Introduction of CNC machined valve disc：
The steel precision casting butterfly valve disc is a quarter-turn rotary motion valve used to stop, regulate and start fluids. When the valve is fully closed, the steel precision casting butterfly valve disc completely blocks the line; when the valve is fully open, the steel precision casting butterfly valve disc is at right angles to the media flow direction, allowing smooth flow. CNC machined valve disc is a high-performance fluid control device widely used in agriculture, engineering, automotive industry and other fields. CNC machined valve disc is manufactured by precision casting process, and materials such as stainless steel, carbon steel or alloy steel are selected. CNC machined valve disc has excellent corrosion resistance, strength and durability, and is suitable for various complex working conditions and fluid media. We are equipped with multiple CNC machining centers and CNC lathes, which can achieve high-precision tolerance control of 0.01-0.02mm. We can customize production according to customers' drawings, samples or special requirements, and comply with ISO9001 (2008) quality management system certification.
Processing and manufacturing process of CNC machined valve disc：
1. Casting mold making: Use aluminum mold to make molds that match CNC machined valve disc.
2. Wax mold injection molding: Inject molten wax into metal mold, cool and mold it and then take it out.
3. Wax mold assembly: Fix multiple wax molds on wax tree for mass production.
4. Ceramic shell preparation: Multi-layer refractory coating wraps wax mold to form a solid shell.
5. Dewaxing treatment: Heat to make wax liquid flow out, leaving a precision casting.
6. High temperature roasting: Roasting at above 900°C to improve the strength and stability of the shell.
7. Molten metal pouring: Pour stainless steel liquid into the mold at high temperature, and form butterfly valve disc after cooling.
8. CNC finishing: Use CNC machine tools for fine processing to ensure 0.01-0.02mm tolerance, improve sealing and fluid control performance.
9.Quality testing: 100% physical and chemical testing is carried out to ensure that the quality of CNC machined valve disc meets ISO9001 (2008) standards.
Application industries of cast stainless steel valve disc:
1. Agricultural machinery: irrigation system, fluid control of agricultural equipment.
