As a professional spray painting master, sanding is an essential part of the entire process. Knowing the correct sanding techniques and skills plays an important role in enhancing the gloss, smoothness, and adhesion of the coating surface, greatly improving the appearance of spray painting products. This article will introduce how to choose suitable sanding materials, master the correct sanding techniques, and related knowledge of attention points, methods, and sanding functions.

Low-pressure injection molding, also known as Reaction Injection Molding (RIM), is a new manufacturing technology widely used in the rapid production of injection-molded parts. It uses a two-component polyurethane material that is mixed and then injected into a quick mold at low pressure and room temperature, forming a product through chemical and physical processes such as polymerization, cross-linking, and solidification. Low-pressure injection molding has the advantages of high efficiency, short production cycle, simple process, and low cost. It is suitable for small-batch tryouts in product development, as well as small-batch production of relatively simple structural parts and large thick-walled or uneven thickness products.

Industrial design is a key link in the product development process, and the design stage is an important stage in determining product costs. In the industrial design process, prototype production is a very important part, involving various aspects such as previewing product needs, orienting design, controlling costs, and conducting market research. How to provide high-quality services in prototype production, improve production efficiency, and grasp cost control points has become a topic of discussion among production companies.

In modern society, hardware products are widely used in various industries. However, the wear resistance and corrosion resistance of hardware product's surface have always been an issue. Traditional electroplating can solve this problem, but it also causes pollution to human health and the environment.

In the field of machining, CNC technology has a wide range of applications in prototype machining. Before processing the prototype, the primary task is to make a sample. The traditional manual making process is complex, with long cycles, high costs, and is easily affected by human factors, resulting in a decrease in processing efficiency and quality. The application of CNC machining technology can effectively solve this problem, and the advantages of CNC machining are well reflected in the all-round automated machining of prototyping.
