as separate products or integrated with heating elements. These can be supplied as standard catalog items with custom configurations or fully custom sensor assemblies.
- Prototype and NPI Services: Custom prototypes built to specific designs require a separate custom development process and are quoted separately from production orders. This includes prototype heating elements, custom sensor integration, and design verification samples.
