We are a world class spring manufacturer with unique capabilities in exotic alloys and highly engineered formed products.

Precision Coil Spring, located in El Monte, California, has been manufacturing custom designed springs since 1951. We retain over 2,500 combinations of alloys/sizes/forms of raw materials for fast response times. This, coupled with our decades of experience with exotic alloys and enhanced by our diverse manufacturing capabilities, translates into exceptional springs built to customer specifications. PCS manufactures build-to-print spring products for key markets, such as: Aerospace and Aircraft, Nuclear, Medical, Military/Ordnance, Computers and Electronics, Commercial, Defense, and Rail Transportation. We have a dominant position in titanium springs for the Aerospace market and a leading position for springs used in nuclear reactors. Although we use all the common steel and copper alloys, we specialize in more exotic alloys; in particular, titanium, Inconel, Elgiloy, Hastelloy, 17-7PH, and other stainless steels. In addition to compression, extension and torsion springs, we manufacture wire forms and flat forms on 4-Slide equipment, and we make value-added assemblies and various ring designs.  Our products are manufactured to precise customer specifications under Statistical Process Control and Statistical Quality Control and also conform to Aerospace, Military, NASA, or Nuclear Industry standards and practices as specified. We are AS9100-C, ISO 9001:2008 and NADCAP certified, and we comply in full with Mil-I-45208 for complete traceability. We work with our customers to fulfill procurement requirements, whether to develop a long-term agreement, a min/max program, stock consignment, or other needs. Using our years of engineering experience, combined with state-of-the-art spring design software, we are ready to assist in developing your specific design configurations.
