PEKO manufactures custom sheet metal enclosures for OEM equipment, electronics, and control systems. Our team works with customers to create enclosure solutions that are built around the functional needs of the application, from protection and access to mounting, durability, and integration into larger machines and assemblies. We support those programs with engineering input, precision fabrication, finishing, hardware installation, and production-ready execution.
A Custom Enclosure Manufacturer for Complex OEM Programs
PEKO is built to support enclosure programs where manufacturing requirements extend beyond the enclosure itself. Many OEM products require the enclosure to fit within a broader assembly strategy, meet quality and durability expectations, and support a production process that is consistent over time. In those cases, the enclosure supplier needs to contribute more than fabrication capacity.
PEKO brings that broader support to custom sheet metal enclosure programs through engineering input, precision fabrication, finishing, hardware installation, and production-ready execution. This makes us a strong fit for complex equipment, multi-part assemblies, and other OEM programs where stronger manufacturing control can help reduce downstream issues and improve repeatability.
Sheet Metal Enclosure Fabrication Capabilities
PEKO offers sheet metal enclosure fabrication services across a range of enclosure types, sizes, and production volumes. Our in-house capabilities are designed to support both the functional requirements of the enclosure and the broader manufacturing needs of the program.
Core sheet metal fabrication capabilities include:
- Laser cutting
- CNC punching
- Forming and bending
- Precision welding
- Hardware insertion
- Sheet metal assembly
- Coating and finishing
We build around application-specific requirements such as structural needs, internal mounting, cable routing, access points, and cosmetic expectations.
Custom Enclosure Design & Engineering Support
Successful enclosure programs start with sound design decisions. PEKO supports custom enclosure design with sheet metal engineering input that helps improve manufacturability, control cost, and reduce downstream production issues, including:
- Drawing and specification review
- Design for Manufacturability and Assembly (DFMA)
- Cost-reduction recommendations
- Feature simplification for fabrication
- Hardware and mounting strategy refinement
- Recommendations to improve fit, access, and serviceability
- Preproduction enclosure prototyping and iteration
For OEM teams preparing a new product launch or transferring production, early engineering collaboration can help reduce rework and improve repeatability.
Build Options for Custom Sheet Metal Enclosures
Design Features
Custom sheet metal enclosures can be configured with a broad range of functional and cosmetic features. Depending on your application, PEKO can support features such as:
- Radius corners and partial radius corners
- Doors and removable panels
- Mounting frames and brackets
- PCB guides
- Pass-through holes for conduit and cable management
- Gland plates and cable gland access points
- Internal mounting provisions for electrical or electronic components
- EMI or RF shielding considerations
- Sealing features for environmental protection
These options are especially important when the enclosure must protect sensitive electronics, support operator access, or integrate cleanly into a larger machine or system.
Common Materials
We manufacture precision sheet metal enclosures in a range of common materials, depending on strength, weight, corrosion resistance, and end-use environment. Common materials include:
- Cold-rolled steel
- Stainless steel
- Aluminum
For example, a custom aluminum enclosure may be the right choice when weight matters, while stainless steel may be better suited for harsher environments or applications that require higher corrosion resistance.
Finishing Options
PEKO offers finishing options that allow OEMs to align sheet metal enclosure design with performance, durability, and appearance requirements. Available options include:
For some programs, finishing also supports labeling, branding, or long-term protection in demanding industrial settings.
Common Applications for Custom Sheet Metal Enclosures
PEKO manufactures custom sheet metal enclosures for a wide range of OEM applications, including:
- Custom electrical enclosures
- Electronic equipment enclosures
- Industrial control panel enclosures
- Custom sheet metal boxes
- Machine enclosures
- Rack mount enclosures
- Sheet metal chassis
- Sheet metal housings
Why OEMs Choose PEKO for Custom Enclosure Fabrication
OEMs choose PEKO when they need a custom enclosure manufacturer with more manufacturing discipline and broader support than a standard fab shop can provide.
PEKO is a strong fit for programs that require:
- Engineering support before release to production
- Precision sheet metal fabrication for complex enclosure designs
- Consistency across low-volume and ongoing production
- Better control of documentation, revisions, and manufacturing quality
- Integration with assembly and larger equipment manufacturing needs
For OEMs managing risk, lead times, and supplier complexity, that added support can make sheet metal enclosure fabrication more predictable and easier to scale.
