DM III Two-Platen
The Backbone of Your Production Line.
The SM-TP-DM III extends Chen Hsong’s DM III multi-material platform to two-platen scale, from 750 to 1900 tonnes across six models. The turntable is powered by an ABB servo motor with a mechanical pin locking mechanism, achieving positioning accuracy of up to 0.005° and eliminating the misalignment and flash that ruin multi-material part aesthetics. A tunable turntable support system, high-durability bronze wear plates, and a rotary table load capacity of up to 16 tonnes carry heavy multi-material molds with zero sag. The two-platen clamping design provides tie-bar spacing up to 1680×1550mm, opening strokes up to 2650mm, and mold thickness up to 1700mm for large, deep multi-material molds.
Modular main and auxiliary injection units from 960 to 5250 combine in horizontal, lateral, and vertical (H/L/V) arrangements to suit the mold and gating, with three or more materials available via optional three- and four-station turntables. A dual-rod split injection design isolates injection forces from platen rotation, preventing seal wear and oil leaks. Changeover between multi-colour and single-colour production is built in through nozzle centralisation and single-colour ejection holes, so one machine covers both jobs. Every model runs a full servo system with a Linux-based 15-inch touchscreen Intelligent Control Unit. Built for automotive headlight and tail-light assemblies, interior trim, appliance panels, fitness equipment, tool boxes, and other large parts where two or more materials meet.

FAQ
01What Is The Difference Between The DMZ III Two-Platen and The DM III Toggle?
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.
02Why Choose A Two-Platen Design For Multi-Material Molding?
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.
03What Applications Is The DMZ III Two-Platen Best Suited For?
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.
04What Kind Of After-Sales Support Can We Expect?
Chen Hsong provides installation, training, maintenance, and technical support through more than 120 service points, with a professional after-sales team of over 200 specialists, serving customers in 85+ countries.

FAQ
01 How Does the MK7S Compare to the MK6 PRO?
The MK6 PRO is positioned for maximum injection precision and performance (31% higher CPK, ±0.15% injection accuracy). The MK7S is positioned for smart, energy-efficient all-round production with e-Drive™ as standard on every model.
If your priority is the tightest tolerances on demanding parts, the MK6 PRO is the choice. If you want built-in energy savings, faster recovery, and intelligent control across a wider tonnage range (88–1,850T), the MK7S is the platform.
02 What Is e-Drive™ and Why Does It Matter?
e-Drive™ is Chen Hsong’s electric plasticising system. Instead of using the hydraulic motor for screw recovery, an electric servo motor handles plasticising independently.
This reduces plasticising energy consumption by 10-25%, increases recovery speed by up to 30%, a 10-60% increase in melting speed, and a 10-22% reduction in drying time. and enables simultaneous plasticising during mold open/close when paired with valve gates or a shut-off nozzle. On the MK7S, e-Drive™ is standard, not optional.
03What Is the Difference Between MK7S Small/Medium and Large Tonnage Machines?
All MK7S models share the same core platform: e-Drive™ electric plasticising, 15” smart controller, bimetallic screw and barrel, aerogel insulation, and patented circular platens.
Larger MK7S machines (1000T and above) include additional standard features designed for large-machine operation: electric front safety door, clamping area safety footboard, feeding platform, and safety relay. These additions support safe, ergonomic operation on machines handling larger molds and parts.

FAQ
01What Industries Is the MK6 PRO Best Suited For?
The MK6 PRO is proven across automotive, consumer electronics, cosmetics packaging, home appliances, medical consumables, aerospace and defense, and optical components.
The closed-loop precision control and wide material compatibility make it effective for everything from thin-wall LED lighting parts to thick-wall engineering plastic components, particularly where tight tolerances and high CPK matter most.
02What Does ±0.15% Injection Accuracy Mean in Practice?
Closed-loop control measures the actual injection process in real time and corrects deviations during the shot, not after. ±0.15% accuracy means the injected volume varies by less than 0.15% from the set value, shot after shot.
Combined with ±0.25% mold positioning accuracy, this produces a 31% higher CPK than comparable machines, meaning fewer parts fall outside spec and fewer rejects across long runs. Particularly valuable for parts where dimensional consistency or weight tolerance directly affects yield.
03Does the MK6 PRO Support Smart Family Connectivity?
Yes. The MK6 PRO integrates with the iChen™ Smart Family, including iChen Smart Factory, iChen Cloud, and iChen AI Molder, for real-time production monitoring, process optimization, and factory-wide data integration.

FAQ
01What Is The SPARK MS?
The SPARK MS is Chen Hsong’s flagship servo hybrid injection molding machine: electric servo drive on injection, plasticising, and clamping, with a compact built-in hydraulic system for core-pulling and complex molds.
It is the widest-ranging machine in the SPARK family, combining electric precision with hybrid flexibility across a broad span of part sizes.
02What Tonnage Range And Sizes Does The SPARK MS Offer?
The SPARK MS covers 90 to 1700 tonnes of clamping force across 15 clamping sizes, from MS90 up to MS1700. Each size can be paired with a wide choice of injection units and screw configurations, so a single platform can handle precision small parts at the low end and large structural components at the high end.
This makes the MS the broadest range in the SPARK family and a flexible fit for manufacturers running a varied product mix.
03How Precise And Fast Is The SPARK MS?
The SPARK MS achieves ±0.01mm repeatable positioning accuracy, because servo motors directly drive the injection and mold open/close actuators and the process runs under closed-loop control.
On speed, it comes with a standard 160mm/s injection rate for high-speed filling, and electric synchronous plasticising with synchronous ejection runs actions in parallel to shorten the overall cycle. The result is tight shot-to-shot consistency at high output.
04How Much Energy Can The SPARK MS Save?
The SPARK MS pairs a servo motor system with high-efficiency technology to save 30% to 50% energy compared with traditional hydraulic machines, depending on working conditions.
Because the main axes are electrically driven and only a compact built-in hydraulic system handles core-pulling, the machine draws power on demand rather than running a full hydraulic power unit continuously. For high-output production, that saving converts directly into lower operating cost on every cycle.
05What Is AI Molder, And Can The SPARK MS Run Recycled Material?
The SPARK MS suits a wide range of production thanks to its 90–1700T span, electric precision, and hybrid capability: 3C and consumer electronics, automotive components and optical parts, home appliances, medical and hygiene products, connectors, daily-use goods, and high-end toy components.
Its high speed, ±0.01mm repeatability, energy efficiency, and built-in hydraulic core-pulling make it well suited to manufacturers stepping up from hydraulic machines who want electric quality and lower running costs without limiting themselves to a narrow tonnage range.
06What Industries Is The SPARK MS Best Suited For?
AI Molder is the SPARK MS’s built-in smart molding assistant. It automatically tunes molding parameters and self-corrects the process, so the machine can hold high yield rates even when running recycled material.
It continuously optimizes parameters to lift the CPK process capability index, making production more stable and controllable and reducing reliance on experienced operators. Combined with EtherCAT ultra-fast control, a 15″ touchscreen, and OPC-UA connectivity, the MS is built to “think” alongside your team rather than depend on manual trial-and-error.
07How Does The SPARK MS Compare To The Other SPARK Machines?
The SPARK family shares one platform and splits by how much of the machine is electric. The SPARK AE is 100% electric on every axis with zero hydraulic oil, for maximum cleanliness and precision (20–650T). The SPARK EH uses electric clamping and electric injection with hydraulic ejection, injection shift, and core-pulling (100–650T), for applications that need stronger hydraulic secondary functions.
The SPARK HB uses electric injection with hydraulic clamping (130–670T), the most accessible path to electric injection quality. The SPARK MS is the flagship hybrid: servo-electric on injection, plasticising, and clamping with built-in hydraulic core-pulling, AI Molder standard, ±0.01mm repeatability, 160mm/s, and the widest range at 90–1700T.
Choose the AE for zero-oil all-electric work, the MS for the smartest and widest-range hybrid, the EH when hydraulic secondary axes matter most, and the HB for hydraulic clamping at a lower investment.
