brass door knocker molding
The brass door knocker selection offered by Your-Door-Knocker is produced in foundries by the sand casting method. This method involves pouring molten brass into a mold made of sand and letting it cool to form a casting.
In our foundry we produce small parts and door knocker components in this manner. We describe this operation at these pages of our site. At The Foundry
This ancient technology is used in many industries producing a large variety of items. Everything from high precision machined parts to plumbing components to ornamental items such as our brass door knockers.
Casting of brass using the sand casting method is an important element in the manufacturing industry. I doubt that any one of us has not had need or use for a cast brass item at some time or another.
Not all of our door knockers are produced in our foundry. It is small and designed for prototyping and very small production runs. Our larger quantities are produced in production foundries that are set up for this type of production.
The foundry operation can be quite dangerous if not done properly. The handling of 1800F to 2000F molten brass is not for the meek of heart. A foundry operation either large or small must be an extremely safety conscience work place.
With proper planning and careful manufacturing methods the foundry like most manufacturing processes can be done by skilled personnel using good equipment.
There are other methods used today to produce some brass door knocker styles but the good old sand casting method is still one of the best.
