Operating from Huangyan, Taizhou—widely recognized as China’s Mould Capital—Taizhou Zhongyue Mould Co., Ltd. is a professional manufacturer specializing in Plastic Logistic and Engineering Moulds. We develop robust tooling solutions for industrial applications such as plastic crates, pallets, manhole chambers, pipe fittings, and electrical enclosures. Our moulds are engineered for continuous high-pressure production environments and built with high-tensile steel to ensure long-term structural stability and reliable performance in heavy-load usage.
From foldable turnover boxes to beer crates and vegetable baskets, our logistics molds focus on high-speed cycling and anti-sticking designs.
Stack & Nest Design: Optimized draft angles for easy demolding and secure stacking.
Reinforced Ribs: Scientific rib design to prevent buckling under load without sink marks.
Cooling: BeCu (Beryllium Copper) inserts in deep ribs for rapid cooling.
We produce large-format molds for single-face, double-face, and grid/solid top pallets (up to 1600x1400mm).
Steel Structure: Thick pre-hardened steel (2738HH / S136) to resist injection pressure deformation.
Gas-Assisted Option: For thick-walled pallet feet/rims to reduce weight and prevent sink marks.
Ejection: Multi-stage ejector systems with synchronized return for large flat surfaces.
Essential for municipal drainage and sewage systems, these molds require extreme durability.
Deep Cavity Molding: Specialized cooling channels for deep, vertical walls (up to 1m depth).
Anti-Warpage: MoldFlow analysis to manage shrinkage on large circular or square chambers.
Surface: Sandblasted or textured finish for concrete pouring compatibility.
Precision molds for PVC/PP/HDPE fittings (Couplings, Elbows, Tees, Valves).
Core Puller Mechanism: Hydraulic cylinder side-action cores for complex geometries.
Beryllium Copper: Extensive use of BeCu in cores to prevent deformation of thin-walled fittings.
Cold Slug Well: Optimized runner design to prevent cold material from entering the cavity.
For meter boxes, distribution cabinets, and waterproof enclosures.
Dimensional Accuracy: Tight tolerance control for screw bosses and sealing grooves.
Overmolding Ready: Options for TPE/TPU gasket overmolding in the same tool.
UV Resistance: Mold design compatible with UV-stabilized polymers.

High-tensile steel and reinforced structural design ensure mold longevity under continuous high-pressure industrial production.
Advanced cooling systems, gas-assist options, and hydraulic core pullers for complex geometries.
Taizhou Zhongyue Mould Co., Ltd. manufactures Plastic Logistic and Engineering Moulds for turnover crates, industrial pallets, storage bins, tool boxes, automotive logistics parts, and heavy-duty transportation containers.
We reinforce structural ribs, optimize bottom support grids, and improve material flow balance to ensure products can withstand heavy stacking and long-distance transportation loads.
Yes. We design molds for industrial pallets and stacking crates with strong structural stability, anti-slip surfaces, and compatibility with automated warehouse systems.
Deformation is usually caused by uneven cooling or insufficient structural reinforcement. We solve this through optimized cooling channels and balanced wall thickness design.
Yes. We can design multi-cavity systems to improve output efficiency and reduce production costs for high-volume logistics products.
We use high-strength mold steel, precision machining, and structural optimization to ensure long-term durability under repeated industrial use conditions.
Backed by 50+ design engineers and 20+ CNC machines, ZHONGYUE provides full DFM reports, MoldFlow analysis, and T1 trial support for your industrial projects. Contact us today for a customized quotation on your next heavy-duty injection mold.
