Titanium dioxide nanoparticles are predominantly used in sunscreen due to their ability to absorb and reflect UV radiation, protecting the skin from damage. They are also used in cosmetics, paints, and coatings for their ability to provide opacity and durability. Other applications include food additives, pharmaceuticals, and photocatalysis in solar cells due to their strong photocatalytic activity. Due to possible environmental and health risks, careful consideration and research is required during application.

Titanium was first used in the 19th century. It was first discovered in 1791 and first reduced to a metal form in 1825. The first widespread industrial use began in the 1940s and 1950s.

An injection blow molding machine combines injection molding and blow molding technologies for producing high-quality, seamless plastic bottles and containers. Initially, the machine injects molten plastic into a mold to form a preform. This preform is then moved to a blow mold where it is inflated into its final shape using pressurized air. This process is particularly favored for its precision, repeatability, and ability to produce products with uniform wall thicknesses. Injection blow molding is widely used in the pharmaceutical, cosmetic, and food beverage industries for its capability to produce containers with excellent clarity, rigidity, and barrier properties. By integrating both molding processes, manufacturers can reduce production time and costs, while ensuring high product quality and detail.
