Manufacturing

Precision and quality for over 80 years

METZEN manufacturing originated from the traditional FMS Gochsheim and takes place in our 20,000 m² manufacturing center in addition to our other production facilities. It allows us the industrial contract manufacturing of high-quality and certified welded and special constructions. With a great depth of added value and the approvals for the production of components in the area subject to approval, we manufacture both one-offs and medium-sized batches.

Our product focus is on:

Most of our products are used in the energy distribution, rail transport, automotive and food industries, as well as in various niches of mechanical engineering, plant engineering and steel construction.

On top of individual components and ready-to-install units, we also manufacture complete machines, including regulation and control technology. Our senior engineers develop them from planning and design to project management and installation, finishing with the complete operating documentation.

(Biography)

We offer a broad range of services

Service

Our employees are service-oriented and competent. They maintain close personal contact with the customer. In dialog, they record all customer requirements in order to manufacture products of the highest customer benefit.

Construction

The design engineers create component drawings for production. The design is done externally or by the customer. Overview drawings are converted in detail on the basis of “production drawings”. Furthermore, sketches, individual part drawings and parts lists are created for external procurement.

Procurement

Under high quality standards, we complete our products with purchased and standard parts from our reliable suppliers, including certification.

Prefabrication

  • Prefabrication of individual components
  • SN preparations
  • Rolls from Ø390 to 3000mm length
  • edges up to 300t bending force
  • Tube bending

Welding construction

  • Materials: aluminum materials, chrome-nickel materials (including duplex, Hastelloy), structural and pressure vessel steels, fine-grained steels, aluminum and steel castings
  • Certified welders according to DIN EN ISO 9606
  • Div. welding equipment (MIG-MAG-WIG-E hand)
  • Welding robot
  • Submerged arc welding
  • Stelliting for wear resistant surfaces

Mechanic

  • 5-axis machining with driven tool (X=7000mm, Y=3000mm, Z=1000mm, load up to 20 tons)
  • Turning with driven tool (up to Ø2000mm, height 2000mm, load up to 6 tons)
  • We will be glad to machine your castings

Surface treatment

  • Sand and glass bead blasting (cabin LxWxH 6mx3mx3m, load up to 4 tons).
  • Wet and powder coating incl. cross cut and coating thickness measurement for onshore and offshore
  • As well as all common surface coatings (e.g. zinc, nickel, chrome, …)

Assembly

Assembly and commissioning in our own production halls as well as externally, nationally and internationally. Machines and assemblies as well as complete systems are assembled ready for operation. Of course, we are also available for conversions, maintenance and service.

Quality assurance

Tests according to the requirements of the regulations

  • Strength testing up to 150 bar (higher pressures on request)
  • Helium leakage tests according to customer-specific leakage rate
  • NDT according to DIN EN ISO 9712 – Weld seam testing: VT2 – MT2 – PT2 – UT2 – RT2 – LT2
  • Quality assurance incl. EMPB/FAIR and various acceptance guidelines – 3D measurements, radiographic, ultrasonic and crack testing

Transport

  • We will organize the transport of your components for you so that they arrive at their destination on time.
  • If required, with truck-mounted crane loading and unloading and special or heavy haulage.
  • Special and heavy transports as well as crane loading and unloading are also part of our know-how.
