A new metal forming process has been introduced to economically produce metal parts that previously could not be formed.

Posted: March 7, 2016

The fluid forming process enables Innovative product design through the use of organic and geometric shapes that may incorporate the use of textured and pre-finished materials, all of which can be cost effectively integrated into each part/product. Trademarks, brands, and logos can all be easily incorporated into each part design.

Dr. Jürgen Pannock of FFA explains how fluid forming is a timely and cost effective development-prototyping process. Functional modeling, simulation, verification of design, tooling and manufacturing can be completed in short order. This means the process of design concept through part manufacturing can also be completed quickly and with little risk, and significantly lower costs when compared to legacy processes and the attendant risks of process incompatibilities.

Dr. Jürgen Pannock of FFA explains the operation of the Form Balancer 25 fluid forming machine to attendees.

Step One. Material is loaded into the die for processing on the Form Balancer 25 fluid forming machine.

Step Two. The cavity is closed and sealed and water injected at 60,000 psi during the fluid forming process on the Form Balancer 25 fluid forming machine.

Step Three. A finished part unloaded off the Form Balancer 25 fluid forming machine at FFA.

The fluid forming process enables the use of thinner materials, tighter radius, more intricate designs and part nesting. Better design and consistent part fit-up increase efficiency and improves transfer performance.

Paul Benny of FFA explains how the fluid forming process significantly reduces initial asset acquistion costs in dies, tooling and fixturing for metal forms. Ongoing need for tooling repair and maintenance is also greatly reduced and total life is extended due to the reduced stress on the formed part and tooling. Total cost of ownership is greatly improved.

A metal forming process that utilizes H2O as the force to form parts at 60,000 psi was introduced to aerospace, automotive and medical parts suppliers and other local contract manufacturers during an open house event hosted by FluidForming Americas, LLC (FFA; Hartsville, TN) on Friday afternoon, March 4.

FluidForming Americas was founded and launched in August 2015 by Paul Benny, the company president; Dr. Jürgen Pannock, the chief technology officer; and Reinholdt Wesselman, the managing director of parent company FluidForming GmbH (Vechta, Germany) and the inventor of the fluid forming (FF) process. FluidForming Americas manufactures parts using fluid forming technology and leases FluidForming machinery in the Americas.

After lunch and opening ceremonies, Dr. Pannock walked through a presentation that explained fluid forming (FF) technology and the diverse application opportunities it opens for the design and formation of metal from .004 in to .1969 in (1.01 mm to 5 mm) thick. Water is forced at pressures up to 60,000 psi to economically create innovative metal part designs that could not be formed previously. The FF process is exceptionally cost effective for short run needs and prototyping of parts requiring less than 500,000 annually.

A tour of the facility followed and attendees got to see their Form Balancer 25 fluid forming machine in action to better understand the process technology and further discuss potential application opportunities. The FF process produces consistent, high quality parts with first pass yield results of 99.996 percent. This essentially eliminates rework and non-conformance of parts to reduce scrap and ensure consistent parts fit-up. Parts cross-contamination is removed as one side of the part comes into contact with only water. Lightweight metals can be used in lieu of castings, forgings, overly complex forms and plastics because the process virtually eliminates material overcompensation for thinning, internal stresses and springback, i.e., no more expensive and environmentally stressful castings.

The FF process has already been proven as ideal for making heat exchangers, bipolar plates, perforated metal sheets, system cases for personal computers, all sorts of kitchen accessories and laboratory equipment, and medical applicances.

Lithuania as EU’s springboard for investment: from Musk’s projects to the automotive and agribusiness industries

Membership in the European Union (EU) has ensured access to a single market for goods and services with around half a billion consumers. Investors are familiar with the older Western democracies, but the countries that have joined the EU relatively recently also have something to offer. Lithuania is particularly active in the geographical centre of Europe, and is competing for investments, both in relation to Elon Musk’s projects and for completely new greenfield projects, for which it is offering preferential tax conditions.
