Some of the considerations for raw material selection include impact strength, high and low temperature characteristics, wear resistance characteristics, machinability, and hardness requirements.
These are metal alloys consisting of a mixture of nickel and iron. Iron-nickel alloys have special magnetic properties that vary with the amount of nickel. These alloys cannot be hardened by thermal treatment, only though cold work. Iron-nickel alloys have poor machinability characteristics.
Carbon steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable under suitable conditions and distinguished from cast iron by its malleability and lower carbon content.
Nickel steel is a steel containing nickel as an alloying element. Varying amounts of nickel are added to increase the strength in the normalized condition and to allow for hardening to be performed in oil or air instead of water.
Stainless steel is a wide variety of chemical and corrosion resistant steels which contain a high percentage of chromium. Stainless steel is resistant to corrosion by weak mineral acids, organic acids, and atmospheric oxidation.
Superalloys are nickel, cobalt, or iron-base alloys designed for very high temperature applications where relatively high stresses (tensile, thermal, vibratory, and shock) are encountered and where oxidation resistance is frequently required.
Titanium alloys contain alloy additions of aluminum, manganese, tin, or vanadium, which strengthen the titanium matrix. They cannot be hardened through any heat-treating process, but can be hardened by cold work. During machining, titanium alloys have a tendency to gall or weld themselves to the cutting tools. This can be resolved with the proper coolant.
Tool steel is a generic term for a wide range of both carbon and alloy steels. They are used for surfaces that must hold an edge or have good wear-resistance characteristics. Tool steel applications include cutting tools, press tools, hand tools, molds for plastics and die-casting, and extrusion tools.

With design assistance, suppliers can assist with concepts, manufacturing costs, manufacturing techniques and material considerations. Suppliers may also be able to assist in upgrading or redesigning, re-evaluating or modernizing existing products to increase performance and/or reduce manufacturing costs. Some suppliers offer material sourcing and CAD modeling as well.
Suppliers can mold-in or mold-on graphics such as company logos, warning labels, and instructions. Mold-in graphics incorporate a decal into a molded part. The decal is applied to the mold surface and becomes integral to the molded component. Mold-on graphics can be applied after the part is molded.
The powder metal (P/M) process uses pressure and heat to form precision parts and shapes. The process begins by filling a die with powder and then compacting it at room temperature to form an engineered shape like a gear. Next, this compacted shape is ejected from the press and fed through a high-temperature furnace. This process, called sintering, metallurgically fuses the particles without melting them. After sintering, there are a variety of secondary operations that can be performed, including: sizing, plating, coining, CNC machining, CNC turning, ID/OD grinding, surface grinding, tumbling, drilling, tapping, heat treating, steam treating, and impregnation.
Thixoforming is a process of manufacturing components from a semi-solid, heated metal. The semi-solid metal is injection molded to form complex, high-density parts. Thixoforming yields stronger parts than those made with conventional die-casting.
Micro molding uses special miniature molding machines to produce very small parts that typically weigh less than two grams. Micro molding serves a variety of industries and is used in medical, automotive, and consumer electronics applications.
Heat treating is a broad category of metal treating processes such as annealing, passivating, hardening, etc. Stress relieving may be important to relieve residual stresses imposed during the stamping process.
Suppliers provide secondary operations and assembly services such as electro-mechanical assemblies, ultrasonic and heat welding, printing, painting, bonding, and machining.
Polishing, buffing, and belting processes are abrasive, metal smoothing operations that change the surface appearance of the metal. These operations can be for aesthetic and/or functional purposes.
Suppliers provide packaging and shipping capabilities including bulk shipments for further processing or final packaging and shipping of products or devices directly to the individual end customer.
Suppler offers training in the Metal Injection Molding (MIM) process.

AS 9100 is an expanded, international version of AS 9000, a standard which defines quality system requirements for suppliers to the aerospace industry. AS 9100 was developed by major aerospace manufactures in conjunction with the ISO Aerospace Technical Committee (TC) 20, and published by the Society of Automotive Engineers (SAE).
ISO 9001:2000 establishes requirements for company quality management systems. Standards range from manufacturing to services such as design, development, production, and installation.
ISO 13485:2003 specifies quality management system (QMS) requirements for organizations that need to demonstrate their ability to provide medical devices and related services that consistently meet applicable customer and regulatory requirements. ISO 13485:2003 contains specific requirements for medical devices and excludes non-applicable requirements from ISO 9001. Consequently, an organization with a QMS that conforms to ISO 13485:2003 cannot claim to conformity to ISO 9001 unless the QMS meets all of ISO 9001’s requirements.
ISO 14001 specifies the actual requirements for an environmental management system. It applies to those environmental aspects, over which the organization has control or influence. ISO 14001 was first published in 1996 and is the only ISO 14000 standard against which it is currently possible to be certified by an external certification authority.
ISO/TS 16949:2002 is an ISO Technical Specification that aligns existing American (QS-9000), German (VDA6.1), French (EAQF) and Italian (AVSQ) automotive quality systems standards for the global automotive industry.
QS 9000 is a quality standard for suppliers of DaimlerChrysler Corporation, Ford Motor Company, and General Motors Corporation. QS-9000 is based on the 1994 edition of ISO 9001, but contains additional requirements that are particular to the automotive industry. Specifically, QS 9000 applies to suppliers of production materials, production and service parts, heat treating, painting and plating, and other finishing services.
