CNC Foam Cutting Techniques
1. Hot Wire Foam Cutting
Hot wire foam cutting utilises a heated wire to cut through foam materials with minimal resistance, resulting in a smooth, clean cut. This technique is ideal for achieving precise, intricate shapes and contours on foam materials, particularly expanded polystyrene (EPS) and extruded polystyrene (XPS). Key advantages of hot wire foam cutting include:
- Reduced cutting force, ensuring minimal material deformation
- Smooth, clean cuts with virtually no dust or debris generation
- Capability to produce complex, intricate shapes with ease
2. Oscillating Knife Cutting
The oscillating knife cutting technique uses a high-speed, reciprocating blade to produce clean, precise cuts in various foam materials, including polyethylene, polyurethane, and closed-cell foam. This versatile cutting method is well-suited for a diverse range of applications, from packaging inserts to foam insulation panels. Benefits of oscillating knife cutting include:
- High level of precision and accuracy in cut geometry
- Suitable for a wide range of foam materials, including dense and tough varieties
- Ability to achieve clean, burr-free edges with minimal waste
Innovations in CNC Foam Cutting
