    How to make a sheet metal match

First let me explain the application: We make fireplaces, about 150,000 per year, each one uses four refractory panels and during the mixing of these panels we install a wire mesh as a binder for each panel. These wire mesh components cost about .70 each and the math comes to about $420,000.00 per year in wire mesh. I did some testing and found if I install a few hundred strips of metal about the size of a paper match into the mix for each panel, the binding is equal to the mesh. I have plenty of scrap metal from 22 to 30 gauge and my only problem is to find a paper shredder on steroids, since I need about 2 million metal matches per day. I have talked to many companies that build machines and nobody has the answer. If anyone could solve this problem there is a round of golf at pebble beach in your future.

    Try to contact motor lamination fgabricators. Off-all (scrap)from stator or rotor lamination stampings have various size pieces that fall out of the slots for magnet wire windings. They will not be same shape as a paper match, but the variety of sizes may serve the function. Typically this off-all is transfered by conveyor systems into a scrap trailer and sold as recycle steel. Depending upon the stamping house you may find there is all you need.

    You might contact Sweed Machinery in Gold Hill Oregon. They make different types of machines for cutting metal strapping and wire into bulk (short) sizes. You could start with round or flat stock. They might be able to help.

    Some other possibilities:

    Turn stacked metal panels on a lathe and use the shavings for filler.
    -or-
    Since you manufacture refractory, melt your scrap metal and mold your own webbing (providing the energy costs prove feasible).
    -or-
    Punch holes in the scrap metal and use as is.

    P.S. If the lathe turnings idea works, you may be able to get the leftover turnings from various machine shops for free or at a favorable cost, or even trade them for your scrap metal.
