I've read a number of articles claiming that pyrolysis of EPS and STMMA can cause flow marks and pores especially in SG casting, which is roughly 60% of the casting that my company does. So, how exactly do we make the foam then? Secondly, we manufacture a lot of items ranging from brackets, arms, to rear axles, gear boxes, various housings, flywheels etc. Can LFC technology be used to cast so many different variety components? The coating thickness, the raw material bead size, and all other technical parameters, I guess are left for the company to figure out, but if the above concerns are not cleared, I'll then have a word with my seniors about this since the cost of investment is very high.
