Detailed Description
sleeves very few materials of machining (such as: chamfering, drilling, car or pressure oil) can be installed directly use the collar parts products.
Our factory adopts "the sintering process law" set rolling double metal parts materials, the characteristics of sleeves (1) for the whole circle, structure and good stiffness, maintain good accuracy and relative density, convenient in assembling automatic production line automation, (2), high production efficiency (complete a collar average more than 4 seconds), processing procedure, saves the use of traditional sintering dual metal plate, the cutting material must take the mould and rolled and process equipment, equipment use less, only two sets of main equipment, cover an area of an area small, Contrast (see table), (3), high efficiency, material according to the requirements of the size, steel and copper alloy utilization close to 100%, energy-saving, materialsaving, reduce the production cost. (4), use this dual metal sleeves part, just a fractal materials (such as: the mechanical chamfering, drilling, car or pressure oil) can use directly into the collar is installed.
Use it instead of GB / 18324-2001 copper alloy in overall collar diameter of 100 ~ 220 or larger size of energy saving, materials, especially, more profound social economic benefit.
At present, pipe diameter less than 30mm diameter 80mm 80mm length less than the product we can offer
