Discover the Ease of Machining Delrin®
Prototype with confidence! Delrin® offers the opportunity to machine prototype gears that will have close performance to a molded gear.
This is unlike machining glass filled resins which result in fiber orientation that’s very different from a molded part.
Delrin® is an easy material to work with in terms of machining. It is a stable material and cuts very well, which makes precise, tight tolerances easier to achieve.
To get the best prototype results:
- Design for Delrin®. Keep an even wall thickness and include fillet radii, especially if your prototype part will be molded in production.
- Keep cool. While machining, remember that Delrin® is sensitive to heat at or above 250°F (121°C).
- Stay sharp. Maintain a sharp cutting edge. Use of cutting lubricant will help maintain a precision cutting edge.
- Clamp lightly. While Delrin is stiff it’s still a plastic; light clamping will avoid surface damage.
