Waterjet Cutting Service
Dotmar’s waterjet cutting systems give you a clear advantage when precision matters and material performance can’t be compromised.
You’re not just getting a cut-to-size component; you’re working with a team that understands engineering plastics and how they behave under pressure, load, and application-specific demands.
Waterjet cutting uses a high-pressure stream of water, often combined with a fine abrasive, to cut through plastic with exceptional accuracy. The result is a clean, precise finish without heat, distortion, or stress.
What is Waterjet Cutting?
Waterjet cutting is a process that uses a concentrated stream of water, pressurised to extremely high levels, to cut through materials. For tougher plastics, an abrasive is added to increase cutting power.
Waterjet cutting doesn’t generate heat, thereby preventing melting, warping, or internal stress fractures. The outcome is a smooth edge, tight tolerances, and the ability to produce complex shapes with consistency.
Dotmar’s advanced waterjet cutting systems allow for intricate designs, sharp internal corners, and clean cuts across both thin and thick materials.
Advantages of Waterjet Cutting for Engineering Plastics
Choosing waterjet cutting gives you practical, measurable benefits that mean less rework, better performance, and greater confidence in the final product.
- High precision and accuracy for complex and detailed components
- Clean, smooth edges with no need for secondary finishing
- No heat-affected zones, eliminating the risk of distortion or material weakness
- Capability to cut thick plastics and intricate geometries with ease
- Reduced material waste
- Environmentally friendly process
- Versatility across a wide range of plastics, supporting multiple applications
- Cost-effective for prototyping and low-volume production
Plastic Materials Suitable for Waterjet Cutting
Dotmar technicians work with a broad range of engineering plastics, each selected and processed to suit your application.
The most effective plastics for waterjet cutting include:
