Sandblasting is a cost-effective and efficient treatment option to remove scale, rust, coating residue, etc. Despite the name, the technique has not involved actual sand for quite some time. Instead, steel cast shot is used for blasting. RUBIG operates a number of blasting machines. A good solution for mass-produced parts are our belt shot blasters, while individual parts of up to 1,000mm or parts for partial blasting may be processed on a rotary-table blast machine. We also offer sandblasting on a contract basis.


RUBIG Die Forge is certified for welding operations in accordance with EN ISO 3834-2. We produce welding modules up to a maximum size of 500 x 500 x 500 mm from laser cut parts, supplied parts, profile sections, rotary parts, etc.

Our facilities support the efficient production of individual parts and small series, while larger series are manufactured with the help of welding robots. All work is performed by skilled welders. We also offer process audits in cooperation with test and inspection institutes. Our in-house annealing furnaces enable us to weld preheated components and perform subsequent heat treatment. Microstructures, hardness levels etc. are tested in our in-house laboratory.

Hardening and tempering of mass-produced components

Modern belt furnace systems support the hardening and tempering of water-quenchable steels, such as

  • carbon steel: C22 / C35 / C40 /C45 ...,
  • Q&T steel: 30Mn5, 25CrMo4, 27MnCrB5.2, ...,
  • Q&T structural steel: St52-3 (S355JR, etc.), St60-2 (E335)

in a continuous flow process.

Achievable weight per unit: 0.05 - 1.5 kg

Max. main dimensions: approx. 200 x 50 x 100 mm

Calibrated hardness testing equipment is available for compulsory testing. We can also perform in-house laboratory testing and crack tests (fluxing) upon request, and we offer post-processing sandblasting.

Vibratory grinding

As a manufacturer of stainless steel forged parts, RUBIG offers the option of polishing the forged and blasted surfaces. Vibratory grinding in roundtub vibrators is ideal for mass-produced components. A variety of grinding instruments and additives is used to smooth the surfaces, which may then be polished as and if required. We also offer this procedure for customers’ parts (e.g. laser cut, turned or milled parts, etc.) for cost-efficient and reliable deburring and edge-rounding.

Magnetic particle detection

Many parts require in-process or final crack testing. To meet the requirements of our customers, we at RUBIG can readily detect magnetic parts of up to 700mm length. We also test components for our customers on a contract basis and offer post-processing steps such as cleaning, sandblasting, preserving and more.


The manufacture of drop-formed parts requires the deburring, punching, and debossing of components after forging. RUBIG utilizes a variety of presses with a pressure force of up to 360 tons. Using the appropriate tools, these machines can also be employed for other processes, such as punching or bending. We are happy to offer these services with tools provided by our customers, and we are well equipped to manufacture such tools in-house.
