Springs can be manufactured in different materials and surface finish depending on factors such as application or project requirements and operating environment.  While the materials and surface finish are very important to the function of the springs.   Here below are the materials option and its characteristic for your review to make the right decision for your application.   High-carbon Steel: Economical ,strong, versatile and easy to use. While it could not work in temperatures over 250°F and it is not suitable for applications requiring long life   Alloy Steel: Strong and malleable engouth for applications with high impact requirements or...

Theft of small items in retail stores is a problem that occurs. An easy safe method of theft prevention is to introduce a time delay between the dispensing of multiple products. If there is a considerable delay between the dispensing of individual products, then thieves are less likely to steal the products. A shelf delay propeller equipped with variable force springs can achieve this goal. The propulsion system includes a pusher, a track and a stop mechanism. The push system includes a resistance mechanism connected to the track and the pusher, and controls the forward movement of the pusher along the...

A spring motor is a pre-tensioned steel belt that is wrapped around on a torque drum, which can be unwound onto a storage drum later. The torque drum is mounted on a shaft that rotates with the drum and is connected to drive a generator. The spring force is released at a constant angular rate, thereby making a generator to produce a constant voltage output at a constant speed. A spring motor that produces constant torque and produces the desired torque in any coil state without excessive torque when fully coiled. Incorporating a drive system for a generator, wherein the drive system includes a spring motor...

When the curtain is pulled to the top it sags and when it is pulled to the bottom it springs back a certain height.   Qianye Spring Company has succeeded in developing this cordless blinds spring. The steps in the design of a cordless curtain spring are as follows. 1. Determining the size of the winding spring force It is usually necessary to determine the weight of the curtain. It is usually possible to measure the force required to hold the cordless curtain at the top and to measure the force required to hold the cordless curtain at the bottom.   Determining...

We have been a natural partner for designers and manufacturers of electric vehicle charging stations, providing them with trouble-free cable management solutions for their electric vehicle charging stations around the world. By applying our power springs in retractable cable reels, cable wear is reduced and cables can be neatly stored away when not in use. The natural tendency of the power spring to expand imparts torque to the mandrel or case, which generates the available torque. The torque generated is cumulative, so the torque increases as the spring preloads and decreases as the spring unwinds. Torque and a total number...

The seat belt's principle is that when it is fastened, it can be stretched at will. When braking in a hurry, however, the belt is tightened, and the belt reel is the key component that plays this role. Its function is to store the webbing and lock it out, making it the most complex mechanical part of the seat belt. The part of the reel that allows the seat belt to be reeled in freely is the power spring. The spring is coiled from steel tape and is used with a spring box to limit its outer diameter. The centre...

Sonar devices that transmit sound waves have previously been used to obtain information about underwater objects, including fish, structures and obstacles as well as the bottom, for locating fish and other underwater objects. New and improved sonar imaging systems which employ mechanical scanning capable of being attached to a surface vessel, such as a fishing boat. The boat does not need to move to generate high quality photo-like 360 degree sonar images.   The system provides a deployment mechanism mounted on a beam which lowers a sonar pod (i.e., a sonar transducer assembly) into the water. In particular embodiments, the...

Commercially available roller blinds for high speed trains can be stopped in any position by the resistance of the side channels. The operation is light and the stopping position is at your disposal. Cordless roller blinds on the market will add some components (reduction devices, damping devices, gear devices, limit devices, etc.) to achieve perfect lifting, free positioning and free stopping.   In the case of cordless roller shutters, Thousand Industries has solved the problems and pain points of free positioning and free stopping in traditional lifting systems. It is because of the addition of variable force springs that the...

Clockwork toys use constant torsion springs made of stainless steel coils. An external force rewinds the spring to the output wheel (energy storage) from its natural state. When the force is removed, the spring returns to its natural state. At the same time, a constant torque (stored elasticity) is generated (released) at the output wheel, hence the term constant torque spring.   The torque is greatest when the barrel is fully wound so that the front end of the barrel needs to be output with less force. After a certain period of time, the winder, which is tightly coiled on...
