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 Machining
Aluminum Machining
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 machining
Magnesium machining
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
Zinc Machining
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.
Aluminum Sheet Metal Bending
Aluminum Sheet Metal Bending
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
Steel Sheet Metal Bending
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 Metal Bending
Copper Sheet 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 Die casting
Aluminum Die casting
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 Die Casting
Zinc Die Casting
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 die Casting
Magnesium die Casting
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.

FAQ

Does Sanwo rapid manufacturing company provide design service?


No, we don’t do design, we only provide the technical support for prototyping and manufacturing services when client already have the 3D and 2D file which needs design verification or production. We can provide the suggestion and solution for the friendly machining or manufacturing drawing needs after review upon your orders.


Is it possible to get a quote from the picture?


Not able to quote according to the picture, will need to know the part size, finish detail, functional design internal and external, size of the under-cut, Radius, and holes.


Can I make the product if I only have the part sample at hand?


If for simple shells product, yes, we can do 3D scanning to get the file for prototyping and samples, or using vacuum casting for the products copy. This will depend on the part detail, size and parts status provide. But it will be better to get the 3D file to avoid the functional and dimension different.


what type of design file format does Sanwo rapid made company prefer?


For RFQ, 3D file in STEP/STP, X_T, IGS, STL, will be fine. 2D drawing will prefer the PDF with the material required, tolerance and main dimensions. For both prototyping and production we will prefer STEP file and 2D drawing in PDF with details.


what kind of design will be CNC machined friendly and cheaper?


For functional prototype, if has no impact on the assembly, radius on edge, on root of rib and corners will be bigger the faster. Especially on metal parts which will require EDM to do the radius clean, cost and lead time raise. For appearance parts, split and bond if acceptable, will be faster and cheaper


How can I make sure my design is under confidential?


We are doing business around the world providing supports for those designers in research and development department, and for end clients the production manufacturing. We totally understand the important for their unpublished product confidential, we keep confidential for everyone so that our business can last long, and we accept all kind of NDA signed and seal.


what is the expected delivery normally?


For prototype parts, if without post-finish can finish around 10 days, and if with post-finish will need around 14 days. For rapid tooling, mold time around 25 days and production time7-10 days.


Is Sanwo the delivery lead time working day or calendar day?


It is the working days 6 days a week excluding Sunday for prototyping, and it is the calendar day for injection molding. For all shipping date will avoid Sundays as Sunday has no shipping express working.
