Hat pad
VARIOPRINT-Patent Nr. 10 2008 015 641

VARIOPRINT hat pad systems allow the precise coating of drill holes with a depth/diameter ratio of approx. 1:1.

Application example:

A drill hole with a diameter of 15 mm is coated with lubricant to a depth of 13 mm.
Printing block moves over the hat pad. The coating medium is provided in the required layer thickness.

In an inflated condition, the hat pad moves onto the printing block and takes the coating medium
Hat pad moves into the drill hole to be coated and passes the coating medium on to the drilling wall through expansion
