Why recently zmie lead time is long for casting parts?

This year China government pay more and special attention to the environmental protection, for some critical factors, especial casting and electroplating industry...the control measures are much stricter than before.many casting foundry and electroplating workshops are being stopped now.

the old method of casting “lost wax casting” has been completely banned. now the allowed method of casting is shell casting. ZMIE need make new mould for some products like CC600 chain, C55 chain, C188 chain...so the production is longer than before. For better environment we living please understanding!
