HMD 400M8-SPV High-Speed Thin-Wall Injection Molding Machine

The HMD 400M8-SPV stands out in the SPV5 lineup for its combination of substantial clamping force (4,000 kN) with the largest injection unit in the mid-range series (918-1,078 cm3). This configuration enables high-cavity-count production of yogurt cups and medium food containers without the step-up to the 450-480T machines designed for larger applications. The machine employs all SPV5 technologies: servo-hydraulic drive with high-speed accumulators, strengthened platen with high-rigidity structure, nitride-treated links, alloy metallic tie bars, self-lubrication bushes, double rod injection cylinder, and linear guide injection unit. The Italy-made INOVA controller with 10-inch LED provides real-time process monitoring including injection pressure curves, speed profiles, and cushion position tracking. The parallel movement hydraulic system enables charging on fly for minimal dry cycle time.

The 4,000 kN clamping unit features a 1,080 x 1,060 mm platen with 720 x 700 mm tie bar distance, providing generous space for multi-cavity molds. Mold opening stroke is 720mm with maximum daylight of 1,390 mm. Mold thickness range of 270-670 mm accommodates thin standard molds through thick hot runner tooling with IML mechanisms. Ejector stroke is 100mm with 77 kN force. The 720 x 700 mm tie bar spacing is particularly important for 16-cavity yogurt cup mold layouts, where cavities are typically arranged in 4x4 grids requiring precise alignment within the tie bar envelope. The strengthened platen design distributes the 4,000 kN clamping force uniformly across this large mold surface, preventing the platen deflection that causes flash on edge cavities. Alloy metallic tie bars maintain alignment stability through millions of high-speed cycles.

The HMD 400M8-SPV uses dual 55+55 kW pump motors operating at 17.5 MPa system pressure, delivering 110 kW total hydraulic power. This is a significant step up from the 45+45 kW systems on the 350-380T models, providing the flow capacity needed for rapid accumulator charging and fast clamp movements at 400T clamping force. Heater power is 31.7 kW across 6 temperature zones, matched to the larger barrel and screw assembly. Oil tank capacity is 380 liters. Machine dimensions are 7.7 x 2.0 x 2.4 meters. The servo-hydraulic drive achieves energy consumption of approximately 1.0-1.2 kWh/kg. The parallel movement system is especially impactful on this machine, where the larger injection unit requires more plasticizing time that can be overlapped with clamping operations. Omron and Schneider electrical components provide industrial-grade reliability.

At 400T, the HMD 400M8-SPV competes directly with established thin-wall packaging machines. Netstal Elios 4500 (450T, $600,000+) offers 900-1,300 mm/s injection speed and 1.4s dry cycle. Engel e-speed at this tonnage ($350,000+) delivers sub-2-second cycles. Sumitomo Demag El-Exis SP 420 (420T, $500,000+) achieves 1,000 mm/s injection with 25ms acceleration to 800 mm/s. These European machines provide approximately 2-3x the injection speed of the HWAMDA but at 3-6x the capital cost. Chinese mid-range alternatives like Haitian Mars V 400T ($60,000-80,000) offer competitive pricing but lack the SPV5's dedicated thin-wall features. The HMD 400M8-SPV uniquely combines competitive thin-wall performance with turnkey integration, making it the value leader for manufacturers targeting 16-cavity yogurt cup or 8-cavity food container production.
