For precision Sheet Metal Parts, the processing is very strict. The processing procedures include feeding and discharging.  There are specific requirements for size and precision, such as how many microns plus or minus 1mm, etc. If there are too many wrong sizes, they will become waste products. At this time, it is equivalent to reprocessing, which takes time and effort, and sometimes even makes the whole processing material scrap, thus causing an increase in cost. At the same time, parts are definitely unusable.
For precision metal plate parts processing is mainly the size requirements, such as the cylinder diameter is how many, there are strict requirements, positive and negative errors within the prescribed requirements are qualified parts, otherwise are unqualified parts;  There are also specific and strict requirements for length, width and height. Positive and negative errors are also specified. For example, if the diameter of an embedded cylinder (take the simplest basic metal plate part as an example) is too large and exceeds the allowable error range, it will lead to the situation that it cannot be inserted. If the actual diameter is too small and exceeds the lower limit of the allowable negative error value, it will lead to the problem that the insertion is too loose and unstable.  These are all unqualified products, or the length of the cylinder is too long or too short, which is beyond the allowable error range. They are all unqualified products and must be discarded or reprocessed, which will inevitably lead to an increase in costs.
The above is the requirement for precision metal plate parts processing. It is the most important dimension problem. It must be processed strictly in accordance with the additional drawing. The actual dimension processed will definitely not be exactly the same as the theoretical dimension of the drawing. However, as long as the processing dimension is within the tolerance range, it is qualified metal plate parts. Therefore, the requirement for precision metal plate parts processing is to process strictly in accordance with the theoretical dimension.
The second is the advanced precision Bakelite Parts processing equipment and testing equipment. The advanced processing equipment makes the processing of precision parts simpler, more accurate and more effective.  Testing equipment can detect phenolic plastic parts that do not meet the requirements, so that all products sent to customers can really meet the requirements.
