Xiao Liu is a production supervisor at a lighting company in Foshan. One of their LED lamp housings requires gate trimming. The problem with manual trimming was obvious: each worker had a different technique – some cut too deep, others too shallow – resulting in inconsistent parts. Customers complained multiple times, saying, "The gate mark on your product is too visible. When installed, we can see a white spot on the lamp."

Xiao Liu tried using fixtures to guide workers to cut at fixed positions. The results improved but were still far from perfect. The issue was that workers' hands shook, and controlling the cutting force was difficult – either they cut too deep, leaving a dent, or too shallow, leaving a protrusion. Xiao Liu's management burden kept growing, as he had to spend hours each day inspecting gate quality. His boss gave him a final warning: "If this isn't fixed this month, you're out."

The pressure was so intense that Xiao Liu couldn't sleep and his hair was falling out in clumps. His wife, worried about him, saw a video of Fengchuang Plastics' automated workshop on Douyin (TikTok) and showed it to him. In the video, a robotic arm removed a part and transferred it directly to a trimming station. A pneumatic cutter made a clean click – the gate mark was so smooth it looked as if it had never existed. The next day, Xiao Liu contacted Fengchuang.

A Fengchuang engineer reviewed Xiao Liu's product and said, "This gate can be trimmed using a pneumatic cutter mounted on a robotic arm. The cutting angle and force can be precisely controlled – far more stable than a human hand." Xiao Liu asked, "What yield can you achieve?" The reply: "For gate trimming, we have never seen a defect caused by our robotic arms."

Xiao Liu placed the order for the lamp housings with Fengchuang. When the first batch arrived, he randomly selected 50 parts and inspected the gate areas with a magnifying glass. Every single cut was perfectly smooth and uniform. He took photos and sent them to the customer. The customer replied, "This is the best batch you've ever delivered." Xiao Liu has now moved all of his company's products that require gate trimming to Fengchuang. He says, "Fengchuang's robotic arm saved my job – and my hair."

Manual gate trimming leaving uneven edges and drawing repeated complaints? Fengchuang's robotic arm delivers precision trimming, making gate marks disappear completely.
