The invention relates to the technical field of filter production and discloses an infusion filter production process. The infusion filter production process comprises the steps that an exhaust film pre-assembly and a filtering film pre-assembly are made on a single-color injection molding machine; after mould closing of a three-color injection molding machine is conducted, an upper cover and a lower cover of a filter are made, after mould opening, the upper cover is retained in an upper cover mould moving mould, and the lower cover is retained in a lower cover mould moving mould; the upper cover mould moving mould and the lower cover mould moving mould are rotated by 180 degrees to enable the upper cover and the lower cover to be arranged oppositely; the exhaust film pre-assembly is placed in the upper cover, and the filtering film pre-assembly is placed in the lower cover; and after mould closing of the three-color injection molding machine is conducted, injection molding is conducted to seal the upper cover and the lower cover into an integrated structure. According to the infusion filter production process, the filter is made into the integrated structure by using the injection molding process, pollution to the filter at the time of manual welding of the upper cover and the lower cover is avoided, the qualification rate of products is increased, the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of filter production, in particular to a production process of an infusion filter. Background technique [0002] Sick people usually need infusion to help speed up treatment and recovery, so infusion set is an indispensable product in modern medicine. During the infusion process, it is often impossible to ensure that the impurities in the liquid are completely removed. At this time, a filter needs to be used to filter the liquid. [0003] In the production of infusion filters in the prior art, the upper and lower covers of the filter are usually produced by a single-color injection molding machine, and then the exhaust film and filter film are manually put into the upper and lower covers, and finally the upper and lower covers are welded by ultrasonic waves. One structure. [0004] There are some defects in the existing filter production process. For example, the process of manually putting the exhaust fil...
