Sihai supplies aerosol can cone and dome components across multiple models and diameters, matched to the can body formats we produce and to the assembly requirements of our customers. Each set pairs a cone (top) with a corresponding dome (bottom) to ensure dimensional compatibility, secure valve seating, and reliable pressure performance.
Manufactured by Guangdong Sihai Iron-Printing and Tin-Making Co., Ltd., these components are produced in-house on fully automated pressing lines. They are available with internal coating or without, and with clear (varnish), white, or gold lacquer finishes. Components can be supplied as part of a complete can or as standalone parts for customers who handle their own can assembly.
