摘要： A method and apparatus for making insignias with a raised design is capable of providing more aesthetic appearance to the insignias thus made. A base material consisting of a base sheet and a surface sheet overlaying the base sheet is prepared for making into an insignia. The base material is coating with a surface coating of decorative material. A bottom mold and an upper mold are used to press the base material to form raised design of patterns. The bottom and upper molds are coupled to a composite heating device including high-frequency induction and electric heating means for applying both high-frequency induction heat and electric heat to the base material while the upper molding is being pressed against the bottom mold. The upper mold is formed with a plurality of edge-defining blades for cutting an edge for the insignia, a plurality of pattern-defining blades for forming a pre-designed pattern on the insignia. During the pressing, the composite heat is concurrently applied to the upper and bottom mold so as to cut and melt away part of the surface sheet to form the pattern. The remnants cut away by the pattern-defining blades can be easily removed by brushes. The final product is an insignia with raised design of patterns with shining appearance.

摘要翻译： 用于制造具有凸起设计的徽章的方法和装置能够为这样制作的徽章提供更美观的外观。 制备由基片和覆盖基片的表面片组成的基材，制成徽章。 基材是用装饰材料的表面涂层涂覆的。 使用底模和上模来按压基材以形成凸起的图案设计。 底模和上模耦合到复合加热装置，该复合加热装置包括高频感应和电加热装置，用于在上模具压靠底模的同时将高频感应热和电热施加到基材。 上模具形成有用于切割徽章的边缘的多个边缘限定刀片，用于在徽章上形成预先设计的图案的多个图案限定刀片。 在压制过程中，将复合热量同时施加到上模和下模上，以切割和熔化部分表面片以形成图案。 由图案定义的刀片切掉的残余物可以通过刷子容易地去除。 最终产品是具有凸起外观设计的徽章。
