A hybrid injection molding machine combines electric servo drives on the injection and plasticising functions for the highest shot precision and fastest response, with hydraulic power for cost-effective tonnage and capability. The result sits between pure hydraulic and pure electric: better repeatability and lower energy consumption than hydraulic, at a fraction of the price-per-tonne premium of fully electric. For manufacturers upgrading from older hydraulic machines, hybrid is the practical path to electric-level shot performance without rebuilding the production floor. Hybrid sits alongside Chen Hsong’s full injection molding machine range of hydraulic toggle, two-platen, all-electric, multi-material, vertical, and high-speed packaging machines.
Every Chen Hsong machine is ready for smart manufacturing through the iChen™ platform. iChen™ Smart Factory connects machines, automation, and production systems into a complete MES solution. iChen™ Cloud provides real-time monitoring, quality tracking, and data-driven operations across your entire fleet. iChen™ AI Molder applies AI-driven process intelligence to optimize molding parameters, reduce defects, and stabilize output, without relying on operator experience alone.
As a global injection molding machine supplier with 120+ service locations, Chen Hsong supports manufacturers in automotive, packaging, electronics, medical, home appliance, and industrial production with machines, automation, and smart factory solutions.
Chen Hsong’s SPARK series offers three hybrid configurations, differing in how much of the machine runs on electric servo. SPARK MS, the flagship, runs servo-electric injection, plasticising, and clamping with built-in hydraulic core-pulling, plus AI Molder and ±0.01mm repeatability, making it the smartest and most automated hybrid.
SPARK EH keeps electric clamping and injection while building in hydraulic ejection, shift, and core-pulling, for production needing stronger hydraulic auxiliary functions without a separate power unit.
SPARK HB pairs electric injection and plasticising with hydraulic clamping, the most accessible option and the easiest upgrade from pure hydraulic. All three share the SPARK platform’s precision injection technology, including patented circular platens and the ALL-Adapt™ processing window, and suit automotive, electrical and electronic parts, consumer products, and technical molding with engineering resins.
All three are hybrids and differ by how clamping and the auxiliary axes are driven.
SPARK MS is the flagship: injection, plasticising, and clamping all run on electric servo, with a built-in hydraulic system for core-pulling, plus AI Molder, ±0.01mm repeatability, and 160mm/s standard injection speed. It has the widest range at 90 to 1,700 tonnes.
SPARK EH runs electric clamping and injection with hydraulic ejection, injection shift, and core-pulling built in (100 to 650 tonnes), best when you need stronger hydraulic auxiliary functions.
SPARK HB runs electric injection and plasticising with hydraulic clamping (130 to 670 tonnes), the most accessible path to electric injection quality and the easiest upgrade from a pure hydraulic machine. All three share the same
SPARK precision injection technology, 15-inch touchscreen control, EtherCAT-based motion control, and ALL-Adapt™ wide-range processing window.
All-electric machines use servo motors on every axis. They deliver the highest precision, lowest energy consumption, and oil-free operation. Best for medical, optical, electronics, and cleanroom production (up to around 650T at Chen Hsong).
Hydraulic toggle machines use servo-driven hydraulic systems and offer the widest tonnage range (15 to 1,850T at Chen Hsong) at the best value per tonne.
Best for general-purpose production. Hybrid machines combine electric drives on the precision axes (injection, plasticising) with hydraulic power on clamping and/or auxiliary functions, delivering electric-level shot precision with hydraulic-level tonnage and cost. Best for technical molding and as an upgrade path from pure hydraulic.
Hybrid machines are the right choice when your production needs better shot precision and energy efficiency than a pure hydraulic machine, but the higher price per tonne of a fully electric is hard to justify.
Common reasons to choose hybrid include upgrading from older hydraulic machines without rebuilding your production floor, technical molding with engineering resins (PC, PA, PET) where shot consistency matters, applications above 650 tonnes where all-electric options are limited or expensive, and energy-cost reduction targets. Chen Hsong evaluates your application to recommend the right SPARK variant.
Hybrid machines are the standard choice for production needing electric-level shot precision combined with hydraulic-level tonnage and value.
Typical applications include automotive components, connectors, and optical parts; 3C and consumer electronics housings and panels; home appliance parts; medical devices and hygiene products requiring core-pulling; high-end consumer goods and toy components; and technical molding with engineering resins (PC, PA, PET) where shot-to-shot consistency is critical.
Manufacturers upgrading from older hydraulic machines also choose hybrid as a practical step up to electric injection quality without rebuilding the production floor.
