Sumitomo (SHI) Demag, which announced in September it would phase out production of hydraulic presses in Europe, displayed eight all-electric molding machines at K 2025, highlighted by a new 2K IntElect 350t multicomponent press.
The press includes a top-entry SAM-C20 robot and a secondary injection unit situated at a 45-degree angle above the main unit.
By shifting focus to all-electric machines worldwide, Sumitomo (SHI) Demag is moving to more specialized solutions for processors. It will continue to build a smaller number of hydraulic machines in China.
The IntElect 350t includes such special features as a large tie-bar distance for maximum turning diameters, perfectly aligned injection axis drives for higher precision and low energy consumption. These designs provide short cycle times.
The company’s fully automatic activeMeltControl (aMC) system is standard. It compensates for shot-weight variations. Shot-weight variations in 100 percent recycled material can be corrected by aMC to run at the same level as virgin resin.
The new press also includes activeAdjust, Sumitomo’s unique process optimization system that allows the operator to select the best machine control characteristics with slide controls. This means the molding machine can be easily adjusted for a specific product to achieve the shortest possible cycle time.
The NC5+ control system has adjustable clamping force stages, automatic production documentation, automatic mold height and clamping force adjustments, and an automatic injection system for faster shutdown and startup.
Sumitomo (SHI) Demag said sandwich molding, foaming and fiber-glass multicomponent molding are possible with the press.
The IntElect Multi can be supplied with an integrated turntable.
The included SAM-C20 robot is built by Sumitomo (SHI) Demag and is integrated into the molding machine’s control system.
Other molding machines shown by Sumitomo included:
- A high-speed, all-electric Pac-E 420 designed for molding ultra-thin-walled medical applications. Cycle time is 2.6 seconds molding PP parts.
- Another Pac-E 420 that molded HDPE caps in a 72-cavity mold with a cycle time of less than 2 seconds.
- An all-electric IntElect multi-parallel press with SAM C-20 robot. The press is engineered in parallel for maximum stability.
- Bulk Molding Compound technology on an IntElect2 featuring parallel dosing and feeding, energy savings and low shear and fiber damage.
