Our Metal Stamping Capabilities

Metal stamping is a manufacturing process that utilizes dies and high-pressure machinery to cut, blank, bend, punch, emboss, or shape metal sheets into specific forms and designs with remarkable accuracy and repeatability.Chiggo delivers consistent high-quality metal stamping services, from prototypes to production-level volumes of over one million pieces, all with competitive lead times and pricing. Our press capabilities range from 25 to 500 tons, with a maximum press bed length of 10 feet and a maximum press bed width of 20 feet. We can readily stamp metal thicknesses from .004 to .394 inches (0.1 to 10mm),and work to tolerances of ±0.001″.

Comprehensive Metal Stamping Services

Stamping can be completed in a single stage or through multiple stages, depending on the complexity of your parts. We manufacture custom metal stampings in various materials, including copper, brass, stainless steel, and steel alloys. With a dedicated team for designing, manufacturing, modifying, and maintaining your tooling, we primarily focus on the following stamping processes:

Progressive Die Stamping Services
A continuous process where a metal strip remains attached and moves through a series of stations within a single press, each performing specific operations — cutting, bending, punching, or coining — to form intricate parts efficiently.Ideal for high-volume, consistent production.
Deep Draw Stamping Services
A process where a sheet metal blank is radially drawn into a forming die by a punch, creating deep, seamless shapes and hollow parts. This method produces components with high depth-to-diameter ratios, making it ideal for manufacturing parts like cans, kitchen sinks, and automotive fuel tanks.
Fourslide Stamping Services
Fourslide stamping is a versatile process that shapes parts with multiple bends and angles from four directions simultaneously. This enables the efficient creation of complex parts in high volumes, such as phone battery connectors.
Transfer Die Stamping Services
Unlike progressive stamping, which processes a metal strip through various stations within a single die, transfer die stamping uses individual dies for each operation. Parts are transferred from one station to the next by mechanical handlers, allowing each piece to undergo multiple operations such as punching, bending, and trimming within separate but sequentially arranged dies. This method is suitable for the production of large, complex parts.

Bead Blasting
Achieves a uniform matte finish with a grainy texture, eliminating machining marks or imperfections. This is often a preparatory step for other surface treatments.
Polishing
Produces a glossy surface that enhances visual appeal and minimizes light scattering.
Brushing
Creates a textured, non-reflective finish that effectively masks fingerprints and light scratches.
Brushing + Anodizing Type II
After brushing, parts are dipped in an anodizing bath (Type II). This process increases corrosion and wear resistance, enhances surface hardness, and offers various color options.
Bead Blasting + Anodizing Type II
Following bead blasting, parts are dipped in an anodizing bath (Type II). This improves corrosion and wear resistance, enhances surface hardness, and provides a range of color options.
Anodized Type III (Hardcoat)
Delivers an exceptionally durable finish, significantly improving wear resistance.
Powder Coating
Applies a uniform, durable layer of color to metals, available in many shades for a long-lasting finish.
Black Oxide
Provides a sleek, non-reflective finish that offers mild corrosion resistance and a decorative appearance.
Chromate Conversion Coating
Offers corrosion resistance and improves adhesion for subsequent paint or coating applications, while maintaining electrical conductivity.

Anodizing
Increases corrosion and wear resistance on aluminum laser cut parts, enhancing surface hardness and offering a variety of color options.
Bead Blasting
Achieves a uniform matte finish free of machining marks or imperfections, often a preparatory step before other surface treatments.
Powder Coating
Adds a uniform, durable layer of color to metals, available in many shades for a long-lasting finish.
Electroplating
Provides functional, decorative, or anti-corrosive finishes, with chrome-plating for auto parts being a common use.
Polishing
Produces a glossy surface that improves visual appeal and minimizes light scattering.
Brushing

Custom CNC Machining Solutions: From Concept to Production

From rapid prototyping to small-batch production and onto on-demand manufacturing, Our CNC machining service provides efficient solutions, helping you optimize produ ction processes, reduce costs, and swiftly adapt to market changes.

Low-Volume Production
High Volume Metal Stamping

Low Volume Metal Stamping
Customers use smaller metal stamping orders to bridge the development of a product between prototypes and mass manufacturing, and to gauge how well a product will perform in the market. Low volume production is also beneficial for buyers seeking customized products.

Most stamping projects are at least 5000 units to ensure cost-effectiveness for the customer. When the quantity cannot reach this number, we will consider the customer's specific project requirements (such as part complexity，materials,and surface finish requirements ) and provide various alternative solutions accordingly.
- Laser Cutting: Possibly the quickest and lowest-cost alternative, with the ability to change and adjust programs in minutes but lower material efficiency and tolerance limitations.
- CNC Punching: Another efficient alternative that enables easy program changes, producing parts similar to die-struck components with tight tolerances, though material utilization is not optimal.
- Wire EDM: Offers high precision for complex shapes and fine features, providing excellent surface finish and accuracy, but is slower and more expensive.
- CNC Machining: Delivers high accuracy and flexibility for both simple and complex parts, but is typically slower and costlier.
- Prototype & Soft Tooling: Uses any means necessary, often starting with a laser or Wire EDM cut blank, followed by less durable tooling such as soft materials or simpler construction
- Metal Bending: Involves cutting blanks with technologies like laser or waterjet, then bending them into various shapes, offering flexibility and quick turnaround.
High Volume Metal Stamping
Typically, we define high-volume metal stamping as volumes exceeding 1 million parts. Due to the high scalability of stamping, it significantly reduces the unit cost associated with creating custom tools. However, large-scale metal stamping production also brings unique challenges such as tooling production and maintenance, production efficiency, and quality stability. At Chiggo, we effectively manage these challenges with a range of strategies:
- We use Class A progressive stamping dies with replaceable high-end components, maintaining core tooling as parts wear out.
- With expertise in processing tool steels and carbide materials, we use carbide cutting inserts and apply coatings to reduce wear, minimize downtime, and improve efficiency.
- By stocking spare components, sharpening shims, and other wear items, and regularly inspecting and maintaining tools, we ensure stable production and consistent quality.
- High-volume stamping demands strict quality control, including inspections during setup and production, ensuring batch control and compliance with customer requirements (FAIR, PPAP, CPK data).
- We run multiple shifts, with equipment operating up to 600 strokes per minute (SPM). Certifying tools on various presses keeps production running during maintenance or equipment failure.
- Pre-purchasing materials locks in prices and ensures availability. We can also produce and store parts ahead of time to meet delivery schedules and increased demand.
Rapid Prototyping
Chiggo offers a wide range of metal and plastic materials. Combined with the speed of our skilled machinists, this allows for a quick transition from CAD designs to physical models, enabling designers and engineers to practically assess the product's appearance, dimensions, and functionality.
- Validating design feasibility.
- Testing functionality.
- Optimizing and modifying the design.
