The difference in product structure, that is, the difficulty for customers to provide samples of plastic parts, can be understood as the more complex the shape of the plastic part, the more complex the Safety Needle Mould. The more difficult it is. Technically speaking, the more parting surfaces, the more assembly locations, fasteners, holes and ribs, the more difficult it is to process. The larger the ground, the longer the mold processing time. Generally speaking, the more complex the mold structure, the higher the quality of the mold. The lower the value, the more difficult it is to deal with, the more problems there will be, and the slower the product will be achieved.

Due to the magnetic adsorption during processing, long and thin sheet-shaped parts are often encountered during processing, which is difficult to process. Then, the workpiece is deformed close to the surface of the table. When the workpiece is unloaded, the workpiece will recover from deformation, and the thickness measurement is the same. However, the parallelism cannot meet the requirements. The solution can be solved by magnetic isolation grinding. When grinding, the contour blocks are cushioned under the workpiece, and the blocks on all sides are offset. Crash, processing small feed knife, more light knife, good after processing, can no longer pad the same height block, direct adsorption processing, which can improve the grinding effect to meet the requirements of parallelism. Higher requirements are put forward for high-speed processing objects of hardening data. Therefore, many machine tool manufacturers specialize in this processing. A special grinder was developed. Under the conditions of high spindle speed and high feed rate, the tool needs light cutting, but the thermal stability and thermal stability are high. Mechanical hardness is also very necessary. In this processing, high-pressure coolant is another necessary condition, but there are also some mold processing. The operator chooses the dry cutting method to avoid thermal shock to the tool. Together with dry cutting, environmental pollution can also be reduced. Most of these machines are suitable. In the processing of forging dies and small and medium-sized Needleless Injection Site molds.
