Carbon Steel Black Oxide Non-standard Custom Size Compression Spring Helical Coil Spring

This cylindrical helical compression spring is manufactured by using high elastic carbon spring steel wire through a one-step process on a CNC machine. It is strengthened in mechanical properties through a tempering process. The surface is treated with high-temperature blackening oxidation. It is a universal elastic functional component for industrial production, equipment maintenance, and hardware assembly scenarios.

The entire series covers multiple gear ratios, outer diameters, and free heights. From micro-sized precision springs to large-stroke heavy-duty springs, stable supply is available. At the same time, non-standard sizes and elastic parameters can be customized according to drawings and samples, and it can flexibly adapt to different installation spaces and load levels of usage requirements.

Precise winding, uniform force distribution

Standardized production using fully automatic spring rolling equipment, with uniform pitch, regular coil shape without deformation. The ends are polished for a high installation fit; the axial pressure is evenly transmitted, and there is no lateral deviation or twisting problem.

Linear elasticity, stable rebound

Strictly following spring mechanical design standards, maintaining linear elastic output within the effective compression stroke. The rebound response is rapid without stalling, suitable for various working conditions such as precise reset, buffer and shock absorption, and elastic compression.

Blackening protection, corrosion-resistant and rust-proof

Overall undergoes high-temperature blackening oxidation treatment, forming a dense protective film layer on the surface. Under normal indoor conditions, it can resist moisture and mild corrosion. The matte black appearance has uniform texture and combines protection and decorative effects.

Heat treatment strengthening, long fatigue life

The finished product undergoes shaping and tempering treatment, enhancing the toughness and anti-fatigue strength of the material. It is unlikely to experience plastic deformation or fracture during repeated compression, and the elastic force attenuation rate is low, resulting in a longer service life.

Comprehensive specifications, wide range of in-stock products: Covering multiple sizes ranging from 0.2mm to 5.0mm wire diameter and 3mm to 60mm outer diameter. The free height can be adjusted as needed. Most standard specifications are in stock, and no mold needs to be made to quickly adapt.

Full chain quality control, high batch consistency: Each batch of products undergoes size inspection, elasticity test and basic corrosion resistance test. Parameter errors are controlled within industry standards, ensuring uniform performance for batch supply.

Support for non-standard customization, strong adaptability: Customized variable-diameter springs and special-shaped compression springs can be provided according to customer requirements. Raw materials such as stainless steel, piano steel, and copper can also be replaced, or surface treatment schemes such as galvanization, nickel plating, and electrophoresis can be combined.

Factory direct supply, outstanding cost performance: The direct supply from the source factory reduces intermediate circulation links, and bulk purchases have price advantages. At the same time, small batch samples can be supported to reduce the cost of customer selection and trial.

Q1: Can I install your anchor bolts in pre-existing concrete structures?

A: In many cases, it is possible to install our anchor bolts in pre-existing concrete structures. However, the process may require special techniques such as drilling and using chemical anchors or expansion anchors in some cases. It is important to assess the condition of the existing concrete and consult with a professional or our technical team to determine the best installation method.

Q2: How do I select the right size of anchor bolt for my project?

A: Selecting the right size of anchor bolt depends on several factors, including the type of structure, the load it will bear, and the characteristics of the base material. You should consider the tensile and shear forces that the bolt will be subjected to and refer to our product specifications and engineering guidelines. Our sales team can also assist you in choosing the appropriate size based on your project requirements.

Q3: What is the difference between a chemical anchor bolt and a mechanical anchor bolt?

A: A chemical anchor bolt uses a chemical adhesive to bond the bolt to the base material, providing a strong connection. It is often used in situations where a high level of precision and load-bearing capacity is required. A mechanical anchor bolt, on the other hand, relies on mechanical means such as expansion or friction to secure the bolt in place. The choice between the two depends on factors such as the type of base material, the application requirements, and the environmental conditions.

Q4: Do your anchor bolts come with any warranty?

A: Yes, we offer a warranty on our anchor bolts. The specific terms and conditions of the warranty may vary depending on the product and the application. Please refer to our warranty policy or contact our customer service team for more information.
