The SPARK EH combines electric servo clamping and injection with hydraulic ejection, injection shift, and core-pulling in a single integrated machine. Electric plasticising improves plasticising efficiency by 30% with up to 30% energy saving. Four patented technologies, including Auto Stress Release (ASRS) and ALL-Adapt, protect part quality and handle everything from 0.25mm ultra-thin wall to 20mm ultra-thick wall.
Hydraulic ejection, injection shift, and core-pulling are built in, so there is no need for a separate hydraulic power unit alongside your machine. Patented circular platens, closed-loop injection pressure control, and a 15″ EtherCAT touchscreen controller with OPC-UA connectivity round out the platform. For manufacturers who want electric clamping precision with full hydraulic capability ready to go. 100 to 650 tonnes across 10 clamping sizes.
The SPARK EH is a hybrid injection molding machine that combines electric servo clamping and electric servo injection with hydraulic ejection, injection shift, and core-pulling, all in one integrated machine.
It delivers electric clamp-and-injection precision while keeping full hydraulic capability on the secondary axes, with no separate hydraulic power unit required, across a 100–650T range.
Agile Boost Control (ABC) optimizes motion profiles for each axis.
Auto Stress Release System (ASRS) monitors screw movement in under 1ms and uses a patented counter-pressure mechanism to release internal stress, improving part quality.
ALL-Adapt (AA) enables a single machine to handle everything from 0.25mm ultra-thin wall to 20mm ultra-thick wall.
AxP with Floating Point Toggle dynamically adjusts the ball screw for collision protection while reducing noise and shortening cycle times.
The EH uses electric drives on the two axes where precision matters most (clamping and injection), then adds hydraulic power on the secondary axes where force is useful.
Hydraulic ejection gives increased force on demanding molds, hydraulic injection shift gives stronger nozzle contact force, and standard hydraulic core-pulling is included. Because all of this is integrated, there is no need for a separate hydraulic power unit beside the machine, so you get electric precision and hydraulic muscle in a single footprint.
The SPARK EH covers 100 to 650 tonnes of clamping force across 10 clamping sizes, from EH100 up to EH650.
Each size can be paired with a choice of injection units and screws, and ALL-Adapt technology lets a single machine span 0.25mm ultra-thin wall to 20mm ultra-thick wall.
The SPARK EH is designed for precision applications that also require hydraulic capability: automotive connectors, consumer electronics housings, medical components requiring core-pulls, and any production where you need electric clamping and injection precision alongside hydraulic ejection, core-pulling, or stronger nozzle contact force.
The SPARK family shares one platform and splits by how much of the machine is electric.
The SPARK EH uses electric clamping and electric injection with hydraulic ejection, injection shift, and core-pulling (100–650T), for applications that need electric clamp precision plus stronger hydraulic secondary functions. The SPARK AE is 100% electric on every axis with zero hydraulic oil (20–650T), for maximum cleanliness and precision.
The SPARK MS is the flagship hybrid: servo-electric on injection, plasticising, and clamping with built-in hydraulic core-pulling, AI Molder standard, and the widest range at 90–1700T. The SPARK HB uses electric injection with hydraulic clamping (130–670T), the most accessible path to electric injection quality.
Choose the EH when hydraulic secondary axes matter most; the AE for zero-oil all-electric work; the MS for the smartest, widest-range hybrid; the HB for hydraulic clamping at a lower investment.
