Custom OEM Metal Doors, Panels, & Drawers

From our fully automated S4+P4 lines, to our Salvagnini P4L-3220, to our fleet of workhouse panel benders, punching machines, and automated lasers, Dalsin does American-made high-volume precision panels and doors better than anybody.

• Equipment access doors
• Utility truck doors and drawer fronts
• RV and transportation panels
• Electrical cabinet and enclosure doors
• Exterior and interior equipment panels
• Control cabinet panels
• Appliance doors and panels
• HVAC and refrigeration panels
• Equipment skins and covers
• Industrial drawers and shelving
• Protective shrouds

The advantage is not one machine or one process. It is the ability to move a door, panel, drawer, or shroud through a modern manufacturing system designed for high-quality production.

Doors and panels are particularly well suited to automated panel bending.

Dalsin’s Salvagnini panel bending systems can form complex profiles with multiple bends, flanges, returns, hems, and edge structures while reducing the need for repeated equipment setups.

Depending on the design, panel bending can also create opportunities for:

• Fewer separate components
• Fewer welds and fasteners
• Fewer manufacturing operations
• Reduced assembly requirements
• Fewer seams
• Increased panel rigidity through formed edge structures
• Greater consistency from part to part

For an OEM, those improvements can affect far more than the price of the formed component. A well-designed panel can be easier to assemble, easier to finish, more consistent at mating surfaces, and simpler to produce repeatedly.

A metal door or panel rarely stops at forming.

The flat sheet may need vents, openings, slots, knockouts, perforations, or mounting features before bending. After forming, the part may require hinges, studs, fasteners, spot welds, structural adhesives or welding, powder coating, or final assembly.

Our capabilities include:

• Automated laser cutting
  
• Automated full-sheet punching
  
• Salvagnini S4+P4 automated manufacturing lines
  
• Salvagnini P4 automated panel bending
  
• Salvagnini P4L-3220 automated panel bending
  
• CNC press brake forming
  
• Robotic and manual welding
  
• In-house powder coating and finishing
  
• Mechanical and electro-mechanical assembly

One of the biggest opportunities in door and panel manufacturing happens before production begins.

Dalsin’s engineering team works with OEM designers to evaluate bend geometry, corner conditions, edge construction, material selection, hardware locations, joining methods, tolerances, and part count.

A design originally developed around conventional press brake forming may use several individual pieces, welds, or fasteners. In some applications, automated panel bending allows those features to be incorporated into a more complete formed component.

The result can be a simpler manufacturing sequence with fewer opportunities for dimensional variation and less downstream assembly.

This Design for Manufacturing approach can be applied to new products or existing designs that need improvements in cost, consistency, production capacity, or manufacturability.

Doors and panels are often among the largest and most visible components on finished OEM equipment.

That makes fit and finish especially important.

A flange that varies can affect the surrounding gap. An inconsistent bend can interfere with an adjacent component. Incorrect hardware placement can create assembly problems. Scratches or handling damage can make an otherwise functional panel unacceptable.

Dalsin combines automated processing, controlled material handling, established quality systems, and in-house finishing to manage these requirements throughout production.

For highly visible components, Dalsin can also process pre-finished and film-protected materials to help preserve cosmetic surfaces through fabrication and forming.

The best time to involve Dalsin is before the print is final.
