Plastic Mould Steels Applications
Where Precision Takes Shape
Tool Steels for Demanding Plastics Applications
Plastic moulding is an essential technology shaping modern life. Automotive components, consumer and optical electronics, eyewear, medical/pharmaceutical equipment are all manufactured using highly sophisticated moulds. At the core of every reliable and high-performance mould lies one decisive factor: the mould steel! voestalpine plastic mould steels are engineered to meet the demanding requirements of todays plastics processing industry – where precision, durability and surface quality are non-negotiable.
Plastic mould steels are essential for manufacturing high-quality plastic components in demanding industries such as automotive, electronics, packaging, and medical devices.
The unique requirements of plastic moulding demand steels that combine wear resistance, corrosion resistance, polishability, and thermal stability to ensure long tool life and superior component quality.
Why Plastic Mould Steels Matter
Plastic processing places extreme demands on tooling materials. Injection moulding, blow moulding, and extrusion require steels that can withstand:
- High temperatures and pressures
- Abrasive fibre-reinforced plastics
- Corrosive environments (e.g. PVC)
- High-volume production cycles
Using the right steel directly impacts tool life, product quality, and cost per part.
Key Properties of Plastic Mould Steels
Wear Resistance
Essential for processing glass- or carbon-fibre reinforced plastics that increase abrasive wear.
Corrosion Resistance
Protects moulds against aggressive plastics and humid environments, ensuring long service life.
Excellent Polishability
Delivers flawless surface finishes, critical for optical, medical, and consumer products.
Thermal Conductivity
Supports efficient cooling, reducing cycle times and improving productivity.
Toughness & Dimensional Stability
Maintains accuracy and prevents cracking under repeated stress cycles.Key Properties of Plastic Mould Steels
