STF HMB125 Motor for Injection Molding Machine

The TH-STF125 (HMB125) Motor for Shield Machines represents a culmination of years of expertise in hydrostatic balance technology, embodied in the TH-STF series. This motor boasts a robust casing and enhanced internal dynamic component capacity, significantly minimizing internal friction and heat through its innovative design. The hydrostatic balance established between the piston, connecting rod, and eccentric sets effectively reduces friction and contact pressure, leading to lower friction losses during operation. As a result, the TH-STF series achieves impressive mechanical efficiency and starting torque, with efficiency levels reaching up to 90% at startup. Additionally, the hydrostatic balance shaft distributor ensures optimal sealing and minimal leakage, allowing for continuous operation under high pressure, with a maximum capacity of 29 MPa. The use of specialized materials and advanced seal structures further enhances volumetric efficiency and extends the service life of the motor, making it an ideal replacement for STAFFA motors with compatible mounting and performance characteristics.
