Lin's drone housing project had been stalled for three months. As a structural engineer at a drone company in Shenzhen, he was responsible for a new product whose housing required a flatness of 0.05mm. But after switching between three different injection molding partners, none could meet the spec. The first had outdated equipment, producing parts that warped like roof tiles. The second blamed the material, but even switching to imported resin didn't help. The third flatly stated, "This requirement is too strict. We can't do it."

Lin's boss slammed the table at the weekly meeting: "One housing has taken three months. When will the product ever launch?" The pressure was so intense that Lin couldn't sleep, scrolling through injection molding supplier profiles at 3 a.m. A friend working in procurement at BYD recommended Fengchuang Plastics, saying, "They have over 20 Haitai injection molding machines and their own proprietary technology. Go give them a try."

The next day, Lin visited Fengchuang's workshop. Rows of Haitai injection molding machines stood neatly arranged, ranging from 90 to 800 tonnes—covering all his product requirements. When Fengchuang's engineer reviewed his part drawings, instead of quoting immediately, he asked one question: "What tonnage machine were you using before?" Lin said 120 tonnes. The engineer replied, "120 tonnes doesn't leave enough margin for this part. We'll run it on a 250-tonne machine—higher clamping force means less deformation."

Two weeks later, Lin received the first sample batch. He rushed to the measurement equipment, and the flatness data appeared one by one: 0.032mm, 0.028mm, 0.035mm, 0.029mm. All well within 0.05mm. He stared at the numbers for a long time, then sent a WeChat message to Fengchuang's engineer: "How did you do this?" The reply: "One size larger equipment, one layer finer process. That's how."

The drone is now in mass production, with monthly sales exceeding 10,000 units. Lin says, "I tried three molding shops and finally found the answer at Fengchuang. Over 20 branded injection molding machines plus their proprietary technology—that's what brought this project back to life."

Struggling with flatness below 0.05mm after switching three suppliers? Fengchuang's 20 branded injection molding machines and proprietary technology solve deformation problems in one go.
