Tips of the Trade: Seven tips to consider when purchasing used machineryTips of the Trade: Seven tips to consider when purchasing used machinery
Most of the equipment it makes is tangential to the primary and auxiliary machinery in plastics processors' facilities, but Larry Stoma, design engineer for the Witte Co., a manufacturer of screeners, classifiers, fluid bed dryers, coolers, conveyors, and de-waterers, has shared some solid tips applicable to purchasing any type of used machinery. The Internet makes it easier to find such equipment, but asking the right questions is still key to making sure you understand exactly what you are getting.

Courtesy of Stoma, here his seven tips to better purchasing of used machinery:
*First, determine what the process needs, then search online based on these needs. If the equipment would not solve the problem, then any price is too high.
*Know exactly what's offered. If there's any doubt about what is pictured or described, then involve an engineer with experience in designing and operating similar equipment.
*Call the manufacturer with the serial number and ask for the original specifications to get a comparison to the equipment being offered for sale.
*Ask for manuals, training guides, maintenance logs and any other information that may be available.
*Verify the dimensions and compare to your facility - including doorways.
*Understand that most warranties are non-transferrable and voided when the equipment is modified in the field.
*Know local regulations. Most secondhand equipment sellers are unlikely to be current on the regulatory environment in fifty different states, or in different countries.
