Kunshan Tongmao Electronics Co. , Ltd. . Deep Ploughing Voice Coil Motor R & D, intelligent and sales for more than 10 years, now Tongmao made a variety of voice coil motor products are widely used in all walks of life, can achieve the same product import substitution, by equipment manufacturers and inspection and testing institutions, colleges and universities alike. 

        Is the so-called“Gold Cup silver cup as the people's Word of mouth”, with Mao manufacturing voice coil motor is favored by consumers because of its high quality, then how to distinguish the quality of voice coil motor good or bad? Share some TIPS. 

       1.Appearance quality surface treatment: surface treatment is an important reflection of the appearance quality of voice coil motor, high-quality surface treatment not only has a beautiful effect, it can also improve the wear resistance, corrosion resistance and oxidation resistance of the product. Common surface treatment methods are anodic oxidation, electroplating, spraying and so on. Chamfer symmetry: Chamfer refers to the edge of the metal workpiece or around the hole, with a specific angle to remove the corner, so that it is beveled. The main role of chamfering is to prevent cutting, scratching, wear and other phenomena, improve product life. The chamfering symmetry means that the chamfering shape and size of each edge are consistent, which is very important for the quality of voice coil motor. No surface defects: high quality voice coil motor in the production process, should be strictly controlled surface defects. For example, the product surface can not have scratches, bubbles, dimples and other phenomena, to ensure that the voice coil motor appearance quality to achieve the best state.

       2.The uniformity of winding density of voice coil motor directly affects the performance of products. With Mau winding personnel have a wealth of winding experience, and have advanced winding machine support, can achieve a neat and error-free winding coil. 

          3. Magnet quality magnet is an important part of voice coil motor, Tongmao selected magnets are from well-known domestic magnet suppliers.
