Additional Services

Castle’s additional processing services include:

• Bar Coding

  A method of encoding data on products for fast and accurate electronic readability, which can be read by electronic readers, and used to facilitate timely and accurate input of data to a computer.

• Chamfering

  The process in which a flat surface is made by cutting off the edge or corner metal or other material.

• Chrome Plating

  A complex process used for both cosmetic and functional purposes for long wear life for component or production parts wherein a thin plate of chromium deposited by electrolysis on a corrodible metal, giving a bright, metallic surface which is highly resistant to tarnish. It provides lubricity and a surface hardness and is crack-free and both corrosion and heat resistant.

• Demagnetizing

  A procedure that reduces the magnetic flux to virtual zero by applying a reverse magnetizing field.

• EDI ANSI X12

  Following the ANSI X12 standards that define the structure, format, and content of business transactions, Castle uses EDI ANSI X12 to transmit business transactions such as such as orders, confirmations and invoices, from one company's computer to another company's computer. Transmission is achieved through an electronic communication network that uses translation software to convert transactions from a company's internal format to a standard EDI format.

• Flattening

  The process in which a series of staggered rolls of small diameter is used to remove bow and waves from sheet. While passing through the roll, the sheet is bent back and forth slightly and is delivered approximately flat.

• Forming/Drilling/Machining

  Forming:

  The process in which a machine press shapes a metal work piece by applying pressure on it.
  

  Drilling:

  The type of machining used when smaller holes are needed and a closer ole diameter tolerance is preferred or required. However, it is the slowest of the drilling operations and hole drift is typically greater than .001 per inch of length drilled.
  

  Machining:

  The process to remove excess or unwanted stock by the use of machine tools for rough or finish turning, boring, drilling, or milling.

• Heat Stamping

  A metal stamping process in which the work piece is heated.

• Line Marking

  The process of placing a distinct sign or image upon or within an object or material for identification or other purposes.

• Packaging

  The process in which we provide protective packaging material used to protect products throughout the entire transportation and distribution environment.

• Shot Blasting

  Cleaning surface of metal by air blast, using metal as a result of solidification shrinkage and the progressive freezing of metal towards the center.

• Skiving and burnishing

  A method of removing material from the inside diameter of a tube using a cutting tool moving into the ID followed by a roller burnisher to greatly improve the surface finish in one pass.

• Straightening

  Metal forming in which a bend is removed from a piece of metal by applying a force. Metal straightening is the opposite of metal bending.

• Trepanning/Boring/Honing

  Trepanning:

  A type of machining performed on solid material whereas, a hole is cored through the part. The end product is normally a heavy-wall tube or "hollow bar." Trepanning is a "coring" operation as opposed to other methods of producing a hole. The cutting tool cuts out a channel along the circumference of the hole, allowing the inner portion of the hole to remain intact. This solid portion is extracted after the hole is completed.
  

  Boring:

  A process that removes stock metal from the inside diameter which provides good, comprehensive geometry covering ovality, roundness and straightness.
  

  Honing:

  A process using abrasive polishing stones, this operation removes small amounts of materials to achieve precise Ids and improve finishes. Normal stock removal is .006" to as much .125" depending on the bore size of the tube. Other machining processes precede honing when larger amounts of materials need to be removed.
