Plastic Injection Molding and Types of Plastic

Plastic injection molding is a process that allows a business to create parts in any number.  The key thing to note is that there are several types of plastics around. 

Types of Plastics Used in Plastic Injection Molding

Plastic is an essential component of numerous products from product containers and water bottles all the way up to construction materials.   All plastics aren't the same, however.   

The Society of the Plastics Industry is an advisory board that sets standards for plastics and plastic injection molding.  According to their site:

"SPI introduced the Resin Identification Code (RIC) system in 1988 at the urging of recyclers around the country. A growing number of communities were implementing recycling programs in an effort to decrease the volume of waste subject to rising tipping fees at landfills. In some cases, these programs were driven by state-level recycling mandates.

The code was developed to meet recyclers' needs while providing manufacturers a consistent, uniform system that could apply nationwide. Because municipal recycling programs traditionally have targeted packaging - primarily containers - the coding system offered a means of identifying the resin content of bottles and containers commonly found in the residential waste stream. The RICs are used solely to identify the plastic resin used in a manufactured article.

In 2008, SPI began work with ASTM International, a globally recognized leader in the development and delivery of international voluntary consensus standards, to develop a new standard that would expand the current RIC system. In 2010 ASTM International issued ASTM D7611 - Standard Practice for Coding Plastic Manufactured Articles for Resin Identification.  In 2013 ASTM International announced revisions to ASTM D7611 including a change to the graphic marking symbol used to identify resin type. The RIC system has used a “chasing arrows” symbol surrounding a numeral from 1 to 7 that defines the resin used in the product’s packaging. Under D7611, this marking symbol is now specified as a solid equilateral triangle around the number. By replacing the chasing arrows graphic – commonly associated with recycling – with an equilateral triangle, ASTM D7611 stressed the focus to the system’s core mission: resin identification and quality control prior to recycling. Other modifications to the RIC are currently being discussed and developed by ASTM's D20.95 subcommittee on recycled plastics.  [READ SOURCE]
