Rotary Machine for Gearbox Connector Overmolding

Challenge

Connector components inside automotive gearboxes are small overmolded parts in a special material, requiring high injection speed and a barrel made for that material.

Machine

Taifu vertical rotary table injection molding machine with high-speed injection.

Solution

Injection speed of 218 mm/s (higher on request) and a Ø28 mm screw with a custom-made barrel for the special material; otherwise the machine is standard. The mold uses a hot runner plate, with thermocouples embedded in both the fixed and moving mold bases to monitor mold temperature continuously so the water temperature can be adjusted.

Result

Keeping the mold within the right temperature range improves part quality and extends mold life.
