What Precision Coil Spring does

Precision Coil Spring (PCS) is a custom, build-to-print manufacturer of precision springs and formed metal parts, founded in 1951 in Los Angeles and currently operating from a single headquarters and production facility in El Monte, California. The company produces seven core product lines — compression, extension, and torsion springs; wire forms; flat forms; rings; and assemblies — with wire capability from .005" to .626" and exotic alloy handling. PCS serves highly engineered end applications across six vertical markets: commercial aerospace and space, defense, medical, nuclear, energy/gas/mining, and general manufacturing, with named relationships including Boeing, Airbus, and NASA (e.g., Hubble heat transfer components, Space Shuttles, Mars Rover latches, James Webb Telescope).

Manufacturing capability is built around computer-controlled forming equipment, state-of-the-art 4-slide machines for flat forms, in-house heat treating and non-destructive testing, and an 18-unit cycle testing facility. Engineering and prototyping are supported by CAD/CAE tools (CATIA V5, SOLIDWORKS, DraftSight) and a proprietary Advanced Spring Design software used for manufacturability optimization. Quality qualification includes AS9100-D, Nadcap, ISO-9001, ISO-13485, NQA-1, 10CFR50 Appendix B, ITAR, DFARS, CMMC Level 2, and Boeing BAC / Airbus GRAMS approvals.

PCS generates revenue through one-time custom orders, long-term production agreements, and engineering/testing services, all priced on a quote basis. Go-to-market is direct sales from El Monte plus a three-territory independent manufacturer representative network covering Southern California & Mexico, the Eastern United States, and Canada. The company is family-owned through the Goering family, currently in a fourth-generation leadership transition, with 101-250 employees and no disclosed external capital.

Products and services

• Compression Springs Helical springs designed to create resistance to compressive forces, available in straight, cylindrical, conical, hourglass, and barrel forms with wire sizes from 0.005 inch to 0.625 inch for use in valves, pumps, and general consumer goods.
• Extension Springs Springs designed to resist tensile or stretching forces and store energy to exert a pulling force, featuring straight-cut, loop, hooks, and double twisted loop ends with wire diameters from 0.005 inch to 0.625 inch.
• Torsion Springs Helical springs that apply torque or rotary force through angular deflection of spring ends, formed clockwise or counter-clockwise with wire diameters from 0.005 inch to 0.626 inch.
• Wire Forms Custom-shaped wire components that retain components in position and allow for limited deflection, manufactured from round, rectangular, or square wire in sizes from 0.005 inch to 0.626 inch.
• Flat Forms Metal components used to clamp, position, or retain objects, produced on state-of-the-art 4-slide machines with thickness from 0.010 inch to 0.125 inch depending on alloy.
• Assemblies Combination products coupling helical springs or formed spring clips with machined terminals, bushings, cotter pins, washers, and other components for turnkey assembly solutions.
• Rings Springs made from square and rectangular wire used for locating, retaining, clamping, and energizing seals, manufactured with round, square, or rectangular wire in sizes from 0.005 inch to 0.626 inch.
• Engineering Services Custom spring design and engineering services for highly engineered applications using CATIA V5, SOLIDWORKS, DraftSight, and proprietary Advanced Spring Design software.
• Prototyping Services Low-volume part production with specific dimensional and functional requirements, optimizing designs for manufacturability and assembly using Advanced Spring Design software.
• Cycle Testing Services Spring testing and life-cycling services using eighteen in-house spring testers, including long-stroke and short-stroke hydraulic machines, to verify product performance, life expectancy, materials, and manufacturing processes.
• Short Run Manufacturing Services Dedicated short-order department for low-volume production of springs, wire products, stampings, and flat forms with industry-leading delivery and high-quality performance.
• High Volume Manufacturing Services Large-scale production of custom springs and formed metal parts from thousands to millions of units, with quality assurance testing from raw material through final inspection and capabilities including heat treating, non-destructive testing, painting, and part-marking.
