How to make custom enamel pins

About the size

The size of general enamel pin customization needs to be set according to the purpose and design. It is more appropriate to wear 20-25mm pins on the chest, and the size is calculated according to the longest edge. The possibility of practical operation and price need to be considered when making enamel pin customization. The size of the pin will directly affect the price, the larger the size, the higher the price. Because of the cost of more materials, the work time is longer. Of course, it is not the smaller the cheaper, the size is too small, the design pattern is relatively complex, it is more difficult to do, and even some designs can not be actually operated, like this case the price is relatively high. So in the pin customization time to consider the size of the problem, to find the right cost performance.

About wearing

The size of the design pin is also closely related to the comfort of wearing. Most pins are worn on the left breast, but some conference pins are worn on the collar of the suit, while the armband and collar pin have a relatively fixed position. When wearing the pin, we should pay attention to the size and weight of the pin. If the pin is relatively large and heavy, it is required to increase the puncture needle to prevent the pin from falling. Some compact and lightweight pins can be matched with magnet stickers, and also avoid leaving puncture holes on the clothes. When wearing the pin, also pay attention to the color of the clothes. When pregnant women and children wear pins, try to use magnetic patch accessories to puncture the pins to avoid skin injury.

Material - Zinc alloy

Zinc alloy is the best material for die-casting enamel pins. Zinc alloy has several characteristics that are very suitable for customing enamel pins:

A, good casting performance, can die cast complex shape, thin wall precision parts, casting surface smooth;

B, the surface can be electroplated, spray painting, spraying and other processes,

C, in the die casting does not absorb iron, does not stick to the mold, etc.

D, good mechanical and wear resistance at room temperature, etc.

E, low melting point, melting at 385 degrees, easy to die casting, etc.

Of course, enamel pins made of zinc alloys also have THEIR disadvantages, such as poor corrosion resistance and a much poorer service life than copper pins.

Pin custom process

Process 1. Design the pin artwork.

Process 2. Making pin molds. The black and white line drawings in the artwork represent concave and convex metals. On the sulfate paper printed in a certain proportion, the template is made by the method of photosensitive ink exposure, and then the engraving machine is used to engraving the template according to the appearance of the template. When the die is finished, heat treatment of the die is needed to strengthen the hardness of the die and make it more convenient to hit the metal.

Process 3. Suppression. The heat-treated mold is mounted on the press table, and the pattern is transferred to different pin making materials such as copper sheet or milling sheet.

Process 4. blanking. Make use of the knife mold in advance, the product according to its shape, with a punch to the product down.

Process 5. Polishing. Put the product OF the knife die down into the polishing machine, remove the burr of the stamping, and improve the finish of the product.

Process 6.Welding accessories. Solder the back of the product to the pin standard fittings or fittings required by the customer.

Process 7: Electroplating and coloring the pins. According to customer requirements for the pin electroplating, can be gold plated, silver plated, nickel plated, copper plated, and then according to customer requirements for the pin color, color, high temperature baking, in order to strengthen the color fastness. Through this step, a complete pin that meets the guest's requirements is created.

Process 8: Quality inspection and package them according to the customer's requirements.
