HXM Servo Energy-Saving

HX(*)258-I/870

The HXM 258-I/870 is a balanced and efficient servo injection molding machine built for medium-sized plastic product manufacturing. By combining a rapid-response servo-hydraulic drive with precise pressure and flow control, it delivers high molding repeatability and reduced cycle times for industrial, packaging, and consumer goods. Key Technical Specifications: Clamping Force: 2580 kN Injection Capacity: 381 to 678 cm³ (depending on screw choice) Screw Diameters: 45 mm, 50 mm, 55 mm, or 60 mm Injection Performance: 129 to 229 MPa pressure with plasticizing up to 40 g/s Power System: 30 kW servo motor and 18.1 kW heating capacity Mold Dimensions: 560 mm opening stroke; 200–610 mm mold height range Tie-bar Spacing: 580 × 540 mm Physical Footprint: 5.76 × 1.44 × 2.15 meters; ~7.4-ton weight Specialized Features: 280-liter oil tank, 17.5 MPa pump pressure, and an optimized hydraulic system for substantial energy savings and consistent output.
