HMD 380M8-SPV High-Speed Thin-Wall Injection Molding Machine

The HMD 380M8-SPV occupies a critical position in the SPV5 series as the go-to machine for yogurt cup and IML margarine container production. At 3,800 kN clamping force, it provides sufficient clamping for 8-16 cavity yogurt cup molds (6g parts, 0.45-0.6mm wall) and 4-8 cavity IML margarine container molds (12g parts). The machine incorporates all SPV5 hallmarks: servo-hydraulic drive with high-speed hydraulic accumulators, strengthened platen with high-rigidity structure, nitride-treated toggle links, alloy metallic tie bars, and self-lubrication bushes. The parallel movement hydraulic system enables simultaneous plasticizing and clamping operations, reducing dry cycle time. The double rod injection cylinder and linear guide injection unit ensure consistent injection speed profiles critical for thin-wall filling. This model is specifically recommended by HWAMDA for IML applications where the SWITEK SW833 automation system (rated for 150-450T machines) integrates directly with the machine.

The 3,800 kN clamping unit features a platen configuration aligned with the 368T model: approximately 1,030 x 1,000 mm platen size and 670 x 640 mm tie bar distance. This provides ample area for 16-cavity yogurt cup mold layouts and 8-cavity margarine container mold footprints. Mold opening stroke of 640 mm provides clearance for both part extraction and IML robot entry. Maximum daylight of approximately 1,310 mm accommodates mold stacks including hot runner manifolds and IML label placement mechanisms. Mold thickness range of 270-670 mm handles both thin standard molds and thick IML-configured tooling. Ejector force of 77 kN with 100mm stroke drives stripper plates and pin ejection systems. The strengthened platen maintains rigidity under the concentrated loads of multi-cavity hot runner manifold plates, ensuring uniform part thickness across all cavities.

The HMD 380M8-SPV employs dual 45+45 kW pump motors operating at 19 MPa system pressure. The 90 kW total pump power provides the hydraulic flow for rapid clamp close-open movements and high-speed injection accumulator charging. The parallel movement system enables charging on fly, recovering 0.5-1.5 seconds per cycle compared to sequential operation. Heater power of approximately 27.5 kW across 6 temperature zones provides precise barrel temperature control. Oil tank capacity of 380 liters maintains thermal stability. The servo-hydraulic drive delivers energy consumption of approximately 1.0-1.2 kWh/kg, representing a 35 percent savings versus conventional hydraulic machines. Machine dimensions of approximately 7.3 x 2.0 x 2.4 meters fit standard factory bay widths. Electrical components include Omron and Schneider industrial-grade devices, with the INOVA controller supporting communication protocols for SWITEK IML system integration.

In the 350-400T IML packaging segment, the HMD 380M8-SPV competes against machines specifically designed for IML thin-wall production. European leaders include the Netstal Elios 4500 (450T, $600,000+, 900-1,300 mm/s injection speed, 1.4s dry cycle), the Engel e-speed 280 ($350,000+, 0.8 kWh/kg verified), and the Arburg Allrounder 720A ($400,000+, ICM capability achieving 0.37mm wall). These machines offer superior technical specifications but at 3-7x the capital cost. Chinese alternatives include the Yizumi P-E 350T ($120,000-250,000) and Haitian Mars V 380T ($55,000-75,000). The HWAMDA advantage is the complete turnkey ecosystem: the machine ships with matched HWAMDA mold, SWITEK IML automation, chiller, loader, and doser, all commissioned together. This single-source approach reduces project timeline by 2-3 months and eliminates integration risk between components from different suppliers.
