What are non-standard precision metal stamping parts
We know that the processing of precision metal stamping parts can be divided into standard parts processing and non-standard parts processing according to the processing objects. It is relatively easy to process standard parts, while the processing of non-standard precision metal stamping parts is relatively difficult. , Many people don’t distinguish between what is a standard part and what is a non-standard precision metal stamping part, so let’s introduce what is called a non-standard precision metal stamping part.
Precision metal stamping parts
Before precision machining of non-standard parts, you must understand what non-standard precision hardware is. First of all, we know that non-standard parts are proposed relative to standard parts, so before we understand non-standard precision metal stamping parts, we must know what is called standard parts . Standard parts refer to the commonly used parts, such as threaded parts, rolling bearings, etc., that have been fully standardized in structure, size, drawing, marking and other aspects and produced by professional factories. The broad sense includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. The narrow sense includes only standardized fasteners. Standard parts commonly known in China are the abbreviations of standard fasteners, which are narrow concepts, but the existence of broad concepts cannot be ruled out. In addition, there are industry standard parts, such as automotive standard parts, mold standard parts, etc., which also belong to broad standard parts.
Precision metal stamping parts
Non-standard parts processing professionals explained that the country has not set strict standard specifications, and there are no other accessories that are freely controlled by enterprises except for relevant parameter regulations. There are many varieties of non-standard parts, and currently there is no standard classification. The general classification is as follows:
Metal non-standard stamping parts
Customers provide drawings, and manufacturers use equipment to produce corresponding products based on drawings. Usually molds are mostly used, tolerance requirements, and finish are all specified by customers, and there is no certain paradigm. Products from casting to finishing require corresponding quality control. The process is complicated 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 and the development of plastic molds have become more and more sophisticated. The surface design and the introduction of programming and numerical control have greatly improved the cost and tolerance level of non-standard processing.
