At Metalstar Prototype, we understand that the raw material is another key factor in determining the success of any deep draw prototype stamping project. That's why we have forged strong partnerships with large-scale raw material suppliers, enabling us to virtually guarantee that we can meet the exact specifications our clients require.

Our extensive network of material providers gives us access to a vast array of steel grades and product types. Whether you need a particular alloy for its strength and formability, or a specialized coated sheet for its aesthetic properties, we can source the optimal raw material to suit your prototype needs. This depth of options is crucial, as prototype parts often demand highly specialized materials that may differ significantly from standard production requirements.
In fact, there are certain instances where the choice of raw material is absolutely critical to the final outcome. Take the part in this page as an example, it was needed as a high-quality enameling-coated prototype part. In this case, we must source a specific steel sheet that is engineered to support the successful application and adherence of the enamel coating. Anything less than the perfect raw material will result in a part that fails to meet the desired aesthetic and functional standards.
Fortunately, with over 20 years of experience in prototype stamping, we at Metalstar have developed unparalleled expertise in raw material purchasing and usage management. Our team of material experts intimately understands the nuances of different steel grades, coatings, and other key properties. We leverage this knowledge to carefully select the optimal raw materials for each unique prototype project, ensuring that the final parts exceed our clients' expectations.
Whether you require a complex alloy for its mechanical properties or a specialty-coated sheet for its visual appeal, you can trust that Metalstar Prototype has the resources and expertise to source the perfect raw material. This, combined with our world-class design, engineering, and manufacturing capabilities, makes us the ideal partner for any prototype stamping challenge.
