ShengPeng is a benchmark in the metal processing industry for quality and precision. Over the past 18 years, we have been dedicated to mastering the technology of metal stamping and have steadfastly provided reliable services to customers all over the world. As an experienced Chinese manufacturer, we combine the most advanced technology with profound professional knowledge to offer custom stamped parts with the strictest specifications.
Metal stamping is a widely used manufacturing process that employs cold forming technology. It uses a press machine and custom-designed molds to transform thin metal sheets into specific, often complex shapes. This process is highly efficient, offers excellent precision and cost-effectiveness, and is suitable for medium to high-volume production lines.
It encompasses various techniques, such as punching, piercing, bending, and deep drawing, and can produce a wide range of products, from simple brackets to complex electronic components. At Shen Peng, we utilize this process to manufacture durable, reliable, and parts with high precision requirements for industries such as automotive, aerospace, electronics, and home appliances.
Transition Summary: Now that we've outlined the fundamentals of metal stamping, let's explore the critical first step in any successful project: collaborative design and engineering. This phase ensures the final part is not only functional but also optimized for manufacturability and cost.
Customized stamping components all start with rigorous design. Our engineers work closely with customers to review part drawings, three-dimensional models, and performance requirements. We use advanced CAD and Solidworks software to conduct virtual modeling of the parts and their stamping processes.
This stage is crucial for designing manufacturability analysis, during which we can identify potential production problems, propose material alternatives, and recommend tolerance standards to ensure that the parts can be efficiently produced without compromising their functional performance. This forward-looking collaboration can save time and reduce costs, and can prevent problems before mold manufacturing begins.
The stamping die is the core of the entire production process, determining the shape and characteristics of the stamped parts. To maintain consistency in thousands or even millions of cycles, investing in high-quality dies is essential. At Shenpeng, our die manufacturing personnel use CNC machining, wire cutting electrical discharge machining, and grinding techniques, and use quenched tool steel to create the dies. We have developed various types of dies, including single-stage, composite, and continuous stamping dies, which are specially designed based on the complexity of the parts and the production volume. Our 18 years of experience ensures that our dies are durable, highly precise, and have low maintenance requirements.
Transition Summary: With the precision tooling designed and manufactured, the next step is selecting the perfect raw material. The choice of metal directly influences the part's strength, durability, corrosion resistance, and overall suitability for its intended application.
The performance of stamped parts is related to the material. Shen Peng has extensive experience in processing various metals and can meet different mechanical and environmental requirements. We assist our clients in selecting the most suitable and cost-effective materials based on factors such as required strength, formability, conductivity, and corrosion resistance.
Our internal quality control begins here, where we inspect the grade and condition of each roll or sheet of metal material to ensure it meets the specified standards before entering production.
Table 1: Common Metals Used in Stamping and Their Properties
| Metal Alloy | Key Properties |
|---|---|
| Cold Rolled steel | Good Strength, smooth Surface finish, cost-effective |
| Stainless steel(304,316...) | Excellent corrosion resistance, high strength |
| Aluminum(5052， 6061) | Lightweight, good corrosion resistance, high conductivity |
| Copper & Brass | Excellent eletrical and thermal conductivity, corrosion resistant |

The press machine can provide the huge pressure required for metals. Modern press machines are complex machines that can control with extremely high precision, speed and stroke. Shen Peng's factory is equipped with various mechanical and servo-driven press machines, enabling us to match the machines according to the specific requirements of the work.
Whether it is high-speed production of small electronic parts or performing deep drawing operations that require precise tonnage control, we can do it. The press machine feeds the metal coil or sheet into the mold, and then the mold will complete the necessary operations in a very short time. Each press can produce one finished part.
Different parts have different stamping methods required. Shen Peng excels in various technologies. Progressive stamping is very efficient for mass production projects. Metal sheets pass through multiple stations in a mold, with each station performing different operations until the final component is ejected. Transfer stamping is suitable for larger parts. It uses separate molds and mechanical transfer systems to move the parts between stamping machines. Deep drawing is a method specifically used for manufacturing seamless, hollow components. It is achieved by pulling the metal blank into the mold cavity and using a punch to compress it.
Transition Summary: After the part is stamped, it is rarely considered complete. Most components require various secondary operations to achieve their final specifications, enhance functionality, or improve their aesthetic appeal.
To deliver a truly finished component, Shenpeng provides a comprehensive suite of secondary operations. This eliminates the need for clients to manage multiple vendors and streamlines the supply chain. These processes are performed in-house under the same rigorous quality standards as our stamping operations, ensuring consistency and timely delivery from a single source.
Quality is not an afterthought at Shenpeng; it is integrated into every step of our manufacturing process. From initial material certification to final part inspection, our quality assurance team employs a multi-layered approach. We utilize advanced measuring equipment, including Coordinate Measuring Machines (CMM), optical comparators, and custom gauges, to verify that every dimension of a part aligns perfectly with the customer's blueprint. Our commitment to ISO 9001 standards ensures a systematic and documented approach to quality management, providing our clients with complete confidence in every shipment.
