Custom 19” Rack Mount Chassis – 1U to 5U Server Cabinet Enclosures
Drawing-Based Rack Enclosure Manufacturing
Custom 19-Inch Rackmount Chassis from 1U to 5U
Hongming Sheng manufactures custom rackmount chassis, front panels and sheet metal enclosures for servers, network equipment, industrial controls, power electronics, audio systems and test equipment. Every project is reviewed against the customer’s rack interface, internal layout and production requirements.

1U–5U: Start with the Rack Envelope
1U44.45 mm nominal
2U88.90 mm nominal
3U133.35 mm nominal
4U177.80 mm nominal
5U222.25 mm nominal
Engineering note: These are nominal rack-unit heights. Actual chassis height is normally designed with installation clearance. Front-panel width, mounting holes, rack ears, slide rails and depth should follow the customer’s selected rack standard and approved drawing.
Configuration Details That Affect the Design
RACK INTERFACE
Mounting & Installation
U height, rack-ear geometry, mounting-hole pattern, handles, slide rails, rear support and allowable installation clearance.
INTERNAL LAYOUT
PCB, Power & Components
Board locations, standoffs, power supplies, fans, drives, connectors, cable routing and service access.
PANEL DETAILS
Openings & Identification
Display windows, switches, connector cutouts, ventilation, labels, serial markings, screen printing and laser marking.
STRUCTURE
Strength & Assembly
Material thickness, folds, stiffening features, fasteners, removable covers, grounding points and assembly sequence.
Manufacturing Route from Prototype to Repeat Orders
Issues Worth Checking Before the Drawing Is Released
Rack fit: confirm the front-panel envelope, mounting pattern, adjacent-unit clearance and rail compatibility.
Chassis depth: allow space for connectors, cable bend radius, fans, filters and service access.
Panel flatness: long front panels and thin covers may need return flanges or other stiffening features.
Ventilation strength: dense perforations can reduce panel rigidity and influence bending or finish appearance.
Grounding: mark conductive contact areas and coating-mask locations clearly on the drawing.
Assembly sequence: make sure boards, power supplies and fasteners remain accessible after bending and welding.
System-level validation: Thermal performance, airflow, payload capacity, EMC behavior and product safety depend on the complete equipment design. We manufacture the metal parts to approved drawings and agreed inspection requirements; the customer or system integrator should define and validate complete-system performance unless a separate test scope is agreed.
