Metal stamping

Over 12.5 mil. stamped parts per year

We specialise in the production of components with complicated shapes in medium production runs. We can employ our more than twenty years of experience in close cooperation with your designers, with whom we create the ideal design for the components. We optimise the components so that during production we can eliminate problems on an operative basis and thus avoid needless extra costs for projects. Production is effective and fast, and we deliver by the deadline.

Advantages of sheet metal stamping

  • from the economic aspect it is most advantageous method for mass production
  • progressive stamping allows us to manufacture thousands of items per shift
  • we manufacture smaller runs starting from 10,000 items, and the runs can go into the millions
  • possible cooperation starting with the development of the component thanks to cooperation with prototyping production at the Sheet Metal Processing division

Key features of Lakum press shop

  • possibility of 3D measurement with an accuracy down to one thousandth of a millimetre - cast-iron quality control
  • possibility of printing 3D templates
  • we avoid extra costs through consultation before and after the start of production
  • we confirm our quality with quality certificates ISO 14001 and IATF 16949
  • we combine the press shop with manual processing of sheet metal
  • we ensure the subsequent operations such as welding on connecting elements or fitting rubber inserts etc.

close cooperation on projects

We stamp items out of various types of material (steel, galvanised and stainless steel sheets, copper, brass and bronze alloy sheets) on mechanical presses. Thanks to the progressive dies we can manufacture an unlimited number of component variants from sheet metal with a thickness ranging from 0.5 mm to 3 mm on presses with a working force from 25 to 400 tons. After the die is fitted in the press and the coil of production material is fed into it, finished components drop out of the press and are sent for further processing.

Presses 25 - 400 tons

Customers work with us long term because they utilise other associated productions in addition to our experience in stamping metal. Lakum ensures subsequent finishing of the products by tumbling, degreasing and surface finishing of products by cataphoresis, powder coating and galvanisation. Our affiliate company Massag performs bending of pipes and wire, manual and robotic welding, and a range of other surface finishes.

Comprehensive ensuring of production and a high level of expertise in consultation before and during production allows us to guarantee the agreed prices for our customers, to transparently ensure a uniform and high level of quality, and allows us to react on an operative basis to any changes during production.

Case study

Sodecia / anti-corrosion surface treatment

Since the start of our business relationship with the company Sodecia we have implemented 43 projects for leading automobile manufacturers. In practice, this means more than 25,963,583 surface finished parts. Project of surface finish for mass produced parts: End customer FORD – Parts BRKT STRT TL/GT LH/RH and Pivot Asy Gate Strut LH/RH requires surface finish complying with high standards and norms. It involves a combination of two technological procedures: ● zinc electroplating according to standard FORD WSS-M1P85-B3● cataphoretic painting according to standard FORD WSS-M2P177-C3 Project of surface finish of special material: The requirement for coating of product Sodecia Wasserkasten Stirnwand for AUDI was demanding in many respects. The product requires coating according to standard VW13750 Ofl x634 with minimum coating thickness of 35 microns. As this is a relatively large flat part, moreover made of the special material CR3-EG47/47-E-PO, coating in the required scope is technologically demanding. The preparation of the entire process required a large volume of sampling. Thanks to the experience of our experts, we discovered during the sampling that the product is susceptible to scratching. We fine-tuned the parameters and details of the entire process. We included a completely new product packaging approach in the process, and damage has no longer occurred. Completed, coated components reach the end customer at the assembly site in good order and with no faults caused during transport.
