Specimen Notching Machine for Plastic Impact Bars

Precision broaching machine that cuts V-notches of defined radius and depth in molded plastic bars before impact testing. Used in injection molding QC and polymer test labs.

Specification

Consistent notch geometry decides the reliability of any Izod or Charpy result. This machine uses a rotary cutter with a sharp profile and a clamp that holds the specimen square. Depth is set with a graduated screw and verified with a gauge.

Features

• Single or three-tooth broaching cutter
• Depth setting with micrometer screw
• Quick-action specimen clamp
• Notch angle 45 deg and radius 0.25 mm
• Chip tray for easy cleaning
