PMMA material for injection mold parts
PMMA or acrylic is thermoplastic with high transparency, high flexibility, and chemical resistant, weather-resistant and light weight. It is preferred over poly-carbonate (PC) because of its properties i.e. easy to process, low cost and flexibility. PMMA material is widely used in rapid manufacturing industries to fabricate fine prototypes. As acrylic is thermoplastic which means it can be liquefied at its melting point and can be restored to its original shape upon cooling. So, this feature of PMMA or acrylic makes it perfect for injection molding.
