Every electrically-powered machine is filled with wires, connectors and delicate electronics, such as circuit boards and sensors. These parts are subjected to stress from constant vibration, physical strain, abrasion and impacts. These stresses can damage parts and leave them useless without some level of protection. Parts are also exposed to humidity, moisture and environmental contaminants that can compromise their effective operation.
To protect components from damage, many manufacturers are turning to low-pressure molding (LPM), also known as hot-melt molding, a process that combines the speed and simplicity of injection molding with the strength and durability of casting. It is used to seal assemblies, relieve stress and strain during use, and completely pot and encapsulate sensitive electrical or fiber optic components.
