For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have
received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all
cases we will try to accommodate your needs. In most cases we are able to do so.

A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.

The window regulator motor is the power source of the window glass lifting system, responsible for driving the glass up and down. It is usually installed inside the car body or in the car door, connected to the window glass through steel wire ropes or guide rails, to achieve the control of the window lifting. The working principle of a motor is based on electromagnetic induction and changes in the direction of current. By changing the direction of current, the motor’s forward and reverse rotation can be controlled, thereby achieving the up or down movement of the car window. The start and stop of the motor are controlled by the switch inside the car, making it convenient for the driver to operate. In addition, in order to protect the motor, wire rope, and guide rail, a lubrication system is also installed in the system to provide lubricating oil for these components, reduce friction, and extend service life.
