Manufacturing method of refrigerator interior trim decorative strip

Abstract

The invention discloses a manufacturing method of a refrigerator interior trim decorative strip. The method comprises the following steps of designing and manufacturing an aluminum mold, carrying outpretreatment inspection and flatness inspection on the surface of the aluminum mold, carrying out high-temperature melting on a plastic raw material, adding activated carbon as an additive, carrying out injection molding, cooling and demolding treatment, coating a nano coating film, and carrying out a deformation test in a cut-off treatment extreme temperature environment. The aluminum mold is adopted for injection molding to manufacture the decoration strip, the utilization rate of the mold can be increased, the molding stability is good, the production efficiency can be effectively improved,activated carbon ultrafine powder is added into the plastic raw material, the decoration effect is achieved, meanwhile, the problem that peculiar smells in the refrigerator are large can be solved, and by coating the surface of the decorative strip with the nano coating film, the problem that the decorative strip easily adsorbs oil stains and is difficult to clean can be effectively solved.

Description

technical field [0001] The invention relates to the field of refrigerator manufacturing, in particular to a method for manufacturing a refrigerator interior trim strip. Background technique [0002] At present, with the continuous development of my country's economy and society, the production capacity of household appliances is also increasing year by year. Refrigerators are one of the necessary household appliances, and their market demand is increasing. The production of refrigerators includes the manufacture of parts and the assembly of various parts. Refrigerator interior decoration strips have also become an important part of the refrigerator production process. [0003] The quality of the decorative strip produced by the existing decorative strip production method is not high enough to meet the existing production needs, and the backward production process leads to low production efficiency. In some existing decorative strip production processes, aluminum foil molds ar...

Problems solved by technology

[0003] The quality of the decorative strip produced by the existing decorative strip production method is not high enough to meet the existing production needs, and the backward production process leads to low production efficiency. In some existing decorative strip production processes, aluminum foil molds are used for molding, resulting in Molding stability is relatively poor, therefore, the present invention proposes a method for manufacturing refrigerator interior decoration strips to solve the deficiencies in the prior art
