HMD 270M8-SPV High-Speed Thin-Wall Injection Molding Machine

The HMD 270M8-SPV combines HWAMDA's proven SPV5 platform technology in the most compact configuration available. The machine uses a servo-hydraulic drive system with high-speed hydraulic accumulators for parallel movement of charging on fly, drastically shortening cycle time for thin-wall products. Key design features include a strengthened platen with high-rigidity structure optimized for thin-wall applications, nitride-treated links with enhanced robustness and stability, alloy metallic tie bars with enhanced strength for extended lifespan, and self-lubrication steel and copper bushes for sustained high-speed performance. The injection unit incorporates a double rod injection cylinder for balanced force distribution, linear guides to minimize friction during high-speed injection, and infrared heating bands for improved plasticizing capacity. The Italy-made INOVA controller with 10-inch color LED screen delivers precision and fast reaction time for thin-wall process control.

The clamping unit delivers 2,700 kN force through HWAMDA's optimized toggle mechanism with nitride-treated links. Platen size is 860 x 850 mm with tie bar distance of 580 x 570 mm, defining the maximum mold size. Mold opening stroke is 560 mm with maximum daylight of 1,160 mm. The machine accepts mold thicknesses from 220 mm to 600 mm, accommodating a range of thin-wall mold configurations from simple cold runner molds to complex multi-cavity hot runner tooling. Ejector stroke is 160 mm with 77 kN ejector force, suitable for stripper plate and mechanical ejection systems used in high-cavitation thin-wall molds. The strengthened platen design distributes clamping force uniformly across the mold surface, preventing deflection that could cause flash or dimensional variation in thin-wall parts. Alloy metallic tie bars with enhanced strength provide the rigidity needed for sustained high-speed operation.

The HMD 270M8-SPV employs a dual pump motor configuration rated at 37+37 kW, operating at 17.5 MPa hydraulic system pressure. This dual-pump design enables the parallel movement capability that distinguishes the SPV5 series: one pump handles clamping while the other manages injection preparation, significantly reducing dry cycle time. Heater power is 22.5 kW across 6 temperature control zones for precise barrel temperature management. The oil tank capacity is 380 liters. The servo-hydraulic drive provides energy savings of approximately 35 percent compared to conventional hydraulic systems, consuming approximately 1.0-1.2 kWh/kg. The regenerated hydraulic system minimizes overload on mechanical structures and hydraulic motor, heightening stability and extending machine lifespan. Electrical components include Omron contactors and Schneider limit switches for industrial-grade reliability.

In the 270-300T thin-wall segment, the HMD 270M8-SPV competes primarily on value and turnkey integration. European machines in this class (Engel e-speed 280 at $350,000+, Netstal Elion at $300,000+) offer higher injection speeds (up to 800-1,200 mm/s) and lower energy consumption (0.8-1.0 kWh/kg) but at 3-5x the capital cost. Chinese mid-range competitors like the Haitian Mars V 270T ($45,000-65,000) offer competitive pricing but lack the specialized thin-wall features (strengthened platen, parallel movement hydraulics, high-speed accumulator) that the SPV5 series provides. The HWAMDA advantage lies in single-source turnkey capability: machine, mold, IML automation, and auxiliary equipment from one supplier with integrated commissioning and after-sales support. This eliminates the integration risk and finger-pointing between multiple suppliers that commonly delays thin-wall production line startups.
