How do we produce aluminum carabiners？

When many customers choose buckle, the first thing they care about is the carabiner price; but after the actual cooperation, they are more concerned about:
“How did you make this buckle? How to produce in your way?”

Actually, this article will introduce our carabiners production process. You can see the authenticity of our factory through this information. This is not a simple manufacturing process, but a combination of manual, details, people, and sense of responsibility behind a small hardware product.

So today, we want to share with you how our factory produces a stable, durable, and fashionable aluminum alloy gear clip step by step.

Here is our carabiner production process based on the 6061 and 6063 aluminum alloy：

1. Bending Forming

Everything starts with an aluminum bar. We use 6061 or 7075 aluminum alloy to .

Preliminary bending and forming through precision molds to ensure that each hook has a standard shape and size.

2.Flatten Ends

We flatten both sides of the bent carabiner to create a stable support point for the spring component.

3.Trimming & Punching

Then, we punch holes on both sides of the fixed point to ensure accurate installation of the spring assembly in the next step.

We use a custom stamping die to ensure that the hole position of each button is accurate and consistent.

4.Surface treatment: Manual Polishing OR Vibration Grinding

This is an important step to determine the “look and feel”.

Some customers want a smooth, delicate and shiny surface. The product requirements are high and strict, so we will use manual polishing, through dozens of cloth wheel grinding, to make the surface smooth and the sharp edges of the carabiner flat;

Some customers pay more attention to cost and batch efficiency, so we use vibration grinding to uniformly process batches to make the appearance clean and not hurt the hands.

Customers can choose the most suitable one according to their needs for the product and the application field of the product.

5. oxidation–Anodizing

Color is not only about appearance, but also about corrosion resistance. We use an environmentally friendly anodizing aluminum clip process to form a dense protective film on the aluminum surface. The color selection can be customized, and it is scratch-resistant and anti-fading.

Customers can also choose sandblasting, and the surface effect of the buckle is completely different.

  • If you want a more delicate and beautiful surface with uniform color → Glass yarn
  • If you want a high surface roughness and strong powder spray adhesion → Diamond sand

6.Hand Assembly of Spring & Shrapnel

Whether a carabiner is easy to use depends on the “opening and closing feeling”. The material and elasticity of the spring will affect the smoothness and stability when you use it. Moreover, it is manually installed by skilled workers one by one to ensure that the elasticity is moderate, it will not cut your hands, and it will not rebound and fail.

7.Riveting

After installing the spring, we firmly secure it with rivets. We use special equipment and molds to control the riveting depth to avoid the spring loosening or crushing the spring.

8. Calibration Spring Rod

The last step is to manually check the spring elasticity, opening and closing smoothness, and whether the spring is loose. We ensure that each piece opens smoothly and closes securely.

This is more than just a production process

For us, a carabiner is not a small piece of hardware, but a product that goes to market with the customer’s brand.

If you’re planning to develop a carabiner under your brand and are looking for stable technology, flexible customization, and long-term cooperation, we sincerely invite you to get in touch with us.

We meet many customers who ask:

  1. Can the logo be customized on one side or both sides? Where can I place the logo?
  2. Can the Gate and Spine be made in different colors?
  3. What material are your carabiners made of? Are they suitable for mountaineering?

Our answer is:

  1. Regarding the carabiner, we usually place the logo in the middle of the spine to highlight the brand most effectively, which is the most beautiful and can show the company’s logo brand. We can also customize the logo on one or both sides, and we will try our best to meet customer requirements.
  2. We can make the gate and spine in different colors based on your preferences. But if it is not the existing color of the product, we need to charge a color adjustment fee.
  3. We have three types of carabiners: 6061 & 6063 & 7075 aluminum alloy carabiners, divided into different application areas.

·6061/6063 carabiner is suitable for promotional gifts, fashion accessories, outdoor activity accessories (camping, hiking). we also provide engraved 6063 carabiner clip.

·7075 carabiner is used for rock climbing and is used in scenes that require load-bearing capacity
