Important points among process:
1)Our brake drums choose the HT250 as the raw casting materials, the reason why we choose this kind of pearlyte gray iron are its excellent features of good compressive strength, outstanding wear-resisting property, premium heat dispersion and casting ability. As we all know that the quality of each piece brake drum is up to the quality of its semi-finished casting parts, so we already build up a strict raw materials ausit program in order to ensure that each of our brake drums meet the quality standards of our clients.
2)Our brake drums will directly go to the finishing department after they go out from the brake drum casting workshops, and these semi-finished brake drums shall be tested before they go into the finishing workshop, we choose the advanced automatic finishing machines from Japan, in the process of finishing, all dates and requirements are controlled by computers, every side of brake drums will be polished according to the desinged procedures in computers, which will keep our brake drums meet the OE standards.
3)Our brake drums are drilled by full automatic drilling machines, we put our brake drums into the CNC machines, which will automatically finish these brake drums with drills by design procedures, the advantages of this drilling technique is to ensure that the size of drills on each brake drum meet the OE standards.
