Manufacturing services at ZELTWANGER

Your outsourcing partner for contract manufacturing

Cost reduction, capacity bottlenecks, shortening of supply chains – there are many good reasons why you should outsource the production of your products and components.

At ZELTWANGER, we help you to produce high-precision and complex single and series parts.

Contract manufacturing icon: CNC milling machine

Experience and expertise make us one of the best manufacturing service providers for highly complex and precise machine parts worlwide.

All our manufacturing services are subject to stringent quality requirements. We use the latest measuring equipment to verify and document our work results.

We are also in an excellent logistical position to realize extremely complex projects. We use the latest technologies for part production across an air-conditioned production space of 11,000 square meters.

Take a look at our machine list for an overview.

Screen with 3D model for contract manufacturing

The processing machines used are supplied and controlled via a central network using programs. Innovative 3D programming systems and simulation software enable machining of every complex geometry.

Your requirements – our contract manufacturing service

Have you developed an idea but are unable to implement it in-house?
Are you looking for a partner to help you produce a prototype or for series production?

We can support you through every phase of the product lifecycle – from development to on-time delivery. You decide when we need to enter the process: During development of the idea, with a model, or at a later point.

We manufacture these components

Prototypes
  • Individual design plans
  • Manufacturing support from the initial idea to the product
  • Continuous cost optimization and advice
Machine components
  • Single parts, small-scale production, series production (individual quantities)
  • Binding quotations within three days
  • Short delivery times
  • Maximum quality
  • All surface finish and hardening procedures
3D molded parts
  • Machining of complex geometries with CNC lathes and CNC milling machines with up to five axes

  • Realization using CAD/CAM programming

  • hyperMILL 5 AXIS CAM software from Open Mind with interfaces to all common data formats for a quick takeover and implementation of your design data

We use these technologies

High-precision machining

One of a kind: For precision machining, we use
the DMU 210 μ-Precision with positioning accuracy of up to four µm
and the DMU 210 P with an accuracy package with position tolerance of eight µm across the entire work area.

  • Three times more accurate than standard machines
  • Reference-led temperature control with five controlled axes and maximum travel distances of 2,100 x 2,100 x 1,250 mm
  • Machining of parts of up to eight tons with an exceptional dynamic range
  • 5-axis simultaneous machining in a single setup
  • Maximum component accuracy thanks to temperature stability
  • Sophisticated, extensive cooling of all relevant machine components
CNC milling
  • CNC machining centers in use: 3-axis, 4-axis, and 5-axis milling machines
  • Combination of CAD/CAM system and tool management for machining complex single parts as well as 3D contours
  • Very high vertical depth of production and flexibility in relation to sizes of the parts to be manufactured: max. travel 2,100 mm x 2,100 mm x 1,250 mm
CNC turning
  • CNC lathes with counter spindles and large Y travel to produce parts with diameters from 1 to 800 mm and lengths of up to 2,000 mm
  • Modern tool technologies enable hard machining with CBN, aluminum machining with PCD, or deep hole drilling
Turning/milling/complete machining centers
  • CTX beta 1250 TC 2nd turning/milling centers for effective and economical 6-side complete machining with main and counter spindles
  • Economic production of highly complex components
Milling/turning/grinding centers
  • DMC 80 FDS “duoBLOCK” milling/turning/grinding centers
  • Integration of grinding technology into milling/turning technology for excellent surface finish and dimensional quality
  • Grinding process execution in a single setup
  • Process reliability and high efficiency
  • Perfect fit thanks to grinding finish machining
Round and flat grinding
  • Grinding machines for hard-to-machine materials
  • Meets the highest standards with regard to dimensional accuracy, size accuracy, and surface finish in the micro range
  • High-precision round and flat grinding, non-round grinding, and profile grinding are possible
Wire EDM
  • Formation of the most delicate contours with the highest degree of dimensional accuracy and size accuracy, regardless of the hardness of the material
  • Machining of any electrically conductive material
Stainless steel welding
  • TIG and MIG welding
  • Welded constructions made of stainless steel
  • Glass bead blasting
  • Orbital welding

Quality assurance, laser marking, and part cleaning

Quality assurance icon: Magnifying glass with check symbol

Quality assurance

We develop an individual measuring concept for every component and conduct measurements in-house using the latest technology from Zeiss – from uniformity inspections and curve and free-form surface scanning to reverse engineering including digitization.

We create initial sample test reports for new parts and prototypes. In addition, we also offer 3D contract measuring for parts that have not been produced by us.

Our quality assurance is certified in accordance with ISO 9001:2015.

Laser marking icon: Matrix code

Laser marking

We can mark your components with a company logo, part number, data matrix code, barcode, etc. upon request using the latest laser marking systems.

This is possible for both rotationally symmetrical and cubic components.

Part cleaning icon

Part cleaning

We have the highest standards when it comes to the precision and dimensional tolerance of the parts we produce. The same applies when we clean them.

At ZELTWANGER, we clean using ultrasonic cleaning devices. This means we can deliver our parts in clean-room quality.
