Ultrasonic Horizontal Sprue Cutter
Working Principle
The equipment consists of an ultrasonic generator, transducer, sonotrode (horn), horizontal frame and intelligent control system. The generator converts mains AC into high-frequency electrical signals above 20kHz, which are transformed into mechanical vibrations of the same frequency via the piezoelectric effect of the transducer. Amplified by the sonotrode, the vibrations are precisely applied to the junction between the sprue and the part. Tens of thousands of high-frequency vibrations per second cause intense molecular friction, instant heat and stress concentration at the sprue, resulting in clean separation within 0.5–1 second with no burrs or marks, and no damage to the product body.
Application Fields
Ideal for various hard thermoplastics and some alloy parts requiring sprue/runner removal after injection molding, especially for:
- Electronics: ABS, PC, PS, PA, PMMA precision components
- Home appliances: Small structural and decorative parts
- Automotive: Lamp housings, interior trim, small functional parts
- Daily plastics: Cosmetic packaging, caps, transparent parts
- Precision hardware: Zinc alloy and aluminum alloy small die-cast sprue removal
Key Advantages
✅ Horizontal Design, Automation-Friendly
Horizontal layout with low-pressure operation, easy integration with injection molding robots for unmanned production lines; compact footprint and flexible installation.
✅ Perfect Finish, High Yield
Ultrasonic “cold cutting” delivers burr-free, non-whitened, crack-free and mark-free surfaces; no secondary polishing needed, directly enhancing product quality.
✅ Intelligent & Digital, Stable & Easy to Use
Full-color touchscreen + digital generator with automatic frequency tracking, overload protection and 10%–100% adjustable amplitude; parameter storage and fault alarms enable easy operation even for new users.
✅ Wide Material Compatibility, Multi-Purpose
Compatible with hard plastics such as ABS/PC/PS/PA/PMMA and zinc/aluminum alloy small parts; one machine for multiple production lines.
