Iskra ISD - Plast d. o. o. uses advanced technologies for injection moulding plastic materials. We've been developing, upgrading and improving them for more than 60 years. Today, we mainly work for demanding customers in electric and automotive industry. We cooperate with them closely, strive for ever higher goals and are becoming better and better.

Our key services are designing and making moulds, moulding parts from thermoplastics and thermosets, and assembling of these parts in units.

Our production programme includes:

  • product designing and tool making,
  • moulding thermoplastics and after-treatment,
  • moulding thermosets and after-treatment.

Moulding thermoplastics

  • Clamping forces: from 25 t to 350 t
  • Product mass: max. 1 kg
  • Materials: PC, PA6/66, PP, SAN, PMMA, ABS, POM, PBTP, PPS, LCP, PEI, TPE …

Our key activities are injection moulding and assembling mainly technical and visible parts, with the highest accuracy.

We also perform after-treatment and subsequently assemble different parts in units. In this way we offer a product which has a higher added value. We also purchase all the parts needed.

  • Overmoulding of metal and non-metal parts,
  • Assembly with robots (insertion of sleeves, screws, etc.),
  • Machine deburring,
  • Ultrasonic welding,
  • Tampon printing,
  • Hot foil stamping,
  • Manual assembly.

Our advantages and quality:

  • Complete »one-stop shop« service,
  • Automated processes regarding the batch size,
  • Competitive prices for our products and services.

Moulding thermosets

  • Clamping forces: from 55 t to 400 t
  • Product mass: max. 1.5 kg
  • Materials: PF, MF, UP

We use the technology of injection moulding thermosets. The following operations or assembly are performed subsequently:

  • Overmoulding metal parts,
  • Machine or manual deburring,
  • Manual assembly.


High quality is assured and implemented in compliance with the requirements and directives from the ISO 9001 standard.

At customer's request, documentation for certain products in the automotive industry is prepared in accordance with directives from the ISO/TS 16949 standard.
