一种大面积3D线圈产品的制作方法及3D线圈产品
摘要：
一种大面积3D线圈产品的制作方法，包括以下步骤：a.将用于制作线圈的金属材料成型为锅状的3D曲面金属件；b.在所述3D曲面金属件的一侧一体注塑成型注塑件；c.将所述3D曲面金属件加工成在所述注塑件的表面多圈环绕分布的线圈；d.在所述线圈上进行二次注塑以将所述线圈覆盖，仅露出作为线圈正负极的两个触头。一种大面积3D线圈产品，包括整体轮廓为锅状的多圈环绕分布的3D线圈及与所述3D线圈一体注塑成型的注塑材料部分，所述注塑材料部分将所述3D线圈包覆在内部，仅将所述3D线圈的正负极的两个触头露出。本发明的3D线圈产品有效加热面积大，效率高，加热均匀。
摘要（英）：

A manufacturing method of a large-area 3D coil product includes the following steps that a, metal materials used for manufacturing a coil are shaped into a pot-shaped 3D curved-surface metal part; b, an injection molding part is formed integrally on one side of the 3D curved-surface metal part in an injection molding part; c, the 3D curved-surface metal part is machined into a coil wound on the surface of the injection molding part by multiple circles; and d, secondary injection molding is carried out on the coil to cover the coil, and only two contacts of the positive electrode and negative electrode of the coil are exposed. The large-area 3D coil product comprises the 3D coil which is pot-shaped in overall outline and distributed in a multi-circle winding mode and the injection molding material part integrally formed along with the 3D coil in an injection molding mode. The 3D coil is wrapped inside the injection molding material part, and only the two contacts of the positive electrode and negative electrode of the 3D coil are exposed. The 3D coil product is large in effective heating area, high in efficiency and uniform in heating.
