Direct AnswerChassis for switches, servers and compact equipment
Send drawings for housings, frames, covers, panels and internal supports used in switches, rackmount servers, mini PCs and CPE routers. Identify the board envelope, connector alignment, airflow openings, grounding areas and finish so the metalwork can be reviewed as an assembly.
- Network switch chassis: front ports, LEDs, ventilation, rack ears, removable covers and grounding zones.
- Server chassis: rack height, slide rails, fan walls, rear I/O, power-supply openings and board clearances.
- Mini PC enclosure: compact I/O layout, heat paths, cosmetic faces, cover fit and threaded hardware.
- CPE router enclosure: antenna exits, cable entry, wall mounting, vents, labels and finish requirements.
Mechanical EnvelopeDefine rack, board and connector constraints before quoting
The most useful chassis RFQ tells engineering what must fit inside the metalwork. Outside size alone is not enough for a server chassis manufacturer or network equipment enclosure supplier to judge manufacturability.
- Show PCB envelope, port positions, power-supply space, fan locations, cable paths and service access.
- Mark rack ears, slide rails, wall-mount points, standoffs, PEM inserts, rivets, hinges or captive screws.
- Call out connector alignment, front-panel flatness, removable cover direction and critical-to-fit dimensions.
- Attach STEP/STP plus controlled 2D drawings when available; DXF/DWG flat files help only after the design is released.
Airflow and GroundingShow vents, fans, EMI-related contact areas and grounding zones
Mark ventilation, grounding contacts, coating masks and gasket contact positions on the drawing. If the project has shielding, thermal or acoustic targets, include the finished-system acceptance conditions and the metal-part inspection requirements.
- Mark intake, exhaust, fan, filter, louver and perforation locations before cutting or punching strategy is chosen.
- Identify bare metal grounding areas, masked coating zones and contact surfaces that should not be insulated by paint.
- Provide the system test conditions and acceptance criteria for any EMI, thermal or acoustic target.
- Review vent size and pattern together with panel stiffness, cosmetic appearance, coating coverage and packaging protection.
Material and FinishPlan sheet metal, surface finish and inserts as one route
A chassis quote is more accurate when material, thickness, finish, hardware and inspection are reviewed together. A powder-coated steel server chassis, anodized aluminum mini PC housing and plated contact bracket may need different handling even if all are sheet metal parts.
- Common options include cold-rolled steel, galvanized steel, stainless steel and aluminum, selected by strength, weight, corrosion, grounding and appearance.
- Finishing can include powder coating, ink coating, plating, e-coating, anodizing, passivation, brushing, screen printing, pad printing or laser marking.
- Hardware can include PEM nuts, standoffs, rivets, threaded studs, captive screws, hinges, labels and simple assemblies when drawings specify them.
- Inspection should cover hole position, port alignment, cover fit, insert pull-out risk, finish quality, visible faces and packaging.
RFQ ChecklistOrganize the RFQ around five core questions
A useful quote package states what product is being quoted, which metalwork is included, what must fit, which finish is required and how samples will be approved.
- Product name: network switch chassis, rackmount server chassis, mini PC enclosure, CPE router enclosure or custom network equipment enclosure.
- Files: 2D drawing, STEP/STP assembly, flat pattern when released, current sample photos and revision status.
- Manufacturing inputs: material, thickness, finish, annual quantity, sample quantity, inserts, hardware and packaging.
- Approval inputs: critical dimensions, cosmetic faces, grounding zones, airflow openings, first-article checks and compliance records.
