How to choose a professional bronze casting manufacturer?

Do you need bronze casting parts which have high fatigue resistance and good corrosion resistance? Hiring a casting manufacturer who can provide you with high-quality bronze casting engineering products can be your best choice. Wondering how to choose a reliable casting manufacturer? Read on.

Below are the essential factors you must consider when choosing reputed bronze casting manufacturers.

According to the processing price of copper, it generally depends on the bronze material used and the specific processing technology.

Secondly, the labor price in different regions will also be affected. bronze bushing, also referred to as copper bushing, is an accessory made of bronze through casting. It is used in machine operations. It can reduce friction, vibration, corrosion, noise, and easy maintenance. Simplify the structure manufacturing process. At present, the bronze sleeve is widely used in machine parts. However, when the machine is running for a long time, the bronze sleeve will also have a certain amount of wear, and it will also have a life span. If its wear program reaches a certain level, it will affect the machine. During normal operation, it must be replaced in time. At the same time, because the cost of casting bronze kits is relatively cheap, it is currently widely used in the machinery manufacturing industry.

Inspection standards:

1. Appearance quality The surface of the sample should be free of bubbles, burrs, deformation, uniform material, and no irritating odor.

2, size

(1) The relevant dimensions for testing with vernier calipers shall meet the requirements of relevant technologies and drawings.

(2) After the shaft sleeve is matched with the rotating shaft, the rotor is vertically downward, and the shaft sleeve will not slide freely under its own weight.

3, heat resistance, aging resistance test

(1) After the sample is subjected to 125℃/1h ball pressure test, the indentation should be ≤2mm, and there is no deformation by visual inspection.

(2) After putting the sample in the oven at 120°C/96 hours, visually check that there is no embrittlement or deformation of the shaft sleeve.

4, flame resistance test

The flame retardant grade is VW-1, and it should be extinguished within 15S after burning with alcohol lamp for 15S.
