Compared with standard parts processing, non-standard parts processing is not only non-standard parts processing, but non-standard parts processing mainly refers to other parts that can be freely controlled by enterprises without strict standard specifications and relevant parameter regulations.
The processing of non-standard parts is different from the processing of ordinary parts. This process is usually chosen only when necessary. First of all, we know that non-standard parts are proposed relative to standard parts, so before understanding non-standard parts, we need to know what is meant by standard parts. Standard parts are commonly used parts, such as threaded parts, rolling bearings, etc., which have been standardized in all aspects, such as structure, size, drawing method and marking, and are produced by professional factories. In a broad sense, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. In a narrow sense, only standardized fasteners are included. Domestic commonly known as standard parts is the abbreviation of standard fasteners, is a narrow concept, but can not exclude the existence of a broad concept. In addition there are industry standard parts, such as automotive standard parts, mold standard parts, etc., also belong to the general standard parts.
The processing of standard parts mainly refers to other accessories that can be freely controlled by enterprises except for the absence of strict standard specifications and relevant parameters. There are many varieties of non-standard parts, and there is no very standardized classification yet. They are roughly classified as follows.
Metal non-standard parts.
Customers provide drawings, and manufacturers use equipment to produce the corresponding products according to the drawings. Usually most of the molds, tolerance requirements and finish are specified by customers, and there is no certain paradigm. The products require corresponding quality control from casting to finishing. The process is complex and variable, and the cost is generally higher than that of standard parts.
Non-metallic non-standard parts.
It is the processing of some non-metallic materials. Such as plastic, wood, stone, etc. In recent years, the injection molding industry, the development of plastic molds increasingly sophisticated, surface design, and the introduction of programming CNC, greatly improving the cost and tolerance level of non-injection mold. Standard processing.
