FRICTION is a common force that significantly affects the motion of moving objects in a system. Reducing Friction with respect to Food Automation Equipment is a challenge that engineers are constantly faced with. So how do you determine what is the optimum sliding material for your application? To answer this we first define the two types of friction, Static and Dynamic.

Plastic materials are used throughout the processing and conveyance of food. Materials that have direct contact with food are required to meet the strict requirements of the US Food and Drug Administration (FDA) and/or Regulation 10/2011 EU. In addition to compliance, the materials pose a potential issue in terms of foreign body contamination. This refers to pieces of the plastics that can break off and contaminate the food stuff during usage creating a potentially costly situation for the food end user. Plastic particles are of the most prevalent foreign body contaminants due to the fact that plastic is not inherently able to be identified by the typical metal detection or X-Ray detection systems. For that reason, plastic shape manufacturers have developed technologies to increase the detectability of plastics in food processing environments.
