Manufacturing method of plastic composite shell of medical electronic product

Abstract

The invention discloses a manufacturing method for a plastic composite shell of a medical electronic product. The manufacturing method comprises the following steps that 1, an inner core flow guide frame I is prepared according to the shape of a finished product shell to be prepared; 2, a reinforcing agent, an antioxidant, a flame retardant and an antibacterial agent are added into plastic raw materials, and then heating and stirring are conducted to obtain molten plastic I; 3, a foaming agent is added into the molten plastic I, and molten plastic II is obtained after stirring and standing; 4, the inner core flow guide frame I is placed in a mold forming cavity, then mold closing is conducted, the molten plastic II is injected into the forming cavity, and an injection molding part I is obtained; 5, gas in the inner core flow guide frame I is replaced with sterilization gas through a gas injection needle, pressure maintaining treatment is conducted, and a plastic part II is obtained; and 6, a re-drying process is conducted, specifically, the plastic part II is placed in a drying oven to be subjected to high-temperature re-drying. The invention relates to the manufacturing method capable of endowing the plastic composite shell with high strength and self-sterilization capability.

Description

technical field [0001] The invention mainly relates to the technical field of preparing electronic product casings, in particular to a method for manufacturing plastic composite casings of medical electronic products. Background technique [0002] The outermost layer of electronic products is often a plastic composite casing. The main function of the plastic composite casing is to protect and support the internal electronic components, and it can also play a decorative role. The plastic composite casing of medical electronic products has many bacteria in the use environment. With automatic sterilization function. [0003] According to a molding method for an electronic product casing provided by the patent document with the application number CN201310452879.9, the molding method includes the following steps: placing a composite material composition including fibers and thermoplastics in a cavity of a mold, and placing the mold The temperature is raised rapidly to fuse the t...
