When it comes to dental and medical uses, accurate screws are what separate us from failure. OEM titanium screws for medical and dental equipment are the best example of safe engineering because they are very strong and don't rust like other materials. These titanium alloy bolts are reliable, which is what healthcare workers need. They also keep patients safe because they are not magnetic and have a strong structure. These high-performance materials are used by medical device makers all over the world for everything from tooth repair systems to hip implants.
Why Focus on Titanium Fasteners for Marine Applications?
Based in Baoji City, China, which is known as the "City of Titanium," Chuanglian has more than ten years of experience handling titanium for the medical field. We know everything there is to know about processing lightweight materials, from the raw metal to finished threaded screws. We can make things with more than a dozen CNC machines that are especially set up for medical-grade accuracy. To keep the tight limits needed for medical uses, every piece of equipment is calibrated on a frequent basis. High-tech equipment and trained workers work together to make sure that the quality of every production run is the same. Quality control is the most important part of what we do.
At every step of the production process, from receiving the raw materials to putting them in the boxes, we follow strict checking rules. Our quality system includes AS9100 aircraft standards and ISO9001 approval, which gives medical device makers the tracking they need. Our new surface cleaning methods come from research and development. Our team is always looking for new ways to improve the mechanical qualities of our screws by anodizing and nitriding them. This ongoing investment makes sure that our clients get the most up-to-date answers for their toughest problems.
Selection Criteria for Marine Titanium Bolts
Material choice is the first step in customizing a physical form. You can choose from pure titanium and titanium alloy bolts. For medical uses, Grade 5 (Ti-6Al-4V) is the most popular choice. The tensile strength of this metal is up to 900 MPa, and it is also very biocompatible. Standard sizes that we can thread range from M2 to M36, and we can also make unique threading designs for specific uses. Our CNC-made accuracy makes sure that every time you need micro-screws for delicate dental work or bigger fixings for orthopedic uses, they will fit perfectly. There are different ways to treat the surface, such as grinding for smooth tissue contact, anodizing for better rust protection, and nitriding for better wear qualities.
You can choose from a natural titanium finish or a gold, blue, green, purple, black, or rainbow coating. Each color serves a different purpose, such as identification or function. Branding and marking options let you laser etch part numbers, batch codes, or business names right onto the screws. This trait of tracking is very important for keeping records on medical devices and for return processes. Customized packaging makes sure that your screws come ready to be put together the way you want them to be. To make your manufacturing process run more smoothly, we offer clean wrapping, anti-static cases, and unique labels.
