Flat Steel Used for Plastic Mould
Flat Steel is an important type of steel materials which have been widely used in many different areas, such as plastic mould. It is one of the most commonly used steel in the sheet and strip material for plastic mould. Flat steel is also known as strip steel, which is a kind of steel produced with a certain thickness and width ratio. It is strip rolled and processed with stainless acid-proof, wear-resistant and heat resistant steel, which is formed out of various hot rolled and cold rolled plate materials.
Flat steel is used in many fields such as plastic moulds, blister packaging, paint cans and Lumber factories. The flat steel used for plastic moulds has certain requirements of its material properties, and so it needs to meet the YB/T094-1997 standard. This standard specifies the technical requirements, test methods, inspection rules, packaging and marking of flat steel used for plastic moulds. It also specifies the steel grade and chemical composition of the material. According to this standard, the copper content of the steel must not exceed 0.35%. The tensile strength of the material should be more than or equal to 600MPa and the yield strength should be more than or equal to 445MPa.
The flat steel used for plastic mould must have strong corrosion resistance due to its frequent contact with corrosive liquids. So it is necessary to pay attention to the surface treatment of the flat steel. The common methods of surface treatment include galvanizing and plating. These treatments can improve the corrosion resistance of the flat steel by reducing the impurities on the surface of the steel and providing a protective layer.
In addition to corrosion resistance, the flat steel used for plastic moulds should also have excellent ductility, impact resistance and bending performance. This is to ensure the steady performance of the plastic mould during injection moulding. These properties can be obtained when the flat steel has good forming and processability. The flat steel used for plastic moulds should also have good machinability to ensure the accuracy and smoothness of the moulds produced by machining process.
In summary, flat steel used for plastic moulds needs to meet the requirements of GB/T094-1997 standard and has certain requirements of material properties. It should have good anti-corrosion, ductility, impact resistance, bending performance and machinability. These properties can ensure the excellent performance of the plastic moulds produced.
