Improved Dry Vacuum Calibration Tables
Dry vacuum calibration tables were established in response to the need to hold complex plastic profiles to very restricted tolerances while they were being cooled on the extrusion process. Tables were developed to carry the calibration tooling had a need to produce limited tolerances at high output rates and to allow for the simple changeover from one component to another. Even though calibration tooling is needed to attain this, it is extremely expensive and alternate methods have been developed to increase rates without building longer and longer calibration tooling. Tables had to be modified in order to cope with the alternate cooling strategies.
