Pallet Design System

Information from the NWPCA

The Pallet Design System© is based on engineering fundamentals and matrix structural analysis techniques. It is the result of many years of laboratory research and field-testing. NWPCA and the William H. Sardo, Jr. Pallet & Container Research Lab have invested an enormous amount of time and resources to create and enhance this outstanding design and marketing tool.

PDS© simulates pallet strength, stiffness and life cycle analysis based on user-specified descriptions of the material-handling environment. This system can be used to estimate the performance level of a particular pallet design or assist in creating a new design to meet a precise performance level. PDS© has been in use since 1984 and is currently used by pallet manufacturers and recyclers in 15 countries.

PDS© can assist in the design of many kinds of pallets:

Two through Five Stringer
2-way or partial 4-way; 4,6 and 9-block
Post-style pallets of any size
Single or double-face
From commonly used wood species-hardwoods, softwoods and mixtures
Single- or double-winged
Single or double cantilever
Flush reversible or non-reversible
Structural wood composite panels
With a full range of parts dimensions
Those made with commonly used fasteners – nails and staples
Rack and stacked storage
Handled with forklifts, floor jacks and slings
To support fully or partially distributed loads; flexible or rigid case goods, bagged goods or block-type loads
Single or multiple concentrated loads – barrels, drums, steel coils

What PDS© can do for your customers:

· Enhance pallet performance.

· Enhance product protection.

· Improve safety for workers throughout the supply chain.

· Reduce material handling costs.

· Help them recognize your company as a unit load consultant and partner.

“When you use PDS©, you have over 20 years of research and development supporting your pallet.”  Marshall White, Ph.D., Director William H. Sardo, Jr. Pallet & Container Testing Laboratory

Version 3.35

NWPCA is pleased to announce extraordinary innovations to what is already recognized as the wood packaging industry’s leading marketing and design tool. PDS© has a new version, 3.35, with features that will expand your ability to serve your customers and attract new ones:

· Custom load types – users can select different custom load types such as boxes, bulk boxes, bags, bulk bags, pails and blocks for better wood pallet designs and more accurate performance predictions.

· Box stacking pattern – single layer, column stacked and interlocked stacked boxes can be selected for better design and more accurate analyses.

· Load stabilizer – the effects of stretch or shrink wrap and horizontal and vertical banding on load flexibility have been incorporated. Vertical banding can either be perpendicular or parallel to pallet length.

· Load-bridging response – long-term creep tests were incorporated in this version to quantify load-bridging response over time.

· Copyright statement – new copyright language has been added to PDS© output to provide more legal protection to all leaseholders.

· Watermark – a translucent mark with company name and license number can now be printed onto all PDS© output.

· A simplified grading specification for pallet components – the new grading system will replace the current 18 grades in PDS©. The objective is to have only one set of pallet component grade that is independent of species and geographical region.
