Types of Clamping


1.   No clamping needed
    a.   Use stock pushers (spring loaded), magnets, T-Pins to retain.
       i.   This may not limit part deformation from weld draw
    b.   Advantages:   Cost, simplicity, tooling lead time, low
          maintenance.
    c.   Disadvantages:   Reliability, repeatability, low clamping force

2.   Manual Clamping
    a.   Common brands include De-Sta-Co, Carr Lane, Wolverine, and
          Irwin.
    b.   Advantages:   Cost, simplicity, component availability,   low
          maintenance.
    c.   Disadvantages:   Operator fatigue, Repeatability.

3.   Pneumatic Clamping
    a.   Common brands include Bimba, Fabco, Parker, De-Sta-Co, PHD.
    b.   Advantages:   Faster cycle time, repeatability, reduced operator
          fatigue.
    c.   Disadvantages:   Overall cost (component and tooling), safety
          requirements.

4.   Hydraulic Clamping
    a.   Common brands include SPX-Hytec, Vektek, Enerpac, Carr Lane.
    b.   Advantages:   High clamping force, faster cycle time,
          repeatability, part “forming”.
    c.   Disadvantages:   Overall cost, pump requirements and interfacing,
          tooling weight.
