Since 1947, Quakertown-based INSACO has precision-machined and polished technical ceramics, sapphire, glass, and quartz for demanding applications. Founded as Industrial Sapphire Specialties making phonograph needles, the company later produced sapphire cover plates for the first Telstar satellite and now works from a plant spanning more than 50,000 square feet. INSACO measures and documents parts to tolerances sometimes reaching millionths of an inch, with experience ranging from prototypes to automated production.
