Fabricated Metal Parts Finishing Systems

Part Mix and Loading Methods

A finishing area for fabricated metal parts has to work with changing shapes, weights and rack styles. Some parts hang from a conveyor, some move on carts and some need fork truck access. Planning starts with the largest part envelope, the normal production rhythm and the way operators need to reach edges, seams, corners and masked surfaces.

• Confirm maximum part length, width, height and weight before equipment layout begins.
• Identify whether parts will be hand carried, carted, hoisted, racked or conveyed.
• Leave room for staging, inspection, masking and rework without blocking booth doors or oven access.

Prep, Blast and Coating Flow

Surface preparation often drives the success of the finish. Blast rooms, abrasive booths, wash areas, paint booths, powder booths and cure ovens need to be arranged so parts do not cross back through dirty work zones after cleaning. The best layout keeps abrasive media, powder overspray and wet coating activity separated enough for operators to maintain quality and housekeeping.

Air, Exhaust and Cure Requirements

Fabricated metal finishing may combine booth exhaust, make-up air, heated air, powder recovery, cure ovens and fire protection interfaces. The system has to move enough air for the booth style while also protecting building pressure and operator comfort. Duct routing, fan locations, roof penetrations, filters and service clearances all need to be reviewed before installation work begins.

Utility and Maintenance Access

Booths and ovens need dependable electrical, gas, compressed air and control connections, with safe access for filter changes, burner service, fan work, lighting maintenance and conveyor adjustments. Double D Mechanical coordinates equipment placement with the plant layout so maintenance teams can reach the components they will need after the system is running.

• Gather equipment drawings, utility points, roof structure notes and existing duct information before a site visit.
• Mark floor drains, cranes, columns, sprinkler lines, panels and high traffic aisles that affect placement.
• Plan shutdown windows around production, rigging, electrical work and other trades.
