Helical Products Company

What Helical Products Company does

Helical Products Company, founded in 1958 and headquartered in Santa Maria, California, manufactures precision flexible components — specifically machined springs, beam-style flexible shaft couplings, and U-joints — under the registered HELI-CAL brand. The company's core technology is a proprietary process of machining solid bar stock to produce spring-like flexures with precise spring rates in compression/extension, torsion, and bending configurations, including multi-coil designs and integrated end attachments in a single piece. This single-piece construction is positioned as an alternative to traditional wire-wound springs, enabling customization across coil count, spacing, ID/OD measurements, and torque characteristics. The 51-100 employee operation runs an AS9100 and ISO 9001 certified production facility with on-site testing for extended cycle life.

The company operates a dual-channel commercial model. For custom OEM engagements, Helical Products sells direct to enterprise engineering teams in aerospace, defense, automotive, medical, semiconductor, and energy, supported by in-house engineering, prototype development, quote-based pricing, and multi-year contract cadence. For standard catalog products (beam couplings, helical couplings, U-joints), the company leverages a distributor network for fast delivery, supplemented by a self-service online Coupling Selector tool and educational seminars. Aerospace and semiconductor are identified as primary verticals. Helical Products operates as a subsidiary and brand within MW Industries (MW Components), a diversified precision components group headquartered in Charlotte, North Carolina. The company is privately held with no disclosed revenue, funding events, leadership changes, or M&A activity in the input data.

Core offering

Helical Products Company designs and manufactures precision machined springs, flexible shaft couplings, and U-joints using its proprietary HELI-CAL machining process, which produces single-piece spring-like flexures from solid bar stock. The company offers both standard catalog products for fast delivery and custom-engineered solutions designed to OEM specifications, serving aerospace, semiconductor, automotive, defense, energy, and medical industries from an AS9100 and ISO 9001 certified facility in Santa Maria, California.

Product overview

Helical Products Company, founded in the 1950s and operating under the HELI-CAL® brand, offers a portfolio of precision-engineered flexible components manufactured through a proprietary machining process. The core product line consists of three main offerings: HELI-CAL Machined Springs (custom springs machined from solid bar stock with single-piece construction), HELI-CAL Beam Couplings (flexible shaft couplings invented in 1958 using beam-style flexure technology), and HELI-CAL U-Joints (torque transmission components capable of operating at angles up to 90 degrees). All products leverage the company's proprietary HELI-CAL flexure technology and are produced at an AS9100 and ISO 9001 certified facility. The company serves aerospace, automotive, defense, energy, medical, and semiconductor industries with both standard catalog products and custom OEM solutions.
