How to choose the suitable of processing methods for prototype?
It is usually necessary to think about what kind of prototype manufacturers to find and how to choose the right way of processing Before making the prototype.There are many processing methods of prototype. The CNC machining,3D printing and silicone tooling are three kind of common processing.Although all these methods can be used to make prototype that they are quite different from each other. If you do not choose the right way of processing during prototype processing. Its not only a waste of money, but alsothe results may not be very satisfactory, Here is to introduce how to choose the right way of processing?
1.CNC processing
It's done with a CNC machine. There are a wide of material for CNC processing including metal, plastic and even wood. But the other prototype processing methods will be limited by the material, For more importantly, the high precision of CNC machining prototype generally within 0.1~0.05mm, with the high surface quality of CNC prototype ,especially after of spray paint and screen printing that even more notable than the products produced by mould. Duo to the cost of CNC prototype is calculated according to the cost of materials, CNC working hours and surface treatment, it is more expensive to process small and complex with CNC, The methods of SLA is generally adopted for such prototype .
2. 3D printing
The principle of discrete or stacked forming is adopted. It simplifies a very complex three-dimensional manufacturing process into a superposition of two-dimensional processes which can be used to process any complex shape parts.The more complex the partsthe more it can show the superiority of 3d printing technology. However, this processing method is charged by weight, so it is not cost-effective to use 3d printing for larger prototype and the size of 3d printing is also limited.
3. Silicone tooling:
Make a set of silicone mold first, and then pour liquid into the mold, Take out it when liquid cooling. The advantages of silicone tooling are fast time, less cost, small failure rate for processing.One silicone mold can make about 10-15 pieces of product, The materials for methods of Silicone tooling can be made by ABS, PC, PP, PA, soft rubber, transparent prototype .etc.
The processing characteristics of CNC machining, 3D printing and Silicone tooling of several prototype manufacturing methods are introduced respectively. Believe that you understand these, will be able to choose to do the most suitable method processing for prototype.
Duochuang prototype focus on rapid prototyping for six years. specializes in CNC machining ,3Dprinting, Silicone tooling. Vacuum casting. Small batch production etc.
