Electronic Shimming: Advanced deep drawing

Hydraulico’s patented Electronic ShimmingTM Plate offers extreme blankhold control
and short start-up time in monoblock deep drawing.

Control the metal flow

Electronic ShimmingTM adjusts the flow of metal dynamically during the deep draw and greatly improves products quality.

The Electronic ShimmingTM Plate is a 80 mm thick metal plate with built-in membranes that transfer hydraulic pressure to the metal sheet

Without Electronic ShimmingTM Wrinkles and scratches in finished product

With Electronic ShimmingTM Flawless product quality with perfect blankhold control

Throw away the shims!

Hydraulico’s patented Electronic Shimming PlateTM offers extreme blankhold control and short start-up time in monoblock deep drawing. With deep drawing, material flow changes significantly during drawing, often causing problems with wrinkles and cracks.

Electronic ShimmingTM reduces scrap rates, facilitates production control, and allows for quick and uncomplicated tool changing.

The system

The Electronic ShimmingTM system developed by Hydraulico has three components:

  • The Electronic Shimming Unit which is a complete electronic and hydraulic system,
  • a control panel and
  • The Electronic Shimming Plate.

The shimming plate holds individual pockets or zones, each pressurized by hydraulic oil and each controlled individually. The control panel allows users to set up pressure zones on the plate, modify pressure during a part of the press cycle and save the settings for future recall.

Fits into any hydraulic press

The Electronic ShimmingTM System can be fitted into any hydraulic press. If desired, Hydraulico can build the plate directly into a new die – a very cost-efficient solution.

We offer a range of shimming plates – single bowl, double bowl, 1 1/2 bowl and 2 1/2 bowl models, but many other types are possible.

 

The facts

Higher product quality, reduced costs:

  • Eliminate wrinkles and cracks by electronic control of material flow
  • Deeper draw possible compared to conventional system
  • Less tension in final product and smaller grain size
  • Higher production output
  • Avoid annealing
  • No start-up time
  • Easy and fast tool changing
  • Reduced polishing cost
  • Payback time: Typically 3-9 months
