Patent ID: 7833450

Claim:
A manufacturing process for obtaining an object, said object made of a microcrystalline polyamide or having all or part of its outer surface formed from a said microcrystalline polyamide and having a particular surface finish, said process comprising a thermomechanical treatment carried out between the T g (glass transition temperature) and the T m (melting point) of said microcrystalline polyamide, wherein said thermomechanical treatment is chosen from the group consisting of moulding, compression moulding, undermoulding, injection moulding, sheet extrusion/calendering, lamination process, screen printing, thermoforming process, stamping process, in-mould decoration (IMD) process, sintering process, welding process, and wherein the transparency of the microcrystalline polyamide is such that the light transmission at 560 nm on a polished object 1 mm in thickness is greater than 80%.
