Engineering Overview:
Our engineering focus is on the involute tooth profile accuracy and total composite error control. We implement advanced shrinkage compensation in the mold design stage to maintain perfect concentricity and prevent the pitch deviations typically found in standard molded gears.
Technical Specifications & DFM Insights:
The mold inserts are finished via sub-micron CNC machining to meet DIN 3967 / AGMA 10 standards. We utilize a balanced multi-point gating system to ensure uniform material flow, which minimizes internal stress and significantly reduces axial runout for smooth gear engagement.
Why JST Mould?
JST Mould bridges the gap between plastic molding and high-precision gear manufacturing. By combining material science with rigorous gear-metrology (CMM verification), we deliver transmission components that meet the durability standards of global Tier-1 automotive and industrial clients.
Application Fields:
Automotive actuators, precision office automation, medical robotics, and high-end consumer appliances.
