316 precision casting valve rough embryo, processing and assembly process is as follows:
Casting process flow: According to the parts drawing to be produced, production batch and delivery deadline, formulate the production process plan and process documents, and draw the casting process drawing.
Production preparation: Prepare materials for melting, materials and patterns for molding and core making, core boxes, sand boxes and other process equipment.
Molding and core making: Position the pattern on the molding machine and tighten it, then fill it with sand, tighten it, remove the mold, trim it, and make the core.
Melting and pouring: The metal is heated and melted to make it fluid, and then poured into a casting cavity with a certain shape. It fills the cavity under the action of gravity or external force, cools and solidifies into a casting.
Falling sand cleaning and casting inspection: Separate the castings from the sand box, clean the sand box and casting surfaces, and inspect the surface size, shape, roughness, etc. of the castings.
Mechanical processing: Mechanical processing of castings, such as turning, milling, drilling, etc.
Assembly: Assemble the processed parts to form a complete valve.
Test: Conduct pressure, flow and other tests on the assembled valve to check the performance and quality of the valve.
Painting and packaging: Paint and package qualified valves to protect them from corrosion and damage.
What are the raw materials used for welding the pump head? How to choose raw materials?
The raw materials for welding and processing of pump heads are usually metal materials, such as stainless steel, copper, aluminum, iron, etc.
Material: Different metal materials require different welding processes and equipment, so it is necessary to choose the appropriate material based on the working environment and requirements of the pump head.
Strength: The pump head needs to withstand certain pressure and impact loads, so it is necessary to choose raw materials with sufficient strength.
Corrosion resistance: If the pump head is in a corrosive environment, it is necessary to choose raw materials with anti-corrosion properties.
Cost: Welding and processing of pump heads requires a certain amount of cost, so it is necessary to choose low-cost raw materials as much as possible while ensuring quality.
Quality: The pump head is a key component that needs to ensure stable quality, so it is necessary to choose high-quality and reliable raw materials.
