New Production way for Yacht Model ----------3D printing   Before 3D printing , Many yacht model is done by CNC or vacuum molding, it need more time and cost. Now, 3D printing can make it easily and less cost . Advantage of 3D Printing technology : 1.Can manufacture objects with complex shapes and structures, including internal structures and hollow parts 2.Can customization and personalized design based on needs 3.Can save materials adn reduce waste that only necessary materials are used to manufacture objects 4.Can shorten the product development cycle, allowing for rapid prototyping or small- scale production 5.Can quickly respond to design changed and can be reprinted after modifying the digital model 6. Digital manufacturing can be carried out without need for molds and fixtures.            

Plastic products are widely used in the national economy and people's daily lives. They have become good alternative materials in industries because of excellent characteristics. Injection molding is the most effective method in the methods of plastic molding. In the process of injection molding, uneven cooling is one of the main factors that lead to various defects. To ensuring the quality of plastic products, mold temperature is needed to be controlled strictly. The general way to control mold temperature is machining cooling channels in injection mold. Due to limitations of conventional machining process, traditional cooling channel (TCC) is formed form straight line drilled holes. When the structure of plastic part is relatively complicated, the distance between channel and cavity will vary with the different location, thus results in non-uniform cooling. In order to control mold temperature fast and accurately, the concept of conformal cooling channel (CCC) was proposed. Cooling channels contour to the cavity surface that is called CCC. Injection mold with CCC can enhance the productivity of plastic part and bring significant economic benefits. In general, the key scientific issues related to applications of CCC include: 1) designing of conformal cooling channel; 2) how to evaluate the cooling effect of different cooling system, select cooling system project; 3) how to manufacture injection mold with conformal cooling channels.

CAV(Computer Aided Verificationthe computer) is to superimpose and compare the 3D data obtained from the 3D shape of the tested workpiece after high-precision scanning with the original designed CAD drawings. Obtain the color deviation map of the whole part, so as to quickly and intuitively judge the dimensional error and deformation of the tested workpiece and the CAD drawings.  CAV technology is more and more widely used in sheet metal, injection molding, die casting mold, turbine blades and other industrial fields   Advantage of CAV >>Fast and high-precision acquisition of real 3D data of the tested parts(highest accuracy of 0.003mm) >>CAV can Intuitively, Efficiently and Quantitatively evaluate the geometric Defects, Shape Deviation and Warpage of the part appearance
