Embodiment Construction

[0018] This embodiment takes the processing method of the rear plate of the refrigerator as an example.

[0019] A method for processing the rear panel of a refrigerator / freezer, using tough plastic materials such as PP, HDPE, ABS, HIPS, PVC, etc., and using a special surface treatment and molding method to prepare a new panel that meets the requirements of the refrigerator / freezer profiles.

[0020] The simple processing route of the side panel, rear panel and rear bottom panel of the refrigerator / freezer is: plastic pellets→extruded into plates, sheets and surface treatment→cutting→secondary processing and forming (including die stamping and bending forming)→ The surface is corona treated.

[0021] Select strong and tough plastic pellets, such as PP, HDPE, ABS, HIPS, PVC and other plastic pellets, to process the above plastic pellets. The specific steps are as follows:

[0022] (1) Extrude plastic pellets into plates, sheets and surface treatment, but usually for side pane...

Abstract

The invention discloses fridge / refrigerator side, back, and base boards processing method. It includes the following steps: extruding plastic grain into plastic plate and sheet material; cutting; processing secondary operation forming; processing surface physical treatment. The invention has the advantages of good forming effect and surface physical property.

Description

technical field [0001] The invention relates to the technical field of refrigerators / freezers, in particular to a method for processing side panels, rear panels and rear bottom panels of refrigerators / freezers. Background technique [0002] At present, most of the side panels, rear panels, and rear bottom panels used in refrigerators / freezers are metal sheets, which include metal sprayed sheets, galvanized sheets, galvanized sheets, etc. It is cardboard or hollow board, also known as calcium plastic board or corrugated board. Among them, the metal plate has high strength and is easy to form, but it is expensive and easy to rust; although cardboard and hollow board are cheap, it is difficult to shape, and the strength is low, and the appearance of the product is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for processing side panels, rear panels and rear bottom panels of ...
