    There are castings, forgings, profiles and weldments commonly used in machining Different kinds of blanks and the accuracy, roughness and hardness of the blanks have a direct impact on the machining process When selecting the valve blank, the following factors should be considered: (1) the material of the parts and the requirements for the structure and performance of the materials The part materials specified in the design drawings largely determine the types of blanks For example, if the part material is cast iron, the casting method must be used to make the blank For steel parts, the mechanical properties of the material should be considered when selecting the blank For example, forging or welding parts shall be generally selected for manufacturing high-pressure valve parts to ensure good mechanical properties of materials The structure shape and dimension of the parts of humidity sensor probe, stainless steel electric heating pipe PT100 sensor, cast aluminum heater, heating ring fluid solenoid valve (2) The structure switch of parts is an important factor that affects the selection of blanks For example, the valve body with complex structure switch can be cast The valve body with large size can be sand casting; the valve body with small size can be investment casting (3) the size of production program The larger the production program of parts, the better the economic effect of adopting the high precision and rate of blank manufacturing method (4) conditions for rough manufacturing It is necessary to select the blank according to the equipment and process level on site, and gradually adopt the advanced blank manufacturing method considering the development prospect.
