HX(*) 258 Injection Molding Machines

Description

HX 258 injection forming machines adopt "direct-lock” two-platen clamping mechanism and a newly-developed AC servo motor to update its various working performance. The new AC servo motor enables remarkably smooth clamping stroke with highly responsive acceleration and deceleration. Besides, the motor realizes a substantially reliable and consistent high-cycle molding. For HX 258 injection molding machine, the combination of "direct-lock” hybrid clamping unit and all-electrical injection unit contributes to the energy-saving and minimizing the hydraulic fluid utilization.

Advantages of HX 258 Injection Forming Machine

1. New Molding Clamping Structure

Internal rolling molding-lock structure is featured by five curved supporting points and crank mechanism. Its connecting rods and molds are strengthened into cast structure by FEA (Finite Element Analysis), effectively reducing stress and deformation, and improving rigidity and precision.

2. New Power Structure

To optimize the energy utilization for HX 258 injection forming machine, a brand-new power structure is applied. This new structure is constituted by servo motor, servo driver, pressure sensor, rotary encoder, gear pump, etc.
