OEM Precision Metal Cnc Machining Auto Parts process:
1.Complex Geometry Die casting cantilever produces close tolerance parts that are durable and dimensionally stable.
2.Precision Die casting cantilever offers tolerances ranging from +/-0.003″ – 0.005″ per inch, and even as tight as +/- .001” depending on customer specs.
3.Strength Die cast cantilever parts are typically stronger than injection molded parts and more resistant to high temperatures. Wall thicknesses of parts can be thinner than for most other manufacturing processes.
4.Custom Finishes Die cast cantilever parts can be produced with smooth or textured surfaces and a variety of paints and plating finishes. Finishes can be chosen to protect from corrosion and improve cosmetic appearance.
Surface treatment:
1.As-Cast Zinc and zinc-aluminum cantilever 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.
2.Powder Coating All die cast cantilever 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.
3.Plating Zinc and magnesium parts can be plated with electroless nickel, nickel, brass, tin, chrome, chromate, Teflon, silver and gold.
