What do I need to provide to receive a quote for a custom extrusion,metal, plastic injection mould?

Answer: 

We can use a drawing (printed, CAD, PDF, JPG etc.) including specified tolerances and quantities or a written description including a list of dimensions, color, material, tolerances for the extrusion die & metal stamping dies. 
Also for plastic injection dies/moulds we prefer to receive its product 3D drawing (format .igs, .stp).
For all moulds, its sample is very helpful.
If in doubt, it is best to contact us and let us help you determine what is needed to accurately quote your product.
