Optical Sorting

The Anochrome Group can offer additional services such as optical sorting and crack detection at its Wolverhampton facility.

Defect Free

The use of this equipment enables work to be virtually defect free as far as dimensions are concerned, such that an extremely low number of defects in a few parts per million can be obtained.

Contamination Free

A far less discriminatory method of automatic screening can be used that will remove contaminants from a batch by using a significant characteristic.

Optical Sorting Machine

With the increasing use of automatic assembly systems, it is essential to  have good quality fasteners. The Optical Sorting Machine makes this possible by rejecting defective parts. The machine will also separate the accidental mixtures of work inevitable in any high volume plant production.

The machine can check:

  • Shank length
  • Shank diameter
  • Presence of a good thread
  • 2-start threads
  • Head diameter
  • Head height
  • Recess infill
  • Crack detect/ open bursts

Machine features:

  • High speed
  • Quick setting – easy changeover
  • Parts counted
  • Batching facility
  • Anti-jam mechanism
  • Close tolerances

Counting Facilities

6 figure counters are provided to indicate the total number of parts checked and the number of good parts selected. In addition to these counters, there is a 5 figure batch counter which stops the machine when a pre-set number of good parts has been counted.
