Carbon steel flanges are designed to have standard dimensions. Common world standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean).
Carbon steel flange faces are also made to standardiz dimensions and are typically "flat face", "raised face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible.
Carbon steel flange designs: Weld neck flange (WN flange), slip-on flange(SO flange), lap joint flange(LJ flange), socket weld flange(SW flange), threaded flange(TH flange), blind flange(BL flange).

Milling, boring, drilling, reaming, tapping and other processes are also used in regular mold processing.
The main material of the mould is high-quality alloy steel. Some moulds with a long service life are often made of Crl2, CrWMn and other ledeburite steels. The production and processing of this material is very strict, so the processing process cannot be ignored. The thermal deformation treatment is also an aspect that needs to be taken seriously in the processing. To sum up, when selecting the airport, the processing conditions should be met as much as possible, such as strong functionality, high accuracy of machine tool, good rigidity, good thermal stability, and anti-type function.
Some surface shapes are composed of multiple curved surfaces, such as automobile cover parts, aircraft, parts, toys, household appliances, etc., so the surface of the mold cavity is very easy to be complicated, and some can be processed through mathematical calculation.
Some molds have neither drawings nor data in the production process, and can only be imitated through physical objects, which requires high imitation accuracy and no deformation.
