— Who We Are
Built for Buyers Who Need More Than a Product List
FN Enclosure works with buyers who need mechanical enclosure structures to match drawings, project interfaces, surface requirements, accessory layouts, and shipment conditions—not simply a standard box selected from a catalogue.
Supported project discussions may include custom electrical enclosure bodies, electrical cabinets, sheet metal housings, mounting structures, doors, panels, cut-outs, cable entries, mounting plates, locks, hinges, gaskets, fans, filters, labels, and packaging.
- Project input first: drawings, samples, photos, sketches, specifications, quantity, and destination.
- Manufacturing scope second: material, fabrication, finish, accessories, inspection, and packing assumptions.
- Quotation after clarification: project-specific requirements are confirmed before production commitments.
Project boundary: protection-rating targets, electrical assembly, certificates, test documents, MOQ, and lead time should be confirmed for the complete project configuration and quotation scope.
How Enclosure Projects Move From Drawings to Shipment
FN coordinates four connected control phases so drawings, fabrication details, finishes, accessories, inspection requirements, and shipment conditions remain aligned with the approved project scope.
Engineering and Scope Confirmation
Review drawing revision, dimensions, material, thickness, openings, interfaces, quantity, destination, and acceptance requirements before production assumptions are fixed.
Fabrication and Joint Control
Prepare material and create panels, bends, hardware points, corners, welds, and structural joints while controlling fit and accumulated dimensions.
Finishing and Mechanical Assembly
Complete surface pretreatment, coating or specified finish, gasket work, and agreed mechanical accessories with protected interfaces and clean assembly.
Inspection and Shipment Preparation
Confirm dimensions, fit, finish, accessories, labels, records, surface protection, packing method, and shipment readiness against the approved scope.

— Buyer Fit
Who We Work With
FN supports buyers who need enclosure manufacturing decisions translated into clear drawings, interfaces, inspection points, and delivery requirements.
OEM Equipment Manufacturers
Custom bodies and housings that must fit equipment, controls, interfaces, and repeat-production requirements.
Panel Builders
Cabinet structures, mounting plates, doors, cut-outs, rails, grounding parts, and accessory coordination.
System Integrators and EPCs
Application-driven enclosures requiring project review, environment inputs, documentation, and shipment planning.
Distributors and Sourcing Teams
Product-family comparison, repeat supply, packaging consistency, destination requirements, and quotation support.
— Customer Engagement
Customer Visits and Face-to-Face Project Conversations
Electrical enclosure projects often begin with detailed discussions about application conditions, mechanical interfaces, materials, quantities, inspection expectations, and delivery requirements.
Factory Visit and Manufacturing Review
Project Discussion at an Industry Exhibition
Product Discussion with International Visitors
Face-to-face conversations with project buyers at an industry event
Application Context
Operating environment, component interfaces, and installation conditions.
Project Inputs
Drawings, materials, dimensions, accessories, quantities, and inspection needs.
Delivery Expectations
Documentation, packaging, destination, timing, and repeat-supply planning.
— Engineering Review
Clarify the Inputs That Affect Fit, Cost, and Delivery
Better RFQ inputs reduce quotation assumptions and help identify enclosure interfaces that must be resolved before a first article or repeat-production order.
Buyers Can Send
- 2D or 3D drawings
- Samples or reference products

— Quality Control
Focused on Fit, Finish, Assembly, and Shipment
Inspection points and documentation are confirmed according to the drawing, project requirements, production stage, and agreed quotation scope.
Project Stage
What Is Checked
Why It Matters to the Buyer
Quotation review
Drawing revision, material, quantity, openings, accessories, finish, destination, and packing assumptions.
Reduces scope gaps before price and lead time are confirmed.
Incoming material
Material type, thickness, surface condition, and project requirements.
Supports the agreed mechanical and finish requirements.
Cutting and forming
Hole positions, cut-outs, openings, dimensions, angles, and cabinet-body shape.
Protects component fit, door alignment, and downstream assembly.
Welding and preparation
Structure, deformation, grinding, surface preparation, and appearance.
Influences body geometry, coating quality, and finished appearance.
Surface and assembly
Coating appearance, color, locks, hinges, handles, gaskets, plates, rails, and agreed accessories.
Confirms the enclosure matches the approved mechanical configuration.
Final inspection
Dimensions, appearance, quantity, labels, accessory list, agreed documents, and packing readiness.
Identifies mismatches before shipment.
Packaging inspection
Surface protection, corners, pallets, crates, separated accessories, and shipment labels.
Reduces avoidable damage and missing-part risk during transport.
The exact inspection plan, sample size, tolerances, reports, and acceptance method should be confirmed for each project.
