Product description
This rotor stamping mold is a modern tool, which integrates multiple functions such as material movement, cutting, tapping, stacking, etc. to achieve full automatic continuous production. It is a key die for the production of automobile motors, and is also one of the most precise stamping mold in modern industrial production.
The key parts of this mold are making of SDK11 metal, and after 60-62 vacuum hardening treatment, it can guarantee a long service life in high-speed production. We guarantee that the stamping mold can be punching for 20000000 consecutive times without maintenance.
Due to its fast production speed and minimal material waste, this mold is highly suitable for factories producing motors on a large scale.
Advantages of rotor stamping mold
Fully automatic stacking
It can automatically stack iron materials according to the height of the rotor, without any manual intervention. Engineers can also easily change the required height of the rotor by setting up stamping machines. This means that this mold can produce motor rotors of different heights, meeting the diversified needs of the market.
Highly automated production
This is a highly automatic production tool with multiple built-in pressing modules for different functions, such as cutting materials Pressing molding, bending materials, etc., it can run smoothly in high-speed production at 280 times per minute.
Super saving raw materials
This rotor stamping mold is designed for automobile motors. It can produce the rotor and stator of the motor at the same time. Two workstations run at the same time. It has almost no wasted raw materials.
Developing precision manufacturing technology
Due to the fact that this mold needs to be uses in a high-speed production environment, each part of it needs to be manufacture through high-precision technology, so it can ensure that the tolerance range of the rotor is control within 0.01mm.
Advanced functions of rotor stamping molds
With the development of industry, the manufacturing technology of motors is constantly innovating. As the speed of motors increases, there are higher requirements for the concentricity and balance of rotors. In order to meet these stringent requirements, some copper wire slots of rotors are spiral shaped.
To produce this spiral shaped rotor, we must install a servo motor on the side of the mold. When the rotor stamping die completes a push, the servo motor will rotate the iron core by a small angle, and finally turn the rotor into a spiral shape.
This type of mold with a servo motor usually has a control cabinet and touch screen to control the rotation angle of the servo motor. The price of this mold is slightly higher than that of ordinary molds.
If you are looking for a stamping mold for rotor and stator, we can provide a good solution. You can contact our engineers for more details.

Design Difficulties of Rotor stamping mold
Due to the thickness of steel sheet materials typically ranging from 0.2-0.8mm, this kind of elasticity is relatively large, and we need to fully consider the impact of its elasticity on the size.
This mold is with multiple independent modules, and the dimensional error of material movement must be control within 0.01mm, which places high demands on the manufacturing process of the mold.
The layout of the mold core is also a crucial element, and the utilization rate of materials needs to be fully considered, otherwise a large amount of steel sheet materials will be wasted.
The mold for the skewed rotor requires the installation of servo motors, which must be modeled and designed using 3D software to generate precise assembly structures and avoid part interference and dimensional errors.
The cutting edge of the mold must undergo high-temperature hardening and annealing treatment to ensure the service life of the parts.
The mold closing needs to follow the positioning block. Even if the stamping machine is overloaded, the mold will not be easily damaged.
Application of Rotor stamping mold
Our professional field is to manufacture stamping mold for rotors and stators of motors used in automobiles, such as wiper motors, window lifter motors, brake pump motors of battery cars, etc., but we can also manufacture dies for motors of household appliances, such as coffee machines, vacuum cleaners, hair dryers, air pumps, massage machines, etc.
Due to the small size of the stamping machine used for testing the mold, we are currently unable to manufacture large-sized rotor molds, such as rotors with an outer diameter greater than 200mm. If you require rotors with an outer diameter greater than 200mm, unfortunately, our molds may not be able to meet your requirements.
