Matters needing attention in the production of Pressed ventilation elbow products

Pressed ventilation elbow products are a kind of pipe fittings. The purpose of Pressed ventilation elbow products is to connect pipes into pipeline parts. According to the connection method, it can be divided into four categories: socket pipe fittings, threaded pipe fittings, Pressed ventilation elbow products pipe fittings and welded pipe fittings.

The commonly used specifications and models of Pressed ventilation elbow products have been replaced by hot push Pressed ventilation elbow products, but in some specifications and models, the number of Pressed ventilation elbow products produced is relatively small, and the wall thickness is too thin or too thick.

Pressed ventilation elbow products

Pressed ventilation elbow products have special requirements to use the stamping manufacturing process. During the molding process of stamping Pressed ventilation elbow products, the diameter needs to be the same as that of the produced Pressed ventilation elbow products, and a press is used to directly press and shape in the mold.

Pressed ventilation elbow products are divided into cold stamping and hot stamping. The material selection and manufacturing process of the stamping elbow is more. The manufacturing process of the elbow is not as good as that of the push elbow, and the quality and appearance are not as good as the former. The outer arc of the stamping elbow is stretched when it is formed. state, there is no excess metal in other parts to compensate, so the wall thickness at the outer arc is about 10% thinner.
