For the above customer's detail demand, the size of the whole motor is larger than 100mm or more. At present, we don't have the same mold with the up requirement, there are about 30 parts of the whole motor, and about 10 main parts, all of them need to open the mold. In order to help our customers to save the cost, our engineers optimize the design of the internal motor rotor and stator structure, without changing the outer diameter and power speed of the motor, combined with our existing parts size, we only open the mold of the plastic shell, and keep the mold cost to USD30,000. Our engineers optimized the design of the internal motor rotor and stator structure, without changing the outer diameter and power speed of the motor, combined with our existing parts size, only the mold of the plastic housing was opened, and the cost of the mold was controlled to about USD 10,000; as some raw materials can be used, the price of the product was reduced very well; we not only helped the customer save the mold cost, but also reduced the price of the motor on the original basis; the customer was very satisfied with our solution!
