Drying process

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.

 

Most polymers exhibit at least some level of polarity and can absorb a certain amount of moisture from the air. How much impact that moisture has on the quality of a molded part usually is determined by the resin and the application. Read More

Dryer installation: Going central?

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.

Dryer maintenance: Don’t err with air

Like any piece of machinery on the shop floor, a dryer requires proper maintenance to ensure it is operating efficiently.

Drying

Dryers: Options for a shop’s process

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.

Drying

Resins: Hygroscopic or non-hygroscopic

There are two groups of polymers: hygroscopic and non-hygroscopic. Each has with a set of processing characteristics and an attraction to moisture.
