electroforming उदाहरण वाक्य

उदाहरण वाक्य

1. Cut " wax " sound discs would be placed in a vacuum chamber and gold-sputtered to make them electrically conductive for use as mandrels in an electroforming bath, where pressing stamper parts were made.
2. "' Electroplating "'is a process that uses electric lubricity, aesthetic qualities, etc . ), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
3. Targray has sold materials used in the fabrication of optical discs and DVDs since it was founded in 1989 . The company is a global supplier of mastering, replication and electroforming materials used in the manufacturing of optical media products.
4. This is done with relative ease because no actual " plating " of the mandrel occurs in the type of electrodeposition known as electroforming, unlike with electroplating, in which the adhesion of the new phase of metal is chemical and relatively permanent.
5. In the vinyl record manufacturing process, an acetate master disc is cut and electroforming is used to make negative metal molds from it; each mold, known as a stamper, can be used to press thousands of vinyl copies of the master.
6. The " sons " are then converted into " stampers " by center-punching a spindle hole ( which was lost from the lacquer sound disc during initial electroforming of the " father " ), and by custom-forming the target pressing profile.
7. Producing mothers was similar to electroforming Masters, except the time allowed to turn-up to full current was much shorter and the heavier Mothers could be produced in as little as one hour and stampers ( 145 grams ) could be made in 45 minutes.
8. Home to the National Liberty Museum ( featuring all exhibits by international glass artists ), Philadelphia hosts the non-profit P . I . P . E . program, with residencies for artists that use glass as well as metal, electroforming on glass, and bronze casting.
9. The " sons " made during a " three-step " electroforming make better stampers since they don't require silver removal ( which reduces some high fidelity because of etching erasing part of the smallest groove modulations ) and also because they have a stronger metal structure than " fathers ".
10. The metal stamper first struck from the metal-coated glass is the metal master ( and we shouldn't make a master from another master as that would not follow the nomenclature of the sequence of siring that is germane to electroforming ) This is clearly a method opposite to normal electroplating.
