Problems solved by technology
The production process of the existing induction cooker cover is simple, and its instructions or patterns are directly printed on the surface of the induction cooker cover. After a long time of use, the instructions or patterns will appear blurred, which will bring trouble to the operation; I usually like to use the wok with the induction cooker. However, in the process of frying or frying food, the temperature is high, and the oil is prone to splash on the surface of the induction cooker, which will damage the cover of the induction cooker.

Embodiment
[0027] Example: see figure 1 , the present embodiment provides a product shell treatment process, which includes the following steps:
[0028] (1) Molding: Take out the injection-molded product surface from the injection molding machine, remove the nozzle, apply a protective film on the window of the product surface, and then place it;
[0029] (2) Film: Tear off the protective film on the surface of the product, and then blow and wash the surface of the product with an electrostatic gun for electrostatic dust removal; paste protective tape on the front of the window part of the product surface, and paste protection on the back of the window stickers, and then neatly placed on the shelf;
[0030] (3) Stress release: place the product surface shell that has completed the film pasting process in a baking oven to bake to remove stress; preferably, the baking temperature in the step (3) is 78-82°C, and the time is 10-30 minutes .
[0031] (4) Spraying the primer: Spray the prim...

The invention discloses a product shell processing technique which includes the following steps of (1) forming, (2) film pasting, (3) stress releasing, (4) primer spraying, (5) laser carving, (6) grinding, (7) screen printing, (8) finishing coat spraying, (9) back surface polishing, (10) front surface polishing and (11) packaging. The technique provided by the invention is easy and convenient to operate and easy to achieve; primer and finishing coat are matched, the primer is used for displaying the required color effect, and the finishing coat is used for improving abrasion resistance and high-temperature resistance of a shell; the problems that after long-time use, indications or patterns become blurry, and in the food frying process, high-temperature oil splashes and consequently the shell is damaged are effectively solved, the service life is effectively prolonged, and the product appearance attractiveness is improved; and the spraying technique is simple, cost is low, production is facilitated, and large-scale application and popularization are facilitated.
Description
technical field [0001] The invention belongs to the technical field of product surface shell treatment, and in particular relates to a product surface shell treatment process applied to electrical appliances. Background technique [0002] Induction cooker is also known as induction cooker. In 1957, the first household induction cooker was born in Germany. In 1972, the United States began to produce induction cookers, and in the early 1980s, induction cookers began to sell well in Europe, America and Japan. The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the alternating current is used to pass through the coil to generate an alternating magnetic field with a constantly changing direction. Eddy currents will appear inside the conductor in the alternating magnetic field, which is the eddy electric field that drives the current-carrying in the conductor. The Joule heating effect of the eddy current heats up the conductor, thereby a...
