Shrinkage postmold

This indicates the inherent shrinkage of a material during injection molding. Molding conditions, orientation of fillers, orientation of flow, and other factors can influence the specific level of shrinkage, but the inherent quality is material dependent. This is the immediate level of shrinkage. Postmolding CTystallization is accounted for by dimensional stability. [Pg.108]

Alkyds. Alkyd resins consist of a combination of unsaturated polyester resins, a monomer, and fillers. Alkyd compounds generally contain glass fiber filler, but they may also include clay, calcium carbonate, alumina, and other fillers. Alkyds have good heat, chemical, and water resistance, and they have good arc resistance and electrical properties. Alkyds are easy to mold and economical to use. Postmolding shrinkage is small. Then-greatest limitation is extremes of temperature (above 175°C) and humidity. [Pg.363]

Alkyds are easy to mold and economical to use. Molding dimensional tolerances can be held to within 0.001 in/in. Postmolding shrinkage is small. The compounds are molded by compression, transfer, and sometimes injection molding techniques. [Pg.28]
