Automotive applications

Vacuum furnaces for automotive manufacturing

Heat treatment for drivetrain components. Vacuum brazing for EV cooling and heat-exchanger assemblies.

Bring your component, material and production target to SYNHTE. We help you select a furnace system for the hardness, dimensional control or joint quality your parts require.

Parts & processes

Built around what
you manufacture.

From a hardened gear to a sealed cooling circuit, the required result determines the process. Explore the applications below to find the right starting point.

01 / HEAT TREATMENT

Strength, wear resistance
and dimensional control

Match vacuum carburizing, hardening and tempering to the steel grade, component section and required material properties.

Transmission gears & shafts
Low-pressure carburizing with gas or oil quenching. Review case depth, surface and core hardness, tooth geometry and distortion.
Dies, molds & production tooling
Vacuum hardening and tempering for tool steels, with cooling selected for section thickness, hardness and dimensional stability.
Engine & precision components
Material-specific thermal cycles for valves, steel parts and engine hardware, aligned with the drawing and the required mechanical properties.

02 / VACUUM BRAZING

Reliable joints for
thermal-management assemblies

Coordinate the base alloy, filler, joint geometry and thermal cycle for assemblies that need dependable heat transfer and leak integrity.

EV battery cold plates
Batch aluminum vacuum brazing for compatible cold-plate designs. Focus on internal channels, joint fill, flatness and leak-test requirements.
Cooling & HVAC heat exchangers
Radiators, condensers, evaporators and intercoolers. Match the brazing route to the alloy and filler, then evaluate batch or continuous production.
Exhaust & EGR coolers
High-temperature vacuum brazing for compatible stainless assemblies, with attention to braze clearance, cleanliness and joint integrity.

Define the result

A clear quality target.
A better furnace specification.

Agree how the part will be inspected alongside the furnace configuration. These checks connect the production cycle to the result your team needs.

Automotive component, process and quality checks
Your component	Process focus	Checks to include
Gears & shafts	Carburizing, quench response and load uniformity	Case-depth and hardness profiles; critical dimensions
Dies & tooling	Heating, cooling and tempering sequence	Hardness, distortion and surface condition
EV cold plates	Filler compatibility, joint fit and fixture support	Leak test, flatness and channel integrity
Heat exchangers	Assembly temperature distribution and braze flow	Leak/pressure test, joint quality and cycle records
EGR coolers	Stainless alloy, braze clearance and cleanliness	Joint integrity, leak testing and dimensional checks

Vacuum brazing systems

Bring joint quality
into production.

Aluminum vacuum brazing furnaceBatch processing for compatible cold plates and heat exchangers. Continuous vacuum brazing furnaceMulti-stage production for an established part family and cycle. High-temperature vacuum brazing furnaceJoining systems for stainless assemblies and compatible braze alloys.

Production fit

Batch flexibility.
Continuous production.

For brazed assemblies, compare the complete production flow: product mix, load handling, changeovers and output per shift.

Batch systems

A practical starting point for multiple part families, development loads and production that needs recipe or fixture changes.

Review usable work zone and complete fixture envelope
Plan parts per load, batch mass and cooling time
Allow for cleaning, changeover and handling

Continuous systems

Review a continuous line when the part family, brazing cycle and planned loading method are established.

Define takt time and transfer between process stages
Match automation to the part and fixture
Plan maintenance access and production availability
