1200×1000mm double-face blow molded pallet mold project (with internal steel reinforcement)

PAIN POINTS

Chemical industry pallets carry corrosive materials. The old mold's pallet showed insufficient weld strength at the top-bottom sheet fusion line, delaminating under 1200kg dynamic load. Wall thickness deviation reached ±1.5mm, causing stress concentration and cracking over time. Internal steel pipe positioning deviation affected load uniformity.

MOTEK SOLUTION

• Used 7075 aviation aluminum forged cavities with zoned independent temperature control, controlling wall thickness deviation within ±0.5mm.
• Optimized parting line and blow pin position, improving top-bottom weld strength by 40% and passing 1500kg dynamic load test.
• Designed steel pipe positioning inserts and anti-shift structure, ensuring internal pipe position accuracy of ±0.8mm.

"motek's blow molded pallet mold helped our product pass all EN ISO 8611 tests on the first try. Our chemical clients are very satisfied with the load life."

North American Export Logistics Provider

1100×1100mm 9-leg lightweight blow molded pallet mold project

PAIN POINTS

Export pallets require both lightweight design and load capacity. The old mold produced pallets that were too heavy, driving up sea freight costs. The 9-leg structure made wall thickness difficult to control during blow molding, often causing local thin or thick spots, leading to uneven load and cosmetic defects.

MOTEK SOLUTION

• Achieved 22% weight reduction through parison program control and local cavity thinning while maintaining load capacity.
• Designed dedicated leg cooling inserts and blow pin timing control, eliminating leg wall thickness deviation and reducing cycle time by 18%.
• Used 6061 aluminum cavities with precision guiding system, ensuring deformation-free operation under long-term production.

"motek's blow molded pallet mold helped us achieve our lightweighting goal, saving over $150,000 annually in sea freight."
