How We Cut Steel
Istar Machining uses the best machines to cut your steel parts:
- Fiber Laser Cutters (6kW-12kW) These make very clean cuts in thin steel. Perfect for detailed parts with small holes and tight corners. Great for parts that need to look good.
- High-Definition Plasma Our plasma cutters work with steel up to 150mm thick. They cut faster than other methods and cost less for big parts.
- 5-Axis Waterjet Cutting This uses water and tiny bits of sand to cut steel without heat. It’s perfect for CNC cutting thick steel or making parts that can’t have any heat damage.
