Product details
Repair and refurbishment of old barrel screws:
With the continuous increase in the content of engineering plastic glass fiber, as well as the addition of various fillers, modifiers, etc., the production of plastics such as electric wood and iron powder is prone to wear and tear on the machine barrels and screws of plastic machinery. The frequency of replacing parts has also increased, correspondingly increasing the production costs of enterprises.
Processing technology:
Our company has an advanced set of equipment and mature technology for repairing machine barrels and screws. After renovation, the concentricity and clearance of the machine barrel and screw, as well as the smoothness and glossiness of the inner hole of the machine barrel and the outer diameter of the screw, are almost the same as those of the new machine barrel and screw, and are more wear-resistant.
The inner hole of the barrel is reamed, ground smooth, and then subjected to nitrogen treatment, or due to the significant wear of the old barrel's inner hole, alloy is used to make the inner hole meet the tolerance requirements;
Use imported wear-resistant alloy steel to weld the screw edges, and use nickel alloy high-temperature spraying, nitriding, precision grinding and other processes on the surface to grind smooth and match the inner hole of the barrel, so that the old barrel screw can achieve the same effect as the new product.
