Manufacturing Process of Plastic Pallet Injection Molds

Plastic pallet injection molds are the core equipment in pallet production, directly determining the precision, strength, and lifespan of the final product. 

As essential tools in modern logistics and warehousing, plastic pallets demand molds with high strength, precision, and durability.

Manufacturing Process of Plastic Pallet Molds

1. Design Phase

3D Modeling & Structural Analysis – Professional software (UG, Pro/E) for 3D modeling, Moldflow for optimizing the injection system

Material Selection – High-quality mold steel (P20, 718H, S136) chosen based on production volume; heavy-duty pallet molds often use HRC48-52 hot-work steel

Parting Line Design – Scientific design ensures smooth demolding and minimizes flash

2. Precision Machining Phase 

CNC Rough Machining – Large gantry machining centers achieve base machining (±0.05mm precision)

Heat Treatment – Vacuum quenching + multiple tempering ensures uniform internal structure

Precision EDM – Mirror-finish EDM machines create complex cavities (Ra 0.2μm surface roughness)

High-Speed Finishing – 5-axis machining centers achieve final precision (±0.01mm for critical areas)

3. Assembly & Testing Phase 

Mold Base Assembly – Standard or reinforced mold bases ensure clamping precision

Ejection System Tuning – Optimized ejector pin layout and stroke for smooth demolding

Trial Testing – Adjusts parameters through test shots until qualified samples are produced

Core Technical Advantages

1.Innovative Structural Design

Multi-point hot runner system reduces material waste

Optimized cooling channels shorten cycle time by 30%+
