Like any piece of machinery on the shop floor, a dryer requires proper maintenance to ensure it is operating efficiently.
Understanding the properties of a resin and the impact moisture can have on the finished part are important. Drying resin is key to the injection molding process to improve part quality, and there are several types of dryers that are prevalent on shop floors today.
Installing a resin dryer will often be determined by the processing being performed, either on the machine or centrally located in the facility. Often, a mezzanine is used as a central location, freeing up valuable floor space.
There are two groups of polymers: hygroscopic and non-hygroscopic. Each has with a set of processing characteristics and an attraction to moisture.
Drying of plastic resin can be a key step in the injection molding process, since too much moisture can cause a number of processing problems.
