MIM technology can also be used to produce components for various medical devices.

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. uses MIM technology to produce a hearing aid sound tube for a German company, which has the effect of increasing the sound rate and promoting hearing.

The sound tube has a density of more than 7.65 g/cm3, a maximum tensile strength of 480MPa, a yield strength of 150MPa, an elongation of 45%, and a maximum surface hardness of 100HRB. MIM technology can reduce the cost by 20% compared with the previous traditional production process.

MIM technology can also be used to produce many medical products, including interventional stents, radiation shielding for tungsten high-density alloy syringes, microsurgical manipulators, micro-pump endoscope parts and drug inhalers.

For more than 70 years, Phonak Hearing (Sonova Hearing Technology (Shanghai) Co., Ltd.) has always adhered to the concept of innovation, committed to R&D and innovation, and provided hearing solutions to customers around the world. Zhongwei Precision has cooperated with Phonak Hearing for 5 years to provide titanium alloy hearing aid shells, hearing aid tubes and other components. Phonak Hearing's unique full-time sound tracking system (AutoSense OS) allows hearing aid products to be used in different sounds. Automatically switch the listening mode under the environment; our lithium-ion rechargeable hearing aids let users say goodbye to the trouble of battery replacement; for the first time, we applied titanium alloy and titanium metal injection molding MIM technology to in-the-ear hearing aids, defining a new type of in-the-ear hearing aids. Benchmark. The innovative MFA (Made For ALL) wide-area compatible technology, directly connected to Apple, Android and most smartphones, defines a new standard for wireless Bluetooth hearing aids. Biometric verification technology effectively improves the accuracy and precision of sound capture and transmission, which is a new sublimation of customized hearing aids. At medium and long distances beyond the reach of hearing aids, we also have the RogerDirect and AirStream transport protocols to make conversations seem like they're close at hand.
