Zinc Plating 2.0mm Wire Forming Special Springs

Metal Spring Bending Clip Special-shaped Springs Wire Forming Spring Special Shape Spring

The difference between the special-shaped spring and the conventional spring is that the spring itself is irregular, with curved and a large number of complicated angle designs. Suitable for some special occasions.

Types of special-shaped springs special-shaped springs special-shaped compression springs special-shaped torsion springs special-shaped leaf springs special-shaped circlips

There are many types of special-shaped springs, which are introduced below:

(1) Reducing helical spring: It is used in some special occasions. The material of the reducing spring is generally circular cross-section material, and most of them bear compression load.
(2) Leaf spring: The material of this spring is the spring strip (or plate), which is processed by special molds on special equipment or general pressure processing machine tools. Leaf springs, wave springs, and light springs have thinner materials, while medium or large disc springs often have thicker materials. These springs are also widely used.
(3) When the installation space is limited, a spring with a rectangular cross-section material is often used. A spring made with a rectangular cross-section material can obtain a larger load under the same space and the same amount of deformation. Compared with a spring with a circular cross-section material, this type of spring has a larger cross-sectional area in the same space, so it absorbs more energy, as shown in the figure below. It can be used for heavy machinery, stamping dies or particularly rigid springs

Custom Special-shaped Springs

Special-shaped Springs forming machine

Due to the ever-changing variety and shape of springs, it is required that the spring machinery can meet the requirements of convenient adjustment and suitable for multiple varieties. The new profiled spring forming machine has been able to complete a series of complex actions from wire feeding to coil springs and bending, and finally can also perform hook and loop processing of the spring tail. It can not only make compression springs, but also can easily produce tension springs, torsion springs, double-headed torsion springs, double-layer springs, and various types of springs.

What is the difference between 302 and 304 stainless steel springs.
304 stainless steel spring 302 stainless steel spring stainless steel spring production
What is the difference between 302 and 304 stainless steel springs?
First of all, we can see from the element table that the carbon content of 302 stainless steel is C≤0.15, and not all 304 stainless steels are suitable for making springs. Generally, 304H is used to make springs. The carbon content of 304H is 0.04-0.1%. In between, we can see through comparison that the carbon content of 302 stainless steel is higher than 304H, and the increase in carbon content increases the elasticity of the stainless steel spring after it is produced.
Therefore, under the condition that the specifications of the two models are the same and the production process is equivalent, the spring force of the 302 stainless steel material must be slightly greater than the 304H stainless steel spring. In other properties, there is almost no difference.
302 stainless steel springs rarely appear in the domestic market, but 302 stainless steel is widely used abroad. Why? This is because 304 stainless steel is recognized in the country and used more, and 302 stainless steel can basically be replaced by 304. There are infinite specifications of spring steel wire. The steel wire is slowly cold drawn from a thicker steel rod to become thinner, because the 302 material itself is less used, and the cost of cold drawing is higher. Therefore, general 302 stainless steel is cheaper than 304 stainless steel, but 302 stainless steel wire is more expensive than 304 stainless steel wire. At least this is the case in China.
So why is there still a demand for 302 stainless steel springs under such conditions? In fact, many reasons come from the fact that most foreign products use 302 stainless steel, and many domestic products are also following suit. If you directly change to 304, the force value of the spring will change, and redesigning and testing a new spring is What a waste of manpower and material resources.

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.
