About Used All-Electric Injection Molding Machines

All-electric plastic injection molding machines (also called electronic injection moulding machines) use servo motors instead of hydraulic pumps for all machine movements β€” clamp, injection, ejection, and plasticization. This eliminates hydraulic oil, reduces energy consumption by 30-50%, and provides exceptional repeatability and precision. Electric injection molding machines are the preferred choice for cleanroom medical molding, precision electronics, and applications requiring tight tolerances.

Key advantages of all-electric molding machines include faster dry cycle times, lower energy costs, reduced noise levels, no hydraulic oil contamination risk, and superior shot-to-shot consistency. These machines excel at producing medical components, optical parts, electronic connectors, and thin-wall packaging where precision is critical.

Meadoworks stocks used all-electric injection molding machines from Fanuc (Roboshot), Sumitomo Demag (SE-EV/IntElect), Toshiba/Shibaura (EC series), JSW (J-AD), Milacron (Roboshot), Nissei (NEX), Engel (e-motion), and Arburg (Allrounder A). All-electric machines typically command a 20-40% premium over hydraulic equivalents in the used market due to strong demand and superior performance characteristics.

Frequently Asked Questions

What are the advantages of all-electric injection molding machines?

All-electric machines offer 30-50% energy savings, superior precision and repeatability, faster dry cycle times, lower noise, no hydraulic oil (ideal for cleanrooms), reduced maintenance costs, and lower operating temperatures. They're the preferred choice for medical, electronics, and precision molding applications.

How much do used all-electric injection molding machines cost?

Used all-electric plastic injection molding machines typically cost 20-40% more than comparable hydraulic models. Small all-electric machines (50-150 tons): $30,000-$100,000. Medium (150-500 tons): $60,000-$250,000. Large all-electric machines (500+ tons): $150,000-$500,000+. Fanuc Roboshot, Sumitomo, and Nissei all-electric machines are among the most sought-after in the used market.

Are all-electric injection molding machines better than hydraulic?

It depends on the application. All-electric machines are superior for precision, energy efficiency, cleanliness, and speed. However, hydraulic machines still dominate in very large tonnages (1500+ tons), offer lower purchase prices, and are well-suited for general-purpose molding where ultimate precision isn't required. Hybrid machines combine benefits of both.
