Soft Enamel and Hard Enamel are two enamel filling processes commonly used in the making of badges, jewelry, and other crafts. The main differences are appearance, feel, manufacturing process and cost. Here's a breakdown:

1. ** Appearance **
- ** Soft enamel **
- After the color is filled, it is lower than the surface of the metal line, and it has an obvious concave and convex feeling to the touch.
- The colors are usually brighter and slightly less shiny.
- A transparent protective resin can be added to the surface to form an effect similar to a smooth surface, but this method is still soft enamel.

- ** Hard enamel **
- Color fill flush with metal lines, smooth surface.
- The luster is stronger, the appearance is more advanced and delicate.

2. ** Touch **
- ** Soft enamel ** : The surface is concave and convex.
- ** Hard enamel ** : The surface is completely smooth.

3. ** Production process **
** Soft enamel **
1. Fill the color into the metal groove and bake to cure.
2. No additional polishing is required after baking, and the process is relatively simple.

** Hard enamel **
1. Fill the color and bake it several times, each color needs to be cured separately.
2. After baking and polishing, ensure that the surface is flush with the metal wire and smooth.
3. The production process is more complicated and time-consuming.

4. ** Durability **
- ** Soft enamel ** : Due to the low surface, it is easier to scratch, but the durability will be improved after adding protective resin.
- ** Hard enamel ** : surface wear resistance, longer service life.

5. ** Cost **
- ** Soft enamel ** : simple production, low cost.
- ** Hard enamel ** : The process is complex and the cost is higher.

Application scenario
- ** Soft enamel ** : Suitable for budget limited, need to make bright colors or special touch requirements of the design, such as event badges, souvenirs.
- ** Hard enamel ** : Suitable for the pursuit of high-end, durable and textured products, such as high-end badges, brand jewelry.

Summary: **
The choice of soft or hard enamel mainly depends on the budget, appearance requirements and use scenarios. If the pursuit of high-end texture, it is recommended to choose hard enamel; If you need a cost-effective and colorful product, soft enamel is a good choice.
