Punching Process

Punching is a process based on the plastic deformation of metal. It uses molds and punching equipment to apply pressure to the sheet material, causing the internal crystal structure to slip and dislocate, thereby changing the shape of the material. After a separation or forming process, parts with a predetermined shape, size and performance are finally obtained, namely punching parts.

VMT offers a wide range of metal material options, including stainless steel, aluminum alloy, copper alloy, etc., ensuring reliable quality and traceable sources to meet the needs of different industries and applications. We have comprehensive customized services, with professional design teams and technicians to accurately design and produce according to customer drawings or samples.

Our sheet metal punching services cover a wide range of industries, including aerospace, automotive manufacturing, consumer electronics, mechanical equipment, etc., providing targeted solutions. At the same time, we have strict quality control processes and testing standards to fully monitor raw materials, production processes and finished products to ensure that punching products meet customer requirements and industry standards, and improve customer satisfaction and trust.

Punching Type

There are many types of stamping. We provide a variety of stamping methods including four-slide punching, multi-stage punching, progressive punching, deep punching, etc., aiming to ensure that your product is manufactured in the most efficient and suitable way. Stamping types can be divided into the following categories according to their process conditions and finished product characteristics:

1. Classification By Deformation Properties.

Separation process: blanking, which separates the workpiece and the residual material along the predetermined contour through the die to ensure the quality of the section. This process requires precise die design to ensure the flatness and precision of the cut surface.
Forming process: plastic deformation of the blank without damage to form the required shape and size. Including bending, drawing, bulging, etc.

2. Classification By Die Structure.

Simple punching: a single stroke completes a single process, which is suitable for manufacturing parts with simple shapes and small quantities.
Continuous punching: through progressive dies, multiple processes are gradually completed at multiple stations, which is suitable for manufacturing parts with complex shapes and large quantities. Continuous stamping can improve production efficiency and reduce costs.

3. Other Punching Types.

Four-slide punching: Use four sliding tools to shape complex parts through multiple deformations, with low cost and high speed, suitable for manufacturing small complex parts, such as mobile phone battery connectors, etc. Four-slide stamping requires a flexible die design to adapt to parts of various shapes.
Progressive punching: Multiple dies and multiple steps to manufacture deep parts, suitable for large batches and large parts. Progressive stamping can improve production efficiency and reduce costs, but the die design is relatively complex.
Deep stamping: Manufacture deep cavity parts, enhance rigidity, suitable for manufacturing containers, shells, etc. Deep stamping requires the die to have high rigidity and strength to ensure that no deformation occurs during the stamping process.
Hydroforming: High-pressure oil bladders press metal into the die shape, quickly and accurately, and the die needs to be trimmed to cut the part out of the sheet. Hydroforming is suitable for manufacturing large and complex parts.
Embossing: To form a three-dimensional pattern on the metal, either raised on the surface or formed by a series of depressions. Embossing is suitable for making decorative parts, such as signs, panels, etc.

Advantages of CNC Sheet Metal Punching

Improve Production Efficiency.

With its advanced automatic control system, CNC punching machines have significantly improved the speed and accuracy of stamping processing. Its processing capacity is impressive. The stroke rate of general hydraulic equipment can reach 500 to 600 times per minute, and some equipment can reach up to 900 times per minute. This leap in speed directly leads to a significant increase in production efficiency.

Save Mold Costs.

Hole processing of complex shapes and sizes can be achieved through simple molds. This feature greatly reduces the high cost of molds in traditional stamping processes. At the same time, the replacement and debugging process of molds has become more convenient, further reducing production costs.

High Machining Accuracy.

CNC punching machines are famous for their excellent punching accuracy. The workpieces after punching not only have small burrs, but also excellent flatness, which greatly reduces the workload of subsequent processing and effectively reduces the scrap rate. Its processing dimensional accuracy can generally reach 0.1 mm, ensuring the accuracy and consistency of product dimensions and meeting the stringent requirements in the field of high-precision machining.

Strong Adaptability.

The CNC punching machine has a wide range of processing and can cope with the processing needs of holes and contour curves of various shapes and sizes. For sheet metal parts with special processing technology, such as shallow drawing, flanging holes, etc., CNC punching machines also show strong processing capabilities. This highly adaptable feature enables CNC punching machines to flexibly meet the personalized customization needs of different customers

Improve Economic Benefits.

CNC sheet metal punching technology effectively reduces production costs by improving production efficiency and machining accuracy. At the same time, the savings in mold costs and the wide range of machining enable companies to undertake more types of orders, further improving economic benefits.

Tight Tolerances

Whether you are in the aerospace, automotive, telecommunications or electronics fields, our precision metal stamping services can accurately shape your parts. Our team is committed to fine-tuning the output results through repeated iterations of tool and die design to meet your most stringent tolerance requirements. However, the tighter the tolerance requirements, the more difficult the processing and the corresponding cost will also increase.

To ensure that the quality and specifications of each batch of stamped products are consistent, we will conduct strict inspections after each continuous production. At the same time, strict control of tolerances is the key to ensuring product quality and performance. We strive for excellence in every link of design, die manufacturing, equipment technology, process monitoring and quality management system. In the design stage, we need to set precise tolerance ranges and plan reasonable process flows based on the functional requirements and assembly requirements of the product.

In production, we use advanced CNC stamping equipment, combined with high-precision positioning systems, pressure control systems and sensors, to monitor various parameters in the stamping process in real time and optimize the stamping process, such as adjusting the stamping speed, pressure distribution and lubrication conditions to minimize tolerance deviations.
