Mr. Liu's Taobao shop had entered peak season, but his new product was stuck at the molding stage.

Based in Hangzhou, Mr. Liu runs a mother and baby products business. His newly designed baby spoon required two-shot injection molding, combining soft and rigid materials. The previous molding shop had spent 35 days making the mold. When they ran the trial, the bond between the soft and rigid materials failed – the spoon delaminated with just a bit of pressure. Reworking the mold took another 10 days, but the problem remained. The shop's technician said, "It might be a design problem," and suggested changing the product structure.

Mr. Liu didn't dare change the design. He had already invested 120,000 RMB in pre-launch marketing. Pre-sale links were live, with a promised shipping date of July 15th. Now it was nearly the end of June, and he still didn't have a single sample. His customer service team received dozens of order inquiries every day. Mr. Liu was so stressed that stress blisters appeared on his lips.

A friend in procurement told him that Fengchuang Plastics specialized in two-shot molding. Mr. Liu called that same day and sent over the drawings. After reviewing them, a Fengchuang engineer said, "The design is fine. The problem is the mold. The bonding surface between the two materials needs micro-texturing."

Fengchuang's solution was this: add micrometer‑scale凹凸 texture on the bonding surface of the rigid material mold, so that when the soft material is injected, it flows into the texture and forms a mechanical lock – not relying on chemical adhesion. This solution required no change to the product design, only to the mold surface treatment.

Seven days later, Mr. Liu received 12 samples. He pulled them, bit them, twisted them hard – the soft and rigid materials stayed firmly bonded, with no sign of delamination. Mr. Liu immediately took a video and sent it to his contract manufacturer, saying, "Make them exactly like this."

Today, that baby spoon has become a bestseller on his shop, selling over 20,000 units per month. Mr. Liu says, "From now on, I'm bringing all my new product molds to Fengchuang. No need to look elsewhere."
