Feed Shoe Material
Feed Shoe Material
(OP)
I work in a company that produces a product that is used by the the military. The process is very much like powdered metal pressing. Instead of metal powder we are pressing very reactive mixtures of powders to make a solid material. The problem is that our feed shoes are experencing extreme amounts of wear. We have tried several types of plastics (UHMV, Poly). One other problem is foreign objects, shoe material and organic material in our pressed item causes very noticable effects on performance, so in Xray inspection we have a reject products with FO.
My next shoe material is going to be anodize aluminum. Any other sugestions to a shoe bottom that i should try?I am also looking to get input on changing out our current automatic feed shoe design.

Other factors to consider is that all the pressing and manufacturing takes place in a dry room kept at 50 degees F and less than 0.3% relative humidity. We are replacing the shoe material once every 3-4 days which is about 2600 cycles of the shoe going through its motion. How does this compare to other feed shoe maintanence/replacement in the powdered metal industries?

It is difficult (often wrong) to offer solutions without understanding the cause of the problem. I would recommend a systematic failure analysis before selecting a suitable material or material-coating system.
