Preface: The manufacturing process of lapel pins generally includes stamping, casting, hydraulic press, and corrosion, among others. Among them, stamping and casting are the most common. The coloring process involves various techniques such as faurang (Jingdezhen blue), imitation faurang, baking paint, glue dripping, printing, etc. The material of lapel pins is generally zinc alloy, copper, stainless steel, iron, pure silver, pure gold, and other alloy materials.
Here is 2025 the most- omprehensive analysis of lapel pin process

1. Stamping process: 

The designed pattern is engraved on the mold, installed on the stamping machine, and the metal material is placed under the mold. Through the pressure of the stamping machine, the pattern is transferred onto the metal material, and then the material is removed according to the product shape using the die. This process has high production efficiency and relatively low cost, and can produce refrigerator stickers with regular shapes and clear patterns, suitable for large-scale production.

2，Die-casting process:

The molten alloy liquid is poured into the die cavity, and then rapidly filled into the mold cavity made of steel. Under the pressure, the alloy liquid solidifies to form a casting. This process can produce complex-shaped and high-precision three-dimensional lapel pins, with good surface quality and high strength. However, the equipment cost and mold cost are relatively high, and it is suitable for manufacturing high-quality and high-demand three-dimensional products.

3，Corrosion Process:

Mainly using materials such as bronze, stainless steel, iron, and aluminum. After being corroded by chemical solutions, it forms concave patterns. Then, it undergoes coloring, grinding, polishing, cutting, welding pins, electroplating and other processes to be completed. Its characteristics are fine lines and a transparent resin layer added on the surface, which gives a slight raised feeling when touched by hand. The color is bright. This process is suitable for making products with large sizes and complex pattern lines, such as numbers, employee IDs, names, nameplates, badges that need to be bent, tags, etc. The corrosion process can produce detailed and realistic pattern effects, with a unique artistic sense. However, it causes certain pollution to the environment, so it is necessary to pay attention to environmental protection and safety.

4.Soft enamel process:

A single or multiple layers of paint are sprayed onto the surface of the metal lapel needle, and then dried and cured through high-temperature baking. The enamel coating process can give the surface of the refrigerator sticker rich colors and luster, such as matte, glossy, metallic, etc. At the same time, it can also increase the hardness and wear resistance of the surface, thereby extending the service life of the product.

5,Hard enamel process:

The enamel glaze is applied to the surface of the metal lapel needle, and after being fired at high temperature, the glaze fuses with the metal surface, forming a layer of bright and colorful enamel. This enamel technique can produce lapel needles with rich colors and exquisite patterns, possessing high artistic value and ornamental appeal. However, the process is complex and the cost is high.

6,UV printing 

he printing is carried out using UV-curable ink. Through ultraviolet radiation, the ink is instantly cured onto the metal surface. The UV printing process can achieve high-precision pattern printing, with bright and saturated colors, as well as excellent wear resistance and corrosion resistance

7,Transparent enamel process:

Transparent completes product production based on the production of soft enamel. The production process is the same, except we use clear paint. After the product is produced, you can clearly see the texture on the bottom

8,Pearlescent enamel pins

Pearlescent enamel pins are also called Pearl Effect En pins amel. This craft features hidden marble veins that make each product unique. Under the light, this marble pattern becomes clear and has better visual effects.

9 Luminous  Glow in the Dark enamel pins

If you need to hold an event at night, then Luminous Glow in the Dark enamel pins are your best choice. This kind of lapel pin can glow in dimly lit environments. However, the disadvantage of this process is that there are very few colors to choose from.

10.Rhinestone

Custom rhinestone lapel pins or brooches never go out of style and they are often used on important occasions. Such as company anniversary, political party activities, high-end party souvenirs. . Gemstones can be set in a variety of metals, and with a wide selection of colored gemstones, different enamel colors and a variety of metal finishes, we can complete all creative designs to suit your wishes.

11,Glitter

We can add glitter. This is a very fine and colorful powder on the basis of soft enamel, hard enamel or printing process. Make your designs shine

12,Spinning Pin

The rotating pin is an advanced variation on the traditional lapel pin that introduces a dynamic element that makes it unique. We use zinc alloy to make this lapel pin. Because zinc alloy has good moldability.

13.lenticular pin

The design of the cat’s eye pins （lenticular pin） needs to take special consideration of the presentation of optical effects. Designers need to use vector software (such as CorelDRAW PS adobe Illustrator) to draw patterns and clarify the color division, reflective area and the direction of dynamic lines. If grating effects are involved, multi-layer gradients or dynamic patterns need to be designed to adapt to the refraction of the grating sheet.
