1. Material Selection and Processing Technology

Metal Materials

Material Selection: Metals such as stainless steel and copper with certain corrosion resistance and good thermal conductivity are usually chosen. The purity and quality requirements vary for different metal materials. For example, high-quality stainless steel can ensure the durability and stability of the cocktail shaker, avoiding issues like rust or deformation during use.

Processing Technology: Metal cocktail shakers generally undergo multiple processes including cutting, forming, grinding, and polishing. Cutting involves trimming the metal material to the desired shape and size according to the design requirements. Forming processes include forging, stamping, stretching, etc., to transform the metal blank into the basic shape of the cocktail shaker. Grinding removes surface burrs and imperfections, making the surface smooth and flat. Polishing further improves the surface finish, enhancing its aesthetics and touch.

Glass Materials

Material Selection: It's necessary to select glass raw materials with high transparency, no impurities, and good chemical stability to ensure the quality and safety of the cocktail shaker. High-quality glass raw materials can guarantee that the cocktail shaker will not release harmful substances during long-term use and can also present good visual effects.

Processing Technology: The production of glass cocktail shakers mainly involves blowing, pressing, drawing, and other processes. Blowing is one of the most common processes, in which the glass liquid is blown into the desired shape through a blowpipe. This process can produce various complex shapes and designs. Pressing involves placing the glass liquid into a mold and applying pressure to form it, suitable for making some cocktail shakers with regular shapes and uniform thickness. Drawing involves stretching the glass liquid at high temperatures to form long glass tubes or rods, which are then further processed into various parts of the cocktail shaker.
