Such smooth working condition only after pu castor, ( ) Casting production is the metal melting, heating the liquid, and then poured into the mold cavity of to have a certain shape, in the external force or gravity ( Pressure, centrifugal force, electromagnetic force, etc. ) Under the action of cavity, cooling and solidification in caster casting ( Or parts) A method of metal forming. Pouring out if there is defect inspection must be separate the defective products, and inform the related department to analysis the reasons of the defects, and corrected in the next production at temperature below 5 & deg; And more than 30 C & deg; C under the conditions of use, the effect of castor will decline, especially in the use of temperature below or above the above data, has been listed in the normal load may be affected. Can repair defects were analysis, such as repair welding, etc. Not all products are need to do heat treatment, basically see your product materials, product use in what aspects. Do heat treatment was to eliminate internal stress or increase or decrease the hardness of products, in order to facilitate processing. Some is also the guests have special requirements, all of these are according to the specific situation to analysis. Caster casting can not restricted by metal material, size, and weight. Caster casting material can be all kinds of cast iron, cast steel, aluminum alloy, copper alloy, magnesium alloy, titanium alloy, zinc alloy and all kinds of special alloy materials; Caster casting can be as small as a few grams, big to hundreds of tons; 5 mm to 1 m; Caster casting length can range from a few millimeters to more than ten meters.
