WHITE GOODS

Components for household appliances — from metal to plastic, from a single source

Leading segment of our production

For white goods manufacturers, we produce metal, plastic, and metal-plastic components used in mixers, kitchen appliances, refrigerators, freezers, tumble dryers, and washing machines. We combine plastic injection molding, metal-plastic overmolding, sheet metal stamping, and spring manufacturing into a single production process — from product development to assembly of the final unit.

Work is carried out in accordance with ISO 9001 and IATF 16949, with traceability and quality control in our own laboratory.

Production process by product group

Mixers and kitchen appliances

Plastic injection molding (bowls, lids) using food-safe processes, combined with electric motors, metal blades, and feet. Whisks and metal parts are made by stamping and metal-plastic overmolding — the metal insert is injection-molded directly into the plastic tool, eliminating a separate assembly step.

Refrigeration and freezing appliances

Plastic containers and handles — large-volume molding focused on dimensional stability at low temperatures and UV resistance for parts exposed to light.

Tumble dryers and washing machines

Feet and doors — a combination of stamped metal frames (up to 500 t press force) and molded plastic covers that must withstand vibration and thermal loads over long-term use.

Technologies we use

Plastic injection molding — including 2K molding (two tools for one product, two injection units or an external injection unit); clamping force 35–1000 t
Metal-plastic overmolding — metal insert and plastic in a single production step
Sheet metal stamping — progressive tooling for high-volume production of metal parts
Springs — compression, tension, torsion, and leaf springs, as well as wire-formed and bent elements
Assembly and integration — supply of complete subassemblies, not just individual components

Technical capabilities

Plastic injection molding	clamping force 35–1000 T, Battenfeld and Krauss Maffei machines
2K injection molding	dual tooling for one product / two injection units / external injection unit
Metal forming / stamping	press force 5–500 T
CNC machining (turning)	diameter 3–65 mm
Springs	compression, extension, torsion, leaf, bent elements
Tool shop	in-house tool manufacturing for injection molding and metal forming

Materials

PP POM ABS PC PS SEBS

With glass fiber reinforcement, flame-retardant additives, anti-foaming additives, and colorants added as required. For parts in contact with food (mixer bowls, kitchen appliance parts), we use food-safe grades. The metal portion of our program covers steel, stainless steel, and other alloys for stamped and metal-plastic components.

Quality, Development, Sustainability

ISO 9001 and IATF 16949

Quality control in our own laboratory.

In-House R&D

Our own R&D group, registered with the Slovenian Research Agency (ARRS No. 2786) — product development from concept to series production.

Sustainable Energy

Part of our electricity comes from our own solar power plant (since 2011).
