Precision Metal Slotting for Functional Design and Assembly

Unlock design flexibility with Dexter Steel’s expert metal slotting services

Fabrication Services

Advanced Slotting Service

We create clean, accurate slots for adjustment, ventilation, mounting, and assembly in sheet and plate metal. Our capabilities allow for complex patterns and tight tolerances, ensuring your components function as intended. From prototypes to high-volume runs, we deliver the precision your designs demand.

Our CNC Turret Punch Press offers rapid, cost-effective cycling, creating slots up to 12.5mm wide in a single hit. For thicker materials, complex geometries, or when a burr-free edge is critical, we utilize Fiber Laser Cutting, which can produce slots with a width as narrow as 1mm in plates up to 25mm thick

The critical dimension of the narrow side of the slot. Maintaining a consistent and accurate slot width is essential for the fit of the mating part, such as a bolt or tab.

A through slot is cut entirely through the material. A blind slot, also known as a pocket, is a depression that does not cut through the entire workpiece.

A common fabrication technique where a tab on one part fits precisely into a slot on another, creating a strong, self-aligning joint for welding or assembly.

Frequently Asked Questions

What is the minimum slot width you can achieve?

With our fiber laser, we can achieve slot widths as narrow as 1mm, depending on material thickness. For punching, the minimum width is limited by tooling, typically around 2.5mm.

Can you create curved or irregularly shaped slots?

Yes. Our CNC laser cutting technology is perfect for producing slots with complex, non-linear shapes that would be impossible with standard punching tools.

How do you manage burr on slotted parts?

We offer deburring as a standard secondary service. Laser-cut slots have a minimal, often acceptable burr, while punched slots typically require mechanical deburring for a smooth edge.

What file format do you need for a custom slotting job?

We prefer vector-based files such as .DXF or .DWG, but we can also work from detailed .PDF drawings with all slot dimensions clearly defined.
