Choosing the right custom metal stamping provider is crucial for ensuring consistent precision, quality, and long-term manufacturing success. With the right partner, you can achieve precision, quality, and efficiency in your manufacturing processes. This article will guide you through essential considerations, including types of metal stamping, practical applications across industries, key supplier features, cost factors, and design guidelines. Understanding these elements will empower you to make an informed decision when selecting a custom metal stamping manufacturer.
What are the types of metal stamping?
Metal stamping encompasses various processes, each tailored for specific applications. The four main types of metal stamping include:
Progressive Die Stamping
This process involves feeding a strip of metal through a series of stations in a single die. Each station performs a specific operation, such as cutting or bending, until the final part is produced. It’s ideal for high-volume production and offers excellent precision.
Understanding how progressive die stamping compares to multi-slide methods can help clarify which approach best fits your part design and production volume. For a deeper comparison, see our blog Difference Between Multi-Slide and Progressive Die Stamping.
Four-Slide Stamping
This method uses a machine with four sliding tools that can perform multiple operations simultaneously. It’s well-suited for complex shapes and is commonly used in industries requiring intricate designs, such as electronics.
Deep Draw Stamping
In this process, a flat metal sheet is drawn into a die to create a three-dimensional part. It is particularly useful for producing parts like cans and containers, often utilised in the automotive and appliance sectors.
Blanking and Punching
These processes involve cutting out shapes from a sheet of metal. Blanking creates a flat shape, while punching removes material to create holes or complex designs. These methods are widely used in various industries, including construction and medical devices.
Understanding the different types of metal stamping available helps you select the process best suited to your application. At Keats Manufacturing Co., all dies and tooling are engineered and built in-house, ensuring that we maintain strict quality control throughout the production process.

What are the key features to look for when choosing a stamping supplier?
Selecting the right metal stamping partner can make or break a program. Beyond getting a competitive price, you need a supplier who can protect your quality, delivery, and long-term total cost of ownership. Here are the key features to evaluate, and how Keats aligns with each.
1. Advanced Technology and Process Capabilities
A modern stamping supplier should be built around high-speed, highly repeatable processes, not just basic presses.
Look for:
- Progressive, coil-fed stamping: For medium to high volumes, this is the backbone of efficient production. A continuously fed strip runs through a progressive die, forming multiple features at once and delivering a finished part with each stroke. Keats specialises in progressive metal stamping from continuous coil, ideal for terminals, connectors, clips, brackets, and busbars that demand tight tolerances at scale.
- Four-slide / multi-slide capabilities: These machines excel at complex, three-dimensional forms, small parts, and intricate bends. Keats operates one of the largest four-slide fleets in North America, which allows us to shape highly complex geometries that would be difficult or costly with standard presses.
- Precision tooling technology: CNC machining and EDM (wire and sinker) are essential to build and maintain high-precision dies. This is what allows repeatable tolerances like ±0.0005 in. in production, not just in theory.
- In-house tooling and die maintenance: A supplier that designs, builds, and services its own tools has tighter control over uptime, quality, and lead times. Keats’ in-house tool and die team supports everything from new die builds to emergency repairs and engineering changes.
Ask potential suppliers to explain which processes they’ll use for your part and why. If they cannot clearly articulate whether your project belongs in progressive stamping, four-slide, or traditional sheet/blank stamping—and the trade-offs involved—that’s a red flag.
2. Deep Experience in Your Part Types and Industries
Years in business matter, but relevant experience matters more.
Consider:
- Part families: Has the supplier produced parts similar to yours, terminals, contacts, lead frames, brackets, clips, busbars, etc. at the volumes and tolerances you need?
- Industry standards: Do they understand automotive PPAP, medical documentation, or electronics cleanliness and packaging requirements?
- Design for Manufacturability (DFM): Can they recommend small changes to thickness, bend radii, hole sizes, or material choices that improve manufacturability and reduce cost?
Keats brings decades of experience in high-precision stampings and assemblies across automotive, electrical distribution, appliance, industrial, and medical applications. That experience translates directly into faster launches, fewer surprises, and more robust tooling decisions up front.
3. Certifications, Compliance, and Traceability
A serious stamping partner needs a mature quality system, not just a certificate on the wall.
Key items to verify:
- Quality certifications: ISO 9001, IATF 16949 (for automotive), ISO 14001 (environmental), and any industry-specific standards relevant to your product.
- Documented procedures: APQP, FMEA, control plans, PPAP, and structured change-control processes.
- Traceability: Lot-level traceability of raw material, process steps, inspection data, and final shipment.
Keats’ ISO 9001, ISO 14001, and IATF 16949 certifications reflect a systemic approach to quality and compliance, not just a checkbox. This is especially important when you’re dealing with safety-critical or high-liability parts.
4. Robust Quality Assurance and Metrology
The best stamping press in the world cannot save you from poor measurement and control. Look at vision systems, CMMs, and SPC charts. At Keats, our quality assurance team is integrated into the stamping process from tool design through to JIT delivery.
5. Tooling Strategy and Die Design Expertise
The sheet metal stamping dies your supplier uses are the heart of the process. Keats’ in-house tool and die group designs progressive dies específicamente optimized for continuous coil feed and high stroke rates.
6. Material and Process Engineering Support
Look for material expertise in brass, copper, and stainless steel. Keats routinely advises customers on material choices that balance performance, formability, and cost.
7. Supply Chain Strength and Delivery Performance
Beyond the press, you need a partner who can support your schedule. We offer The Many Benefits of Just-in-Time Inventory and operate multiple facilities to reduce logistics risk.
8. Customer Service, Communication, and Program Management
Keats takes a customer-centric approach, with engineering, quality, and sales closely aligned so you have a single, coordinated team throughout the life of the program.
When you combine advanced coil-fed progressive stamping, strong tooling and quality systems, deep materials expertise, and reliable program support, you get more than a part—you get a manufacturing partner. That’s the role Keats aims to play: helping you choose the right stamping process (progressive, four-slide, or traditional sheet/blank stamping) and then executing it with the precision, speed, and consistency your business depends on.
How much does it cost to get a die made?
