HMD 280M8-SPV High-Speed Thin-Wall Injection Molding Machine

The HMD 280M8-SPV occupies a specialized niche in the SPV5 lineup, providing 2,800 kN clamping force specifically calibrated for high-cavitation small-part production. The machine incorporates all hallmark SPV5 features: servo-hydraulic drive with high-speed hydraulic accumulators, strengthened platen with high-rigidity structure for thin-wall applications, nitride-treated links, alloy metallic tie bars, and self-lubrication steel and copper bushes. The parallel movement hydraulic system enables charging on fly, while the double rod injection cylinder and linear guide injection unit minimize friction for consistent high-speed injection. The INOVA controller from Italy provides the precision timing required for managing 16-32 cavity filling balance. The machine is specifically referenced in HWAMDA's architecture as the SPV-280 sauce cup machine, indicating its primary design optimization for this high-volume application.

The 2,800 kN clamping system provides additional force margin compared to the 270T model, important when running higher cavity counts that increase projected area. The platen dimensions and tie bar spacing are designed to accommodate sauce cup molds with up to 32 cavities arranged in optimized patterns. The mold opening stroke provides clearance for the stripper-plus-robot demoulding sequence, where the stripper plate first breaks parts free from cores, then the SWITEK robot extracts parts from the mold area. Maximum daylight accommodates mold stacks typical of multi-cavity sauce cup tooling. Ejector force of 77 kN drives the stripper plate mechanism with sufficient force for simultaneous ejection of all cavities. The strengthened platen maintains flatness under the concentrated loads of high-cavitation hot runner manifold plates, preventing uneven clamping that could cause flash on individual cavities.

The HMD 280M8-SPV uses a dual pump motor configuration operating at 17.5 MPa system pressure, providing the hydraulic flow needed for rapid cycle times. The dual-pump parallel movement system is particularly valuable for sauce cup production, where cycle times of 3-4 seconds leave minimal time for sequential hydraulic operations. By executing plasticizing and mold closing movements simultaneously, the system recovers 0.5-1.0 seconds per cycle that would otherwise be lost. The servo-hydraulic drive reduces energy consumption to approximately 1.0-1.2 kWh/kg processed resin, compared to 1.4-1.6 kWh/kg for standard hydraulic machines. With sauce cups at only 3g each, the energy cost per unit is negligible (approximately $0.0003-0.0005), but energy savings compound significantly over annual production volumes exceeding 200 million units. Electrical components from Omron and Schneider ensure industrial-grade control reliability.

The HMD 280M8-SPV is positioned against Chinese mid-range machines like the Haitian Mars V series and Yizumi P-E series in the 250-300T range, as well as premium options from European manufacturers. Haitian Mars V machines in this tonnage range ($45,000-65,000) offer general-purpose servo-hydraulic performance but lack the SPV5's specialized thin-wall features including strengthened platens, high-speed accumulators, and purpose-built parallel movement systems. European alternatives like the Engel e-speed 280 ($350,000+) deliver higher injection speeds (up to 800 mm/s) and lower energy consumption (0.8 kWh/kg verified) but at significantly higher capital cost. The HWAMDA differentiator is the single-source turnkey approach: machine, 32-cavity sauce cup mold, robot, chiller, and loader designed and supplied together, with integrated commissioning that guarantees performance from day one.
