Badge of metal
Design: Design the style of the badge according to the needs, draw a detailed design drawing, and determine the shape, size, pattern, text and other elements of the badge.
Mold making: Making molds according to the design drawing, usually using steel molds or copper molds. For complex badges, it may be necessary to use special processing methods such as EDM to make molds to ensure the accuracy and detail of the pattern.
Blank preparation: Select the appropriate metal material, such as copper, iron, aluminum, stainless steel, etc., cut it into the appropriate size and shape, as the badge of the blank. For some high-precision badges, it may be necessary to forge or roll the blank to improve the density and properties of the metal.
Stamping molding: the blank is put into the mold, and the pressure is applied by the punching machine, so that the metal blank is formed under the action of the mold, forming the basic shape and pattern of the badge. The stamping process needs to control the pressure, speed and accuracy of the punch to ensure the quality and consistency of the badge. For some complex patterns, it may be necessary to carry out multiple stamping or use a combination of molds to complete.
Surface treatment: Surface treatment of stamped badges to improve their corrosion resistance, wear resistance and decoration. Common surface treatment methods include electroplating, nickel plating, chromium plating, gold plating, painting, passivation and so on. Plating can make the badge surface to obtain bright, uniform metal coating, increase its gloss and corrosion resistance; Paint can be selected according to the need of different colors of paint, to provide rich colors and decorative effects for the badge.
Detail treatment: the edge, corner and other details of the badge are polished, polished, etc., so that its surface is smooth, without burrs and flaws. For some badges that need to highlight the three-dimensional sense, they can also be embossed or etched to enhance the visual effect of the badge.
Assembly: If the badge has accessories, such as pins, hooks, etc., it needs to be fitted to the badge. During the assembly process, the fastness and reliability of the accessories should be ensured to ensure that the badge will not be loose or fall off during use.
Plastic badge
Design: Use computer aided design (CAD) software to design the badge, draw a three-dimensional model, and determine the shape, color, pattern and other details of the badge.
Mold making: Making plastic molds according to the design model, usually using injection molds. The accuracy and quality of the mold directly affect the molding effect of the badge, so it is necessary to use high-precision processing equipment and technology to manufacture the mold.
Material selection: According to the use requirements and performance characteristics of the badge, choose the appropriate plastic materials, such as polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), acrylic and so on. Different plastic materials have different physical properties, chemical stability and processing properties, and need to be selected according to the actual situation.
Injection molding: The plastic particles are heated to a molten state and then injected into the mold, and under the cooling of the mold, the plastic quickly solidifies and forms the shape of the badge. During the injection molding process, parameters such as temperature, pressure and injection speed need to be controlled to ensure that the plastic can be evenly filled with the mold to avoid bubbles, deformation and other defects.
Surface treatment: The plastic badge after injection molding is surface treated to improve its appearance quality and decoration. Common surface treatment methods are printing, spraying, hot stamping, screen printing and so on. Printing can print various patterns, words and colors on the surface of the badge; Spraying can provide different colors of coating for the badge to increase its beauty; Hot stamping can be printed on the surface of the badge gold or other colors of the pattern or text, to enhance the grade and texture of the badge.
Cutting and trimming: After the injection molded badge is removed from the mold, it needs to be cut and trimmed to remove excess scrap and burr, so that the edge of the badge is neat and smooth. For some badges that require special shapes, they can also be processed by laser cutting or stamping cutting.
Ceramic badge
Design: Design the style of the badge, draw the design drawing, determine the shape, size, pattern, color and other elements of the badge. Due to the particularity of ceramic materials, the design needs to take into account the molding process and shrinkage rate of ceramics and other factors to ensure that the final product can meet the design requirements.
Mud preparation: Select the appropriate ceramic mud, adjust the formula and mix as needed. The mud is refined to remove impurities and bubbles and improve the plasticity and uniformity of the mud. Then the mud material is made into the desired shape and size of the body, which can be manually formed, pulled blank forming, grouting forming and other methods.
Drying and burning: the body is dried naturally or in a drying kiln to remove the water in the body. After drying, the blank body is burned at a temperature of 800℃ -1000 ℃, which can improve the strength and hardness of the blank body and prepare for subsequent processing and decoration.
Decoration: The blank body after burning is decorated, which can be painted, carved, decal and other methods. Painting is to draw a variety of patterns and colors on the surface of the body with ceramic pigments; Engraving is through the tool on the surface of the billet carved uneven patterns, increase the three-dimensional sense of the badge; Decals are pre-printed ceramic floral paper pasted on the surface of the blank, and then fired to fix it to the badge.
Glaze and firing: Glaze is applied on the surface of the decorated blank body, and the glaze can form a smooth, hard glassy layer on the surface of the badge, which not only increases the beauty of the badge, but also improves its corrosion resistance and wear resistance. After glazing, the badge is put into the kiln for firing, the firing temperature is generally about 1200℃ -1400 ℃, the specific temperature depends on the type of ceramic material and glaze. During the firing process, the ceramic body and glaze undergo a series of physical and chemical changes, resulting in the formation of a hard, dense ceramic badge.
Post-processing: The ceramic badge after firing needs to be cooled, cleaned, inspected and other post-processing processes. The surface of the badge is inspected, and if there is a flaw or defect, it needs to be repaired or reworked. Finally, the badge is packaged for storage and transportation.
