How to Hang Workpiece Properly in Thermoplastic Coating Dip Process?
Some of the suggestions below may not be the best, but you can try using them. If you have a better method, feel free to share it with us.
When there are no hang holes or any place on the surface to hang the workpiece, how can we hang it better?
- Method 1: Use a very thin wire to bind the workpiece. After the dip coating process is completed and the coating is cooled, simply pull out or cut off the wire.
- Method 2: Use spot welding to weld the wire onto the workpiece. After the diping process is completed and the coating is cooled, cut off the wire.
Both methods above will leave a small scar at the hanging point. There are two methods to deal with the scar:
- Method 1: Heat it with fire to melt the coating beside the scar and make it flat. Please Keep the fire source a little far away to prevent it from turning yellow.
- Method 2: Wrap the hanging point with aluminum foil and then iron it with an electric iron.
If the scar hole is too large, there are two remedies:
- Method 1: Fill the hole with a little powder and heat it with a blowtorch (the distance of the blowtorch should not be too close to prevent it from turning black).
- Method 2: Spray automotive epoxy paint on it.
