Pull ring-Brass precision casting
Product description
This is an electrical accessory, the name is pull ring.
Silicon Bronze is a kind of copper with good mechanical properties, corrosion resistance, processing performance, so it is widely used in the machinery manufacturing industry, shipbuilding industry, power industry, construction industry.
Copper precision casting process difficulties:
Melting temperature control: the melting point of copper is high, need to strictly control the melting temperature, to avoid overheating or overcooling resulting in a decline in material properties.
Liquid metal fluidity: copper in the liquid state of the liquid state of the fluidity is better, but also easy to lead to uneven flow of liquid metal in the mould, the need to ensure that the material is fully filled with details of the mould through the design of a reasonable pouring system and pressure to ensure that the details of the mould.
Oxidation problem: Copper is susceptible to oxidation, it is necessary to reduce the impact of oxidation on the quality of castings through a reasonable design of the pouring system as well as the control of the pouring temperature and pouring speed.
Development history
The product in the trial sample stage, from time to time casting cracks, resulting in a low pass rate; our technical team through many rounds of trial sample verification, and finally solved the problem, and finally meet the conditions of mass production.
This product is a mature product of our company, and has been in stable batch supply since mass production started in 2017;
Our company has a strong technical development team, with the ability to develop a variety of shaped parts in the field of precision casting, striving for excellence, to provide customers with efficient, high-quality products and services has always been our adhering to the concept.
