The SPARK HB pairs electric servo injection and plasticising with hydraulic clamping, ejection, injection shift, and core-pulling. 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.
The most accessible entry point to electric injection precision in the SPARK range, covering up to 670 tonnes. Hydraulic clamping keeps costs down and delivers the force your production floor depends on. Patented circular platens, closed-loop injection pressure control, and a 15″ EtherCAT touchscreen controller with OPC-UA connectivity complete the platform. A practical upgrade path from pure hydraulic machines for manufacturers who need better injection quality without the full investment of all-electric.
The SPARK HB is a hybrid injection molding machine that pairs electric servo injection and plasticising with hydraulic clamping, ejection, injection shift, and core-pulling.
It is the most accessible path to electric injection quality in the SPARK range: you get the precision and energy savings of electric injection while keeping the familiar, lower-cost hydraulic clamping system, across a 130–670T 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.
Yes. The SPARK HB retains hydraulic clamping, which means your existing toolroom and maintenance teams keep working with a familiar clamping system.
The upgrade is on the injection side, where electric servo drives deliver significantly better precision, repeatability, and energy efficiency than hydraulic injection. You get measurably better part quality without retraining your production floor on an entirely new machine architecture.
The SPARK HB covers 130 to 670 tonnes of clamping force, pairing electric servo injection with hydraulic clamping.
Each size can be matched 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 HB suits a wide range of production: automotive components, home appliances, consumer electronics, medical devices, and general precision molding.
It is particularly well suited for manufacturers currently running hydraulic toggle machines who want to improve injection quality, reduce energy consumption, and increase shot-to-shot consistency without a full-electric investment.
The SPARK family shares one platform and splits by how much of the machine is electric.
The SPARK HB uses electric injection with hydraulic clamping (130–670T), the most accessible path to electric injection quality and a practical upgrade from pure hydraulic machines.
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 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.
Choose the HB for hydraulic clamping at a lower investment; the AE for zero-oil all-electric work; the MS for the smartest, widest-range hybrid; the EH when hydraulic secondary axes matter most.
