Metal luminous characters have become a popular choice for outdoor advertising and brand display due to their strong texture and high durability. The processing of such products involves multiple precision procedures and cannot be separated from the collaborative cooperation of a series of professional equipment. Each equipment plays a key role in the process flow.
Laser cutting equipment is the “first gateway” for metal luminous character processing. It uses high-energy laser beams to accurately cut metal materials such as stainless steel, aluminum plates, and galvanized plates, and can easily complete the processing of font outlines, notches, and detailed patterns. Its cutting accuracy of 0.1 millimeters can perfectly reproduce the curves and sharp angles in the design drawings, ensuring smooth and burr free edges of the letter shell and eliminating a lot of post-processing polishing processes. For metal sheets of different thicknesses (usually 0.8-3 millimeters), the equipment can automatically adjust the laser power and cutting speed, ensuring that thin materials are not burned through while achieving efficient penetration of thick materials. It is the core equipment for achieving complex font shapes.
The bending machine is responsible for the three-dimensional forming of metal shells. The flat metal sheet that has been laser cut needs to be bent at specific angles by a bending machine to form a three-dimensional structure of the letter shell. Modern CNC bending machines can preset bending parameters through programming to ensure that the side angles and heights of fonts in the same batch are completely consistent, especially suitable for standardized production of chain brands. For special shapes such as curved fonts, some bending equipment can also be used in conjunction with molds to achieve curved bending, making the three-dimensional feeling of metal letter shells more natural.
Welding equipment is used to fix the various components of the shell as a whole. The laser welding machine, with the characteristic of locally melting metal at high temperatures, can complete precision welding without damaging the surface of the shell. The welding points are small and firm, especially suitable for splicing materials such as stainless steel; The argon arc welding machine is suitable for welding non-ferrous metals such as aluminum plates, and uses inert gas protection to prevent oxidation and discoloration of the welding points. For large metal luminous characters, it is necessary to cooperate with fixtures during the welding process to ensure that the character shell does not deform and to ensure the dimensional accuracy of the final product.
Grinding and polishing equipment is the key to improving the texture of metal characters. Angle grinder combined with grinding discs of different particle sizes can quickly process welded joints and burrs; The mirror polishing machine can use a high-speed rotating polishing wheel to create a mirror effect on the metal surface, enhance light reflection, and make luminous characters present a bright metallic luster even during the day. Some automated polishing equipment can also automatically adjust the polishing path according to the font shape, greatly improving processing efficiency.
The slotting machine plays an important role in the assembly of metal shells and panels. It can accurately create uniformly wide card slots on the side of the letter shell, ensuring seamless embedding of acrylic or PC panels. This not only ensures the uniformity of the luminous effect, but also enhances the sealing of the overall structure, effectively preventing rainwater and dust from entering the interior and damaging the light source.
The collaborative operation of these devices, from flat cutting to three-dimensional forming, from structural fixation to surface beautification, jointly constructs a complete processing system for metal luminescent characters. Among them, laser cutting equipment, as the “gatekeeper” of modeling accuracy, directly affects the smoothness of subsequent processes and the quality of the final product, becoming an indispensable core force in metal luminous character processing.
