                    Understand the importance of defects in precision castings


   


In actual production, it is often necessary to analyze casting defects, the purpose of which is to find out the cause of the defects so that measures can be taken to prevent them. For precision casting designers, understanding product defects and causes can help to properly design the casting structure and combine the actual conditions of the casting production to properly formulate the technical requirements.
There are many defects in precision castings, and the defects and causes are very complicated. Sometimes, defects caused by many different reasons appear on the same casting, or the same reason may cause various defects when the production conditions are different.
Whether a defective casting with defects is classified as waste must be determined according to the use and requirements of the casting and the location and severity of the defect. Under normal circumstances, there are minor defects that can be used directly; there are medium defects, which can be used after repair; if there are serious defects, they can only be scrapped.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is...
