Abstract
A method of encapsulating an article such as an electric part is disclosed which includes the steps of: (a) powder coating the article with a thermosetting resin powder coating composition to form a melted layer of the thermosetting resin composition around the article; (b) molding the melted layer of the thermosetting resin composition obtained in step (a) in a mold under pressure while maintaining the mold at a temperature lower than the softening point of the thermosetting resin composition, so that a solidified, molded layer of the thermosetting resin composition having a predetermined shape is formed around the article; and (c) heating the solidified layer obtained in step (b) to cure the thermosetting resin.
Claims5
A method of encapsulating an article, comprising the steps of:
- (a) powder coating the article with a thermosetting resin powder coating composition to encapsulate the article with a melted layer of the thermosetting resin composition;
- (b) molding the melted layer of the thermosetting resin composition obtained in step (a) in a mold of predetermined shape under pressure while maintaining the mold at a temperature lower than the softening point of the thermosetting resin composition to mold said coating to said predetermined shape, thereby forming a solidified, molded layer of the thermosetting resin composition having a predetermined shape formed around the article;
- and
- (c) heating the shaped solidified layer obtained in step (b) to cure the thermosetting resin.
