Twin-Barrel Extruders

Aligning extruders can take hours and hours and it is hard to find methods that actually work, especially for twin-barrel extruders that have multiple sections that need alignment where “stack up” errors can lead to big misalignments. Not aligning extruders causes the barrels and screws to wear out much sooner than desired, leading to excessive costs for replacements. There is a much better way.

L-700 Self-Centering Extruder Borescope Alignment System

Our 50 years of alignment experience went into the design of the L-700 Self-Centering Extruder Borescope Alignment System that makes checking the alignment of extruder barrel sections to gearboxes much easier and much faster:

  • System accuracy of .001 in. (0.025 mm) in 20 feet (6.1 m).
  • The A-510 2-Axis Bore target uses self-centering bore adapters that find the bore center without any moving parts.  It takes just 5- 10 seconds to get a measurement.
  • Uses customized bore adapters with a large range of barrel IDs from 1.18 to 18 in. (30 to 458 mm).
  • The system comes with the A-705 Self-Centering Chuck fixture to mount the L-705 in the center of the gearbox counter bore for ultra-fast setup.
  • Aligns extruders up to 70% faster than conventional or optical borescope methods.
  • Real-time alignment data speeds alignment by showing barrel movements as it’s being  adjusted.
  • Simple, handheld readout show the alignment data in the vertical and horizontal axes.
  • Horizontal and vertical angular adjustment micrometers allow for easy alignment of the laser to the gearbox spindle’s rotation axis.
  • Battery-operated laser with a range of 100 ft. (30 m).
  • Setup in less than 25 minutes.  Data in 5 minutes after that!
