01 / What We Fabricate
Baffles and Deflectors Built Around Airflow Direction
Baffles guide air, block heat, separate zones and protect sensitive areas. We manufacture them around bend angle, mounting interface, gasket fit, thermal exposure and assembly clearance.
Thermal and Zone Separation
Heat shields, divider plates and internal partitions isolate hot areas or separate equipment compartments.
Mounting and Service Access
Slots, tabs, PEM hardware and removable interfaces are planned around installation and maintenance access.
Finish and Edge Control
Edges, coating, gasket surfaces and visible faces are protected through inspection and packout.
Our scope: air baffles, deflectors and internal sheet metal guides
We fabricate the baffle geometry, slots, tabs, hardware, finish and packout. Your team defines the final airflow target, thermal validation and equipment-level performance requirement.
02 / Baffle & Deflector Types
Airflow Components for OEM Enclosures and Equipment
We support baffle programs where airflow, heat control, service access and line-side installation need repeatable sheet metal geometry.

04 / Manufacturing Process
From Air Path Review to Finished Baffle Kits
01
Air Path and Interface Review
Review airflow direction, bend angles, clearance, hardware, gasket surfaces and service access.
02
Cutting and Forming
Cut blanks, punch slots and holes, then form angles, lips, vanes and flanges.
03
Hardware and Gasket Prep
Install PEM hardware, add bracket tabs or prepare gasket channels and cable pass-throughs.
04
Deburring and Surface Prep
Control edges, burr direction, visible faces and thermal shield surfaces before finish.
05
Angle and Fit Inspection
Check bend angles, hole fit, gasket surfaces, hardware retention and finish quality.
06
Kit Packout
Pack baffles by SKU, airflow zone and assembly station with surface and edge protection.
05 / Why It Matters
What Makes a Baffle Program Reliable
Baffles are often hidden inside equipment, but small geometry errors can change airflow, service access, thermal performance and assembly time.
Bend Angle Repeatability
Air direction depends on consistent angles, lips and vanes across production lots.
Clearance and Service Access
Internal baffles need to fit around cables, fans, filters and removable service panels.
Thermal Surface Control
Heat shields and deflectors need the right material, finish and standoff geometry for the environment.
Kit-Level Packout
Baffle families need clean SKU and airflow-zone separation so assembly teams install the right part quickly.
