How to order

1.Pls send me your drawing or sample

2.We offer you our best price

3.After you confirmed the price,we start to prepare the sample(usually within one week)

4.After you confirmed the sample,you place an order

We import the most sophisticated computer compression spring machine from Taiwan; it can

do 100 percent inspection to spring length, which ensured the spring quality stable and precise.

Q:Is spring steel manganese steel?: Spring steel is not manganese steel, there are many kinds of spring steel, manganese 65 is more commonly used spring steel, as well as carbon spring steel and alloy spring steel.Manganese steel refers to the high manganese content of carbon steel structural steel.

Q:What kind of spring has the best performance?: Spring outside diameter, the same spring at both ends of the outer diameter and the middle of the outer diameter is not the same, unlike the spring, the force has a slight impact. The same batch is very different from each other, indicating that the machining accuracy is very poor.

Q:The glass door spring is generally guaranteed for several years: Quality and price are pretty much the same. Many other miscellaneous brands of spring can be guaranteed for five years, three years it is best to begin with a reliable brand

Q:Buffer spring buffer for automobile: The automobile spring buffer adopts the cushion principle to reduce the vibration produced by the vehicle during the running, and increase the comfort of the car. When the vehicle is equipped with a spring buffer, the problem of the spring of the shock absorber is effectively solved, the performance of the shock absorber is recovered, and the shock absorber and the suspension system are also protected, and the oil seal of the damping core is avoided. As long as the quality is good and the car to pick their own spring buffer models, can save at least 3 sets of shock absorber overhead, and a shock absorber to several hundred dollars or a thousand dollars, the long term of the owner is indeed a big burden. The new car spring buffer is a buffer of urethane material, not only simple and easy installation, no looseness of vehicle any screws, can make the body up 3 5cm, recovery of the original body height, improve the stability of road safety through deceleration and brake, greatly reduce the fatigue feeling after. The car cushion on the market are made of urethane material, suggest that you choose the buffer glue to the regular manufacturers purchase, on the market there are many inferior or three villages are often unable to get some of the results, some even hurt the shock absorber, shorten the service life of the damping rubber. My friend used Jinke rubber buffer for years should be full, very good quality.

Q:What is spring pressure and height?: Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter

Q:What's the spring material to?: There are many kinds of spring steel, the most commonly used are 65Mn and 60Si2Mn.

Q:How to choose spring steel material?: Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties

Q:Cold rolled coil spring spring and difference ": The main production process is different, the compression spring as an example:The typical process of coil spring: blanking - end processing (rolled or forged flat) - heating - - - quenching - tempering spring roll grinding end - compressor (load - Test), shot peening (cleaning) - coating.Cold roll spring does not require heat treatment of material roll, point line process: rolling, annealing, stress to both ends of the surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Coil spring is mainly used for rolling large spring, heating easily after twisting forming, springback is smaller, molding after quenching and tempering treatment.The cold coiling spring is directly coiled with spring steel wire, and the resilience is greater, and the winding tools need to consider the springback compensation amount and roll into the direct tempering process.

Q:What is flat steel? Plain carbon flat steel? Spring flat steel: Flat steel, also called flat steel strip, is a long thin steel with a rectangular cross-section. According to the production process, it can be divided into hot rolled flat steel strip, fine shearing flat steel belt and cold drawn flat steel belt.Ordinary carbon flat steel - the component is ordinary carbon structural steel, suitable for wide range.Flat spring - flat steel used for making spring plates of automobiles, containing manganese.

Q:What kind of material does spring have?: In some specific occasions, such as pH and humidity, we often use stainless steel to make springs.The material of the die spring is usually made of chrome alloy steel. Chromium alloy spring steel has the characteristics of high temperature resistance, great rigidity and long service life.
