PRODUCTION EQUIPMENT
PRODUCTION EQUIPMENT
BOXN PUNCHING MACHINE
Featuring high tonnage, stable operational stroke, and outstanding process repeatability, the BOXN punching machine is perfectly suited for the swift and accurate fabrication of various structural and metallic components. This advanced equipment empowers our organization to achieve streamlined mass production that guarantees both robust performance and premium aesthetic standards, reliably providing the high-quality componentry required for final machine assembly.
Die Casting Machine
Equipped with advanced capabilities in high-pressure, high-speed, and highly stable operation, the Guangzhou Zhengao Die-Casting Machine enables the precise molding of materials including aluminum and zinc alloys. This process facilitates the production of metal structural components that achieve outstanding mechanical properties, tight dimensional tolerances, and excellent surface quality. Consequently, our products offer guaranteed long-term performance defined by high mechanical strength and superior resistance to environmental factors.
HAITIAN INJECTION MOLDING MACHINE
Leveraging Haitian injection molding technology—known for its superior stability, uniform polymer plasticization, and rapid cycle times—we manufacture high-performance plastic enclosures and internal structural components for communication terminals. This equipment ensures our products meet stringent requirements for high mechanical strength, impact resilience, and environmental durability. Precision molding is simultaneously employed to achieve excellent surface finish and tight dimensional tolerances on external parts.
HAN'S LASER CUTTING MACHINE
Han's Laser cutting equipment delivers exceptional precision, speed, and cutting stability, making it ideal for the intricate machining of metals and engineering materials. For applications like telephone housing production, it ensures critical dimensional accuracy and edge quality, significantly boosting processing efficiency and consistency, which underpins enhanced product durability and protection.
KEYS SORTING MACHINE
The Keys Sorting Machine automatically sorts, inspects, and selects keypad components to ensure stable quality and consistent performance. It identifies size, color, and orientation to minimize human error, improves assembly efficiency, and guarantees uniform tactile feedback. By preventing defective keys from entering production, it enhances overall product quality.
METAL DRILLING MACHINES
Metal drilling machines are used to process holes on metal housings, base plates, and brackets—essential structural components of industrial telephones. With high drilling precision, they ensure accurate assembly alignment, while excellent repeatability supports consistent mass production. As a result, screw holes and mounting positions become more accurate, leading to stronger and more reliable overall assembly.
SOLDERING MACHINE
The Soldering Machine is used for welding metal housings, including stainless steel and other components of industrial telephones. It provides stable, uniform seams and ensures strong structural integrity for products operating in harsh environments. Moreover, it accommodates various metal thicknesses and high-strength alloys while delivering precise and consistent welding performance.
