Swiss machining is a type of machining accomplished through a swiss machine, which is an automatic lathe featuring a guide bushing and a sliding headstock. The material that is to be shaped and the tool can be moved simultaneously, which helps in carving the material into shape. Sophisticated machining of this genre benefices from computer numerical control, which helps manufacture high-precision components and yields high productivity. Some of the major parts that are machined by a swiss machine are miniature screws, contact pins for electronics components, grommets and bobbins.

Stock shapes are standard aluminum extrusions already manufactured and available from stock in different diameters and sizes. Examples include bars, rods, I-beams, T-slots, elbows, pipes, tubes, etc.

Sand casting is a process to manufacture rough metal castings by pouring molten metal into a natural or a fabricated sand mold. The four main decisive elements in the casting process are patterns, chills, cores, and molding box and materials. The sand used in the process is amenable to repetitive recycling and necessitates only minute supplements. The sand mold is time-effective as it can be swiftly carved; it avails of the pattern to carve out the casting template. Low-temperature iron, aluminum, magnesium, and nickel alloys are some of the castable metals.

Silicone gaskets are seals created from an uncured blend of a compound of silicone which is exercised over the mating parts and this assembly is subjected to curing process. These gaskets are versatile and are available in myriad material varieties such as thermally-conductive silicones, reinforced silicones, electrically-conductive silicones and high tear strength silicones. Gaskets of this type are widely used in applications that demand resistance to extreme temperatures since they exhibit a tendency to operate at high temperatures. They are also used to shield processor chips and circuit boards from heat, dust, moisture and various fluids.

A silicone O ring offers excellent resistance to extreme temperatures, ranging from -150°F to +500°F, for various sealing applications. Silicone rubber is a polymer made from the amalgamation of silicon with hydrogen, oxygen, and carbon. Its high resistance to extreme temperatures makes it a perfect O-ring recommendation for applications that involve high and low dry heat temperatures. However, its poor tensile strength and susceptibility to tearing and abrasions, has made it unsuitable for dynamic sealing applications. In addition, silicone O rings are also incompatible with most petroleum oils and ketones. Despite this, silicone rubber's exceptional resistance to extreme temperatures makes it ideal for static sealing operations in food processing applications.

Shock absorbers, and its related products, vibration mounts, vibration isolators, and vibration dampeners, are rubber mountings that have been engineered to restrict the transfer of shocks, vibration and sound while maintaining support of a structure and allowing relative motion between that structure and the vibrating object.

Submersible pumps can be totally submerged in the media that they are pumping. The pump's motor is sealed in an oil filled cavity that is protected from contact with the liquid.

Spiral wound gaskets are mechanical seals formed by spirally winded metal strip and a filler material soft of nature on the periphery of the mandrel. Gaskets of this type are dependent on the mechanical properties of the produced metal spiral strip rather than the compressive properties as is the case with conventional gaskets, which makes these gaskets ideal for fluctuating or low bolt loads. Their high tolerance for extreme pressure and temperature makes these gaskets an ideal component in applications involving high variations in pressure and temperature. They are also functional as static sealing element in pumps, thermal exchanges, valves, pipes and other parts. Industries of application include manufacturing, nuclear energy, petrochemical and pharmaceutical.

Sewage pumps are used to pump effluents, semi-solids and small solids suspended in liquid.
