Extension springs are mechanical devices that store energy and offer resistance when subjected to external forces. Extension springs work by resisting a load which stretches the spring and makes the spring longer. They are attached at both ends to other components and as the components move apart, the spring pulls them back together.

An eyelet is a small metal ring with an integrated flange, made by metal stamping, that is inserted into a hole to provide reinforcement to it. In some cases the eyelets are provided to cover the sharp edges of the holes and protect them. Some of the materials used to make eyelets are plastic, copper, stainless steel, aluminum, and brass. They are commonly used to reinforce holes in various materials, including leather, paper, and various other fabrics.

EDM machining is a method that utilizes an extremely slender wire as an electrode in the process of shaping hard metals that exhibit electrical conductance. Electrical discharge machining carves out the metal shape by bordering out scrap through the rapid generation of contiguous electrical discharges that journey between the metal being machined and the electrode. The wire is introduced into the material slowly and the cutting is, in reality, accomplished by the discharges. The required shape takes form by the production of deeper craters in the target piece ensuing the recurring discharges. The wires serving as electrodes are typically made of special brass.

An electrical enclosure is any cabinet or box utilized for the mounting of electronic or electrical equipment, such as knobs, switches, and various other electrical components. Electrical enclosures are fundamentally used to protect users from electrical shocks as well as shield the contents of the enclosure from the environment. These enclosures are generally made from rigid plastic or metals, such as aluminum and steel. In some cases, wood cabinets are also used.

An encapsulated gasket is a specialized type of gasket that consists of soft elastomeric material at the core, which is encapsulated by another material that imparts resistance to chemicals and temperature. These gaskets combine the superior sealing performance of the core gasket materials and chemical resistance of the encapsulate material to offer a superior seal. Some of the commonly used encapsulate materials are polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), and Teflon. In addition, graphite or Thiokol rubber are some of the commonly used gasket cores. Encapsulated gaskets are used in engine head gaskets, as well as heat exchangers and pipe flanges used in the petrochemical industry.

Exhaust hose is a fluid-transporting pipe contrived to carry hot compressed air into the external atmosphere even while withstanding high temperature. Special synthetic rubber is specifically used for heat resistance. The heavy wall thickness accounts for the long period of the hose. These hoses are familiar in fuel tank vent, fuel filler neck and wet exhaust type hoses. They are also commonly used in vans, heavy duty as well as light trucks, passenger cars, vans and buses.

Electro Chemical Machining services is a mode of metal machining using electrolysis techniques, purported for etching or creating unstressed, high-precision parts. A pre-shaped tool induced with reverse of the required detail, is introduced as cathode while the actual work piece is installed as the anode. A direct current of low voltage and high amperage is passed between the work piece and tool. Metal at the anode's surface gets ionized and the tool is gradually descended while maintaining its distance from the work piece constant. ECM is used for etching and milling of numerous components including exotic metals and alloys, silicon, ferrous and nonferrous metals, quartz, glass and stone.
