Contract machining is a set of manufacturing operations or processes used for the fabrication and finishing of components for original equipment manufacturers (OEMs). These operations are used to manufacture production volumes ranging from prototype to high volume production runs. Some machining processes commonly used for contract machining are milling, turning, drilling, and electrical discharge machining (EDM). In many cases, contract machining is supported by design and engineering services as well as assembly services. Contract machining can be used for fabricating and assembling complete products or sub-assemblies.

Casting is a fabrication process to yield a manufacture of desired shape. The process is a sequence of steps with the primary move being the introduction of fluid melt into a mold followed by the hardening of the melt within the mold, and terminated with the ejection of the melt to unveil the fabricated part or casing. The process is governed by four crucial elements pattern, mold, part and the cores. The pattern, the original template whose design is duplicated in the mold, carves out an identical cavity in the casting material. Cores create holes or tunnels in the finished mold, which is the final outcome of the process.

CNC machining is any method of production that employs a computer numerically controlled (CNC) system to control the machining process via instructions (in form of alphabets, digits, and symbols) generated by a processor. A CNC program stores instructions for machining a part in a memory system or storage media. This machine control technique eliminates the need of human intervention to control and direct the machining operation. Point-to-Point, open-loop, continuous path, and closed loop control systems are some types of CNC systems commonly used. The process is widely used in metalworking operations to minimize the production cost of machined parts. Accuracy and repeatability, reduced set up time, and contouring of complex shapes are some other advantages of the CNC machining process.

Conveyors are mechanical devices used to transport parts, components, dry goods, and more. They are manufactured for a variety of applications such as material handling, manufacturing, and assembling. There are a multitude of conveying applications and conveyor types including pneumatic, bulk, material handling, industrial automation, bucket, vibrator, belt, slat, packaging, spiral, curved, incline, vertical, and elevators.

Centrifugal pumps (called C pumps) have a rotary motion of a profiled impeller in combination with a shaped pump housing to apply centrifugal force to discharge fluids from the pump. They operate most efficiently in high-volume, low-output-pressure conditions, and unlike positive-displacement pumps, the flow may be controlled allowing flow to be completely closed off while the pump is running.

Compression fittings are fixtures that operate by forming a taut seal, realized by the application of compressive force to the pipe fittings and pipes. A force adequate to remove the space existing in the joint in its entirety is exerted to compress the fitting against the pipe, whereby any risk of fluid leakage is eliminated. Fittings of this type are commonly used in plumbing to connect a pair of tubes or thin-walled pipes. These fittings are also used for connecting pipes of dissimilar material makes. These fittings are used in the construction of toilet stop valves, and hot and cold faucets.

Control valves are power-actuated devices operating in a process system as a critical component of a control loop, to alter the fluid flow rate. These valves maneuver a flowing fluid, such as steam, water, gas or chemical compounds, as compensation for load disturbance, and maintain the regulated process variable at a closest possible value to the pre-set value. Butterfly, gate or knife, needle, diaphragm, globe, pinch, ball and plug include some types of this class valves.

Compression springs are usually made from wire that is cylindrically coiled and as a result offers resistance to compressive forces. By designing springs with different wire sizes, coil spacing, and so on, common shapes such as conical, barrel, tapered, and hourglass can be manufactured. These springs offer a good resistance to linear compressing forces and are among components that efficiently store significant amounts of mechanical energy. They can be found in a wide variety of applications, for example, engines, suspensions, pens, and electronics.

Coil springs (also called compression springs) are mechanical devices that store energy and offer resistance to compressive force when applied axially. Common forms of coil springs are conical, tapered, concave and convex and they are typically made of an elastic material; such as alloy steel, plastic or rubber.

Check valves are one-way directional valves with fluid flowing in the proper direction opening the valve and reverse flow closing the valve. These mechanical valves have both gas and liquid applications.

A CNC machine shop refers to any workplace or area used for the fabrication, production, finishing, and repair of components using computer numerically controlled (CNC) equipment. A typical CNC machine shop or workshop will consist of machines that are controlled by a CNC system through instructions generated by a processor. As the CNC machines are fully automated, the number of operators required is comparatively less than machine shops with conventional machines. Where automatic loading and unloading equipment is used, CNC machine shops can operate unattended. High accuracy, increased production, low production time, and less labor intensity are some of the advantages of a CNC workshop environment.

A chiller is a cooling system that removes heat from one element (water) and moves that heat into another element (ambient air or water). The chiller is very similar to an air conditioning system in that it is compressor based but it cools liquid while an air conditioning system cools air. Other components are a reservoir, re-circulating pump, evaporator, condenser and a temperature controller.
