Device and method for determining the friction between plastic hollow bodies with the same material composition

摘要

The device (1) has linearly movable hollow plastic structure (2B) that is rigidly clamped on hollow plastic structure (2S). The rigidly clamped hollow plastic structure lies on further hollow plastic structure which is not arranged parallel to the longitudinal axis of rigidly clamped hollow plastic structure. The movable hollow plastic structure is pressed to the rigidly clamped hollow plastic structure with the force (FG). A neck region (3) of the movable hollow plastic structure is connected with a force measuring unit (6). An independent claim is included for method for determining friction between plastic hollow structures of same material composition.
