After 3 rounds of technical confirmation, we finalized the contract on June 15, 2024. The customer initially required standard aluminum oxide flap discs, but later requested a zirconia alumina blend for higher durability in stainless steel grinding. Our R&D team adjusted the formula within 7 days and provided samples for validation. After passing their on-site performance tests, we delivered 50,000 units ahead of schedule, earning positive feedback on wear resistance and consistency.
