Estimating the term…
The article and corresponding method include a casting fixture for a part of a skin formulation applicator which is otherwise difficult to cast. The casting fixture includes a central cup section and two opposing tear-away sections. A rigid base portion of an applicator tip assembly is mounted into an upper rim of the cup section and liquid silicone material is poured into the volume defined in the cup section portion beneath the base portion. The silicone cures and bonds to extending elements from the base portion, providing a firm connection between the cast tip portion and the base portion. When the combined part is ready for use, the tear-away sections are removed by the user, which results in an easy ejection of the part, which can then be installed by the user in the formulation applicator.
An article for casting parts, comprising:
A method for casting a tip portion of a tip applicator assembly used in a skin formulation applicator, wherein the tip portion is mated with a base portion of the tip applicator during casting, the method comprising the steps of:
The method of clam 11, wherein the casting fixture includes two tear-away sections extending from opposing ends of the cup section.
