Custom Metal Stamping Dies

The production of Custom Metal Stamping Dies is a common industrial processing method used to process materials into specific shapes. It is a very common process in the production of mass products. The application scenarios of mold processing are very extensive, ranging from automotive parts, aerospace to hardware accessories. Therefore, molds are also known as the "mother of Industry". In China, Xiamen Hongyu Intelligent Technology Co., LTD., as one of the leading metal stamping enterprises, has strict quality control. Through raw material inspection, process inspection and final inspection, we are willing to present the best products to our customers.

Determine the process plan

Formulating the Metal Stamping Dies process plan is an important part. Process analysis includes process analysis based on the shape characteristics, dimensional accuracy and surface quality requirements of the workpiece. First of all, it is necessary to confirm and list all the basic processes to be used, such as blanking, punching, bending, stretching, flanging and bulging.

Based on process calculations and the requirements for shape and dimensional accuracy, the number of processes is determined, such as the number of stretching times for stretched parts and the number of processing times for bent parts, etc.

The processing sequence is determined based on the deformation characteristics of the processing, dimensional accuracy requirements and operational convenience. For instance, if a product requires both stamping and bending processing methods, should it be stamped first and then bent, or bent first and then stamped?

Based on various factors such as production batch, size, precision requirements, progressive die stamping manufacturing level, and equipment production capacity, such as compound stamping process, continuous stamping process, etc., generally speaking, large-batch, low-precision requirements, thick materials, and large-sized products are suitable for single-process production. High-precision products are suitable for compound die stamping.

Forming properties

Metal or non-metal materials are placed in Metal Stamping Dies, and pressure is applied by the stamping machine to deform the materials, thereby obtaining the required parts. This is the stamping process. Stamping technology is widely applied and can process metal sheets, bars and non-metallic materials. Stamping processing is mainly carried out at room temperature.

The manufacturing of molds not only requires high processing accuracy but also good surface quality of the processed parts. The manufacturing tolerance of the working part of a common mold needs to be controlled within ±0.01mm, and for some high-precision parts, it even needs to be controlled at the micrometer level. Meanwhile, the surface roughness of the working part must also be less than 0.4μm. The precision of the mold determines the precision of the product, and the roughness of the mold determines the roughness of the product. The working part of a metal stamping die is usually a complex curved surface composed of two or three dimensions, which has high requirements for material hardness. It is usually made of materials such as quenched tool steel to meet the high-intensity working requirements of repeated stamping processing of molds.

The various performance requirements of stamping processes are not absolute, especially in the context of the rapid development of stamping technology at present. We need to select a reasonable processing method based on the actual production demands and possibilities, correctly formulate the stamping process flow and choose an appropriate die structure, which should not only meet the technical requirements but also the conditions of the stamping process.

Design

The design of Metal Stamping Dies is a systematic and comprehensive process, involving material deformation, mechanical calculation and precision machining. For instance, a stamping die is a die used for cutting, blanking or punching. Most of them are used in fields such as gasket cutting and hardware parts cutting. As the cutting surface of the mold needs to be repeatedly stamped, it is necessary to consider heat treatment of the cutting edge, such as processing it to HRC58-62 degrees or titanium plating. This can extend the service life of the mold and reduce the impact of excessive burrs caused by mold wear on the cutting of accessories.
