Professional Plastic Tray Mold Manufacturing | Rich Experience & Stable Quality

Plastic tray molds belong to large-size, heavy-load industrial injection molds, which have far higher manufacturing standards than ordinary daily commodity molds. During mass production, plastic trays are prone to typical defects including warpage, shrinkage dents, load-bearing cracking, uneven cooling and insufficient air venting. Therefore, professional structural design, reliable steel selection and high-precision machining are essential to qualify stable tray mold production.

As a professional custom injection mold manufacturer based in Taizhou — China’s mold capital, Hongmei Mould specializes in the design and manufacturing of high-performance plastic tray molds. With solid technical accumulation and mature production systems, we successfully complete more than 50 sets of tray molds annually. Our rich project experience allows us to precisely optimize wall thickness, stiffener distribution, cooling layout and exhaust structure, completely solving common molding defects of large plastic trays.

We adopt targeted structural optimization for every tray mold to balance cooling uniformity and structural strength. Symmetrical rib design, reasonable shrinkage rate reservation and independent circulating water channels effectively prevent product warping, surface sinking and cracking. Meanwhile, optimized demolding slope and balanced ejection system ensure smooth demolding without pulling white or deformation, enabling finished plastic trays to meet strict industrial load-bearing and flatness requirements.

Hongmei Mould delivers reliable one-stop mold customization services, covering product structure optimization, mold design, high-precision CNC machining, mold trial testing and after-sales support. All tray molds adopt thickened and reinforced mold bases, paired with high-grade mold steel such as 718H and S136. Every mold undergoes full inspection and repeated mold trials before delivery to ensure stable, consistent and long-term mass production performance.

We strictly implement standardized quality control standards throughout the whole production process. Our stable production lead time is 25–35 working days. With years of experience serving global clients, we have supplied high-quality custom tray mold solutions for manufacturers worldwide, gaining consistent trust and praise for our professional craftsmanship and reliable delivery.
