We provide precision metal bending services including CNC press brake forming, multi-stage bending, and custom contouring, capable of processing stainless steel, aluminum, and carbon steel with consistent accuracy and quality verification.
Applications & Advantages
We deliver high-strength structural components for enclosures, frames, brackets, and assemblies across machinery, automotive, and construction sectors, ensuring reliable performance for prototypes and volume production.
How Metal Bending Works?
Metal bending is a precision forming process that shapes sheet metal, plate, or structural profiles into accurate angles and complex geometries through controlled deformation. The service begins with a digital CAD model, which is translated into machine instructions for CNC press brake systems. The material is securely positioned, and specialized tooling applies calculated force along programmed axes to achieve consistent bends with high repeatability across production runs.
This combination of advanced CNC control, expert process engineering, and custom tooling solutions enables the fabrication of high-strength, dimensionally stable components.
At JS Precision, we provide professional metal bending services for enclosures, frames, brackets, and assemblies across aerospace, automotive, machinery, and construction sectors, ensuring tight tolerances and superior surface finishes from prototyping to full-scale production.

Polishing
Produces a smooth, high-gloss surface that improves corrosion resistance and elevates visual appeal for decorative or high-visibility components.
Sand Blasting
Utilizes pressurized media to clean and texture surfaces, resulting in a consistent matte finish ideal for paint or coating adhesion.
Tumbling
A batch finishing process that gently deburrs and smooths edges through abrasive action, providing a uniform surface for small parts.
Anodizing
An electrochemical process that increases corrosion and wear resistance on aluminum, while allowing for durable color dyeing.
Powder Coating
Applies a durable, wear-resistant polymer coating in a wide range of colors and textures, offering excellent environmental protection.
Electroplating
Deposits a thin metallic layer such as nickel or zinc to enhance surface hardness, corrosion resistance, and electrical conductivity.
Black Oxide
A conversion coating for ferrous metals that provides mild corrosion resistance, reduces light reflection, and minimizes part glare.
Alodine Coating
A chromate conversion coating primarily for aluminum, offering excellent corrosion protection and improved paint adhesion.
Heat Treatment
A controlled heating and cooling process that alters the microstructure of metals to increase hardness, strength, or ductility.
Passivation
A chemical treatment for stainless steel that removes free iron from the surface, enhancing corrosion resistance.
