Hybrid Parts  Manufacturers, Traders, Suppliers

For many years, the name of KARWEG has represented quality and customer satisfaction. As a medium-sized production operation from the metal and plastic processing industries, we see our core competences in the production of plastic parts, metal parts und hybrid parts.
Due to our good location within Europe, we are able to react to your wishes very quickly and to react flexibly very quickly.
Since our founding in 1946, we have been able to continually develop our capacities. We put great value on further development in our production methods and optimisation of our production processes. Today, we supplement our state-of-the-art machines with software solutions that are always up to date.
We meet special requirement together with high-performance partners whom we coordinate seamlessly.

We are a German manufacturer of high-performance stamping tools, stamped and hybrid parts (assemblies out of metal and plastic) serving numerous sectors including e-mobility, automotive, medical technology, sensor technology and electronics.
We are a family owned business operating globally with headquarters in Pforzheim, Germany and subsidiaries in the US, India and Sri Lanka.
Many years of experience of our design department and our toolroom allow us to implement the best solutions for our customers even in highly complex projects. In our production lines we combine many different production steps as well to the point of full automation.
With our highly modern stamping machinery including brands like i.a. Burderer (25-80 tons press capacity) serial production in the range of 0,02 mm to 2 mm sheet thickness are our core compentence.
We are an all-in-one partner at each of our location.

More than just plastics

Plastic as a versatile material
has become an important part of our everyday life. They surround us
nearly everywhere and their variety in design, quality and technological
possibilities has increased rapidly over the last years. The spectrum
ranges from ordinary plastics to ultra-light-weight special plastics up
to ultra-hard and space-tested materials. Recently, the industry tends
toward an exchange of metal or glass in favor of lighter elements to
reduce weights and costs.

One-shot and two-shot plastic injection molding

As
a contract manufacturer for customers operating in various sectors, we
produce complex plastic injected parts with one-shot or two-shot
technology. Always on the side of the costumer, we develop constructive
approaches, test their feasibility with fill-analysis (MoldFlow) before
production and produce tailor-made forms in an in-house mold shop. This
shortens the actual process of creating and producing an idea to a
finale product. On customer demand, we also refine products or assemble
complete systems. We process precise parts with weights from 0.1 g up to
400 g.

Plastic injection over-molding of coated glass

PENTACON
holds a patent in over-molding coated glass as used in optical filters.
Other than uncoated glass, coated glass reacts far more sensitive
toward pressure or thermal deformation. We have developed an approach to
over-mold such glass with plastics at a large-scale production.
Even very complex and precise threads are no problem with this method.

Metal substitution and hybrid parts

Due
to rising raw material prices, our customers increasingly change their
production from using high-cost metals toward less costly plastics with
similar or even better qualities. We counsel you in finding an efficient
solution to lower your costs for materials. Ranging from exchanging
single components to a re-design of your products (hybrid parts) up to
the complete material exchange - we have developed a wide range of
technologies and methods to save you costs and material weights.
Usually, our customers come from the automotive industry where products
tend to become increasingly lighter.

Tool and form making

Our
in-house tool shop is a key for successful product development.
Together with our engineering department, we are able to quickly realize
costumer ideas to optimized products. We produce precise and complex
tools at our HSC-milling center and degrading studio, which would not be
possible with common cutting technologies.
