Weight: 1.2 KG
Process: coated sand casting process, precision machining, dimensional inspection report, pressure test, shot blasting, surface painting.
Process analysis: The product is a valve type accessories, such accessories will have pressure requirements, so the pressure test will be carried out after the production of the product to ensure that the product does not leak. The product is made of GGG60 material and adopts the coated sand shell casting process for blank production. The advantage of the coated sand process is that the casting size of the product can reach CT8 grade, which is the highest grade that can be achieved by the sand casting process. The appearance of the product is relatively delicate, and the strength of the shell is larger because the shell is pressed. It is the best choice for pump valve products. After the blank is made, the precision machining process will be carried out, and the special tooling is specially made for clamping, the accuracy can reach 0.01mm. Issue quality inspection report, material inspection list and pressure test report after processing. Finally, spray paint treatment, packaging and delivery.
