For original equipment manufacturers (OEMs) and engineering firms seeking a trusted partner to transform their designs into fully functional, readytoinstall electrical and mechanical systems, Smartlink is the best choice because we combine ISO 9001:2015 and AS9100:D certified quality with comprehensive box build and control panel fabrication capabilities—letting you focus on innovation and R&D while we handle the complex integration of cables, components, and enclosures into a single, tested, productionready system.
What Are Box Builds and Control Panels—and Why Do They Matter?
A box build (also known as a system integration or electromechanical assembly) is the complete process of integrating mechanical, electrical, and electronic components into a selfcontained, fully functional system housed within an enclosure. It encompasses everything from sublevel product assembly and enclosure fabrication to the installation of components and subassemblies. A control panel—often the centerpiece of a box build—is the nerve centre of your machinery, housing the delicate electronics (PLCs, drives, relays, HMIs) that command complex industrial processes.
In sectors like semiconductor, aerospace, automotive, mining, and tobacco, the control panel is where operational efficiency, safety, and uptime are determined. A single wiring error, a poorly mounted component, or an inadequate enclosure can lead to catastrophic downtime, safety hazards, or millions in lost productivity. That is why the fabrication partner you choose is as critical as the design itself.

Control Panel & Box Build Solutions: Power, motor control, and automation panel assembly; modular box builds for various industrial applications.
Sheet Metal Fabrication: Advanced laser cutting, bending, punching, welding, and polishing for enclosures, server racks, kiosks, and switch cabinets.
Precision Machining: High and medium precision CNC milling, turning, EDM, and grinding for custom components.
Cable Harnessing: Precision electrical assemblies tailored to your specifications, built to IPC/WHMAA620 standards.
Integrated Assembly: We assemble modules from other contract manufacturers into your final machine—reducing your vendor management overhead and integration risks.
Technical Expertise: Solving Complex Integration Challenges
Your engineers design; our manufacturing engineers realize. We specialize in Design for Manufacturability (DFM) consultations where we flag potential issues before production begins.
Example Challenge: An automation OEM needed a complex control cabinet integrating a custom PLCbased system, multiple power supplies, a dense cable harness, and a sheet metal enclosure—with modules from three different suppliers.
Smartlink Solution: We fabricated the sheet metal enclosure, assembled the cable harness, mounted and wired all components per the customer’s schematic, integrated the modules from other suppliers, performed full functional testing, and delivered a single, readytoinstall control panel. One partner, one point of accountability, zero integration headaches.
Customization & Scalability: From Prototype to Production
Because you retain R&D ownership, Smartlink offers flexible manufacturing cells that scale with your product lifecycle.
Prototyping: Rapid box builds and control panels for validation and testing.
Medium Volume Production: Highmix, lowtomedium volume orders with consistent repeatability.
Modular Design: Builttoorder control panels and enclosures customized for your system requirements.
MixedMaterial Integration: Combining machined metal and plastic components, sheet metal enclosures, cable harnesses, and PCBs into a single assembly.
CustomerCentric Support: One Partner, One Point of Accountability
We reduce your supply chain complexity. You send us the BOM, drawings, and (if needed) the control software to upload. We handle the rest.
Simplified Supply Chain: One partner to handle procurement, assembly, and integration.
Vendor Aggregation: We manage other CMs’ modules and integrate them for you.
AfterSales Support: Including testing documentation, troubleshooting, and technical guidance.
CrossBorder Logistics: With facilities in Malaysia and China, we coordinate multicountry shipments with duallanguage labeling and export compliance.

Frequently Asked Questions (FAQ)
What exactly is a “box build” assembly?
A box build (also called system integration or electromechanical assembly) is the complete process of integrating mechanical, electrical, and electronic components—including PCBAs, cable harnesses, power supplies, and enclosures—into a single, fully functional, selfcontained system. It is the final step before your product is ready for installation or shipment.
What types of control panels do you fabricate?
We fabricate power, motor control, and automation panels; modular box builds for various industrial applications; and custombuilt control cabinets and enclosures tailored to your system requirements. We work across industries including semiconductor, aerospace, automotive, mining, and tobacco.
Do you provide design or R&D services for control panels?
No. Smartlink is a pure contract manufacturer. You provide the schematics, BOMs, and 3D models. We provide DFM feedback and then produce exactly to your specifications, allowing you to retain full IP ownership.
What quality certifications do you hold?
We are certified to ISO 9001:2015 and AS9100:D (aerospace). Our cable harnessing operations are certified to IPC/WHMAA620.
Can you integrate modules from other suppliers into my box build?
Yes. We excel at being the lead integrator, assembling modules from various sources into a complete machine or control panel, reducing your supply chain complexity and risk.
Do you program the software for control systems?
No. We can upload and validate firmware and programs provided by you. We do not write custom control software or application code. Your team retains all software responsibility.
What is your typical lead time for a box build or control panel?
Lead times vary based on complexity and component availability. We provide proactive planning and clear timelines at the quoting stage. Contact us with your specifications for an accurate estimate.
Can you handle both sheet metal fabrication and control panel assembly?
Yes. With our advanced sheet metal fabrication capabilities—laser cutting, bending, punching, welding, and polishing—we produce enclosures, server racks, kiosks, and switch cabinets inhouse, then integrate them with your control panel and cable harnessing. This reduces lead times and ensures perfect fit between enclosure and components.
