During the whole process of hand-slab processing, most of the hand-made plates undergo surface treatment through appropriate processing methods (CNC or 3D printing). The purpose of the surface treatment is to satisfy corrosion resistance, abrasion resistance, decorativeness or other SP requirements. The product features a full range of functions and there are dozens of processing techniques for the prototyping processing. As a large-scale hand-saw factory, RMT PRODUCTS CO., LTD can provide most of the surface processing requirements for manual processing, and has a standardized production process. Next, it introduces the surface treatment technologies commonly used in manual processing.
Sand blasting uses compressed air as a power source to form a high-speed jet beam (copper ore, quartz sand, corundum, iron sand, or sea sand) on the workpiece surface. Due to the impact of the abrasive on the workpiece surface and the cutting action, the workpiece surface can have a certain degree of cleanliness and different roughness, improve the mechanical properties of the surface, thereby improving the fatigue resistance of the workpiece and improving the bonding strength of the workpiece. The increase of KPARE and paint coating extends the durability of the paint film, and the flow and decoration of the paint are also beneficial.
