Mr. Wang owns a medical device company in Suzhou. One of his patient monitor housings had been in production at another injection molding shop for three months, with scrap rates consistently between 8% and 12%. The main problem was inconsistent part removal by operators: some used too much force and deformed the part, while others had oily or dirty hands that contaminated the surface. The worst incident: an operator forgot to insert a metal insert, ruining an entire mold's worth of parts and causing a loss of over 20,000 RMB.

Mr. Wang raised the issue with that shop many times. Their answer was always, "I'll remind the workers to be more careful." But "more careful" didn't solve the problem. His project had already been overdue for three customer deadlines. If he couldn't deliver acceptable parts soon, the order would be canceled. He couldn't sleep, scrolling through his phone at 3 a.m. looking for suppliers. A friend with over a decade of experience in medical devices recommended Fengchuang Plastics, saying, "Their workshop is full of robotic arms. People just push buttons. Go see for yourself."

The next day, Mr. Wang visited Fengchuang's workshop. What he saw was completely different from the other shop: no workers crouching next to injection molding machines to remove parts. Instead, rows of six‑axis robotic arms precisely reached into the molds, extracted the finished parts, and placed them onto conveyors. The entire process was as steady as a clock. A Fengchuang engineer told him, "Our robotic arms have programmed pick‑force, angle, and speed. Every cycle is identical – no variation due to fatigue or mood."

Mr. Wang moved the monitor housing order to Fengchuang. The first batch of 100,000 units was completed with a scrap rate of just 0.3% – and that 0.3% was due to raw material batch issues, not part removal. When Mr. Wang's customer received the parts and did a sample inspection, the pass rate was 100%. The customer's quality team said, "We don't even need to inspect this batch – just put it straight into inventory." That customer has since transferred orders for three other products to Fengchuang. Mr. Wang says, "The robotic arm doesn't just replace human labor – it replaces human inconsistency."

High scrap rate from manual part removal? Fengchuang's robotic automated loading and unloading makes every shot as perfect as the last.
