Who we are



The service focus of SFK - Schulz GmbH, service, manufacturing and plastics technology - is the small-and large-scale production and distribution of turned and milled parts made of steel, plastics, aluminum, and zinc, as well as the construction of devices and equipment for special purposes.

In these areas, we work very closely with operations in the Republic of Lithuania.
Here, we see ourselves as an external supplement to the German market and offer for the above mentioned areas complex, cost-effective solutions and our services.

We take care of our customers the complete manufacturing and logistics operations of selected individual parts or assemblies.

Our company started in 2001 with the principles of success and continuity in production, quality and honesty in service.
With our experienced specialist staff, we have been active in automobile and cast model making for many years.
We also produce small and large parts in series production for the automotive industry and specific spare parts for the steel industry.
We develop the parts from the design to the finished product. Mold developments for individual and series production, for the foundry and for the automotive industry
as well as reverse engineering is part of our repertoire.

At the end of 2017, the company was reorganized and staffed in order to be active in more sectors. In this context, our company continues to operate without any loss of quality in the production of polystyrene molds, aluminum injection molds, plastic injection molds, rubber molds, sheet metal molds and parts printing with its casting model area.
One of our partner companies can produce up to 20 tons of machine housings/castings.
Series parts are produced using a 750-ton extrusion press.
We also work very closely with other companies with whom we can meet all of your requirements.

With our research and development studies, we would be happy to accompany you in your projects as a solution partner.
Our company strives for long-term and reliable cooperation with you.

h2> Die-cast zinc /h2>

On our 20 PLC-controlled casting machines we manufacture zinc products from the zinc alloys Z 410 and Z 430 according to DIN 1774, primarily for the furniture and window industry, but also for other areas of application.Is produced with modern machinery that has a clamping force of 50 tons and are on the current state of technology. Because of our size we produce machinery parts up to about 500 g and a length of about 250 mm.



For further processing of these parts are



* Drill, cut, thread cutting, deburring, trovalieren

* Finishing (yellow chromating, blue chromate, silver surfaces / chrome-6-free, nickel, black zinc coating, KTL coating ...)

* Packaging (cardboard, octabins, bags, plastic packaging, wire baskets ...)



according to customer requirements.



h2> Plastic Injection Mould /h2>

Various plastic injection parts, inter alia, for the window industry are manufactured on 6 injection molding machines. Is produced with modern machinery that has a clamping force of 50 tons and are on the current state of technology.



The plastic parts range from 1 g to 200 g piece weight.We process plastics such as PP, PS, ABS, PA6, PBT, POM and Megol. The packaging and logistics is done according to the customer.



h2> Mould /h2>

The molds for zinc and plastic parts are designed and manufactured in-house tool. The design department works with the CAD system (AutoCAD 2004 and Inventor 8) and the CAM system (MasterCam 9). It can take place a data exchange formats such as on DWG, DXF, IGES, Step and satellite.



All initial samples are measured by us and upon customer a first sample test report is created. The forms must be kept for safety in a special fireproof storage room.
