Delrin, also known as Polyoxymethylene (POM), is a precision engineering plastic renowned for its stiffness, low friction coefficient, and outstanding dimensional stability. At Hason Industries, Delrin is machined into gears, valve components, sliding plates, mechanical linkages, spacers, timing pulleys, bushings, washers, electrical coil housings, and calibration fixtures. It is particularly valued in pharmaceutical machinery for its smooth surface finish, repeatable accuracy, and resistance to deformation under load. Delrin maintains dimensional accuracy even in service conditions involving high mechanical pressure and rapid movement cycles, making it indispensable for precision motion control systems.
Our stock of Delrin sheets and rods ranges from 6 mm to 100 mm in thickness and from Ø15 mm to Ø200 mm in diameter. With high-precision 3-axis CNC mills, routers, and lathe systems, Hason Industries can machine Delrin components up to 2,200 mm × 1,200 mm in size. Delrin’s minimal thermal expansion allows us to hold tight tolerances on features such as gear tooth profiles, shaft fits, and guide slots. We also offer custom surface finishing, chamfering, threading, taper machining, and press-fit tolerance optimisation.
In electrical insulation applications, Delrin provides excellent dielectric strength and minimal moisture absorption, enabling parts like switchgear sleeves, terminal spacers, and sensor housings to operate safely. For pharmaceutical-grade handling systems, Delrin’s hygienic properties and resistance to repeated sterilisation cycles allow it to be used confidently in contact surfaces, handling trays, and dosing equipment. Its ability to slide smoothly without lubrication prevents contamination risks.
At Hason Industries, our team combines industrial experience with advanced CAD/CAM programming to optimise tooling strategies, reduce wear marks, and maintain high part consistency in batch production. All Delrin components undergo dimensional verification, visual inspection, and structural integrity checks before dispatch. With our stringent quality control and machining expertise, Delrin remains a top-tier choice for operational precision.
