zwerenz industries gmbh

Precision in series production, based on a continually developing quality managementsystem according to DIN EN ISO 9001:2008.

Fully automated production and modern equipment are basis to be able to offer high quality products at low prices in the global competition.
On our CNC rotary machines we produce conventional and also sophisticated automatic turned parts in single, small, middle and mass series.
In this connection we are working with conventional machining steel, various stainless steels, aluminum, copper and brass alloys as well as rods made from polyester an various other plastics.
Furthermore, we process also not easily machinable chromium alloys and various plastics.

Machine parameters:

• Rod diameter from 4 to 65mm
• Speed up to 6300 r / min
• Milling-, vertical- and cross edits
• Driven tools
• Front and rear side machining by main and counter spindles
• Bar feeders for rods up to a length of 3 meters

CNC milling

On our CNC milling machines we produce conventional and also sophisticated milled parts in single and small series.
In this connection we are working with conventional machining steel, various stainless steels, aluminum, copper and brass alloys as well as rods made from polyester an various other plastics.

Downstream manufacturing techniques

• Electroplating
• Paint
• Powder coating
• Laser marking
• Printing
• Assembly

Materials:

Machining steel, stainless steels, aluminum, chromium, copper and brass alloys, polyester and various plastics.

The modern method of laser marking makes it possible to process almost any material.  

A large number of our machines operate using the CO² process, which allows writing, pictures or similar designs to be incorporated into workpieces using a laser beam. This process also makes it possible to cut desired contours from workpieces.  

Another type of marking is achieved using YAG lasers. This technique makes it possible to mark / engrave almost all types of metals.  

The third area is marking using the colour change process. This involves using materials which change colour through the addition of specific components by marking with a laser technique at the relevant point.

Laser welding is the fourth area which we are using in our own mould making departement for welding plastic injection moulds and also zinc diecast moulds. We are also offering laser welding in form of wage to our customers. Almost all grades of steel are welded in our company.

In this future-oriented sphere of industry, zwerenz industries is one of the leading companies anywhere in Europe. The machinery, which is designed to be state of the art, and the specialist staff who are employed make it possible to cater for almost all customer requests.  

In the area of mould making we offer our customers a comprehensive range of services. We are particularly noted here for our high quality standards. Precision in all working steps makes this possible.  

The implementation of individual customer wishes, flexible handling of orders and a high level of customer proximity are basic prerequisites that we can offer.  

Overview of services

• Flat grinding
• Hubbing spark machining
• Turning
• Milling
• Lasering
• Laser welding
• Tempering
• Constructing

Plastic parts manufactured on modern machines - this makes it possible to process highly sensitive plastics in an efficient way.  

The machinery we use consists of injection moulding machines with locking pressures of from 25 to 200 to. The fact that the majority of manufacturing takes place fully automatically provides the basis for flexible, cost-effective and environmentally friendly mass production.  

The company’s own mould making unit with a design department allows the tracks to be created during the actual planning and development phase in such a way that an optimum result is obtained thanks to error-free production.  

Other manufacturing techniques 

• Finishing/marking processes such as:  
  pad printing or laser engraving
• Assembly and commissioning of assemblies
• Overmoulding of metal parts with plastics

The automatic hot-chamber die casting machines which are used guarantee reliable production with a constantly high level of quality. They produce locking pressures of from 75 kN to 1250 kN for cast parts with a weight of from 0.05 to 1,000 grams.  

Optimised production processes allow even extremely thin-walled cast parts to be manufactured with outstanding characteristics.  
The company’s own mould making unit incl. design is available to deal with issues such as saving material or weight for customers. This means that even in the foundation of each cast, that is to say in the mould, the tracks can be controlled in such a way that error-free production and an optimum result is obtained.  

Sizes of machine used

Depending on the nature of the parts, we are able to manufacture small parts weighing from 0.05g each. To do this, we use our smallest type of machine with a locking pressure of 5 tonnes. If we are processing large solid parts, we use our die casting machines with a locking pressure of 125 tonnes and this allows us to cast a part having a weight of up to 1000g.  

We are able to select from the following machine types 

• 5 tonnes
• 20 tonnes
• 50 tonnes
• 80 tonnes
• 125 tonnes
