When making a SITC transporter model, in order to achieve the smoothness and precision of the body lines, a series of delicate and complex process steps are involved.
First, in-depth prototype research is the foundation. The production team needs to conduct a comprehensive analysis of the real SITC transporter. Not only through field observation and multi-angle shooting to record the direction of every line of the body, but also to accurately measure the curvature, length, width and other data of key parts to provide accurate reference for subsequent model construction and ensure the high similarity between the model and the prototype.
Second, professional design software is used. Using software such as CAD (computer-aided design) and Rhino, the collected body data is digitized and the model outline is carefully outlined in a virtual environment. Designers use the curve tools and surface modeling functions in the software to repeatedly adjust the body lines to make them smooth and smooth, preview and optimize possible line defects in advance, and achieve ideal visual effects.
Third, select suitable production materials. For the main body of the body, plastic sheets or alloy materials with uniform texture and strong plasticity are often used. Plastic sheets can be shaped into complex shapes through heating, vacuum forming and other processes, while alloy materials can ensure the stability of the body structure with their strength advantages. Both can accurately present the body lines and avoid the defects of the materials themselves affecting the accuracy of the lines.
Fourth, exquisite cutting and forming technology. The use of high-precision laser cutting technology can accurately cut materials according to the design drawings to ensure that the edges of the parts are neat and smooth, laying the foundation for subsequent splicing. In the forming process, such as the bending process of the body side panels, professional molds are used in conjunction with CNC equipment to accurately control the bending angle so that the body lines transition smoothly.
Fifth, fine grinding and polishing process. After the initial assembly of the model, the manual grinding process comes on stage. Craftsmen use sandpaper of different meshes to gradually grind the body surface from coarse to fine, eliminate splicing marks and minor flaws, and then polish it to make the body present a mirror-like smooth texture, further highlighting the smoothness of the lines.
Sixth, strict quality inspection and control. Using professional equipment such as a three-coordinate measuring machine, the key points of the model body lines are measured and compared with the design data. If the deviation exceeds the allowable range, it is immediately reworked and adjusted to ensure that each Sitc transporter model can accurately display smooth body lines.
Finally, in the assembly process, workers strictly assemble parts in accordance with the predetermined order, and make fine adjustments while assembling to ensure that the overall lines of the body are coherent and unified, perfectly presenting the charm of the SITC transporter.
