Kaifeng Shire Import and Export Co., LTD is a dynamic and innovative foreign trade company that was established in 1984 and specialises in the import and export of industrial parts. The company is mainly involved in two types of products, namely stamping parts/metal stamping and die casting/pressure casting. Stamping parts/metal stamping process uses a metal mold to apply pressure to a sheet of metal, causing it to deform plastically into a part of the desired shape. Stamped parts are characterised by thinness, uniformity, lightness and strength. It is suitable for high precision, high volume production, but often involves complex manufacturing processes and long lead times.
Materials commonly used for stamping include cold-rolled sheet, galvanized sheet/galvanized plate, stainless steel, copper aluminium alloy. These materials are subjected to tensile, compressive and bending forces during the stamping process to change shape and size. The advantages of stamped parts are that they are highly efficient, accurate, cost-effective, suitable for mass production, and capable of producing complex and sharply contoured parts. However, stamping also has disadvantages, it requires high precision of molds, complex manufacturing process, high cost and long production cycle, while stamping has limited applicability to small-scale production and it is difficult to meet the high precision requirements of individual parts.
Surface treatment refers to the process of modifying the surface of a material to improve its properties. such as hardness, corrosion resistance, wear resistance, or appearance. This is particularly important in the hardware industry, where products such as locks, hinges, bolts, and machinery parts are exposed to environmental factors that can cause degradation over time.
There are various methods of surface treatment for stamped parts:
For examples: galvanize/zinc plating: galvanize/zinc plating as a surface treatment technique to cover the surface of a metal, alloy, or other material with a layer of zinc, is designed to enhance the material’s aesthetics and rust resistance. It is characterized by its low cost, moderate corrosion resistance, and silvery-white appearance.
Copper plating/copperize: copper plating/copperize is the process of forming a copper covering layer on a metallic or non-metallic surface by electrochemical deposition or other methods.
Nickel plating/nickelage: the method of plating a layer of nickel on a metal or some non-metal by electrolytic or chemical means is called nickel plating.
Chrome plating/chromeplate: the chrome plating/chromeplate process is designed to enhance the hardness and aesthetics of metal surfaces while providing excellent rust protection. Chrome plating/chromeplate is resistant to alkalis, sulfides, nitric acid and most organic acids.
Electrophoresis/cataphoresis: electrophoresis/cataphoresis is a surface treatment process that provides good corrosion protection for metals by forming a uniform and strongly adherent coating on the surface of the workpiece.
Spray painting/sand blast: spray painting/sand blast refers to the use of high-speed airflow driven sand particles impact on the surface of the workpiece, cleaning stains, increase roughness, beautify the surface, improve coating adhesion.
Kaifeng Shire Import and Export Co., LTD produces stamping parts for a wide range of applications, for instance, home appliance industry, automobile industry, machinery manufacturing, building hardware and daily necessities.What’s more, our company will use neutral salt spray test to extend the service life of stamped parts.
Kaifeng Shire Import and Export Co., LTD evaluates the corrosion resistance of materials and coatings by accelerating simulated salt spray environments, mainly for 24H, 48H, 72H, 96H, 120H, and 240H. We have a wide range of drawing formats such as PDF, CAD and 3D (stp, lgs, dfx), we also accept the customization of size, you can send us the design according to your requirements, we will do our best to meet your needs with quality service.
Kaifeng Shire Import and Export Co., LTD will control the quality strictly. Firstly, material inspection–Check the material surface and roughly dimension. Secondly, production first inspection–To ensure the critical dimension in mass production. Thirdly, sampling inspection–Check the quality before sending to the warehouse. Most importantly, pre-shipment inspection–100% inspected by QC assistants before shipment.
