Progression
Presswork

Kiyokuni's progression presswork capabilities allow us to perform a wide range of metalworking operations on a single piece of metal, all within the same tool. This includes:

• Forming: Shaping the metal into the desired final geometry.
• Cutting: Creating component shapes by removing material.
• Piercing: Making holes in the material.
• Folding: Creating bends and angles in the metal sheet.
• Embossing: Creating raised lips for hole or patterns on the metal surface.
• Chamfering: Creating recesses for countersunk heads of bolts within the part.
• Marking: Add script or lines on parts to assist it function later.
• Restriking/sizing: Precisely adjusting the dimensions of the metal component.
• Burring: Removing any rough edges left behind from the forming process.
• In-tool tapping: Creating threads directly within the tool during the forming process.

Progression presswork offers many benefits for the mass production of parts, including:

• Increased production speeds: Our progression machines can reach speeds of up to 100 strokes per minute, significantly reducing production times.
• Reduced costs: Progression presswork minimises waste, maximises automation, and streamlines production, leading to lower overall costs.
• Suitable for a wide range of components: While ideal for smaller, less intricate parts, Kiyokuni's expertise allows for creating a variety of pressed components using this method.
• Reduced material waste: By utilising coil material and forming the metal in stages, progression presswork minimises scrap compared to other methods.

A variety of metals can be used for progression presswork, but some of the most common include:

• Mild Steel to high-strength steel
• Stainless Steel
• Aluminium
• Copper/coated stainless alloy

Kiyokuni boasts a range of progression machinery with capacities from 110 tonnes to 400 tonnes, ensuring we have the right tool for your project's specific needs.

Progression presswork offers several advantages that contribute to significant cost reduction, including reduced scrap and labour as well as faster production speeds thanks to fewer secondary options.

• Minimal scrap: By utilising coil material and forming the metal in stages within a single tool, progression presswork minimises scrap compared to other methods that might require multiple steps and generate leftover pieces. This translates to reduced material waste and lower overall production costs.
• Reduced labour: Progression presswork is a highly automated process. Once the tooling is set up, the machine can operate with minimal human intervention, significantly reducing labour costs compared to processes requiring manual handling and operation of separate machines for each stage.
• Faster production speeds: The multi-stage nature of progression presswork allows for continuous forming of the metal in one pass. This translates to faster production speeds per unit compared to processes requiring multiple steps or setups. With faster production comes the ability to fulfil larger orders more efficiently, potentially reducing overall production costs per component.
• Reduced need for secondary operations: Progression presswork tooling can often perform a variety of operations within the same tool, such as sizing, burring, and cutting. This eliminates the need for secondary processes on separate machines, further streamlining production and reducing overall costs.

We source our high-quality tooling from our selection of toolmaking partners in the UK, Japan and Malaysia.

Kiyokuni can design and manufacture bespoke tools tailored to your specific part requirements. Alternatively, we can work with your existing tooling, making modifications as needed.

For complex projects, we rely on our extensive network of trusted tooling partners to ensure the highest quality and efficiency. Our goal is to provide you with the best possible tooling solution to meet your production needs.

While progression presswork is versatile, material thickness does play a role in its suitability. Our expertise lies primarily in working with materials up to 5mm thick. For thicker materials, other metalworking processes might be more appropriate. However, we encourage you to discuss your specific requirements with our team, as there may be exceptions or alternative solutions available.
