Company profile
Taiwan Air Water Mach Co. Ltd. is the Taiwan presence of AIR WATER MACH, a sealing and industrial-rubber-products business whose core company has operated for more than half a century and established a position in sealing-material development and manufacturing. AIR WATER MACH has expanded production bases domestically and overseas and established an integrated production system from design through packaging. In addition to standard O-RING products, it develops customized products to meet customer requirements, including the high-performance Pororoca brand, with sealing materials used to prevent liquid or gas leakage. Its listed sealing and industrial-rubber products include R.Pororoca O-rings for LCD and semiconductor process equipment, O-ring seals, R.Echo Perfluor FFKM products, fluororesin products, large-size O-rings, ferrule gaskets, and custom rubber molded products. Beyond sealing, AIR WATER MACH works on polyurethane injection-molded products, manufactures and sells bovine embryo-transfer devices in its animal-medical business, develops antibacterial and deodorizing agents, and continues research and development across these fields.
Exhibits
PTFE (PolyTetraFlouroEthylene) is an engineering plastic and a fluororesin known by the product name Teflon, with strong heat resistance and a low coefficient of friction among plastics; adding different fillers gives PTFE different characteristics. Glass-fiber-filled PTFE improves wear resistance, has strong resistance to acids and oxidizers with good chemical resistance, causes little loss of electrical properties, can be attacked by alkalis, and can be combined with graphite or molybdenum disulfide; carbon-filled PTFE improves wear resistance in air and water, resists deformation under high temperature and load, withstands corrosive environments, and is often combined with graphite. Graphite improves friction and wear behavior, reduces wear on mating metal parts, withstands corrosive environments, and can be combined with glass fiber or carbon; copper powder reduces deformation and increases compressive strength, dimensional stability, hardness, thermal conductivity, heat dissipation, and wear resistance, but its stronger chemical reactivity and electrical conductivity result in poorer chemical resistance and electrical insulation. Molybdenum disulfide is described as providing better deformation resistance, bending resistance, compressive strength, hardness, and wear resistance than glass fiber alone, with lubrication, lower wear, and a shorter initial wear period, and is recommended for use with glass fiber; carbon fiber can provide carbon- and graphite-like physical properties at low content, with tensile strength and elongation above carbon powder, improved wear resistance in air and water, resistance to deformation at room and high temperatures, and resistance to corrosive environments. Backup rings prevent O-RING extrusion and damage when fluid pressure is too high or groove clearance is too large, and even at lower pressures they can prevent scratches and twisting and extend O-RING service life; available shapes are uncut, trapezoidal-cut, and oblique-cut, with effectiveness ranked uncut above trapezoidal-cut above oblique-cut and installation easier for oblique-cut and trapezoidal-cut types. For backup-ring use, pressure from both sides calls for rings on both sides of the O-RING, one-direction pressure calls for a ring on the opposite side and, when space permits, two rings are recommended; various synthetic resins can be used but PTFE is common, trapezoidal-cut rings should be rotated toward the deeper groove, and the rings can be used with mineral-oil hydraulic fluids, liquid-type hydraulic fluids, synthetic hydraulic fluids, and most operating fluids. For reciprocating or rotary seals using nitrile-rubber or fluororubber O-RINGs with gear oil, turbine oil, gasoline, engine oil, or other organic solvents, a PTFE cushion-type seal can reduce sliding resistance, keep starting resistance largely unchanged after long stops, avoid friction-induced jumping, operate without lubrication, extend life, work up to 20MPa without a Backup Ring, and fit standard JIS O-ring grooves; the listed pressure range is below 20MPa with one RING per 7MPa, using copper-filled PTFE for reciprocating and helical motion, glass-fiber and molybdenum-disulfide-filled PTFE for rotary motion, and PTFE for general low-pressure use. V-shaped packing seals through internal pressure acting on its sealing lips against the shaft and inner wall, operates with low tightening pressure and low friction, and is offered in H, M, L, and D types; filled-PTFE V-packing is recommended for higher operating speeds because unfilled PTFE has excellent low friction but weaker wear resistance, with listed pressure ranges of 30~300, 20~70, 0~30, and 0~20 kg/cm2 and standard packing counts of 3~6, 3~6, 3~4, and 1~3 respectively. Adapter rings can be used against metal parts but preferably use the same material, springs can compensate for V-packing shrinkage under strong temperature changes, PV value must remain within its limit during operation, and rotary use requires cooling and consideration of frictional heat with metal gaskets recommended; PTFE lip seals are formed in U, L, and J shapes to resist corrosive liquids and solvents.
