The quality requirements for the sprockets in the orders received by our company are high. The castings are subjected to non-destructive testing as a whole, and some areas are inspected according to EN12680-2 Level 2, EN1369 SM1-LM1-AM1， The maximum size of the casting is 2700mm, and the thinnest is 20mm, so controlling the casting to not deform is also a difficult point in production.
This project has been under negotiation since July this year. After the process design, mold making, casting, quality inspection and other steps, through the unremitting efforts of all employees of the company, two sets (4 pieces) were finally delivered to the customer on time by the end of September
