If you're looking to bring a design idea to life, GW have the experience, innovative-mindset, and equipment to make it happen.


Fill in the form and we'll be in touch to discuss your project.

If you can provide as much detail as possible that will help us to get us up to speed on the parts you need for rapid prototyping or MLP.

Still considering your options?

We are able to adapt our services to suit your needs.  If you already have a frozen design specification but need a trusted partner to make it, take a look at our rapid prototyping solution.  If you're looking to mimic production parts, we can engineer prototype parts to reflect a finished product.

Rapid Prototyping

For projects with a frozen design requiring rapid turnaround

Core Service

Typically, an 8-week turnaround (depending on complexity and volumes). 

We will agree a quantity of "Fit for Function" parts to be delivered within an aggressive timescale.

Delivery follows the GW process of simulation, engineering, tooling, casting, machining, and validation.

Customer provides a frozen design, including cast and machining 3D data, 2D machining drawings.

Make Like Production

For projects that need to mimic production quality, fast.

Core Service

In addition to our rapid prototyping solution, Grainger and Worrall will work with you to develop the design for manufacture optimising for the casting process.  

Typically, an additional 4-weeks of design time is added to the rapid prototyping lead times.

Our engineering team will develop solutions to meet customer's exacting specifications such as defined material property tolerances, specific alloy compositions, tightly controlled dimensional accuracy.


New to prototyping using sand casting?

Prototyping with sand casting offers greater flexibility than many other methods.  It affords you much greater scope for design modifications, cheaper tooling, and reduced lead times.

Despite what many people think, sand casting can beincredibly complex.  That's why we have put an ebook together to help take you through the basics so you know what you're buying.
