Three-runner / three-beam rack pallet molds produce standard plastic pallets in sizes such as 1200×1000, 1200×800, and 1300×1100. With three continuous beams at the bottom, they suit rack storage and four-way fork entry, widely used in warehousing, food and beverage, chemicals, pharmaceuticals, and automotive parts. Pallets are typically made of HDPE for impact resistance, low-temperature performance, and reusable circulation. Mold design focuses on beam stiffness, fork opening dimensions, anti-slip teeth, and optional built-in steel tube channels. 718H or 1.2738 steel is recommended, with a 16+ valve gate hot runner system for balanced filling over large projected areas. Overall advantages include high load capacity, rack suitability, and optional steel tube reinforcement.

Nine-leg stackable pallet molds are used to produce lightweight plastic pallets with nine conical legs at the bottom, allowing empty pallets to nest and stack, significantly saving storage and return transport space. They are widely used in light-duty turnover, warehousing, and empty pallet return. Mold design focuses on controlling leg taper and wall thickness uniformity to avoid stress whitening, sink marks at the leg base, and unstable stacking — ensuring smooth nesting, reliable load capacity, and convenient reusable circulation. Overall advantages include lightweight design, nestability, and space saving — ideal for light-duty logistics and turnover.
