Injection Molding Machines

Used Sumitomo IntElect 500: Sell or Buy at Auction

Sumitomo (SHI) Demag is a leading manufacturer of all-electric and hybrid injection molding machines: formed from the combination of Sumitomo Heavy Industries and Demag Plastics Machinery. The IntElect all-electric series delivers high precision, energy efficiency, and repeatability for medical, packaging, and technical molding applications. Sumitomo Demag machines are a standard in precision plastics manufacturing.

The Sumitomo (SHI) Demag IntElect 500 is a compact all-electric injection molding machine rated at 500 kN of clamping force, about 50 metric tonnes or roughly 55 US tons. In the IntElect line the model number is the clamping force in kN, so the 500 sits at the small, high-precision end of the range rather than in heavy-tonnage territory. It is built for molders producing small, tight-tolerance parts without the energy draw, hydraulic oil, or maintenance overhead of a conventional press. Direct-drive servo motors run the clamp, injection, and ejector axes independently, which is what gives the IntElect its tight shot-to-shot repeatability and the clean, oil-free operation that clean room, medical, and electronics molding cells depend on. A machine this size typically lands with precision molders running small parts and small multi-cavity tooling: medical device components, electrical and electronic connectors, micro and thin-wall parts, and other technical components where positioning accuracy and low reject rates matter more than raw tonnage. KD Auctions markets machines like this one to its network of 500,000+ industry contacts, and well-documented IntElect units with low cycle counts and complete maintenance records consistently draw strong bidder interest at auction.
