Mold making for the automotive and industrial sectors: redefining efficiency
Optimized bending and assembly processes through intelligent mold-making solutions.
Challenges in modern bending mold manufacturing
Anyone operating in the field of bending mold manufacturing—especially in sensitive industries such as automotive or medical technology—regularly faces complex requirements.
Particularly in the production of tubing for fuel lines or battery cooling systems, precision, repeatability, and process optimization are key priorities.
Conventional furnace bending molds are increasingly reaching their limits under these demands: extensive post-processing, high energy consumption, and additional assembly steps drive up costs and extend production times.
Our Solution
In the field of tool and mold making, we develop and manufacture both furnace bending molds and highly optimized steam bending molds.
While conventional processes perform assembly after bending, we have rethought the process: our steam bending molds enable assembly operations to be carried out simultaneously during the bending process.
This not only reduces processing times and costs but also significantly increases process reliability and efficiency.
Advantages of our steam bending molds for industrial applications
By using steam bending molds with integrated assembly, we offer our customers a wide range of advantages:
Reduction of production time
by up to 30%
Significant cost reduction
through process optimization
Minimization of sources of error
through fewer handling steps
Improved component quality
and reproducibility
More sustainable manufacturing
through reduced energy consumption
Project examples
- Successful implementation in mold making
A compelling example is provided by one of our projects in the automotive sector:
The customer had previously relied on separate furnace bending molds followed by manual assembly processes. Together, we developed a customized steam bending mold with an integrated assembly fixture.
The result: significantly reduced production times, savings in energy and labor, and a substantial increase in production capacity – all while maintaining consistently high product quality.
Why steam bending molds are a milestone
The optimization of the steam bending process makes it possible not only to form components but also to assemble parts within the same operation – for example, plug connections in piping systems.
This intelligent integration of process steps makes the entire manufacturing process more robust, faster, and more predictable.
Especially in sectors such as transport machinery and medical technology, where tight timelines and the highest quality standards are essential, this advantage is highly significant.

Mold making by Hein + Gernhard
Steam bending molds enable the integration of assembly processes during the bending operation, significantly reduce process times, and thereby save costs and energy.
They are particularly well-suited for the automotive industry, medical technology, transport machinery, and cleanroom applications.
Depending on the project scope and complexity, development from the design phase to delivery typically takes around 8–14 weeks.
Yes, we offer feasibility analyses and retrofit concepts to efficiently convert existing systems to steam bending.
Our molds are optimized for aluminum, stainless steel, and specialized alloys commonly used in demanding industries.
From the initial requirements analysis through CAD development, manufacturing, quality control, and commissioning, we support our customers in a collaborative and transparent manner.
