WE MAKE CNC MACHINING AND MOULDS FOR THE PLASTICS INDUSTRY

Core business of our company is the mold. With decades of experience in this field, excellent quality and punctual delivery, we develop a good reputation in the industry.

We design and manufacture tools for plastic injection molding and die casting and devices of all kinds

The maximum disk size of the molds is approximately 500 x 500 mm. All the usual manufacturing processes such as hard milling, die sinking and wire EDM and electrode manufacturing done in the house.

We will gladly advise you even at the part design to find a priori technically feasible and affordable solutions.

All tools of our facilities are patterned in the connected molding department - of course with first article inspection report.

Our plastic injection molding parts can all commercially available thermoplastics PA, ABS, PC, PET, PBT, PS finished (except silicone and PVC). We have specialized in small precision parts. Maximum weight of parts: 220g

We carry out surveys, splash advantages and zero series as well (large) series for production.

Made at the client quality records and statistical analysis.

Depending on your needs, we deliver the parts are assembled, treated mechanically (by drilling, milling, turning o. Etc.). In addition, the home is done, ultrasonic welding, with our BRANSON-conditioning or pad printing with our Tecaprint pad printing machine.

As a specialist in the manufacture of plastic parts, especially



Plastic coils, we offer the following services:



Planning and advice of your article


Construction of injection molds according to sample or drawing


Cost-effective production of injection molds in tooling


Processing of all thermoplastics such as PA, PS, ABS, PE, PP, TPE, etc. up to a shot weight of 120 grams.


Wage spraying at tool position


Color according to your wishes


Due to our warehouse production, short delivery times are guaranteed.

Our Injection-Molding-Services-Division manufactures injection molded plastic parts in cooperation with our long-standing partners in Eastern Europe and Asia. Our core competence is the utilization of cost advantages, while ensuring the highest quality standards at the same time. Our services range from development and production of prototypes, to production of small batch series to mass production with ongoing quality management. We can also take care of your stocking and your logistics inside of Europe.

Kalmbach - profiled in performance

Innovation, flexibility and extreme quality and standard optimization are the three pole "performance profile" of my company.

Founded in 1964, since 1994 in my hands and from 2001 at the new location in Tübingen Pfrondorf.

Customers with my staff and me to work together with confidence for many years, know that they are in capable and competent hands.

Based on a wealth of experience we offer you the complete width of the innovative production of particle foam - mold making:

From design test tools and prototypes to series production of foam molds for EPS, EPP and EPE production.

Maintain the best possible continuity of the CAD data of the desired part in the design, our CAM systems in the work preparation to CNC machining - center in manufacturing - which is at the core of our concept of good work.

In addition, we work with our ultra-modern machinery in contract manufacturing. Main focus: the sophisticated machining of aluminum.

Today at Kalmbach highly trained and constantly trained staff with years of professional experience. In order to maintain this high standard in the future, we will make of course yourself.

When it comes to new developments, a decent price - go for money or maintaining the tightest deadlines, you can rely on us.

Ask for my staff and me with your tasks and projects. We like profile for you!
