Manufacturing method of faux-metallic plastic valve

Abstract

The invention discloses a manufacturing method of a faux-metallic plastic valve. The manufacturing method comprises the steps of conducting injection molding on a green body; cleaning the green body;plating a metal film on the outer surface of the green body. The faux-metallic plastic valve has a good metal feel. A ceramic layer is plated on the inner surface of the faux-metallic plastic valve. The safety performance of the valve can be further improved.

Description

technical field [0001] The invention relates to the field of manufacturing valves, in particular to a method for manufacturing plastic valves imitating metal. Background technique [0002] Valves are generally composed of a valve body and valve internals inside the valve body. According to the manufacturing materials, they can be divided into metal valves, plastic valves and ceramic valves. [0003] In terms of production technology and process, metal valves are more mature among domestic valves. Stainless steel valves and copper valves are more common in the market. There are also cast iron valves in slightly lower-end products, but there are quite a lot of defects in existing metal valves. , Metal valves are extremely prone to corrosion, rust, and plating peeling during long-term use. Heavy metals such as lead and tin in alloys used to manufacture metal valves will gradually penetrate into domestic water, causing pollution to domestic water. directly affect people's healt...

Problems solved by technology

[0003] In terms of production technology and process, metal valves are more mature among domestic valves. Stainless steel valves and copper valves are more common in the market. There are also cast iron valves in slightly lower-end products, but there are quite a lot of defects in existing metal valves. , Metal valves are extremely prone to corrosion, rust, and plating peeling during long-term use. Heavy metals such as lead and tin in alloys used to manufacture metal valves will gradually penetrate into domestic water, causing pollution to domestic water. directly affect people's health

Although plastic valves have high safety, their texture is poor.
