Horizontal injection molding machine e-cap series

servo-electricfor HDPEtoggle

Product overview
The e-cap is an all-electric toggle‑lever injection molding machine engineered specifically for high-throughput production of plastic closures (caps). Designed for continuous operation under heavy load, the e-cap achieves cycle times < 2 s for typical HDPE caps while maintaining a clean mold area and consistent part quality.

Key application

• High-volume production of plastic closures (e.g. 26 mm HDPE caps) for packaging lines with very short cycle requirements.

Main highlights

• All‑electric toggle‑lever concept delivering high dynamics and repeatability
• Fast clamping unit with encapsulated 5‑point toggle; moving platen designed for cycle times < 2 s under continuous load
• Clamping force up to < 4,200 kN (series dependent)
• Injection unit optimised for HDPE with dedicated screw geometries for reliable melt preparation
• Encapsulated toggle and sealed lubrication to ensure a clean mould area (no oil mist)
• Water‑cooled servo‑electric drives and water‑cooled kinetic energy storage to reduce energy consumption

Control & digitalisation
The CC300 integrated control provides intuitive operation and straightforward integration of robots and peripherals. ENGEL digital options such as e-connect.monitor (condition monitoring) and e-connect.24 (remote maintenance) enable component monitoring and worldwide remote support.

Benefits

• Very short cycle times < 2 s for efficient cap production
• Reduced energy consumption through water‑cooled servo drives and kinetic energy storage (up to approx. 50% vs. hybrid machines)
• Improved part quality from a clean mould area (encapsulated toggle, sealed bearings, closed spindle lubrication, linear guides)
• Designed for continuous, heavy‑duty packaging operation with permanent monitoring of lubrication and motor temperature
• Suitable for integrated production cells (machine, robot, peripherals) with digital process transparency
