Compare and Contrast

 

"Straight or Standard" Press

Slide-Forming Machine

Strengths

  • Simple parts are economical
  • Available in a large variety of sizes and tonnages so "deep draws" are possible
  • Fast production rates: 60-240 parts/min
  • adjusting for material variations is a quick, simple process
  • More options for controlling burr direction
  • process seldom requires a carrier strip, therefore makes more economical use of material
  • Complexities such as
    • Bends > 90°
    • Bends in opposite directions
    • feed accuracy
    • tapping
    are relatively cheap because complexity built into the machine is not duplicated in the job tooling and so is not charged to the customer
  • Tooling costs are comparable to press work for simple jobs, lower for complex jobs

Weaknesses

  • Larger presses have lower production rates
  • adjusting for material variations is a slow and complex process
  • Little design control over burr direction
  • most parts require a "carrier strip", extra material that is scrapped at the end of the process
  • Complexities such as
    • Bends > 90°
    • Bends in opposite directions
    • feed accuracy
    • tapping
    are relatively expensive because the complexity must be built into the job tooling for every job
  • generally smaller presses and lower tonnage than straight presses
  • therefore slide machines can not do extensive deep draw or stretch form operations
