Turn your design real product

CNC Machining
multi-axis, high-speed CNC machining meets most of the required prototype parts and low volume production components. Your parts will achieve tighter tolerances with a smooth surface.
It can process a variety of materials, including plastic (ABS, acrylic, PP, PC, POM, nylon, bakelite, etc) and matels (aluminum, aluminum Magnesium alloy, aluminum zinc alloy, copper, steel, iron, etc).
Tens of CNC mills, lathes and EDM machines ensure we manufacture all your parts on time without investing in expensive tooling. Find out more about our CNC machining service.
Vacuum Casting
Polyurethane vacuum casting is used to create a duplicate of your master pattern. ABS, PVC, PU, silicone, and transparent ABS and other engineering plastics all available for prototype parts.
The strength and hardness of vacuum-cast prototypes are lower than those of CNC components. The PU material is relatively brittle, with low toughness and high-temperature resistance. ABS provides better strength, plasticity, and post-processing capabilities. The vacuum casting hand parts can only resist a high temperature of about 60 degrees.
We have rich experience in making high-quality cast copies of master patterns. As well, we offer a wide range of finishing services. Find out more about what our vacuum casting service can do for you.


3D Printing (SLA and SLS)
SLA (Stereo Lithography) and SLS (Selective Laser Sintering) are two types of 3D printing manufacturing technology to create plastic models, functional prototypes. These processes are rapid and allow you to create sophisticated internal features that would be impossible to achieve using traditional manufacturing techniques. SLA is ideal for making small volumes of prototypes, and we use SLA to make master patterns for vacuum casting models.
Parts made of 3D printing are inadequate in strength and is easily broken, and are likely to deform in high-temperature.
Sheet Metal Prototyping
Sheet metal fabrication is the process of forming a piece of metal sheet into a desired shape through bending, stretching, and removal of material.
Sheet metal parts are known for their durability, which makes them great for end-use applications (e.g. chassis).
Due to high initial setup and material costs, parts used for low volume prototypes and high volume production runs are the most cost-effective.

Prototyping Materials

Plastics
A plastic prototype made by 3D printing, urethane casting, or CNC machining is the most common and economic way to review the appearance and function of your design

Metals
Metal prototypes and parts are typically created through CNC machining, sheet metal fabrication, or die casting. Common metals include aluminum, magnesium, steel, brass, copper, etc
Applications of Rapid Prototyping
Making a prototype of the car, test the appearance and structure. Common parts include: Headlights, Dashboard, Bumpe,Interior parts, Engine Parts, Engine Covers etc.

Electronic Product
A plastic prototype made by 3D printing, urethane casting, or CNC machining is the most common and economic way to review the appearance and function of your design
Rapid prototyping is widely used to produce implants, monitoring systems, and many other medical device prototypes. It also useful in craniocerebral surgery, neurosurgery, oral surgery, plastic surgery, and head and neck surgery to help surgeons in surgical planning.

Fashion and Artwork
Metal prototypes and parts are usually made by CNC machining, sheet metal fabrication, or a casting process. Common metals include aluminum, magnesium, steel, brass, copper, etc
Benefits of Rapid Prototyping
- Demonstrate the product's functionality and appearance.
- Show a physical model of your product to your customers and investors.
- Before going into production, test the market for your product.
- Identify and eliminate design defects to save time and money.
- Streamline and improve the manufacturing process
