SEMIFINISHED PART
Manufacturing
Semi-finished contacts are a preliminary step in the manufacturing of contact parts. Technical and economic aspects determine the manufacturing technology to be used. Mechanical, electrical, thermal, electro-thermal, as well as physical processes are applied to blend materials with sometimes very different physical and technological properties.
Semi-finished products with aluminum cladded surfaces and
the punched parts manufactured from them are used in hybrid housings for electronic
applications. At the interface between electromechanical connectors and
electronic subassemblies, aluminum is used as a bondable surface. Semi-finished
products with selective solder layer are the basic product for safety fuses.

CUSTOM
PART
Manufacturing
(New Definition - Better):
A
custom part is designed and manufacturing for a specific purpose in a specific
product or product line rather than for generic purpose in several different
products. Custom parts that are incorporated into the subassemlies and
assemblies of products and machines are often referred to as piece parts. Custom
parts that stand alone as products are referred to as single-part products.

Answer)
Custom components,
which are parts designed especially for the product, are made by the
manufacturer or by a supplier. Most custom components are produced using the
same types of production processes as standard components (e.g., injection
molding, stamping, machining); however, custom parts are typically
special-purpose parts, useful only in a particular manufacturer’s product.

S.R.,Manufacturing engineering and technology, 5th Edition, p. 217)
STANDART PARTS
Manufacturing
Parts are either standard or special
purpose. A standart part is a member of a class of parts that has a generic
function and is manufactured routinely without reference to its use in any
particular product. Excamples of standard parts are screws, bolts, rivets, jar
tops, buttons, most beams, gears, springs, and washers. Tooling for standard
parts is usually on hand and ready for use by manufacturers. Manufacturers,
dşstrubuters or vendors often carry standard parts themselves in stock.
Standard parts are most frequently selected by designers from catalogs, often
with help from vendors.
