POWERPAK All-Electric injection molding machines
High Speed Clamp |
|
Rack and Pinion Clamp Drive |
|
- Sizes from 440 to 1125 tons
- Rack-and-pinion clamp for high-speed, quiet operation
- Ultra precision, reliable and repeatable to 0.001”
- Advanced digital motor-drive-control interface
- Lower inertia & increased response from AC servo motors.
- Hydraulic-free operation - No hydraulic system failures. Cleaner operation.
- Durable, balanced fully mechanical power train.
- Precise Clamp Control: 6-step profiling of clamp close and mold protect ensures optimum operation of the clamp and accommodates multiple plate molds.
- MOLDGUARD™ Most sensitive full-stroke mold protection
Ejection Perfection
- High performance, durable Rollerscrew ejector design
- No ball screws, ball screw timing or breakage
- Rotate the nut, not a screw, for improved cleanliness
- High-speed options
- Eject-on-the-fly is standard
- Easier accessibility to knock out rods
- Fewer components, more reliable
- EJECT GUARD™ Protects machine and mold eject mechanism from high-force eject conditions. Greatly reduces ejector pin/mold damage .
