Repair zinc die cast parts with Super Alloy 1 and Heat Freeze.
An ornamental zinc die cast piece is repaired with a propane torch, Super Alloy 1 low temperature solder and Heat Freeze Heat Paste. In this clip, a Bernzomatic torch is used to reattach several missing legs from an antique white metal dog statue.
Before soldering, Heat Freeze is utilized to act as a jig, holding the legs in place while they are reattached.
Next, dip the solder rod into the liquid flux and paint the flux onto the area to be repaired. The flux will transform from a honey color to root beer brown, indicating when to add the rod. Super Alloy 1 can be used to reattach the missing pieces, then additional solder and flux can be applied as necessary to fill low spots.
Notice how the solder is applied with quick movements in and out to ensure that the soldered legs do not re-melt and fall off. Heat Freeze can also be used to absorb heat and prevent remelt while working on the remaining 3 broken zinc die cast pieces.
After repairing the zinc die cast part, simply wash the residual flux off with warm water.
TIPS:
- Always use adequate Heat Freeze Heat Paste to ensure your part is fully protected.
- Always allow your part to cool completely before removing the Heat Freeze Heat Paste for your safety and the safety of your part.
- Keep Heat Freeze Heat Paste clean to ensure long life of the product
- For best results, occasionally add water to Heat Freeze Heat Paste as necessary to keep moist.
- Allow adequate space between Heat Freeze Heat Paste and the area to be welded. Heat Freeze Heat Paste works so well it can absorb the heat from the area needing to be repaired.
- Wash hands after handling Heat Freeze Heat Paste or use gloves to apply.
