MIM technology is a very important molding technology in the medical device industry. Small medical devices, precision parts, high-precision parts, and high-performance parts are basically produced using MIM technology. It is also very cost-effective for the production of complex precision parts. Common MIM medical instruments include ear parts, hemostatic forceps, laparoscopes, scalpel handles, dental parts, forceps, scissors, orthopedic joint parts, etc. The current trend in the medical industry is minimally invasive surgery and minimally invasive plastic surgery. Many medical device parts that need to be used are produced by MIM technology. Minimally invasive MIM surgical parts have various geometric shapes and complex structures, which require very high dimensions and accuracy. At present, stainless steel, titanium and nickel-titanium alloys are widely used, and MIM technology is used for dental implants.
The automotive industry has become a major application area for MIM parts, such as numerous MIM auto parts with complex shapes used in engines, gearboxes, turbochargers, locking mechanisms, steering systems and electronic systems. Such as 1) The rocker arm of the BMW engine. One is a rocker arm that rotates with the rollers. This is a rocker arm made of low alloy steel that controls the variable valve timing travel of the engine. It is characterized by its hollow structure and light weight, which is difficult to make by other methods; (2) Shift lever. This is a very high volume MIM custom parts for manual transmissions in passenger cars. The production process of this part is: injection molding, sintering, hardening and assembling the shaft. The material used is Fe2Ni, and the parts should be carburized and quenched after sintering; (3) Turbocharger blades. The production of such MIM variable area nozzle
becoming more sophisticated and complex. In this context, the application prospects of the MIM process are becoming increasingly clear. At present, the process has been widely used in the manufacture of MIM communication parts such as card trays, camera rings, buttons, connector joints, built-in structural parts, watch cases, and buckles.
Orthodontics include a wide range, usually refers to the treatment process of correcting misaligned teeth, abnormal tooth morphology, and abnormal tooth color through oral technical means. There are various methods of orthodontic treatment, such as resin veneer, porcelain veneer, porcelain teeth, orthodontics, etc., according to the actual situation of the individual's teeth, the type of dental deformity, etc., and then choose the treatment method based on individual requirements. Each has its own advantages and disadvantages, and different people have their own preferences. It is necessary to communicate directly with the doctor during the examination to determine the plan. Mainly divided into functional correction and aesthetic correction. Depending on the type of disease, the clinical manifestations are also different, and the common feature is that it has a negative impact on the appearance. Misaligned teeth are manifested in the in and out of the teeth, the overlapping of the teeth, etc., making the teeth difficult to clean and susceptible to dental disease. Abnormal tooth morphology is manifested in incomplete tooth defect, disproportion with adjacent teeth, affecting chewing and image. The most common types of tooth discoloration are fluorosis and tetracycline. The treatment principle of orthodontic treatment is to meet the aesthetic needs while maintaining the complete structure of the tooth tissue to the greatest extent, protecting the health of the gums; enhancing the health, function and aesthetics of the oral cavity, improving the patient's acceptance of oral treatment, and enhancing their confidence. The main methods include resin veneer, porcelain veneer, porcelain teeth, orthodontics, etc., or the use of dental orthodontic brackets. It is necessary to fully consider the patient's age, requirements, degree of injury, treatment time, and expected effects. choose.
