In recent years, with the rise of outdoor sports, sports smart watches are becoming more and more popular. The major smart watch manufacturers not only innovate the movement function of the smart watch, but also try to make more materials of the watch. Titanium and titanium alloy are favored by the smart watch industry for their light weight, high strength, corrosion resistance, anti allergy, beautiful appearance and other properties.
 
Titanium injection molding technology began in 1988 and was applied in the mid-1990s. At present, pure titanium powder, Ti-6Al-4V, TiAl, Ti Mo Al and other titanium based materials have been successfully manufactured by injection molding process. Titanium MIM products have been used in golf head, auto car, medical machinery, dental implant, watch case, strap, buckle and other luxury products. Titanium MIM molding has the characteristics of easy control of alloy composition, high utilization rate of raw materials, simple production process and high production efficiency.

There are still many problems in MIM development of titanium and titanium alloy, mainly including:
 
Because of the high price of low oxygen spherical titanium powder and the pollution of oxygen, it is difficult to obtain nanometer titanium powder;
 
At present, EBS wax is the most practical one for binder selection and removal, but it needs to be removed in vacuum or argon environment with high cost;
 
Removal of interstitial elements, etc.
 
The preparation of low oxygen and low cost spherical titanium powder is the main development direction of titanium and titanium alloy powder. Among them, the titanium powder prepared by aerosol technology has small particle size, high sphericity, low oxygen content, large-scale production capacity and low cost, which is the main method to produce high-performance spherical titanium and alloy powder at present. At the same time, developing a new and efficient binder system for MIM of titanium alloy, optimizing the mixing, degreasing, sintering process and injection parameters are the key to preparing low-cost and high-performance titanium alloy injection molding parts.
