Stainless Steel Small Tension Coil Spring High Quality Extension Spring Manufacturer
A compression spring is a helical spring that provides a force as the spring is compressed. Compression springs have several types of shapes including conical, barrel, hourglass, and the most common type of all, cylindrical. Compression springs are available with or without a grind on the ends. Compression spring with a grind will stand more square than a spring without a grind. Springs with square, ground ends will have a lower solid height than a spring with no grind.

Application of compression springs
Aviation, automotive, motorbike, bicycle, automatic equipment, household appliance, medical device ,toy, telecommunication, computer, instrument and meter, furniture, electric tools, mold and other industries.
Spring surface treatment method
The spring surface can generally be treated, such as blackening (blue), phosphating, electroplating, spraying, zinc chromium film Dacromet, etc. Dacromet protective layer has excellent corrosion resistance, which is 7-10 times that of traditional electroplating layer, and there is no hydrogen embrittlement of electroplating process. And strong adhesion, especially suitable for surface protection of elastic materials.
The surface of Dacromet treated products is silvery white. The main characteristics and use of surface treatment, corrosion resistance, oxidation treatment, black, blue, commonly used spring protection is generally maintained in the air for 3 months, electroplating is used for higher protection in general air medium protection for 3 months to 2 years, phosphorus The anti-embroidery ability of chemical treatment is higher than that of oxidation treatment. It can withstand high temperature of 400℃. Generally used for the protection of important parts, or as the pre-treatment of other protective layers. Non-metallic protective layer, paint, spray paint, electrophoretic paint, etc. have strong anti-corrosion ability. It has a wide surface, especially electrophoretic paint. It is currently used in the pretreatment of automobile surfaces. Special anti-rust oil protection is often used in refrigerator compressor springs without hydrogen embrittlement. The process is simple, environmentally friendly and pollution-free.
Compression of the mold spring
The purpose of the mold spring is to remove and press the material, and the strength of the spring is related to whether the mold production is smooth, and the product is qualified. If the spring force is small, it may cause various problems such as deformation of the product, the mold does not fall out, the product cannot be taken out of the mold, the material is stripped, the knife edge, the punch is easy to wear and so on.
Mold springs are produced according to different production times. The larger the compression amount, the shorter the spring life and the shorter the mold life. Of course, the spring can be replaced if it is broken, but the specifications of each spring are different and have been determined during the design. Do not easily replace each other when in use. The spring may be weak after the mold is produced for a period of time, and the spring of lower quality may break in the mold.
Generally, the compression of the mold spring is calculated according to 300,000 times. That is to say, the spring may be weak after the mold is hit 300,000 times. Of course, the life of the general stamping die is not so long. It can also be calculated by the amount of compression. When calculating, it can only ensure that the spring is not crushed in the mold. The mold is pressed to death, which is also good for the flatness of the product.

How to choose a spring manufacturer? We can judge by inspecting the following 10 points of spring manufacturers:
1. Types of springs that can be produced.
Different types of springs require different production equipment. The more types that can be produced, the more complete the production equipment of the company.
2. Ask about the production accuracy of the spring.
The precision of producing springs represents the production technology capability of the spring factory. The higher the production precision, the more attention the spring factory pays to the quality of the products.
3. Whether there is a research and development team.
The R&D team is indispensable for an enterprise. The R&D team of the spring factory can make this enterprise develop in the direction of new processes and new technologies. ~Innovative ability
4. Whether the production equipment is imported.
Most of the domestic spring equipment is used to produce some non-important parts of the spring, the overall production accuracy is low, and there is a certain gap in product consistency. The higher the precision of the spring equipment, the higher the precision of the spring can be made.
5. Output of spring production.
The production output of springs represents the production capacity of this enterprise. The greater the production capacity, the stronger the supply capacity and the stronger the relative delivery guarantee.
6. Which manufacturers are the suppliers for?
As the saying goes, to marry a wife, you must choose the right person, and you also need to find a partner. For example, you are in the automotive industry, and Xinxiang Huispring Spring Co., Ltd. is a spring for the automotive industry. They directly supply the German Bosch company, so the product quality must be very guaranteed. This is very suitable for you. If you are making a ballpoint pen and you want an ordinary ballpoint pen spring, then this bright spring spring may not be suitable for you. You should choose an ordinary spring factory.
7. Whether there is a special testing department and whether the testing equipment is complete.
The inspection department is a necessary department of the spring enterprise. If no one supervises quality control, or quality control cannot use effective equipment for inspection, then no one would dare to use such products.
8. What is the defective rate of the spring produced? ,
The defective rate of springs of qualified spring manufacturers is generally between 5 and 12 parts per million. This data contains the data of nonconforming products detected by the manufacturer. The smaller the data, the stronger the accuracy and consistency of spring production.
9. Where are the raw materials of the springs purchased and whether they are inspected plate by plate.
The production process of the spring is very important, and the raw material of the spring is more important. For the same material, some material dealers sell it for 5 yuan, and some material dealers sell it for 10 yuan. Why is this? On the one hand, it is the consistency of the steel wire, such as some places where it is thick and some places, on the other hand, whether the composition of the spring material is evenly distributed and whether the content is qualified. The spring produced by unqualified spring raw materials is also unqualified, such as frequent breakage or deformation, and the spring load cannot be reached.
10. Whether it has the qualification certificate of the relevant industry.
For the spring industry, are some certificates very difficult to obtain, such as IATF16949 and GJB 9001C. These are very rare certificates. If this spring company has these qualifications, at least it proves to be very formal.
Finally, we still have to conduct on-site inspections and see how much the registered capital of this spring factory is, so as to avoid subsequent supply problems.
