Manufacturing method for in-mold injection 3D coil product and 3D coil product

Abstract

A manufacturing method for an in-mold injection 3D coil product comprises the following steps that a, a metal material is machined to form a 3D coil, the overall contour of the 3D coil is in a pot shape, and multiple circles of wires of the 3D coil are distributed in a surrounding mode; b, an injection molding piece is formed on one side of the 3D coil through integrated injection molding; and c, secondary injection molding is conducted on the 3D coil to cover the 3D coil, and only two contacts of the positive pole and the negative pole of the coil are exposed. The in-mold injection 3D coil product comprises the 3D coil with the overall contour being in the pot shape and the multiple circles of wires distributed in the surrounding mode and the injection molding material part which is integrally formed with the 3D coil through injection molding, the injection molding material part wraps the 3D coil, and only the two contacts of the positive pole and the negative pole of the 3D coil are exposed. The effective heating area of the 3D coil product is large, efficiency is high, and heating is even.

Description

technical field [0001] The invention relates to a method for making an in-mold injection molded 3D coil product and the 3D coil product. Background technique [0002] Electrical products are more and more widely used in our lives, and people's improvement of the quality of life has promoted the development of electrical products. The heating coils of ordinary electrical products generally have the disadvantages of uneven heating and incapable of precise temperature control. The traditional 2D coil heating method will lead to high heat loss. For example, the traditional electric heating pan heats the bottom of the inner pot, and the heat is conducted from the bottom to the upper part through contact conduction. The disadvantages of this are slow heating, uneven heating, and more Not to mention smart and precise control of heat, air pressure and moisture. In addition, another big disadvantage of resistance wire heating is that it generates heat itself, and the power density ...

The heating coils of ordinary electrical products generally have the disadvantages of uneven heating and inability to perform precise temperature control

The traditional 2D coil heating method will lead to high heat loss. For example, the traditional electric heating pan heats the bottom of the inner pot, and the heat is conducted from the bottom to the upper part through contact conduction. The disadvantages of this are slow heating, uneven heating, and more Not to mention intelligent and precise control of heat, air pressure and moisture

In addition, there is another big disadvantage of resistance wire heating, which is that it needs to generate heat itself, and the power density it can withstand is low, so it cannot adapt to some heating occasions that require higher temperature.

Therefore, the existing coil products can no longer meet people's needs
