At present, the company has high-end laser cutting machine, CNC machine tool, CNC bending machine, etc., with high precision and high processing efficiency. Now it only carries out simple processing. In order to better play the benefits of the equipment, it is necessary to introduce high-tech and high-value-added products. The density, strength and microstructure of iron-based materials are better than those of traditional powder stamping process by adopting unique binder formula, adding alloy elements such as Ni, Mo, etc., combined with degreasing sintering gun barrel muffler technology and metal injection molding process. At present, China's export of electric tools muffler blasting lack of competitiveness, low price, due to the material, design and technology and other reasons, the motor generally only 40% - 50% efficiency. In order to better meet the requirements of the international market for product power, only by increasing the volume of the motor, can the power of the motor be improved. This brings about the problems of large volume, heavy weight, good appearance, high cost and market competitiveness. Therefore, it is necessary to develop high-efficiency motor with electric tools as the core.
