Realistic Tolerances for Molded Plastic Parts
Realistic Tolerances for Molded Plastic Parts
(OP)
Hello,
I am checking tolerances on plastic and elastomeric parts. Is +/-.004 inches a REALISTIC tolerance for molded silicone? The mold can easily be machined to those tolerances, but what can I expect for the final product?
Also, can I also hold those tolerances for molded thermoplastic and thermoset parts?
What can I typically expect from industry?
Thanks in advance!!!

My part is a thin frame about 1" x .6" with a square cross sectional thickness of about 0.75". It sounds like I may fall within the .005" shrinkage. We just need to get the part prototyped before production. Thanks again.

Does anyone have experience with molding silicone and expected tolerances for the a thin frame about 1" x .6" with a square cross sectional thickness of about 0.75"?
