Rake Angle Guide for Machining

One of the most important factors in machining is the geometry of the cutting tool, and one component of that is the rake angle. A tool’s rake angle will affect how much material can be removed, how easily chips form and break, the horsepower required to cut, and even the tool’s life. It must be […]

PPSU Injection Molding

Polyphenylsulfone (PPSU) is an injection-molded plastic that resists high temperatures and harsh chemicals. Injection-molded PPSU parts are also tough, dimensionally stable, and impact-resistant. They can withstand steam autoclaving, hot water with detergents, and other demanding conditions. Filled and reinforced grades of this material are also available. Because it’s a specialty plastic, PPSU costs more than […]

SAN Injection Molding

Styrene acrylonitrile (SAN) is a copolymer, or polymer blend, that combines the properties of styrene and acrylonitrile. Styrene contributes to SAN’s transparency, stiffness, and excellent processability. Acrylonitrile imparts SAN’s hardness, rigidity, and resistance to heat and chemicals.  Because of its exceptional properties, injection molded SAN is considered to be a specialty plastic rather than a […]
