Compression Springs By Shape
Touhai is equipped with multiple advanced CNC wire forming machines, capable of producing compression springs of various shapes.
In addition to conventional compression springs, we also offer springs in special shapes, including conical, hourglass, square, and spherical.
No matter what shape of compression spring you need, you can find products that meet your requirements at Touhai.
This is one of the regular compression springs and is the most widely used type, being cylindrical overall.
This shape of compression spring can evenly distribute the stress it bears, preventing bending and ensuring more stable use.
Conical compression springs can be completely compressed under force to provide a longer travel distance and prevent twisting.
This type of compression spring with an hourglass shape, can evenly distribute the stress it encounters, thereby enhancing stability.
Compression Springs By End Types
-
This type of compression spring has no gap between the last coil and the adjacent one, and the ends are ground to form a flat support surface, making it more stable.
-
Compression Spring with Closed and Not Ground EndThis type of compression spring has no gap between the last coil and the adjacent coil, and the ends are not ground, resulting in a relatively lower cost and more widespread use.
-
Compression Spring with Open and Not Ground EndThis type of compression spring still maintains a gap between the last coil and the adjacent coil, and the ends are unground, resulting in lower manufacturing costs for this spring.
Compression Springs By Materials
The material of the compression spring directly affects its performance. Tuohai can provide compression springs in a variety of materials to meet the diverse needs of different customers.
-
This is a cost-effective compression spring, with a higher carbon content, offering good hardness and strength.
-
Alloy Steel Compression SpringsAdded elements such as chromium and nickel to the material enhances the mechanical properties and wear resistance of the spring.
-
Spring steel is a material specifically designed for springs, characterized by exceptionally high elasticity and fatigue resistance.
-
This type of compression spring has good corrosion resistance and antioxidation properties, with a relatively higher cost.
-
Brass Compression SpringsThis type of compression spring possesses certain corrosion resistance and good electrical conductivity, but has lower strength and elasticity.
-
Copper Compression SpringsThis type of compression spring exhibits excellent electrical and thermal conductivity, but has lower strength and wear resistance.
-
Phosphor Bronze Compression SpringsThis type of compression spring offers good elasticity, wear resistance, corrosion resistance, and electrical conductivity.

Perfect Finishing for Compression Spring
Add a protective film on the surface of compression springs by electroplating, enhancing the corrosion resistance and aesthetic appeal of the springs. Available options include zinc plating, nickel plating, and chrome plating.
Spray a protective layer of epoxy resin, polyurethane, or nylon onto the surface of compression springs to prevent corrosion or wear. This coating is available in various color options for identification or differentiation purposes.
Phosphating treatment creates a phosphating film on the surface of the compression spring, providing a certain level of corrosion resistance. Additionally, phosphating treatment can serve as a base for other treatment methods to enhance coating adhesion.
Passivation is primarily used for stainless steel compression springs, it is forming a layer of oxide film on the springs that enhances the corrosion resistance of it.
Hot-dip galvanizing is a process used to apply a thicker layer of zinc onto the surface of a compression spring by hot dipping, making it more corrosion-resistant than electroplated zinc.
Through a chemical reaction, a layer of oxide film forms on the surface of the compression spring. This oxide film serves to increase the spring’s resistance to corrosion while also enhancing its appearance and reducing light reflection.

Of course, besides helical springs, we also provide various types of wire springs. Just provide us with a sample or drawing, and we can produce them for you.
Yes, we have the capability for secondary processing, allowing us to add the attachments you need at either end or other positions of the compression spring.
We accept payment methods such as T/T, Letter of Credit, Western Union transfer, and PayPal, etc.
Our transaction methods include FOB, CIF, EXW, DDU, DDP, etc.
Yes, you can customize samples. However, since customizing samples requires replacing and re-making the mold, there will be a certain sample fee, which will be fully refunded after you place the order.
The delivery time for standard orders is approximately around 30 days, but it may vary depending on the order quantity.
For custom orders, we need to adjust production line parameters, so the specific delivery time will be determined through further negotiation.
