Custom Machining ServicesBuilt Around Your Specs

When precision matters and timelines are tight, Electro-Seal delivers. Our custom machining services are designed for manufacturers, engineers, and OEMs who need dependable, made-to-spec components — whether it’s a one-off prototype or a full production run.
From CNC and screw machining to secondary operations like heat treating and coating, we provide a full spectrum of in-house services to take your design from concept to completion.

One Partner. Infinite Possibilities.

Electro-Seal has spent decades fine-tuning our machining capabilities to support complex parts, tight tolerances, and custom materials. We serve clients across industries including automotive, aerospace, oil and gas, food processing, pharmaceuticals, and industrial equipment manufacturing.
We handle jobs others won’t — or can’t.

CNC Machining

High-precision turning, milling, drilling, and tapping on a wide variety of metals and plastics. Ideal for tight-tolerance and geometrically complex parts.

Screw Machining

Multi- and single-spindle screw machines enable efficient production of small-to-medium-sized components in high volumes or custom configurations.

Prototyping

Rapid prototyping for concept testing, validation, and fit/form/function evaluation before full-scale production.

Small Lot & Short Runs

No need to meet high minimums — we specialize in limited-volume production with consistent quality and fast turnaround.
