Raw Materials

At Šumer d.o.o., the quality of our finished products begins with the careful selection of raw materials. Whether working in our metals or plastics department, we source only high-grade materials that meet the technical and visual requirements of each project.

Metals Department

Our metals department works with a broad range of materials to meet diverse engineering demands:

  • Stainless steel
  • Structural steel
  • Tool steel
  • Spring steel
  • Aluminum and aluminum alloys
  • Brass
  • Copper
  • Titanium
  • Platinum
  • Other materials upon request

Each material is selected based on the specific mechanical, thermal, and corrosion-resistance properties required by the application.

Plastics Department

  • We injection mould a wide range of plastic types for both technical and visual applications:

    • PP, PS, PPS, TPE, POM, PC, ABS, PE, PA
    • Other engineering plastics upon request

To enhance performance or aesthetics, we incorporate technical additives such as fibreglass reinforcement, flame retardants, anti-foaming agents, and colouring agents. We also produce injection-moulded components certified for food contact applications, ensuring full compliance with food safety standards.

Why Raw Material Selection Matters

The right material choice directly impacts product durability, dimensional stability, and manufacturing efficiency. Our engineering team works closely with clients during the design phase to recommend the most suitable material for each part — balancing cost, functionality, and longevity.

With decades of experience in both metal and plastic processing, Šumer d.o.o. is equipped to handle complex, multi-material projects from prototype to full-scale production.
