Precision and flexibility for standard, complex, and customized applications e-mac all-electric medium and small injection molding machine

In an all-electric machine like the e-mac, every process-relevant movement is driven by a servo-electric motor – energy is only consumed when the machine moves. In a hydraulic machine, the pump runs continuously regardless of whether the machine is in motion or waiting. This fundamental difference accounts for energy savings of 30% to 70% with all-electric machines. Beyond energy, the all-electric drive eliminates hydraulic oil from the clamping area entirely – a meaningful advantage for cleanroom, medical, and food applications. Additional differences include quieter operation (below 65 dBA), shorter start-up times, and significantly reduced maintenance consumables.

Not every application requires an all-electric machine. But when your production priorities include tight tolerances, repeatable shot quality, reduced operating costs, or a clean manufacturing environment – the all-electric drive makes a measurable difference. Key indicators that all-electric is the right choice:

• Your application requires consistent part weight and dimensional accuracy

• You produce in or near a cleanroom environment

• Energy costs per part is a competitive factor

• Quieter operation matters on your shopfloor

• You want to reduce consumables – no oil, no filters to change

The all-electric drive alone reduces energy consumption by 30% to 70% compared to hydraulic machines, since energy is only drawn during machine movement. Add ENGEL's iQ flow control and e-flomo temperature control, and additional energy savings of up to 45% are achievable on top of that baseline.

The e-mac is ENGEL's all-electric small injection molding machine for standard applications. It covers clamping forces from 500 to 5,000 kN across 13 machine sizes and is used across medical, packaging, electronics, sustainability, and contract manufacturing applications – from straightforward, high-volume production runs to more demanding applications requiring precision, clean manufacturing environments, or specialized materials.

The e-mac is a strong fit when you need an all-electric medium to small injection molding machine with high precision, energy efficiency, flexible configuration options and a compact footprint. If your application requires higher clamping force, specialized machine layouts or different performance requirements, ENGEL North America can help compare the e-mac with other ENGEL machine models and recommend the best fit.

The e-mac series covers 500 to 5,000 kN clamping force across 13 machine sizes – from the e-mac 50 for small, precise technical parts to the e-mac 500 for high-volume packaging applications. Every size runs on a fully electric drive with the same encapsulated toggle design.

The e-mac is available with three electric injection unit configurations; each matched to a specific production profile:

• Standard – Cost-efficient production of standard injection molded parts

• High – High injection speeds up to 800 mm/sec for reliable production of thin-walled technical parts

• Heavy Duty – Sustained high holding pressure for thick-walled components

Yes – the e-mac's flexible machine concept and extensive option portfolio make it a capable platform for multi-component injection molding applications. Its precise, all-electric drive system and consistent process stability make it well-suited for multi-shot parts that demand accuracy and repeatability. Contact our team to discuss the right configuration for your specific application.

The e-mac HIGH is the right choice when output per shift is the primary production target. Its high-performance clamping drive enables shorter cycle times for high-volume production. Combined with iQ motion control, it optimizes mold movement for faster cycles and a faster return on investment.

The e-mac slim is up to 16% narrower than the standard version of the same model – with tie-bar spacing and mold installation area kept identical, so production capability is never traded for a smaller footprint. It is the right choice when production floor space is genuinely constrained – for example, in cleanroom cells or space-constrained manufacturing environments where each additional machine on the floor has a direct impact on capacity and cost.

Yes. The optional e-mac cleanroom package makes the machine suitable for applications up to ISO 7. The encapsulated toggle lever reduces lubricant consumption by up to 90% and eliminates oil leakage – making it a cost-efficient solution for medical and pharmaceutical production without the need for a dedicated cleanroom machine.

The encapsulated toggle lever uses up to 90% less lubricant than conventional designs and produces no oil leakage at the clamping unit. This, combined with the optional cleanroom package, brings the e-mac into compliance with ISO 7 requirements – without the cost of a purpose-built cleanroom machine.

Yes. The e-mac's precise process control and stable injection unit make it well suited for demanding materials, including post-consumer recycled (PCR) plastics and bio-based alternatives. The e-mac 220 has been used in production with 100% PCR material using foam injection molding, achieving 30% material savings compared to conventional production.

In most cases, no significant compromise is required. The e-mac's precise, repeatable process control and stable injection unit help maintain consistent shot weight and part quality even with the added variability common in recycled materials. Digital assistance systems such as iQ weight control can further stabilize the process by automatically compensating for material-related fluctuations, helping you process sustainable materials without sacrificing output.

Yes. The e-mac can be combined with ENGEL viper linear robots, easix six-axis robots and other automation solutions. Machine and automation can be operated through the integrated CC300 control interface, helping simplify setup, operation and production monitoring. Stock e-mac machines can also be configured with robot integration (EUROMAP 67) before delivery when automation is part of your production plan.

Yes. The e-mac's CC300 control unit integrates with ENGEL's e-connect.24, giving you remote access to machine data, diagnostics, and production monitoring from anywhere. Digital assistance systems like iQ flow control and iQ weight control can also be added to further stabilize the process — turning your e-mac into a connected, data-driven part of your production line.

ENGEL maintains standard, non-customized e-mac small injection molding machines in stock across a wide range of sizes in the U.S. for manufacturers that need faster availability. If your application can be supported by an available stock machine, ENGEL can help you get into production faster. Stock machines can also be individually configured with selected options before delivery, including robot integration.

If your application requires a more customized solution, ENGEL North America can build a quote around your specific part, mold, material, production goals, automation needs and budget. Our team can help determine whether a stock machine or customized configuration is the better fit.
