We can offer fast turn-around, multi-axis, high-speed CNC vowin.cn/en/News/news1251.html' target='_blank'>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, p to low-volume production quantities in
a wide variety of materials, including plastics and metal.
We can also supply surface treatment methods, such as painting, silk screening, pad printing, polishing,
sand blasting, anodizing, power coating, plating, passivation, laser etching and knurling etc.
Vacuum casting (cast urethanes) is a commonly used rapid prototypes 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, TPE's 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. Learn more about our vacuum casting service.
3D Printing (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 was the first ‘rapid prototyping’ technology. These parts can, however,be brittle
and weak, so they have to be carefully handled.
General speaking, lots of parts with complex structure can be 3D printed, it not only has a beautiful appearance, but also prints quickly, which can greatly improve work efficiency.
However, considering the issue of cost, large-scale prototypes will not use 3d printing, but will still use traditional CNC Machining. Like a car bumper, it is bulky, and the cost is slightly lower if use CNC Machining. But the cost is higher, and the strength performance is not as good as CNC Machining.
3D Printing is suitable for products with relatively small volume, which are generally electronic products. It has a complex structure and light weight, fast printing time, good quality, and can print easily.
Therefore, it is very important to choose the appropriate process when making parts. For larger products, we still prefer to use traditional CNC Machining, and then some more complex and small products choose 3d Printing will be more suitable.
