With our qualified employees, we have specialized in the production of individual parts and small series. Decades of experience lie in the area of boring machine work and the repair of simple technical rolls.

We would like to present our small and humble company who is doing business in CNC turning parts as well as plastic and rubber injection molding, manufacturing.

We have needs to develop and growth in spite of difficult times.
Our geographical position allows us so many benefits in production ,storage and distributing.

We own 1000m2 warehouse and five machines they occupy 300m2 and 300m2 of office space. As far as production is concerned we could expand the production facility or use the rest of the space for warehouse purposes.

We were considering the possibilities of production for foreign markets with the help of partners and achive common interest.

As an owner-managed innovative company that acts as a supplier for all industrial sectors, we attach particular importance to comprehensive personal customer service. Mutual respect and a lived partnership are very important to us.
We develop and produce products according to individual customer requirements. In doing so, we contribute our many years of experience, from development through production to final assembly, in order to develop an optimal solution for every customer requirement from all industries. From customer-specific new development to sample production to special productions in small series including assembly, you get everything from a single source.

We offer you plastic injection molding of the highest quality at fair conditions. In the injection molding process, plastic granules are plasticized and then injected into a mold under high pressure. In this way, plastic parts between 0.1 g and 2500 g can be produced quickly and inexpensively in large, medium and small series.

Due to our customers in the automotive and sensor technology industry, our production is designed to guarantee all the highest quality standards. With the help of the most modern processes and technical systems, we guarantee very high dimensional accuracy, precise weights and accurate colouring. We also help you to optimize the mechanical properties of your product by selecting the optimal material and any post-processing steps together.

Many years of experience with a wide range of products have allowed us to continuously optimize our processes. This enables us to react flexibly to your wishes and to produce a large variety of articles. Our interdisciplinary team examines your molds and products in order to develop an optimal manufacturing process. This reduces waste and process costs, so we can offer you a fair price-performance ratio.

As a company based in the resin business of special and individual production, we specialize in the manufacturing of equipment and containers made of thermoplastics, such as PP, PE and PVC, specialize.
Our production program includes:
- Manufacturing hydraulic tank made of PE, PP and PVC,
- Round and rectangular container with and without insulation,
