The handle, as the part of the dumbbell that comes into contact with the user for the longest time, its quality plays a crucial role in the user’s experience. A good handle must have a stable grip, smooth force application, and durability for safety. Baopeng fitness deeply understands the importance of the handle as the “power fulcrum” of the dumbbell, and has thus established a precise production process system to create Baopeng fitness’s dumbbells with longer lifespan and higher quality.
Selected 40Cr alloy steel as the raw material
The foundation of an excellent handle begins with the control of the raw materials. Baopeng fitness chose to use 40Cr alloy steel as the raw material for the handle. This alloy steel material has better wear resistance and rust prevention properties than ordinary steel, and can withstand repeated grasping and impact from drops. This greatly solves the “unreliable durability” problem of ordinary material handles. After the raw materials are warehoused, they are cut according to the requirements of the order.
The millimeter-level processing technology of the CNC lathe
The cut steel is repeatedly ground on a precise CNC lathe. The aim is to create a micro-conical structure that is narrower at the front and wider at the back. The diameter of the ball head assembly at the front end of the handle and the root form a subtle difference. This core design enables the handle and the ball head assembly to achieve a 0-to-0 tight fit when assembled, preventing the dumbbell from loosening due to repeated drops during use. Additionally, on this basis, Baopeng fitness will also weld the two identical materials at the inclined part at the top, providing a double guarantee for the tightness. The entire process is carried out strictly according to the procedures, making the production of the handle more precise and ensuring the quality.
High-density embossed pattern on the handle
Transform the smooth handle into a comfortable and safe one to hold. The embossed treatment is the key. Baopeng fitnessoffers different densities and depths of textures for selection. Common mesh embossing has density options of 1.2mm and 1.5mm. The depth is controlled between 0.3mm and 0.5mm. The texture of the handle not only increases the contact area with the palm but also avoids slipping when sweating. It ensures the comfort of the trainees during long-term use.
In order to ensure a tighter connection between the ball head and the handle, Baopeng will perform heat treatment on the large-sized dumbbell handles before electroplating the handles. This step is to enhance the hardness of the handles and increase their load-bearing capacity, thus preventing the dumbbells from falling off or breaking during training.
Surface multi-layer electroplating treatment
To resist corrosion from sweat and wear and tear during daily training, the handle needs to undergo multi-layer electroplating treatment. Baopeng fitness adopts a layer electroplating process including copper, nickel, chromium, etc. This not only significantly enhances the handle’s waterproof and rust-proof functions, but also keeps the handle surface shiny even after multiple uses. It extends the lifespan of the dumbbell. Before assembling with the ball head, the handle needs to undergo a rigorous salt spray test. A randomly selected handle is placed in the salt spray testing equipment and undergoes a 48-hour continuous test. Only when there is no rusting, peeling, or any other adverse phenomena on the surface of the handle can this batch of handles be judged as qualified.
In summary, Baopeng’s requirements for the dumbbell handle take into account the overall assessment of materials, CNC machining, and surface technology.
From the tough core of 40Cr steel to the millimeter-level taper fit, from the scientific embossing design to the protective coating that passes a 48-hour salt spray test, every aspect is dedicated to making the handle the most reliable and durable power fulcrum in training. This is not just a collection of technologies, but also a solid guarantee for the safety and experience of the trainees.
