Arpek has capacity to cast annually over 5.000 tons aluminum. Arpek offers comprehensive machining and assembly capabilities. With these capabilities, we are able to supply from "ready-to-install" product range up to complete modules.

"Sustainability needs competitiveness and effectiveness"

Typical industry efforts to improve the die casting quality focus only on the die casting machine process technology. However, a more advanced, reliable die casting machine is still no guarantee for efficiency and quality. That’s why Arpek takes an "All in One Approach" to the process. Our development team considers every phase. From simultaneous engineering through part development and die casting cavity design, to melting treatment, casting, machining and assembly process through to "All in One Approach".

"Efficiency made by Economical Process"

HPDC is an efficient and economical process offering a broader range of shapes and components than any other manufacturing technique. Computer based control of the shot profile (Real time technology) allows us to realize component features that opens completely new horizons in design. Optimum use of the material/performance ratio allows for an efficient and ecological die casting process. Thanks to a correct calculation and optimum advance casting simulation with MAGMA SOFT®, less casting pressure is required than with standard traditional processes. This has a positive effect both on the die life and the die casting machines.

Some of the advantages:

High Speed Production

Dimensional Accuracy and Stability

Strength and Weight

Multiple Finishing Techniques

Simplified Assembly

"Extensive development competence"

Arpek is nominated as a development partner for a large number of high-status projects in the automotive industry. Our engineers collaborate with customers from the start of the project to bring Arpek extensive development competence. However, in order to remain ahead of the market, Arpek conducts its own R&D projects.

"Integration produces process efficiency through service by added value"

  • Integrated cooperation is the basis for a utility-oriented supply chain management system in which Arpek provides its partners added value by virtue of its strengths in operations.

  • Downstream processes such as impregnation, Surtec coating, vibration deburring, shot blasting, CNC processing, washing and assembling complete the process and supply chain. As a full-service supplier, Arpek can therefore minimize the cost of administration and logistics for its customers and apply overall equipment effectiveness.

  • Customized service for development of material alloys and product processes.

The foundry is equipped with 9 Casting Island for Integrated Production the most advanced and fully robotized equipment.

Arpek produces:

  • Power-Train Components

  • We support all well-known OEMs, engine and transmission manufacturers in developing components and in the entire process of designing light weight engineering solutions.

  • The staffing of our development teams is interdisciplinary. Materials specialists and foundry experts work hand in hand here. We do not start only when we get a component drawing from the customer, with our function and system know-how, we contribute to the development with advice from the outset. Our understanding of the challenges of components in modern engines, transmissions and suspension systems allows us to look for targeted solutions. The outcome is especially light castings that are highly resilient precisely at those points where the greatest loads occur in operation.

  • Because every component is different, we also design the data driven casting & machining processes for every component individually. Automated processes with intelligent control loops and fully integrated process data management guarantee the highest possible quality, and that with every casting & machining method used. The manufacturing depth is based on the customer needs. We manufacture from the casting and the subsequent heat treatment to machining parts down to the final dimension, and then testing, washing, coating, assembling and shipping them straight to the line.Our experience in casting and system know-how oriented around the present and future demands of modern vehicle development.

  • Casting Simulation

  • At Arpek, we use MAGMA SOFT® to simulate the pouring and solidification. Our advantage: we are able to set the many parameters quickly and reliably. We need only a few iteration loops in order to design components such that they achieve the mechanical strengths that will be demanded of them in operation later. A cluster computer with numerous processors in the background makes sure that the results of the calculations are quickly available.

  • Engineering Tools
