What method is recommended for packaging small parts?
A. There is a point where the sizes of parts reach a point where it is not realistic to consider packaging them individually or in rows. For example connecting rods are generally considered too small to package individually but large enough to package in rows. Bushings are too small to package in rows and are often wrapped 10 or 15 at a time in a cylindrical form. Items smaller than bushings, e.g. fasteners, fittings, etc., tend to be piled into CAPRUST bags for shipment. In this application there is concern as to whether or not the geometry of the massed items will permit all surfaces to be available to the VCI molecules. Also the items will be in contact with each other. Metal surfaces in direct contact with metal surfaces under pressure can suffer a form of attack called crevasse corrosion. Of course the contact points between the items may shift in the package’s transit and this problem may not arise. It has been Wellpack’s experience that a field trial rather than a laboratory tes
