HMD 450M8-SPV High-Speed Thin-Wall Injection Molding Machine

The HMD 450M8-SPV operates at the upper boundary of mid-range thin-wall machines, providing 4,500 kN clamping force for applications that exceed the capability of 400T machines. The machine shares the advanced injection platform of the 418T and 428T models, delivering 517 mm/s injection speed, the highest available in the mid-range SPV5 segment. This speed advantage is critical for milk tea cup production where the tall, tapered cup geometry demands rapid fill to prevent freeze-off in the 0.5-0.7mm wall section. All SPV5 engineering features are present: servo-hydraulic drive with high-speed accumulators, strengthened platen, nitride-treated links, alloy metallic tie bars, self-lubrication bushes, and parallel movement hydraulics. The INOVA controller provides comprehensive process control for thin-wall applications requiring tight tolerances and consistent shot-to-shot repeatability.

The 4,500 kN clamping unit features a platen sized between the 428T (1,120 x 1,060 mm) and 480T (1,190 x 1,140 mm) models, with tie bar distance in the 720-760 x 660-710 mm range. This provides ample space for 8-12 cavity milk tea cup mold layouts and 4-8 cavity large container molds. Mold opening stroke is sufficient for the tall core extraction required by milk tea cup geometry (150-180mm cup height plus ejection clearance). Maximum daylight accommodates thick mold stacks with hot runner manifolds and IML mechanisms. Mold thickness range handles both standard and IML-configured tooling. The ejector system provides the force and stroke needed for both pin ejection and stripper plate systems. The strengthened platen design is essential at this tonnage where mold weights of 2,500-4,000 kg generate significant bending moments during clamping.

The HMD 450M8-SPV employs dual 55+55 kW pump motors at 19 MPa system pressure, delivering 110 kW total hydraulic power. The higher pump power compared to smaller SPV5 models provides the flow capacity for the 517 mm/s injection speed through rapid accumulator charging between cycles. Heater power of approximately 27.5 kW across 6 temperature zones manages the larger barrel assembly. Oil tank capacity of 480 liters ensures thermal stability during extended runs. The servo-hydraulic drive reduces energy consumption to approximately 1.0-1.2 kWh/kg. The parallel movement system overlaps plasticizing with clamping, recovering 1.0-2.0 seconds per cycle at this machine size. The regenerated hydraulic circuit minimizes heat generation and component wear. Machine dimensions of approximately 7.1-7.4 x 2.0 x 2.4 meters allow efficient factory floor placement.

At 450T, the HMD 450M8-SPV enters the tonnage range where premium European packaging machines are most dominant. The Netstal Elios 4500 (450T, 900-1,300 mm/s injection speed, 1.4s dry cycle, $600,000+) is the benchmark machine in this class. The Sumitomo Demag El-Exis SP 420 (420T, 1,000 mm/s, $500,000+) and Engel e-speed 450 ($400,000+) are leading alternatives. Against these machines, the HWAMDA offers approximately 35-50 percent of the injection speed but at 15-25 percent of the capital cost. For markets where cycle time is important but not at the absolute minimum achievable by European machines, the HMD 450M8-SPV provides commercially viable thin-wall production at a dramatically lower investment threshold. The turnkey integration with HWAMDA molds and SWITEK IML further improves the value proposition.
