Low volume Metal Machining
At Sanwo Metal, we provide services for all kind of Metal works in low volume to mass production. CNC machining, CNC Cutting, CNC Lathing Turn and CNC Milling Process are the most accuracy production method for low volume Metal manufacturing, from 3 Axis, 4 Axis to 5 Axis, CNC makes it all possible for complex parts and tight tolerance Parts compared to other metal production process. Metal material choice is in big range, As long as the Metal material fits with our machine capabilities, Material Like Aluminum, Zinc, Magnesium, Titanium, Stainless Steel, Brass, Copper are Common use daily.
Aluminum is the easiest machining metal material for CNC Prototyping, machining production, soft tooling and custom products, it is a very important material that makes up nearly 80% of the machining metal material.
Magnesium is a low density metal material, it is the lightest machining metal so it is widely used in consumer electronic shells, laptop frames and covers, Keronite finish is used for Magnesium oxidize prevented.
Zinc Machining material are the same as the Casting material, Material Choice are also Zamark2, Zamark3 and Zamark5 most of the time for any designs, which the mechanical properties of the material performs good.
Volume Metal Manufacturing
Sheet Metal Fabrication including Bending and Stamping is apply on those structure frames, housings, Enclosures and Shells without complex internal structure, but with simply riveting and Tapping. Sheet Metal Fabrication is under low start-up cost and fast turnaround lead time. At Sanwo Metal Sheet Material included Aluminium Sheet, Steel Sheet like SPCC, SHCC; Galvanized Sheet like SECC,SGCC and Copper Sheet, which are in fixed and even thickness. According to the functional requirement, Sheet Metal Fabrication processing methods and Material properties requires different.
Sheet metal bending is a fastest process for metal parts, Aluminium sheet metal are used for small components and low weight frames and enclosure like computer hardware, simple consumer electronic shells.
Steel Sheet Metal bending is Cheap for big steel parts like the big machine cabins, enclosure covers, as well as the weigh supports, there are many kind of Steels in excellent performance for metal bending.
Copper sheet bending is used for the conducting electricity function required parts, due to the good material properties, Cooper sheet metal bending is widely used in Electronic industrial.
Mass production Metal Casting
Sanwo Metal mass production services for Final product manufacturing including Die Casting and Aluminum Extrusion. For Die casting, the common materials are Aluminum, Zinc and Magnesium, these materials are fusion pig metal that melting and casting in mold, and get the final product from the mold after cooling. Metal die casting to metal parts production is just like the Injection molding to Plastic parts production, are all production for final product in end use purpose.
Aluminum alloys including A380, A413, ADC10 and ADC12 are ideal strong, lightweight for complex designs, it can be high polish and texture in mold, and can apply the finish such as painting and powder coating.
Zinc alloys including the Zamak 3 and Zamak 5 are less expensive, it is ideal used for mechanical core parts and it preforms amazing mechanical properties,Zinc Alloy is good in casting status and effects great in plating finish.
Magnesium alloys including AZ31B and AZ91D are the less weight but high performance material, its is apply in applications in the Aerospace and Defence industrial. But it is a flammable and explosive material during casting.
Metal Finish Services
At Sanwo Metal, we provide all kind of post finish for Metal works, including Machined finish with CNC lines, sanding process to remove machined mark, brushing process to get hair textures, sandblasting to gain even textures, High polish to reach mirror effect, painting for appearance purpose, Plating for protecting and gloss effect, Chromate finish for anti-oxidation, Anodize, powder coating and e-coating for protecting and appearance purpose, Passivating and Bluing for rust prevention.
