Glossary of Terms
* Dry Time – Time required to dry resin. This is specific to each grade/type of plastic resin. Some resins do not require drying
* Flexural Modulus – PSI rating where resin breaks from bending
* IMM – Injection Molding Machine
* ISO – International Organization for Standardization
* IZOD – Impact Strength Test following ASTM standards
* Melt – resin viscosity in g/10min at a specific temperature
* PPAP – Production Part Approval Process
* Resin/Material – Plastic Pellets used in molding
* Rockwell Hardness – ASTM D785 test to determine durometer of finished part
* Shrink Rate – All molded plastic parts shrink as they cool coming out of a mold. The shrink rate is the amount of shrink each grade/type of plastic shrinks measured in inches
* Tensile Strength – PSI rating where resin pulls apart
* Tonnage – The potential mold clamping force available in a Injection Molding Machine, measured in tons. This commonly states the size of the machine
* UL – Underwriters Laboratory: International Organization certifying electrical components for use in residential and commercial applications
