Aluminum Tube Crusher This is an instrument to evaluate the amount of force required to crush a Aluminum Tube in the Vertical or Horizontal Direction. This is also suitable to perform a 'Liner Cracking Test' on coated / lined tubes. Significance : A high Crush Value is directly proportional to the rigidity of the Tube. Excessive rigidity leads to consumer rejections. Poor rigidity leads to flimsy / cracked tubes. Tubes that have a coating / lining inside them can also be crushed on this machine and later checked for 'liner cracking'. This 'Liner Cracking Test' is very essential for the cosmetic / pharmaceutical industry as certain chemicals present in the paste can react with the tube material if the internal liner gets cracked. This equipment is relevant to : Manufacturers of Aluminum Tubes. Cosmetic / Pharmaceutical manufacturers who are heavy consumers of Al. tubes. Research Institutions. Packaging Development centers.
