You never can say we don’t have problems in supplying chain, whatever it is about the quality, or delivery, or you are a large company or small one. The key point is whether you always have a good plan B when there is a deadlock with plan A.
Below is real case study show how we could be flexibility on solving the problems.
Gearbox housing used in metro sliding door
very high geometric tolerance and enough strength to transmit the power from motor to door opener, with long-lasting life and economic way.
·Using a aluminum housing to instead zinc’s,lighted the weight significantly.
·Adding some precision machining on the critical dimensions to instead casting out directly.keeping high-quality stably.
Part name: gearbox housing
Weight: 220 grams
Application: metro sliding door
Exported country: Japan
Problem:
Client had the problems on the precision tolerance and the over high cost . They once used zinc as the material for casting, and critical dimensions casted out directly.
Solution:
·Utilizing the aluminum as the casting material, lighted 2/3 weight.
·Adding CNC precision machining on the critical dimension, to keep high-quality stably.
·To validate our process, we made some prototypes with aluminum profile machined
Benefit:
·Saving the overall cost of part
·Got the tight tolerances guaranteed
·Made a real validation before a big amount of tooling investment
