In furniture hardware production, stamping parts, with their advantages of high precision and stability, have become a key processing method for core components such as small handles, bedroom lock door handles, and soft-closing cupboard hinges. Guangdong Huitailong Technology Co., Ltd. has been deeply involved in the furniture hardware industry for many years and has mastered mature stamping parts processing technology. The details of this process not only determine product quality but also directly affect the user experience and service life of home hardware. Below, we will explain the key processing steps for furniture hardware stamping parts.
First, the raw material selection and pretreatment steps are the foundation for ensuring the quality of stamped parts. HUTLON carefully selects cold-rolled steel, stainless steel, and aluminum alloy materials to meet diverse hardware needs. Small handles are typically made of stainless steel with a thickness of 0.8-1.2mm, balancing lightweightness and load-bearing properties. Bedroom lock door handles are made from higher-strength cold-rolled steel, which is galvanized for enhanced rust resistance. The raw materials are first cut to size using flattening and shearing equipment, followed by pre-treatment processes such as degreasing, pickling, and phosphating to remove surface oil and oxide layers, ensuring stable material form during subsequent stamping and minimizing die wear.
Next comes the core stamping process, which includes multiple steps, including blanking, drawing, bending, and punching. Taking the hinge arm processing of soft-closing cupboard hinges as an example, HUTLON employs multi-station progressive die stamping technology. Using a continuous die, the process sequentially completes blanking (punching out the hinge arm blank), stretching (shaping the curved structure), punching (reserving mounting holes), and bending (forming the hinge opening and closing angle). The entire process is automated, with accuracy controlled to within ±0.05mm, eliminating dimensional deviations caused by manual operation. For complex stamped parts like door closer housings, a hot stamping process is also employed. By heating the material, the deformation resistance is reduced, enabling the complex shape to be formed in one step, while also improving the housing's strength and impact resistance.
Subsequent surface treatment determines the stamped part's appearance and durability. Hutlon uses different processes based on product applications. Small handles and bedroom lock door handles are typically electroplated (chrome or nickel) or spray-coated. The former enhances the metal's texture and rust resistance, while the latter allows for a variety of colors to match home styles. The core components of spring door closers undergo carburizing and quenching to enhance surface hardness and extend the life of the springs and transmission components. Furthermore, all stamped parts undergo quality inspections such as salt spray testing (testing time ≥ 48 hours) and load testing to ensure resistance to rust and deformation in humid, high-frequency environments.
"The precision of furniture hardware stamping parts is directly related to the feel and safety of home hardware." A company engineer explained that by introducing high-precision stamping equipment and intelligent testing systems, the company continuously optimizes process parameters, ensuring more stable cushioning for soft-closing cupboard hinges and more precise closing speed for door closers. HUTLON will continue to explore the integration of stamping technology and new materials to provide consumers with more durable and aesthetically pleasing furniture hardware products, promoting quality upgrades in the home hardware industry.
