Materials and Capabilities
With the ever changing face of engineering comes the need to "step-up" the search for new materials and improved ways to make products to suit applications and opportunities. You will find our staff ready to discuss the next generation in applications for FluoroPolymers and Thermoplastics.

Machining of Plastics
The following guide lines are recommended by Pacific West for the machining of plastic products:
- Keep heat to a minimum and ensure heat build-up in the part is avoided.
- Keep tools sharp at all times.
- Ensure that only the cutting edge contacts the material.
- Apply coolants (per guidelines) where heat is generated.
- The lower rigidity of plastics may require support or plugging to avoid deflection in thin walled sections.
- Cutting tools should be high speed steel or carbide tipped for production runs, especially on graphite or glass filled materials.
- Machining Tolerance
- It is much larger than for metal.
- Watch stress relieving where a large body of material is removed.
- Thermal conditioning may be required after pre-machining on some parts.
- Allow a tolerance of 0.1 - 0.2% of nominal size.
- Be aware of thermal expansion in larger parts or panels where fixings are required.
- Refer "Solutions" on this website.
- Minimum tolerance for small dimensions 0.05mm.
Speed and Feed charts and other support information is available from Pacific West. Please give us a call if you need any further help with your plastic products.
