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 so far as dimensions are concerned, an extremely low number of defects, just  a few parts per million can be realised.

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
  • Presence of cracks/ open bursts

Machine features:

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

Counting Facilities

Six 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 five figure batch counter which stops the machine when a pre-set number of good parts has been counted.
