"feasible" True Position Tolerance for bosses on an Automotive Plastic Part

From: ------

Comments

Dear Fellows, Relying on your expertise, wonder If you can advise me what's realistic to expect for a Positional Tolerance Call-out on an Automotive Interior Plastic Part, made out of Thermoplastics, i.e. PP with Fiber Glass content. I have a Floor console plastic part full off such call-outs at MMC restricting location tolerance zone for a boss to a max 0.8 mm dia. cylinder ("bonus granted/applied already when hole is at LMC), in other words, center of actual feature (boss) axis to remain within 0.8 mm dia. "theoretical" cylinder . Thanks for feedback and Good day!
