Overview
The Fanuc Roboshot Alpha-S100iA is Fanuc's all-electric injection molding machine, featuring precision servo-driven control on all axes. While technically an injection molding machine rather than a VMC, it represents Fanuc's precision manufacturing philosophy applied to plastics processing with the same CNC-grade accuracy standards.
The S100iA has a clamping force of 1,000 kN (100 metric tons) with a maximum shot size dependent on the screw diameter selected (22-36 mm options). Platen dimensions are 560 x 560 mm with tie bar spacing of 410 x 410 mm. Maximum mold thickness is 410 mm.
All-electric drive eliminates hydraulic oil, reducing energy consumption by up to 70 percent vs hydraulic machines. Servo-driven clamp, injection, ejection, and metering provide repeatable precision with cycle-to-cycle consistency measured in hundredths of a gram.
The machine runs on Fanuc's 31i-B control with the Roboshot-specific HMI, providing injection profile control, SPC monitoring, and connectivity to Fanuc's iFactory IoT platform. Dry cycle time is approximately 1.5 seconds.
Machine weight is approximately 4,500 kg. The S100iA integrates seamlessly with Fanuc robots for part removal and insert loading. Fanuc's global service network provides support in every major manufacturing region.
New machines price $120,000-$180,000. Used 2016-2022 trade $60,000-$110,000.

Frequently Asked Questions
01
New $120,000-$180,000. Used $60,000-$110,000.
02
No hydraulic oil means cleaner operation, up to 70% energy savings, faster dry cycles, and better shot-weight repeatability.
03
1,000 kN (100 metric tons). Suitable for small to medium plastic parts.
04
Seamless with Fanuc robots via the 31i-B control. Fanuc builds both the machine and the robot.
05
Technically an injection molding machine, but it uses the same Fanuc servo technology and 31i control platform as Fanuc machining products.
