Is there any additives which improves the surface of the plastic?
Is there any additives which improves the surface of the plastic?
(OP)
I am now working at the company which specialized in processing the engineering plastic that mainly uses the nylon 6, nylon 6,6. and every time I make the plastic with the extruders with a certain ratio of the ingredients, sometimes the plastic I made meets the standard of the physical or mechanical properties, but it is too hard to improve the surface of them. Whenever I do the injection molding to make the specimen to test the mechanical properties, the surface of them is really really bad relative to the other competitors. Are there any guys who can give me some advice to improve the surface?
Regardless of the additive or base resins, I hope I can get some precious advices from you guys.
Thank you in advance.

If the extrusion grade is of low MFI you may have difficulty anyway.
Look up "processing conditions PA6 PA66". Google should give you plenty of hits.

You will find that PA6 has better surface finish than PA66 primary because it flows better (lower viscosity). Additives like glass fiber or minerals will reduce surface finish. Your finish will never be better than the mold surface finish.
