Packing for WD-Series Coils
Below are instructions for packaging a WD-Series Coil for safe shipping. While Western Instruments goes
to greater lengths to package these Coils for shipment, we understand the constraints on some companies
when it comes to preparing heavy shipments. To ensure no ‘in transit’ damage, Western typically provides
a ‘crate’ that protects the Coil with plywood on all sides.
1. Cut 2 identical pieces of plywood that are greater than 9mm (3/8” thick). The pieces are to be about
25mm (1”) longer than the Coil is high, and again 25mm (1”) greater than the width of the Coil. 2 pieces
of wood, approximately 40mm x 40mm (1.5” x 1.5”) need to be cut, for making this package ‘palletized’.

2. Using wood screws, approximately 38mm (1½”) long, attach the pieces of wood to 1 of the pieces of
plywood, as illustrated below. These screws are started against the plywood and driven through, into
the wood below. Each piece of wood should be about 50mm (2”) from each end of the plywood. We
use at least 5 screws to secure each piece of wood.

3. Cut 2 of the pieces of foam, the same size as the plywood, and wrap the Coil in Plastic. The plastic
can be a bag, large enough to hold the coil, or stretch wrap, which is Western’s preferred material.
Failure to cover the coil in plastic, may cause the Coil housing to stick to the foam.

5. Place the second piece of foam against the top of the Coil, and cover it with the second piece of
plywood. This has ‘sandwiched’ the Coil between both pieces of foam and plywood.

6. Pressing firmly (15kg or 30 pounds) against one end of the sandwiched assembly, use either Stretch
wrap or packing tape to firmly hold the sandwiched assembly tight together.
7. Pressing firmly (25kg or 50 pounds) on the opposite end of the sandwiched assembly, again use
either
stretch wrap or packing tape to wedge the sandwiched assembly firmly together. Again, we prefer
stretch wrap, because the first secured end will be allowed to stretch slightly, making the sandwich
much tighter.

8. The sandwiched assembly can now be placed up-right, so further stretch wrap can be used to fully
secure the middle portion of the sandwiched assembly together. Care should be taken to ensure the
2
stretch wrap or packing tape does not cover the two pieces of wood forming the pallet.

9. The sandwiched assembly can then be placed in the flat position, like it will be handled. Again use
stretch wrap or packing tape to fully secure the 4 exposed edges of the coil, as illustrated below.

Note: If you have used Stretch Wrap, like we recommend, to fasten the sandwiched assembly
together, then finish all exposed edges with packing tape to reinforce the stretch wrap. Be
generous with the packing tape, as even many layers of stretch wrap is not as resilient as
packing tape.
10. The packaging can now be identified as Fragile and to use arrow stickers to indicate which way the
shipment is to be handled. Address labels should be placed on all sides and the top of the package.
Further, Western Instruments should be contacted so the correct shipping (export) documents can be
attached to the shipment.
Note: We have specified Plywood as it complies with international norms for shipment (ISPM 15).
Any other ‘Wood’ used should be ‘treated’ with methyl bromide to ensure it is compliant as well.
