Where engineering meets team spirit, the best solutions take shape.

Tool Design & Mold Making

Your mold, our passion

In our design department, technical expertise meets a real enthusiasm for creating.
Here, we don’t just draw – we think ahead:

  • How do we create molds that remain flexible for future applications?

  • How can our design process already ensure long-term process stability?

In short: Your requirements inspire our ideas – and our experience brings them into shape.

Toolmaking for a plastic part

Precision through teamwork

A mold isn’t created in isolation – but through collaboration: with you, our design engineers, and our toolmakers.
Together, we transform smart concepts into high-precision tools that perform as reliably in daily serial production as they did on day one.

Werkzeugbau, made by BUK

Our molds aren’t outsourced – they’re crafted right here in-house, with care, expertise, and a team spirit you can count on.

“Made by BUK” means: maximum precision, real craftsmanship, and a genuine passion for every detail.

What sets our mold making apart? Here’s what we’re proud of:

  • In-house production of high-precision injection molds

  • Smart combination of modern milling, EDM and classic manual craftsmanship

  • Ongoing maintenance and servicing by our own team

  • Short communication paths, quick feedback loops, and agile adjustments when needed

We believe: every mold is the result of teamwork, technical know-how and a forward-thinking mindset.

And by the way: When time is tight or your tooling package is large, you can still rely on us.
In such cases, we draw on a trusted network of specialized partners – but we stay in the lead.
We coordinate the entire project and keep an eye on every detail to deliver results that meet our quality standards 100%.

Precision to the point

In our in-house toolmaking, we create solutions that meet the highest standards.
Our equipment and expertise enable us to realize a wide range of tools internally.

Our tools age like fine wine – and still deliver every single day

When you have your mold made by BUK, it becomes part of a long line of tools that have proven themselves over decades – day in, day out, cycle by cycle, reliable and precise.
Our molds aren’t short-lived aids, but long-lasting partners in your production.
With every part produced, they show what true quality means – thoughtfully designed, precisely crafted, and continuously maintained over years.

Made to last – because durability isn’t a promise for us, it’s our standard.
And our tools don’t just hold up – they improve over time:
With targeted mold optimizations, we continuously enhance performance, efficiency, and longevity.
Just like a fine wine – only forged in steel.

Our capabilities at a glance:

  • Single- and multi-cavity molds for small and especially large series

  • Tools for insert molding (metal/plastic hybrid parts)

  • Prototype, pre-series and production molds

  • Tool optimization – for peak performance that lasts

Whether it’s a prototype, series tool or special solution – we precisely shape your requirements. Rely on toolmaking that thinks ahead, plans ahead and inspires.

From mold to functional component

At BUK, your plastic parts aren’t just molded – they’re brought to life.
Our production includes additional processing steps such as insert integration or custom coloring.
The result? Ready-to-use components from the very first cycle.
