Available materials for Die casting

JunYi provide the latest die casting technology to deliver high quality, on-demand parts. Our typical tolerance accuracy ranges from +/-0.003" to +/-0.005" for aluminum, zinc and magnesium, depending on customer specifications.

Available surface finishes for Die casting

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.

Name Description
As-Cast Zinc and zinc-aluminum parts can be left as-cast and retain reasonable corrosion resistance. Aluminum and magnesium parts must be coated to achieve corrosion resistance. Cast parts are typically broken away from the casting sprue, leaving rough marks at the gate locations. Most castings will also have visible marks left by the ejector pins. Surface finish for as-cast zinc alloys is commonly 16-64 microinch Ra.
Anodizing (Type II Or Type III) Aluminum is typically anodized. Type II anodizing creates a corrosion-resistant oxide finish. Parts can be anodized in different colors—clear, black, red and gold are most common. Type III is a thicker finish and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II. Anodized coatings are not electrically conductive.
Powder Coating All die cast parts can be powder coated. This is a process where powdered paint is electrostatically sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard wet painting methods. A wide variety of colors are available to create the desired aesthetic.
Wet Painting All die cast parts can be wet painted in a wide variety of paint formulations and colors.
Plating Zinc and magnesium parts can be plated with electroless nickel, nickel, brass, tin, chrome, chromate, Teflon, silver and gold.
Chemical Film A chromate conversion coat can be applied to protect aluminum and magnesium from corrosion and improve the adhesion of paints and primers. Chemical film conversion coatings are electrically conductive.
