LAMINATION PLATE
TADCO AISI 4140 Steel Lamination Plate


Long-Lasting Steel Plates
-
TADCO's special heat-treatment process alter steel mechanical properties under controlled condition. Our process not only improve the strength but enables a prolonged period of flatness retention for the plates
Precision Bushings and Recess design in the plates
-
TADCO's bushings undergo broaching process that eliminates potential stress risers in the slot corners, thus considerably reducing the risk of head cracking.
-
broaching allows for a tight Total Indicated Runout (TIR) tolerance, as it minimizes the accumulation of tolerance. TADCO sets a stringent tolerance requirement of 0.0002" TIR for location accuracy, which is essential for ensuring optimal registration accuracy of plates.
-
Recessing bushings on the plates can extend life of bushings by removing excess pressure on the head
CMM report on each plate upon request
-
TADCO has made a significant investment in a high-quality Coordinate Measuring Machine (CMM) and has placed it in a temperature-controlled environment to ensure precise measurement data.
-
Through the integration of TADCO plates and bushings, we intend to achieve unparalleled precision in hole location accuracy on the plate. This approach will serve as a robust foundation for the lamination process, resulting in exceptional registration accuracy.
Re-Work Service
-
Through specialized heat-treatment process in conjunction with a recessed bushings design, it is achievable to restore the used plates to a new state. This comprehensive refurbishment may involve operations such as surface flatness restoration, counterbore reformation, and the replacement of bushings.

TADCO Aluminum Top Spacer Plate


Enhance the registration accuracy
-
TADCO has developed a solution to enhance the registration accuracy of lamination tooling packages. The innovative Top Spacer Plate system comprises aluminum plate that can be conveniently placed over an existing tooling top plate.
-
The plate features relief holes that enable the use of full-length pins without the risk of collision with the platen. This results in superior pin engagement, which significantly improves registration accuracy.
