Plastic Molding

TOOL STEEL
Plastic Molding

plastic molding is a demanding and evolving industry. Harsh environments put steel under considerable stress. Corrosion, high temperatures, temperature changes and wear are just few of the most common challenges

Plastics are indispensable in today’s world, serving a wide range of purposes. They are used in mass-produced items such as packaging and reusable bottles, as well as in high-quality products and accessories across consumer goods, leisure, automotive, and the construction industry. Additionally, plastics play a crucial role in high-tech sectors.
