Mechanical polishing mechanical polishing is by cutting the plastic deformation of the material surface is polished to remove the protrusions and get a smooth surface polishing method generally used Whetstone, wool wheel, sandpaper, mainly manual, special parts such as rotary surface you can use the turntable and other auxiliary tools, surface high quality requirements can be Superfinishing throw approach. Superfinishing throw is the use of special abrasive plastic box, in polishing liquid containing abrasive plastic box in tiles, pressed against the surface of the workpiece to be machined, for high-speed rotation. Using this technology can achieve surface roughness Ra0.008μm is the highest in the various polishing methods. Optical lens mold often use this method. Mold design is to improve the quality of mold most important step ①, select the mold material plastic box mold, in addition to outside customers for product quality to meet the requirements of Baoding plastic box, we need to take into account the cost of materials and in the intensity setting cycle, of course, depending on the type of mold, the use of work, processing speed, the main failure mode selection and other factors. ②, mold structure design, as much as possible compact, easy to operate, but also to ensure the mold parts have sufficient strength and rigidity; when the mold structure allows, corner mold parts each surface should be designed as rounded transition to avoid stress focus; ③, in the design must be reduced in the maintenance of a range of components need dismantling, especially when the replacement of wearing parts to minimize the scope of its disassembly.
