>>Highlights 01

「Clamping unit」

• High Rigid Structure: Optimized platen, frame and injection unit design reduce platen surface deformation to below 0.03 mm.
• Separate Supports for Crosshead Guide Rod: The structure minimizes the impact of tail platen deformation on the crosshead, enhancing stability.
• Independent Reinforcement of Movable and Fixed Platens: The separate supports and optimized thermal conduction maintain platen parallelism and prevent thermal deformation.
• Precise Clamping Force Control: Encoder-based mold adjustment ensures accuracy within 3.5 kN.
• Ultra-High Guiding Accuracy: Liner guide rail design achieves 0.01mm straightness.

「Injection unit」

• Double-Ball-Screw Injection Unit Technology: This technology evenly distributes axial load, eliminating nozzle overtrumping force for stable injection.
• Smart Direct Control Technology: 0.125ms ultra-fast response ensures excellent motion precision.

「Cleaning design」

• The design features all-electric configuration with zero hydraulic oil pollution, compatible with various cleanroom levels and specialized for medical application.
