We have the following finishes available – please select a finish for more information:

Anodize

Definition:
Sulfuric acid anodizing is a conversion on aluminum which changes the surface to an aluminum oxide. It has greater abrasion resistance, corrosion protection and is non conductive. The aluminum oxide builds up on the surface and penetrates into the material an equal amount. Sulfuric acid anodize can be dyed various colors.Specs:

Black Nickel

Definition:
Electroless black nickel-phosphorus plating is an advanced electroless nickel plating process formulated to deposit a black finish. It is a decorative functional RoHS compliant metal finish. The black nickel will mask the surface condition of the substrate. Dull parts will plate matte black nickel. Polished parts will have high gloss black nickel appearance. Heat treating the black nickel will increase corrosion resistance, harden the black layer and stabilize the deposit color. Black nickel is a conductive finish which can be used as a replacement for anodize when the non conductive finish is inappropriate for the function. The black nickel finish is used with a low phosphorus electroless nickel, but a base layer of medium or high phosphorus electroless nickel can be used to increase corrosion resistance. Black nickel popularity is growing in the defense, aerospace, ammunition, mechanical and electronic industries.

Bright dip

Definition:
Bright dip is an immersion acid based application used to protect and clean copper and brass. The finish can remove scale, oxide and tarnished surfaces leaving a uniform natural color. The material will readily oxide and JMD recommends using a conversion coating to further protect the material from corroding.

Copper

Definition:
Copper plating is electrolytically deposited metal finish that has functional and decorative characteristics. Decorative finishes are often lacquered after plate due to the fact copper readily oxides. Functionally copper is used because of its excellent electrical and thermal conductivity. Copper is also used as a base layer or underplating. The benefits of underplating are improves final finish, improves adhesion and improves corrosion resistance.Mil-C-14550Class 0- 0.001-0.005″ minimum deposit, heat treatment stop-off shield

Electroless Nickel

Definition:
Electroless Nickel alloys of nickel and phosphorus with a auto catalytic chemical reduction of hypohpphite forms a unique coating which does not require an external current. This process produces coatings of uniform thickness which is beneficial when plating irregularly shaped objects, holes, recesses, internal surfaces, valves or threaded holes. Electroless nickel is more corrosion resistant then traditional electrolytic nickel.JMD offers low, medium and high phosphorus content electroless nickel:

Electropolish

Definition:
Electropolish is a process that removes material from the surface of stainless steel which creates a smooth, bright, mirror-like finish. The finish resembles polished chrome plating. Electropolish can also be used for deburring, cleaning, and passivating.

Etching

Definition:
Caustic etching is a immersion process that is used for cleaning and removing oxides which provides a consistent, uniform matte finish. The finish is commonly used for deburring, and preparing parts for paint, powder, anodizing, chromating and other metal finishes.Acid etching is a mild form of cleaning aluminum. The acid etching process JMD follow does not remove material which makes it a great candidate for machined parts with tight tolerance holes. This finish will not dull the material but will remove oxidation from the surface of aluminum.

Hardcoat Anodize

Definition:
Hardcoat anodizing forms a non-conductive aluminum oxide on the surface of the aluminum substrate. It increases corrosion resistance, wear resistance and is a great adhesion base for primers/paints/glues. The properties of this finish help retain lubricants and PTFE coatings. Hardcoat anodize is the second hardest naturally occurring substance; second only to diamonds.Specs:

Screen Printing and Part Stamping

Definition:
Screen printing is a technique that uses a woven mesh to support an ink-blocking stencil. This is most commonly screen on parts that have already been processed through a number of metal finishes. This allows for a very graphic and visual end product. Screen printing is more versatile than traditional printing methods, such as etching or lithography, as it does not have to be printed under pressure. A variety of different inks can be used to screen print almost any material or object.JMD Industries screen printing capabilities include:
• Part stamping
• Screen burning
