Silicone for Bronze Foundy Casting

Description

Do you want to make things out of bronze metal? Our special silicone helps you do that! It’s great for bronze foundry casting. This means pouring hot, melted bronze into a shape, called a mold, to make something new.

Our silicone mold making material is easy to use. It helps you copy shapes perfectly. It works well for the lost wax technique, also called investment casting silicone. People use this to make art and important parts. This is a key part of the bronze casting process.

Why Our Silicone is Great:

• Stands Up to Heat: Bronze gets very hot! Our high-temperature silicone can take the heat. It has good thermal stability.
• Copies Every Tiny Detail: Make shapes look exactly like your first model. Get good surface finish quality. This is important for pattern replication.
•  Strong and Tough: Our RTV silicone molds are strong. They are tear-resistant silicone. You can use them many times. This helps with metal casting durability.
• Easy to Use: It pours easily and sets well. Check the curing time for silicone. It has low-viscosity silicone
• Less Sticking: Things come out of the mold easily. You might not need mold release agents or mold lubrication. We also have silicone mold repair

What You Can Make:

You can make many things with bronze alloy casting and our silicone elastomers:

• Art:Statues and pretty things (Bronzing artistic casts).
• Parts for Boats:Strong parts that don’t rust easily (Aluminum bronze alloys, Tin bronze composition).
• Machine Parts:Like bushings and bearings (C93200 SAE 660 bronze, C95400 aluminum bronze).
• Valves:Parts that control water or air (Custom silicone bronze casting, Valve Casting).

How People Make Bronze Things:

There are different ways, called foundry mold materials and methods:

1. Investment Casting:Using wax shapes (Wax injection molds, Lost wax technique). This needs ceramic shell molds
2. Sand Casting Molds:Using special sand to make the shape (Silica sand alternatives, Cold box cores).
3. Centrifugal Casting:Spinning the mold fast.
4. Shell Molding Process:Making a thin shell mold.
5. Vacuum-assisted casting and Pressure casting methods: Using air pressure to help fill the mold.

Making Good Bronze Shapes – Tips:

      1.) Good Metal: 

Use clean bronze (Slag removal techniques, Dross removal). Check the alloy composition analysis. Use foundry flux agents. Maybe add grain refinement additives. Understand eutectic alloys.

     2. ) Good Pouring:

• Pour at the right heat (Pouring temperature). Let it cool right (Chvorinov’s rule, Metal shrinkage rates). Avoid hot tear prevention. Understand molten metal flow.

• 3.) Good Molds:

• Make molds strong (Mold compression strength). Let air out (Mold venting systems, Draft angle requirements). Make sure parts fit (Mold registration marks). Avoid holes (Defect prevention (porosity), Gas porosity prevention). Design the mold cavity design well, including sprues and risers and the gating system design. Think about mold undercuts. Use mold wash coatings if needed. Make sure the silicone rubber hardness is right. Consider flame retardant molds for safety. Check silicone mold lifespan and mold aging resistance. Understand metal-mold interaction.

• 4.) Finishing:

• Cut off extra metal (Degating and trimming). Make it smooth (Post-casting machining). Check for problems (Nondestructive testing, X-ray inspection, Microstructure analysis). Treat the metal if needed (Heat treatment of bronze, Stress relief annealing). Make it look nice (Patination techniques). Test how hard it is (Bronze hardness testing). Ensure it meets casting tolerances. Check how it slides (Tribological properties).
