How are the castings made?
The Bowmanville Foundry employs the green sand casting process. Green sand is by far the most diversified molding method used in present casting practices. The process utilizes a mold made of compressed or compacted moist sand. The term "green" denotes the presence of moisture in the molding sand, and indicates that the mold is not baked or dried. The mold material consists of silica sand mixed with a suitable bonding agent (clay) and moisture. To produce the mold a flask, a metal frame, is placed over production tooling in the form of a pattern or matchplate of the desired part shape. Molding sand is compacted in the flask and takes on the shape of the pattern to produce a cavity representing one half of the casting. Compaction is achieved by squeezing the mold. The other half of the mold is produced in like manner, the pattern and flask is removed and the two mold halves are positioned together to form the complete mold. Molten iron is poured into the cavity in the sand mold through an opening called the sprue. If the casting has hollow sections, a core consisting of hardened sand (baked or chemically hardened) is used.
How do I get production tooling for my part?
The Bowmanville Foundry will make all arrangements for the production of your tooling. Your part quote will include a quote for tooling.
Who designs the production tooling?
The Bowmanville Foundry will design your tooling. However you are responsible for your part design.
How are part designs communicated?
We can receive parts designs in a number of ways. Production tooling can be made from wood, epoxy or metal models, paper drawings, or electronic CAD files sent on disk or email. Increasingly, CAD files are being used as they can reduce the cost of tooling by reducing CNC programming time.
Who owns the production tooling?
All production tooling belongs to the customer. Typically it is stored at the foundry.
How long does it take to get production tooling made?
Depending on complexity, tooling can be produced in one to four weeks.
How much does production tooling cost?
Depending on complexity, and whether or not coreboxs are required tooling ranges from $2500 to $6000.
How long does it take to get castings?
Once the customer has approved samples from their tooling castings can be delivered as quickly as one week later to accommodate customer emergencies. Typical lead times are four to eight weeks depending on current business conditions.
Can I get finished (ie machined, painted, plated, etc.) parts direct from the foundry?
Yes, the Bowmanville Foundry will supply you with a completed part. We will arrange for all post processiing and take full quality responsibility. This service can significantly reduce complexity for the customer. The Foundry arranges all transportation between post-processing suppliers and coordinates all quality and engineering issues. This "one-stop-shopping" approach always proves more cost effective by eliminating unneccesary overhead and duplication of effort.
Can I get parts shipped FOB my dock?
Yes. The Bowmanville Foundry makes all shipping, brokerage, customs and duty, and related arrangments. You only have to deal with us.
What are the business Terms and Conditions?
See attached (Terms and Conditions)
Will a Foundry representative visit my Company?
We will be happy to send a technical/sales engineer to your facility to assess your needs and requirements.
Can I visit the Foundry?
We are very proud of our modern, clean foundry. We will be happy to host your visit. If visiting our facility is difficult to arrange, we have produced two short videos about our foundry. We would be happy to send you copies.
