All the information you need. In one place.

Acid

A corrosive, water-soluble substance. The metal industry employs it as an echant to chemically corrode metal that is unprotected and has been exposed to light, as part of the manufacturing process of precision metal parts and etching technology.

Bend Lines

Lines are half etched into a metal template to assist with bending. Bend lines are used to form complex components and parts, shielding boxes, jewelry, and tools.

Bevel

A “v”-shaped slope. The slope is formed in the groove that joins the two sides of metal after having undergone a two-sided etching process.

Composite Materials

A composite material is an intentionally engineered structure produced by combining constituent materials of different physical and chemical properties, to produce a better and more durable material. Its unique quality lies in that the individual materials remain separate and distinct, while offering more durability at high temperatures, and having lower density.

Dies

Metal stencils manufactured with CNC technologies, intended for a range of  cutting applications and suitable for all types of materials. Common uses: dies for producing blades and cutting tools, template production, and labels.

Electroless Plating

Coating metal parts without electricity. The catalytic plating is formed by an aqueous solution containing complex metal ions and stabilizers. Plating improves the durability of the metal and makes it corrosion resistant.

Electrolytic Plating

Coating metal using electricity. The plating is formed by conducting an electric current through a solution (electrolysis). The coating improves the durability of the metal and makes it corrosion resistant. Plated parts become solderable and extend the range of use.

Etching Line

The outline of the part that is formed.

Laser Welding

 A precision method to fuse metal parts by creating a bond using molten metal. Various metals can be welded together, and welding can be carried out with bonding material (electrodes), or without (depending on the alloys that are being welded).

Milling

 A computer controlled process to shape components made of metal or other substances through the removal of excess material using a variety of tools – lathes, saws, grinders, drills, and CNC milling machinery.

Photo Electroforming

A process that forms metal on a conductive base (a mandrel). The metal conductor is cleansed and selectively coated in a light-sensitive material. It is exposed to UV radiation, put into an electrolytic solution, and suspended in a bath for a certain length of time to form various metal parts. The duration of suspension affects the height of the parts that are produced. When the process is finished, the mandrel is removed.

Photo Etching

Also known as photo chemical machining, (PCM), photo chemical milling or photo chemical etching, is the selective chemical corrosion of unwanted areas of a metal surface that are not protected by photoresist. Photo etching of metal that is exposed on both sides produces precision parts. Photo chemical machining that is only done on one surface of the metal and can form grooves, slots, bends, contours, embossing and precision engraving.

Photolithography

 A process used to create polymer forms. The process is based on selective radiation of light onto a photopolymer (a mixture of polymers, photo initiators and surfactants). The exposure process (polymerization), causes the production of polymer chains (matrices) thus transforming the material into a polymer. Photolithographic processes are applied in a broad range of industrial applications such as: semiconductor chip production and manufacturing printing plates for the print industry.

Photoresist

A mixture of prepolymers, photoinitiators and surfactants that react to light rays. Used in photolithography to selectively mask areas, a positive photoresist is soluble when exposed to UV light, and can be removed from the metal, exposing a copy of the mask. A negative photoresist is more difficult to dissolve because it withstands polymerization. Photoresist is used in cases such as: chemical etching, electroforming, selective surface treatments, and certain coatings.

Phototool

A template that defines the shape of the parts produced by the photolithography process. The phototool is made of glass, or a polymer slide, on which stroke marks or blacked out areas are printed to prevent light from coming into contact with the photoresist.

Stripping

A process that removes photo resist from metal.

Tabs or Tags

Pieces of metal that bond the precise metal parts to the substrate and/or to each other.

Tolerance

The digression that is allowed from the measurements specified in the blueprint.
