3D printing has a unique advantage in product concept design, prototyping, product review, and functional verification. We could manufacture prototype from CAD digital model directly by SLA, with fast processing speed, short production cycle, no need for cutting equipment and vowin
s. Besides, we it could machine prototypes and vowin
s with the complex structural shapes or being difficult to form by the traditional methods, and the finished prototypes and molds have high precision. 3D printing is applied in the various field, and it could be customized for small batch production.
2. RIM:Reaction Injection Moulding
RIM technology produce parts by the simple molds, such as aluminum molds, resin molds, and ABS
molds. Resin molds are used more commonly, because resin molds are lower cost and the resin molds are manufactured faster compared with the aluminum. RIM technology is suitable for the small batch trial production pf the product development process, which is used in the automotive industry, medical products and instrumental housings, car bumper, car hood, etc. All in all, RIM technology could manufacture small batch production parts with the large and simple structure, and the plastic parts with the uneven thickness.
The vacuum casting technology uses the prototype of the product to make silicone molds under vacuum status, and adopts materials such as PU, ABS etc. to manufacture parts under vacuum status which is the same as with the prototype of the product. This method is suitable for small batch production especially . It is a low-cost solution to solve experim
ental production and small batch production during the short time, and it also could meet the functional test of some engineering samples with complicated structure . All in all, the vacuum casting technology is suitable for the simple test and the needs of the conceptual design.
