Medical Device Couplings Machining Capabilities
The exacting Swiss turning, thread grinding, and machining to create grooves for sealing, electropolishing to create threads that engage and for surfaces to be biocompatible, and thorough leak testing, along with dimension verification, complete each coupling. Each coupling is composed of medical-grade stainless steels (303, 316L, 17-4 PH), titanium alloys (Ti-6Al-4V), brass, medical-grade plastics (PEEK, polysulfone), and alloys that provide exceptional biocompatibility in addition to corrosion resistance during multiple sterilization cycles and clinical use.

Materials for Medical Couplings Components

High machinability and ductility. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance.

Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished. The hardness and the cost of stainless steel is higher than that of aluminum alloy.

Steel is a strong, versatile, and durable alloy of iron and carbon. Steel is strong and durable. High tensile strength, corrosion resistance heat and fire resistance, easily molded and formed. Its applications range from construction materials and structural components to automotive and aerospace components.

Titanium is an advanced material with excellent corrosion resistance, biocompatibility, and strength-to-weight characteristics. This unique range of properties makes it an ideal choice for many of the engineering challenges faced by the medical, energy, chemical processing, and aerospace industries.

Highly resistant to seawater corrosion. The material’s mechanical properties are inferior to many other machinable metals, making it best for low-stress components produced by CNC machining.

Brass is mechanically stronger and lower-friction metal properties make CNC machining brass ideal for mechanical applications that also require corrosion resistance such as those encountered in the marine industry.

Few metals have the electric conductivity that copper has when it comes to CNC milling materials. The material’s high corrosion resistance aids in preventing rust, and its thermal conductivity features facilitate CNC machining shaping.

Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed.

Iron is an indispensable metal in the industrial sector. Iron is alloyed with a small amount of carbon – steel, which is not easily demagnetized after magnetization and is an excellent hard magnetic material, as well as an important industrial material, and is also used as the main raw material for artificial magnetism.

Due to the low mechanical strength of pure magnesium, magnesium alloys are mainly used. Magnesium alloy has low density but high strength and good rigidity. Good toughness and strong shock absorption. Low heat capacity, fast solidification speed, and good die-casting performance.
