Non standard precision partes processus est liber controllus et processus aliorum parterum per industrias propter defectum relevant is specificationibus nacionalibus et regulas parametrorum. Multas varietates non standard produktorum sunt, et nunc non est classificatio standardizata. Classificatio generala secundum est.

Metal non-standard components: Customers provide drawings, and manufacturers use equipment to produce corresponding products based on the drawings. Usually, there are many molds, tolerance requirements, and glossiness that are specified by customers, and there is no certain style. Procedentia requirit correspondent quality control from casting to completion, with complex and variable processes, and generally higher costs than standard products.

Non metallic non-standard components: Processing of some non-metallic materials. In recent years, the development of injection molding industries such as plastics, wood and stone, as well as plastic molds, has become increasingly sophisticated. The use of surface design and programming digital control has greatly increased the cost and tolerance levels of non-standard precision processing components.
