What Is Rapid Prototyping?
Rapid prototyping involves specialized manufacturing techniques for making high-quality physical models of a 3D design idea. Prototypes are useful for design improvement, as stepping stones to full production or for engineering testing. They are meant to be quick and economical, without the need for the investment in hard tooling. Many of our clients need to produce a physical part quickly in order to validate a design or to capture a fleeting sales opportunity.

Advantages Of Making A Prototype
How can making a prototype help you and your business? Here are just some of the ways:

• Show your customers and investors a physical model of your product
• Demonstrate the appearance, dimensions and features of your product
• Test the market with your product before production
• Save time and money by identifying and reducing design flaws
• Improve and streamline the production process
• Create multiple versions with different colors, surface textures and finishing processes

CNC Machining
We can offer fast turn-around, multi-axis, high-speed CNC machining solutions to fulfil most requirements for concept models, prototype parts and low-volume production components. We are able to machine directly from your 3D model and can supply parts from one-off’s prototype to low-volume production quantities in a wide variety of materials, including plastics and metal.
Plastics: ABS, PC, POM, PP, PMMA, PBT, PTFE, Nylon, Nylon+30%GF, PEEK and PVC.
Metal: Aluminum, Zinc, Magnesium, Brass, copper, Bronze, Mild steel and Stainless Steel etc.
We can also supply surface treatment methods, such as painting, silk screening, polishing, sand blasting, anodizing, power coating, plating, passivation, laser etching, knurling etc.

Metal 3D Printing
Metal 3D printing is ideal for making complex shapes that combine light weight with high strength. You don’t need to invest in hard tooling and parts can be printed in hours rather than days or weeks. You can add complex internal features which can’t be made using traditional milling-turned machining .

We have expert technicians in-house who provide you with an unparalleled degree of engineering expertise to ensure you get the highest quality finished product. Find out more about our 3D metal printing service.

Vacuum Casting
Vacuum casting (cast urethanes) is a commonly used rapid prototyping technology, when low volume of a 3D CAD model are required. The parts are made out of Polyurethane which has properties close to real injected plastics, such as ABS, PC, PA, POM, PA, PP or TPR rubbers etc. Usually, a series of 5-100 pieces will be run using this casting technology. Each Silicone mould can make a maximum of 20 to 25 pieces.

Not only will you benefit from our exceptional attention to detail, but we also provide a full suite of finishing services to bring your part up to showroom quality. Learn more about what our vacuum casting service can do for you.

SLA
“Stereolithographic Apparatus”(SLA) is an additive manufacturing process using a vat of liquid resin and a UV laser to build prototypes a layer at a time.The laser is used to trace out and cure a cross-section of the part design on the surface of the liquid resin and the process is repeated. Each newly cured layer adheres to the layer below it.

SLA is one of the earliest 3D printing or additive manufacturing processes for plastic. Not only are these techniques fast, but they allow you to produce complex internal features impossible to make with traditional manufacturing. We use SLA to make master patterns for vacuum casting molds.

SLA is ideal for making small volumes of finished parts or prototypes. If you need larger quantities, try one of our low volume manufacturing services.

Prototyping To Production
At SINO MFG, we also offer low-volume production services where we can provide you with 100,000+ plastic and metal parts. Our low-volume manufacturing options ensure that we can take you through the entire journey from prototype to bridge tooling to low-volume production.
