• LAUFFER Pressen - Introducing two ways of deep drawing (Jul 12, 2023)

  Today, we want to take a closer look to two deep drawing methods.
  Let's explore:
   
  Variant A: Deep drawing with draw cushion
  In deep drawing with draw cushion a flat sheet of metal is placed in a mold and pressed into the mold by a punch.
  The draw cushion, which is located between the stamp and the sheet, creates a counterpressure to pull the sheet into the mold and produce complex three-dimensional parts.
  The part is produced with the opening facing downwards. (Hat position)
   
  Variant B: Deep drawing with a double-acting ram.
  In deep drawing with a double-acting ram without a draw cushion, the flat sheet is placed between a movable ram and a fixed die.
  The (outer) ram presses the sheet firmly onto the outer edge of the die, and the inner ram presses the sheet into the die.
  The part is produced with the opening facing upwards. (Tub position)
   
  Comparison:
  Discover the reasons of the differences behind the Variant A over Variant B in deep drawing: automation.
  By flipping the deep drawing process, Variant A positions the flat surface on top (Hat position), allowing for easier handling and ensuring smooth product transfer.
   
  Energy-efficient and deeper drawing of parts are advantages of the Variant B compared to Variant A.
  At Lauffer Presses we have many years of experience in both variants for your individual ideas.

  Currently we have a triple-acting press RZV 340 in the making using the classic deep drawing variant (B).

  The machine will be located in Oklahoma and ready for production in November 2023.

• How you can use servo-hydraulic presses to ensure your competitiveness in times of energy transition. (Jul 27, 2023)

  A guide with practical advice and further recommendations.

  Productivity, efficiency and sustainability, were and are, important criteria for decision-making in investment projects. This is even more true in times of energy transition, high inflation and for investments that have a long-term impact.

  In addition, there are many technical possibilities and combinations for the drive concept of hydraulic presses, which play out their individual advantages depending on the application. For some years now, solutions with servo technology have been increasingly advertised with a wide range of benefits. However, the buyer unfortunately rarely has the time and expertise to look in detail with the available options and is often disoriented by the extensive offers and the associated promises.

  For clarification of the situation and technical explanation of typical drive systems, we have written a guide which can be found under the following link.

  https://lauffer.de/wp-content/uploads/2023/07/Lauffer_Whitepaper-servo-hydraulic-presses_24.07.2023_EN.pdf

  This guide provides you with assistance and advice for choosing the appropriate press system for the industrial production of stamped or formed metal and composite components. The evaluation takes place based on an operating cost analysis that considers both the holistic acquisition costs and the ongoing costs for operation and maintenance. The relevant parameters are in the field of tension and include a large number of technical as well as business aspects.

  Finally, the guide shows useful options that can significantly increase the overall efficiency of the modern hydraulic press with minimal additional investment.

• Inline Process Diagnosis (Jul 27, 2023)

  How you can analyze your forming process with the Lauffer process data analysis and thus optimize it in a targeted manner.

  Forming processes include many physical parameters that influence among other things product quality, machine energy efficiency and tool lifetime. Traditionally, however, these parameters are usually only considered in retrospect and iteratively adjusted for future production batches. As a result, an optimization of the forming process requires a lot of time, so that a relevant improvement is only noticeable after numerous production batches.

  In order to accelerate this process and optimize the parameters in a more targeted manner, LAUFFER has developed an inline process diagnosis. This function allows the operator to examine each stroke on the user interface in detail and also to compare it with all strokes from the past. This means that the parameters can be changed during the ongoing production batch and the influence on the component can be evaluated directly. The findings enable shorter iteration loops and thus faster optimization of the entire production.

  A brief overview of all the functions of LAUFFER Process Diagnosis:

  • Loading and filtering of all recorded strokes
  • Comparison with arbitrary reference strokes
  • Free diagram construction by the user
  • Exporting the recordings in PDF format
  • Cursor for examining momentary values
  • Zooming options for more detailed analysis of areas of interest
