Water Glass Investment Casting Exhaust Pipe

Material: 35# steel
Quantity: 3500 pieces/batch
Weight: 0.8KG
Process: water glass investment casting, tempering treatment, milling machine processing, drilling processing, surface shot blasting, spray painting.
Process analysis: The product is exhaust pipe accessories in agricultural machinery. According to the production requirements, casting accuracy and dimensional tolerance of the drawing, we choose water glass investment casting process to produce blanks. In the shape and internal size can meet the requirements of the drawing.
After the casting is completed, the tempering treatment is carried out to improve the mechanical properties of the product. After tempering, it is necessary to process the contact surface and cooperate with the processing tools to complete the processing and production. After quenching and tempering, shot blasting and sandblasting are carried out before processing, so only burr removal and spray painting can be carried out after processing.
