Company development
Built around the work of making reliable replacement parts.
Our role begins before a part reaches the catalogue. We review the application, define the interfaces, develop the tooling, control production and retain the inspection evidence needed for an aftermarket supply program.
Expanded application engineering, tooling and prototype validation for replacement programs.
Connected forming, brazing, assembly and inspection into an integrated factory workflow.
Supporting global aftermarket enquiries across passenger and commercial vehicle applications.
What we do
From product development to finished-part production.
Our factory integrates research and development, product design, tooling, injection molding, stamping, brazing, assembly and testing. These manufacturing stages connect application requirements to finished replacement parts.
The core range includes auto radiators, A/C condensers, heater cores, evaporators, intercoolers, oil coolers, and additional microchannel and liquid-cooling heat exchangers for passenger and commercial vehicles.
For replacement-market enquiries, the most reliable starting point is the OE number together with the vehicle make, model, chassis, production year, dimensions, and connection details.
Factory & engineering
Product development connected directly to manufacturing.
Engineering review begins with the OE reference, vehicle application, dimensions, mounting points, connections, and customer requirements. Development, tooling, laboratory testing, inspection, and production feedback then support repeatable aftermarket programs.
- Application and dimensional review
- CAD development and tooling coordination
- Prototype validation before production release
Manufacturing scope
One production program across five thermal systems.
Radiators, A/C condensers, intercoolers, heater cores and evaporators each have different interfaces and test requirements. Our factory approach keeps product definition, tooling, process control and final inspection connected to the specific application.
