The SM-NTP-DMZ III Two-Platen extends Chen Hsong’s multi-material platform to larger parts requiring higher clamping force. It carries the same independent rotary platen lineage and multi-material control experience as the DM III series: an independent rotary platen on a high-rigidity alloy steel base, with clearance of 0.15mm or less, more than twice the precision of the industry average (0.3–0.5mm), and servo-driven positional accuracy of ±0.005°. A patented toggle-brake clamping mechanism delivers balanced, rapid, shock-free, and silent clamping. The two-platen design provides larger mold space, longer opening stroke, and greater mold capacity for bigger multi-material molds.
Modular injection system configurable with three injection structures (horizontal, vertical, and side-mounted) using flexible H/L/V arrangements and 340–1040 injection units for multi-material production from 550 to 750 tonnes. e-Drive™ electric plasticising is standard, saving up to 30% power versus hydraulic and enabling synchronous melt with valve-gate or shut-off-nozzle molds. The machine frame is rigidity-reinforced with an optimised structure for higher load capacity and minimal deformation during operation. OPC-UA connectivity is standard. Built for large automotive components, industrial equipment, and multi-material parts that exceed toggle clamping range.
Both are multi-material machines built around a servo-driven rotary platen, but they differ in structure and range.
The DM III uses toggle (three-platen) clamping from 168 to 568 tonnes with main and auxiliary injection units in a parallel arrangement, 4 patented rotary platen technologies, and ±0.2% injection accuracy.
The SM-NTP-DMZ III uses two-platen clamping from 550 to 750 tonnes in a back-loading layout, with an independent rotary platen positioned to ±0.005° by servo motor and optical encoder, and a patented toggle-brake mechanism providing larger mold space, longer opening stroke, and a more compact footprint.
Choose the DM III for standard multi-material production up to 568 tonnes; choose the DMZ III Two-Platen for larger parts, heavier molds, or when you need two-platen mold space in a compact back-loading machine.
Two-platen clamping provides larger mold space relative to machine footprint, which is critical for large multi-material molds with rotary platens.
The longer opening stroke accommodates deeper parts, and the optimised ergonomic take-out platform makes part removal and automation integration easier. For multi-material applications above 500 tonnes, two-platen is often the preferred architecture because it avoids the longer machine lengths associated with large toggle designs.
Chen Hsong offers two-platen multi-material machines in two layouts: the back-loading SM-NTP-DMZ III from 550 to 750 tonnes, and the parallel-unit SM-TP-DM III from 750 to 1900 tonnes (/injection-molding-machines/dm-iii-two-platen) for parts beyond this machine’s range.
The DMZ III Two-Platen is designed for large multi-material parts up to 750 tonnes: automotive headlight and tail-light assemblies, large appliance panels, industrial equipment housings, and any multi-colour or multi-material application that requires clamping force above 500 tonnes or large mold space.
Rotary table load capacity up to 5 tonnes supports heavy multi-material mold assemblies, with three or more materials available via optional multi-station turntables. For parts above 750 tonnes, the SM-TP-DM III Two-Platen continues the range to 1900 tonnes.
