Problems solved by technology
[0002] The outlet pipe is used as a water supply pipe. When it is used as a pipe for direct drinking water, for the sake of water safety and sanitation, it is necessary to use metal or plastic that will not add pollutants (such as NSF standard materials) to the water. Among them, if it is made of metal that meets the standards, there is a problem of high cost, and if it is made of plastic, there are problems of low aesthetics and poor texture

Abstract
Provided are a water outlet pipe, a faucet and a method for manufacturing the water outlet pipe. The method for manufacturing the water outlet pipe comprises the following steps: preparing an outer pipe shell (10) made of metals; preparing an injection mold comprising a mold core assembly and a mold plate assembly having a closed mold state and an open mold state; when the mold plate assembly is in the open mold state, placing the outer pipe shell (10) in the mold plate assembly, and carrying out a mold closing treatment on the mold plate assembly; in the mold closing process, placing the mold core assembly in a pipe of the outer pipe shell (10) until the mold plate assembly is in the closed mold state, wherein at this moment, the mold core assembly and the outer pipe shell (10) together form a tubular mold cavity; injecting a molten-state plastic into the mold cavity; and carrying out a cooling solidification treatment on the molten-state plastic in the mold cavity. The lead content of the water flowing out from the water outlet pipe is 0.
Description
technical field [0001] The invention belongs to the technical field of water pipe manufacturing technology, and in particular relates to a water outlet pipe, a faucet and a method for manufacturing the water outlet pipe. Background technique [0002] The outlet pipe is used as a water supply pipe. When it is used as a pipe for direct drinking water, for the sake of water safety and sanitation, it must be made of metal or plastic that will not add pollutants (such as NSF standard materials) to the water. Among them, if it is made of metal that meets the standards, there is a problem of high cost, and if it is made of plastic, there are problems of low aesthetics and poor texture. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a method for manufacturing an outlet pipe, which aims to improve the texture and aesthetics of the outlet pipe, reduce manufacturing costs, and make t...
