Engineering and prototyping for customized product development

From the initial idea to the finished component – all from a single source.

Challenges in engineering and prototyping

When developing new products, companies face a variety of challenges: short development cycles, high demands on functionality and quality, and the need to keep costs and resources under control from an early stage.

Particularly in industries such as medical technology, automotive, aerospace, or semiconductor manufacturing, precise implementation, flexible adjustments, and rapid time-to-market are critical.

Many suppliers only become involved at the manufacturing stage – yet real competitive advantages are created when engineering and prototyping are considered from the very beginning.

Our Solution

Engineering and prototyping from a single source

We support our customers right from the initial idea and provide comprehensive assistance throughout the product development process.
Our services include:

By fully integrating engineering, design, manufacturing, and assembly in-house, we reduce interfaces, save time, and ensure consistent quality – without loss of information or delays.

Advantages of our engineering and prototyping solutions

With our experience and technical capabilities, you benefit from numerous advantages:

Direct access

to engineering, manufacturing, and assembly expertise

Fast development cycles

through efficient prototyping

High flexibility

for changes during product development

Cost-efficient implementation

through optimized processes

Experience with a wide range of materials

tubes, sheet metal, turned and milled parts, assemblies including pneumatics and electrical components

Use of modern technologies

such as 3D printing for initial functional prototypes

Why engineering and prototyping ensure project success

A structured development process that closely integrates engineering and prototyping minimizes sources of error and increases efficiency.

Rapid testing of different variants enables well-founded decisions based on real results – not just theoretical assumptions. Especially in dynamic markets such as aerospace, cleanroom technology, or consumer goods, this approach is crucial for implementing projects faster, more reliably, and more cost-effectively.

Engineering and prototyping at Hein + Gernhard

Our services are aimed at customers in the medical technology, aerospace, automotive, semiconductor manufacturing, cleanroom technology, logistics, and consumer goods industries.

Thanks to 3D printing and rapid coordination, initial functional models can often be produced within just a few days.

We work with a range of materials, including plastics (PLA, ABS), aluminum, steel, and stainless steel – depending on the application and project requirements.

Our engineering services range from the initial concept idea through CAD development to manufacturing optimization, including functional testing.

Following a requirements analysis, engineering and prototyping take place.
We then support you through to series production and beyond.

Yes, we also offer solutions in special-purpose mechanical engineering – from custom assemblies to complete bespoke systems.
