What Two Networks Mean for Your Quote.
A single foundry can only quote you one answer: itself.
GW starts every project with a different question — where is the best place to manufacture this part? — and quotes from both a domestic and an international network of qualified foundries.
For you, that means real options.
And when conditions change — tariffs, capacity, a supplier’s performance — we can move your work without disrupting your supply.
Thousands of Foundries Worldwide.

Joining the network is only the beginning. Staying in it requires meeting GW’s standards every day.
Why Foundries Give Us Their Best Work.
Anyone can email a drawing overseas. Getting a foundry’s attention — fair pricing, honest capacity, priority when it matters — takes something else. GW spent decades running foundries before we managed them. We know what a good pour looks like, what a realistic schedule is, and what to inspect before parts ship. Foundries treat us as peers, not paperwork. You get the benefit of that relationship on every order.
Whatever the Process. Whatever the Project.
The network supports virtually every major casting process and material — plus the managed services that finish the job:
Whether you need a prototype, a pilot production program or a fully managed manufacturing program, one experienced partner runs it from concept through delivery.
One Partner. Complete Accountability.
Every casting assignment has hundreds of details that determine its success. GW manages them all: the right manufacturing partner, production oversight, quality enforcement, logistics, delivery. When you place an assignment with GW, one partner answers for its execution — wherever in the world the part is made.
