Experts for plastic mould steel

The plastic molding steel from the Swiss Steel Group possesses two essential characteristics. On the one hand, it ensures the highest quality of steel, and on the other hand, the steel properties can be individually and optimally tailored to the diverse requirements of the tool or the plastic product. Utilizing state-of-the-art technology, our plastic molding steel meets the highest standards in terms of:

  • Purity
  • Polishability
  • Uniformity in hardness and microstructure
  • Wear resistance
  • Temperature resistance
  • Machinability
  • Toughness and hardness

  • Thermal conductivity

Furthermore, our active and certified quality assurance system (ISO 14001, DIN EN ISO 9001, QS 9000, VDA 6.1 TS 16949, KTA 1401) enables the production of individually customized steel with consistently high quality.

Thermal conductivity

Plastic molding steel is characterized by good thermal conductivity, meaning it can efficiently transfer and dissipate heat. This is crucial for controlling the temperature in the injection molding process and ensuring uniform cooling of the plastic. Effective heat dissipation contributes to reducing cycle times and increasing productivity.

 

Wear resistance

Plastic molding steel is characterized by high wear resistance, meaning it experiences minimal wear even with repeated contact with plastics. This property ensures a long lifespan for molds and tools, leading to lower maintenance costs and higher productivity.

Hardness and strength

Plastic molding steel is characterized by high hardness and strength, making it resistant to deformations and cracking. This is particularly crucial as molds and tools are subjected to high pressures and mechanical stresses during the injection molding process. The high hardness and strength of plastic molding steel enable it to withstand these pressures and ensure precise shaping of the plastic.

New EU steel safeguard measures change framework conditions for Steeltec

The European Union (EU) has adopted new steel safeguard measures that will enter into force on July 1, 2026. Duty-free import volumes into the EU will be reduced by 47% from 34.5 million tons to 18.3 mil-lion tons. Imports exceeding these quotas will be subject to a tariff of 50%, up from the previous rate of 25%. The measures apply to steel producers from third countries, including Switzerland, exporting products into the European Union. Steeltec AG, based in Emmenbrücke and part of Swiss Steel Group, is among the companies affected by the new regime.

Firmly anchored in the rock - Swiss Steel Group’s Top12 anchors secure a new section of road high above Lake Lucerne

100 years – that is the lifetime expected for the new section of the K2b cantonal highway between Vitznau and Gersau following its renovation and modernization. This is made possible in no small part by the Top12 special stainless steel from the Swiss Steel Group, from which the anchors for the retaining wall structure and support elements are manufactured. Over a hundred of these were drilled several meters deep into the steep rock face. They secure the walls and beams that support the new, 350-meter-long section of road. The structure is spectacular not only from a geotechnical perspective but also for everyone who drives over it and enjoys a breathtaking view of Lake Lucerne below.
