Stackable round stool mold project (seat + legs one-piece molding)

PAIN POINTS

The old mold produced visible sink marks at the seat center due to uneven cooling, causing high cosmetic defect rates. The leg-to-seat joint had insufficient strength, cracking under 150kg static load. Stacking was unstable due to leg angle deviation, wasting transport space.

MOTEK SOLUTION

• Designed conformal cooling channels at seat center, eliminating sink marks and achieving SPI A2 surface.
• Used FEA to optimize wall thickness gradient at leg-seat transition, increasing static load to 200kg without cracking.
• Used high-precision slider core-pulling system to control leg angle accuracy ±0.05°, reducing stack height by 30%.

"motek's stool mold helped our product pass EN 12520 on the first try, significantly reducing stacking and transport costs."

Thickened outdoor square stool mold project (with anti-slip foot pad slots)

PAIN POINTS

The outdoor square stool uses thickened UV-resistant PP. The old mold had low cooling efficiency with a 60-second cycle. Anti-slip foot pad slots showed scuffing due to insufficient draft angle. Sink marks at seat rib roots affected appearance and load capacity.

MOTEK SOLUTION

• Combined beryllium copper inserts with high-thermal-conductivity steel, reducing cooling time from 25s to 15s.
• Optimized foot pad slot draft angles and ejection system to eliminate scuffing and whitening defects.
• Used inserts at rib roots for accelerated cooling, eliminating sink marks and meeting outdoor-grade appearance requirements.

"motek's mold increased our outdoor stool capacity by 30% and passed UV testing on the first try. Our client is very satisfied."
