Custom Metal Fabrication & CNC Machining in Long Beach, CA

A finished metal part is only as good as its last process step. Long Beach OEMs sourcing custom metal fabrication, sheet metal fabrication, and CNC machining often focus on cutting, forming, and machining, and treat finishing as an afterthought, which can undo an otherwise well-built part. Pen Manufacturing fabricates, machines, welds, and finishes parts under one roof at its Anaheim location for OEMs, engineers, and procurement teams across Long Beach and the wider Southern California region, backed by AS9100D, ISO 9001, NADCAP, and ITAR compliance.

Pen Manufacturing’s Anaheim location runs Hurco VMX50 and VMX42 CNC vertical mills, manual lathes up to 15 x 120 inches, and four knee mills for CNC machining. Welding covers MIG, TIG, and structural work to AWS D1.1, D1.2, and D1.6 standards. A Long Beach OEM can combine machined precision components with a larger fabricated or welded assembly, then have it finished, all in one build.

Sheet metal fabrication cuts, punches, bends, and welds flat metal stock into enclosures, brackets, panels, and structural components, using processes including laser cutting, waterjet cutting, stamping, hydroforming, and press brake bending on brakes rated up to 14 feet and 200 tons. All of it runs out of the same Anaheim location as Pen Manufacturing’s machining and fabrication work.

Bare metal is vulnerable to oxidation, rust, and chemical degradation, and skipping or under-specifying a finish is one of the most common and costly mistakes OEMs make when working with a new supplier for the first time. Pen Manufacturing manages several plating and coating processes for its customers, each suited to different applications:
