Screw-on capping machine

press-onintermittent-motionaerosol

Overview
Mastercap automatic indexing capping machine designed for automatic application of screw caps, press-on caps and tamper-evident closures to bottles and containers. Built for fast, accurate and repeatable capping to improve line throughput. Supports aerosol overcaps and inserts.

Key product features

• High-efficiency capping
  Speeds up to 3300 caps per hour to improve line throughput and ROI.
• Cap diameter range
  Handles caps from 20–80 mm, covering standard consumer, industrial and pharmaceutical formats.
• Construction
  304 stainless steel frame and hygienic parts suitable for industrial and hygienic environments.
• Waste reduction
  “No container, no cap” and queue sensing to minimise cap waste.
• Safety
  Capping zone protected by interlocked guards.
• Variable torque
  Magnetic clutch for adjustable torque to suit cap types and prevent overtightening.
• Low-level cap detection
  Cap track detection to avoid production interruptions.
• Cap feed system options
  Automatic cap elevator, rotary disc feeder or vibratory bowl feeder depending on cap type and orientation requirements.

Cap feeding options (details)

• Automatic cap elevator – for most screw and press-on caps.
• Rotary disc feeder – stabilises and continuously orients caps.
• Vibratory bowl feeder – for small or lightweight caps requiring precise orientation.

Applications
Fully automatic application of screw caps, press-on caps, tamper-evident closures, aerosol overcaps and inserts on bottles and containers; suitable for pharmaceutical, cosmetic, food & beverage, chemical and industrial packaging lines.
