Our Finishing Services

Below is an in-depth overview of each finishing service, its applications, industries served, and compatible materials.

Sand Blasting & Shot Blasting

Sand blasting and shot blasting remove scale, rust, and surface contaminants to achieve a clean, uniform finish.

These methods also prepare surfaces for further coating, plating, or painting.

Applications: Pre treatment before coating or plating, surface cleaning for cast and forged components, edge smoothing and stress relief, removing oxidation, burrs, and weld residues, etc.

Industries Served: Automotive, heavy machinery, oil & gas, marine, and general manufacturing, etc.

Materials We Process:Steel, stainless steel, aluminum, cast iron, brass, bronze, and nickel alloys, etc.

Zinc Plating

Zinc plating provides a cost effective corrosion resistant coating ideal for components exposed to moisture or moderate atmospheric conditions.

Applications: Fasteners, bolts, nuts, brackets, light-duty automotive and industrial hardware, electrical housings and connectors, etc.

Industries Served: Automotive and EV, electrical and electronics, construction, and consumer goods, etc.

Materials We Process: Carbon steel, alloy steel, stainless steel (select grades), and iron castings, etc.

Chrome Plating

Chrome plating offers excellent hardness, wear resistance, and a highly polished appearance. Suitable for functional and decorative applications.

Applications: Hydraulic rods and cylinders, automotive interior and exterior trim, tools, shafts, and moving mechanical parts, etc.

Industries Served: Automotive, aerospace, industrial manufacturing, and consumer goods, etc.

Materials We Process: Steel, stainless steel, brass, copper alloys, and aluminum (with preparatory layers), etc.

Galvanization

Hot dip galvanizing creates a thick zinc layer ideal for long term protection against corrosion in harsh outdoor environments.

Applications: Structural components, outdoor fixtures and supports, pipe fittings, brackets, frames, etc.

Industries Served: Construction, energy & power transmission, agriculture equipment, and water & wastewater systems, etc.

Materials We Process: Carbon steel, structural steel, and iron castings, etc.

Anodizing (Type II, Type III, Clear, Primer Application, Final Painting)

Anodizing enhances corrosion resistance, surface hardness, and aesthetic appeal of aluminum components. Type III (hard coat) offers maximum wear performance.

Applications: Aerospace and automotive lightweight components, electronic housings, consumer product enclosures, precision machined parts, etc.

Industries Served: Aerospace, automotive & EV, electronics, medical devices, and defense, etc.

Materials We Process: Aluminum alloys including 6061, 6082, 7075, 356, A380, and other casting or machining grades, etc.

Passivation

Passivation removes surface contaminants and enhances the natural corrosion resistance of stainless steel by restoring its protective oxide layer.

Applications: Food grade and pharmaceutical components, precision machined stainless steel parts, medical instruments, and chemical processing equipment, etc.

Industries Served: Medical and healthcare, food and beverage, pharmaceutical, and petrochemical, etc.

Materials We Process: All stainless steels including 304, 316, 410, 420, and 17-4PH, etc.

Impregnation (Porosity Sealing)

Impregnation seals porosity in cast or sintered metal components, preventing fluid leakage and enhancing pressure retention.

Applications: Aluminum and zinc castings, hydraulic parts, valves, pumps, compressor components, high-pressure housings, etc.

Industries Served: Automotive, aerospace, HVAC & refrigeration, and industrial machinery, etc.

Materials We Process: Aluminum castings, zinc castings, magnesium castings, and powder-metal components, etc.

Iso-Static HIP (Hot Isostatic Pressing)

HIP eliminates internal porosity, increases density, and enhances mechanical properties of castings and high performance alloys.

Applications: Critical aerospace and defense components, high-pressure castings, turbine blades, structural parts, medical implants, etc.

Industries Served: Aerospace, defense, medical, and energy (gas turbines, power generation), etc.

Materials We Process: Stainless steel, nickel alloys, titanium, aluminum castings, and high-alloy steels, etc.
