Old Chen makes home appliance parts in Foshan. An air fryer panel he produced had two prominent weld lines, and the customer rejected two batches, costing him over a hundred thousand yuan. He approached several injection molding shops. Some suggested changing the gate location, others recommended raising the mold temperature, and a few proposed switching materials. They tried everything, but the weld lines went from "very obvious" to "still noticeable" – none completely solved the problem.

While searching online for articles on injection molding processes, Old Chen came across a technical post by Fengchuang Plastics. It analyzed in detail the formation mechanism of weld lines and offered solutions. The post wasn't an ad – it was solid technical content, with a contact method at the end. Old Chen felt this company had real technical depth and sent them the drawings.

Fengchuang's engineer called back the same day and asked Old Chen one question: "What brand of injection molding machine are you using right now?" Old Chen said it was a small domestic brand. The Fengchuang engineer replied, "Try switching machines. We use all Haitian machines – their pressure and speed response are much faster than smaller brands, which allows us to implement our patented 'pulse injection' process." Old Chen was skeptical but decided to give it a try.

Fourteen days later, the first batch of panels arrived at Old Chen's warehouse. He held them under a high-intensity light, turning them over and over, inspecting them more than a dozen times. The weld lines were gone. Still not fully convinced, he took three samples to the customer, who examined them with a magnifying glass and nodded: "This batch is acceptable." Old Chen immediately called Fengchuang: "Your proprietary technology really isn't just talk. All future orders for this part are going to you."

Now Old Chen has placed all his home appliance panel orders with Fengchuang. He says, "Same material, same mold – but when it runs on Fengchuang's machines, the result is different. Over 20 branded injection molding machines plus their proprietary technology – that combination is unmatched."

Persistent weld lines causing customer rejections? Fengchuang's proprietary technology plus branded injection molding machines eliminate surface defects completely.
