In the field of luggage accessory production, high-carbon steel has become the preferred material for manufacturing core components such as luggage frames and drawbar connectors, thanks to its high strength and hardness. However, processing high-carbon steel has always been an industry challenge: its material properties easily lead to problems like unstable weld joints and deformation during welding. Moreover, the traditional processing flow requires separate operations of multiple processes—"forming - welding - annealing"—resulting in low efficiency and difficult precision control. The emergence of the medium-frequency frame bending and butt welding integrated machine has precisely overcome the processing pain points of high-carbon steel luggage accessories, becoming an "exclusive tool" for handling such materials in the industry.
Why is high-carbon steel more suitable for processing with medium-frequency welding? The core reason lies in the high compatibility between medium-frequency welding technology and the material properties of high-carbon steel. High-carbon steel has a relatively high carbon content; if the temperature is not properly controlled during welding, hardening structures are likely to form, leading to brittle weld joints. Additionally, luggage accessories have strict requirements for joint strength, as they need to withstand pulling and impact during daily use of the luggage—ordinary welding methods can hardly meet such durability needs. By increasing current output, the medium-frequency welding machine can accurately control the welding temperature and heat penetration depth, enabling full fusion of high-carbon steel joints at high temperatures. At the same time, combined with subsequent annealing treatment, it can effectively eliminate welding stress and prevent joint brittleness. Compared with the "cold solder" and "weld joint oxidation" issues that often occur in traditional high-frequency welding, medium-frequency welding can improve the joint strength of high-carbon steel accessories by more than 30%, fully meeting the durability requirements for long-term use of luggage accessories.
More importantly, the medium-frequency frame bending and butt welding integrated machine realizes the integrated completion of three core processes—"forming - welding - annealing"—completely changing the inefficient traditional processing mode. In traditional production, high-carbon steel accessories first need to be formed into frames using a wire bending machine, then transferred to welding equipment for joint welding, and finally sent to an annealing furnace to eliminate stress. The transfer and adjustment between processes alone waste a lot of time, and repeated handling easily causes deformation of accessories, affecting precision. Through integrated design, this machine combines the frame bending mechanism, medium-frequency welding system, and annealing module into one unit: after the wire is fed in, the high-precision frame bending mechanism first completes forming according to preset parameters (such as the rectangular or arc structure of luggage frames); then the medium-frequency welding system automatically performs fusion welding on the joints; finally, it directly enters the annealing process to eliminate internal stress. The entire process requires no manual intervention or accessory transfer, and finished products can be produced in a single process—production efficiency is more than doubled compared with the traditional mode.
For luggage accessories, "precision" and "aesthetics" are equally important, and this machine sets an industry benchmark in both aspects. Its processing error can be accurately controlled within ±0.1mm (commonly referred to as "±0.1mm tolerance" in the industry). Whether it is the side length of the luggage frame or the joint gap of the weld, high consistency can be maintained, ensuring the compatibility between the accessory and the main body of the luggage. At the same time, the high-temperature fusion process of medium-frequency welding makes the weld joint smooth and flat, with no obvious weld beads or oxidation marks. It can be directly used for assembly without subsequent grinding, which not only saves processes but also ensures the appearance quality of luggage accessories. Luggage made with such accessories not only has a stable frame that is not easily deformed but also significantly improves the product grade through the delicacy of details.
The operational convenience and durability of the machine further reduce the production threshold and long-term costs for enterprises. It is equipped with a multi-language intelligent system, supporting multiple operating languages such as Chinese and English, and adopts a dual-control mode of buttons and touch screen. Even inexperienced new operators can master basic operations proficiently after 30 minutes of simple training, greatly reducing the enterprise's training investment. In terms of data storage and parameter calling, the machine can preset processing parameters for various luggage accessories. When switching product models, there is no need for repeated debugging, further improving the efficiency of production change. Meanwhile, the machine uses high-quality core components, and its service life can reach more than 10 years under normal use. The manufacturer also provides a 1-year warranty service, with professional support from equipment installation and commissioning to later maintenance, effectively reducing the enterprise's equipment maintenance costs and downtime losses.
From the perspective of market demand, as consumers have increasingly higher requirements for the durability and quality of luggage, the market share of high-carbon steel luggage accessories is gradually expanding. With its accurate processing capability for high-carbon steel, integrated efficient production mode, and stable precision and durability, the medium-frequency frame bending and butt welding integrated machine has become a key piece of equipment for luggage accessory enterprises to enhance their competitiveness. Whether it is mass production of standardized luggage frames or customized special-shaped accessories, this machine can always deliver "efficient, precise, and stable" performance, helping enterprises overcome high-carbon steel processing challenges, produce high-quality products that meet market demand, and gain an advantageous position in the fierce industry competition.
