Over-molding is a manufacturing process that combines two different types of plastic together to create a single part. Typically, this involves the use of a hard plastic and a softer plastic (often rubberized). Alternatively, this method can be used to bind two hard plastics together that are different colors. Overall, this is a process that takes various materials with different properties and combines them into a single molded component.
Last week we discussed the parts we manufacture for Garmin Aerospace – in-mold decorated (IMD) overlay assemblies and over-molded adjustment knob assemblies. We produce various types of both parts, which can be found in the cockpit of smaller aircrafts. In this post we will discuss the process and benefits of both types of parts.
