Ideas.
Brought
to life.
Have a project in mind? We develop and manufacture plastic components, assemblies and pipework tailored to your application.



This is Lang KSTV
Since 1999.
Custom plastics solutions.
From design to installation.
Our focus is custom plastics fabrication. We develop complete 3D designs, tailor components and assemblies to your application and manufacture in our own workshop using 3D printing, laser processing, CNC machining and skilled plastics fabrication, including plastics welding.

Advice & planning
Planned together.
We develop your idea into a complete 3D design, from individual components to coordinated assemblies. Drawings and models make the function, construction and details clear before manufacturing begins.

Manufacturing
Made in our workshop.
We manufacture with care and precision in-house, including to your drawings and individual specifications.

Installation & pipework
Expertly installed.
Whether a component or plastic pipework, our TÜV-trained specialists can carry out the installation at your site. We are a specialist company under Germany’s Water Resources Act (WHG).
Regular TÜV welder qualification tests.
Design and manufacturing
From design
to finished piece.
The requirement: A mobile trolley in which seals can be immersed in a caustic solution for cleaning and transported. No suitable standard solution was available.
Our solution: A custom-designed and manufactured caustic-solution trolley, tailored to its intended use.
Designed to fit together

Custom fabrication
From the first sketch to a precisely fitted part. Individually planned and made in our workshop.
3D printing
Complex shapes and functional parts. Built layer by layer for your application.
Laser fabrication
Precise cuts, engraving and marking. Fine details with a clear purpose.
CNC turning and milling
Precisely fitted contours and complex parts. From one-off pieces to larger production runs.

The people and workshop behind the work
This is where
your parts take shape.
In 1999, Stefan Lang started in a hobby workshop. His part-time venture grew into a family business with its own manufacturing facilities, turning former farm buildings into a place for new plastics solutions.
One-off pieces, new processes and the people we work with: every project adds to our story.
