Can Delrin be molded?
Can Delrin be molded?
(OP)
We've been machining white delrin for our prototype designs but now are ready for production. Can acetal be used in a molded application?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Can Delrin be molded?
If the part is small, the moldmaker may be able to use a MUDD base to cut your tooling costs. One problem with acetal is that it shrinks differently along the flow in the mold than it does across the flow. careful design can minimise the evil effects.
One of the things I do is review designs for molding to minimise moldmaking and molding problems. Let me know if you could use this service.

I would like to take you up on your offer of assistance. How can I e-mail you directly a PDF file of my drawings?

If Insideman can't help.
But I am fairly sure he can.
He is very knowledgable about plastic parts.
I can help you to mold the parts cost effectively.
The downside with Acetal is that thick sections will usually have sink marks. The first rule to remember when considering injection molding. Always try to design your part with a nominal wall thickness. Typical working range (wall thickness) for Acetal is .030 to .120.
I mold quite a bit of Acetal and would be pleased to review your project. I have short run to high production capacity and work in high tolerances if needed (as in Medical).
