The checking fixtur is a simple tool used by industrial production enterprises to control various sizes of products (such as aperture, space size, etc.) to improve production efficiency and control quality. It is suitable for mass production of products, such as auto parts, to replace professional measuring tools, such as smooth plug gauge, spiral plug gauge, outer diameter caliper gauge, etc.
Moulds are various molds and tools used in industrial production to obtain required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, a mold is a tool used to shape objects. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of article shape by changing the physical state of the formed materials. It is known as the “Mother of Industry”.
Therefore, the mold and the checking fixturel are not the same thing. In the design direction, they are similar. The design direction of the checking fixturel is slightly wider. Mold design generally refers to plastic mold and sheet metal stamping mold, which are divided according to different basic materials; The checking fixturel is the equipment to check whether the product conforms to the design data. Whether plastic parts or sheet metal parts need to be clamped on the checking fixturel to check whether the key geometric tolerance conforms to the design requirements. The theoretical basis for designing checking fixturels is GD&T and RPS, which can take plastic and sheet metal together and be flexible; But it is also a good choice if you are specialized in a certain category.
