1800mm water-ballasted traffic barrier mold project (MASH TL-2 certified)

PAIN POINTS

Water-ballasted barriers must withstand high-speed vehicle impact while maintaining structural integrity. The old mold's unstable parison control caused wall thickness deviation of ±1.5mm, rupturing under MASH TL-2 impact tests. Uneven sealing surfaces in ballast chambers caused leakage and unstable center of gravity after filling. Uneven cooling caused depressions on reflective film surfaces, affecting nighttime visibility.

MOTEK SOLUTION

• Used 7075 aviation aluminum forged cavities with precise parison program control, controlling wall thickness deviation within ±0.5mm.
• Designed dedicated sealing surface cooling inserts for ballast chamber, ensuring flatness ≤0.5mm and zero leakage.
• Optimized cooling channels at reflective film surface, eliminating depressions and ensuring flat film adhesion.

"motek's barrier mold helped our product pass MASH TL-2 impact testing on the first try. Our clients are very satisfied with the structural strength."

North American Municipal Engineering Equipment Distributor

1200mm folding municipal barrier mold project (hinge + handle integrated molding)

PAIN POINTS

Folding barriers require frequent deployment and storage. The old mold's hinge area showed stress concentration due to uneven blow-molded wall thickness, cracking before 5,000 folding cycles. The handle-to-body joint had insufficient strength, breaking during transport. Low cooling efficiency resulted in a 70-second cycle.

MOTEK SOLUTION

• Used dedicated inserts at hinge area with localized parison thickening, extending folding life to 20,000 cycles.
• Optimized handle-to-body transition structure, passing 50kg pull test without breakage.
• Designed zoned cooling channels for the barrier body, reducing cycle time from 70s to 57s.

"motek's folding barrier mold increased our product's folding life by 4x and capacity by 18%. Our clients are very satisfied."
