Masking hanger

Masking hangers are jigs used on painting lines to suspend and convey workpieces during coating. Tiered level bars or beams are mounted in steps on shafts or frames that hang from the conveyor, and workpieces are hung from the hooks or sockets at their tips. Main configurations include the quick level bar type, which arrives with hooks fitted and is ready to use; the socket type, whose tip inserts can be replaced; and the beam type, whose hooks can be exchanged. Tier count and combinations can be varied to handle many product types. They are also used in powder coating and electrodeposition coating processes, where the hanger provides electrical conduction and grounding.

How to choose Masking hanger

  1. 1. Determine hanging quantity to suit workpieces

    The number of workpieces that can be hung at once directly affects line throughput. Listed models allow 4 to 18 pieces per hanger. Determine the appropriate number per hanger from the workpiece size and the effective dimensions of the painting booth, and select a quantity that avoids uneven coating and contact caused by overcrowding.

  2. 2. Check layout by socket count and pitch

    Socket-type hangers offer 4 to 30 sockets with pitches of 50 to 200 mm. If the pitch is narrower than the workpiece width, adjacent pieces will interfere and paint coverage will be poor. Confirm that the spacing allows a margin beyond the workpiece outer dimensions.

  3. 3. Evaluate load capacity and contact area by wire diameter

    Wire and shaft diameters range from 1.5 to 12 mm. Thicker sections offer greater rigidity and suit heavy workpieces; heavy-duty shafts are intended for this application. Thinner sections reduce contact marks on workpieces and paint pooling. Select based on weight and finish requirements.

  4. 4. Match overall length to oven and booth dimensions

    Listed models have an overall length of 1500 to 1530 mm. Check that the hanger fits the height of the drying oven or painting booth and the conveyor pitch. For frame types, also consider the overall footprint, including frame dimension L (1050 to 1550 mm) and tier count (7 to 14 tiers).

  5. 5. Confirm hook wire diameter compatibility

    On beam types with exchangeable hooks, the usable hook wire diameter is fixed, and listed models use 4 mm. Verify in advance that existing hooks and future replacement parts are compatible, so that changes in workpiece shape can be handled by exchanging hooks alone.

  6. 6. Plan for conductivity and removal of adhered paint

    For powder and electrodeposition coating, a structure with contacts placed on the inside to ensure electrical conduction is effective. Types with socket caps that prevent paint intrusion, and types with exchangeable inserts or hooks, allow replacement of only the portions where coating has built up, reducing the effort required for stripping.
