The craftsmanship of custom medals
Medals are a testament to the superior winners of the various competitions. We customize the shape, pattern and style you want, then it can be divided into sports medals and commemorative medals according to the use.
The process of custom medals making as follow:
With the popularization of computer technology, computer drawing replaced the previous manual drawing.
The designed drawings are imported into the carving software for 3D modeling or editing. After that, we carve on the mold by machine. The thickness of the carving knife should vary with the thickness of the lines in the drawing. Comparing with the artwork, we can check if the mold is correct and if the lines of the design are continuous on the mold.
Digging on the mold in order to let the raw material flowed into the mold. The quantites and size of the rabbet depended on the shape of medal. By doing this, it improves the products smoothness and very good help for controlling the reject ratio.
Put the mold into the machine tool of electrical discharge machining. Adjust the size of the copper plate according to the size of the part of sand effect requested by customer. And adjust the current to control the size of the sand.
In the process of engraving the mold, there will be some traces of the carving knife leaving on the surface of the mold and needless sandblasted as well. We will use 220# oilstone, 350# oilstone, 450# oilsone and 600# oilstone to polish the mold step by step first, and then polish the smaller corners and letters with fiber. The edge will be polished as well.
High temperature treatment of the mold in order to improve the hardness of the mold, go through 900 degrees of heat for 2 hours and then turn back again with 300 degrees for 5 hours. In this way we can avoid mold deformation or collapse caused by the not enough hardness of the mold.
There will be oxide layer caused by heat treatment for the mold, so polish the mold again.
The die machine should be suitable to the products. Too large products with small machines will lead to the product line and pattern not full enougn. Put the mold on the machine and adjust the position of the front mold and the back mold to reach the consistency. Adjust the pressure of the machine as well in order to make full products. We will check samples first before mass production. If all is ok, we will let the machine work automatically in high efficiency.
Grinding the rough edge by file or sander.
Polishing the edge and the surface of the frontside and backside of the products to make it smooth.
Firstly clean the surface of the products after polishing. Secondly, plate the background in copper color. Then we can plate any colors requested by order. Such as shiny gold/ silver/ copper, antique gold/ silver/ copper, matt gold/ silver/ copper, limitation gold, spray black// blue/ white and so on. Finally, cover the products with oil and baking for 2 hours in the oven in order to protect the electroplated coatings from oxidation.
Take off the bad products which have bubble, watermark on the surface. And take off the one that is off color as well.
We fill the enamel color according to Pantone Solid Coated. Selectting a suitable cylinder to fill colors according to the input area size. Need to be very careful to avoid spill or color changing. After that, we clean the surface of the products since there will be a few colors spill onto the surface unneeded.
After color filling, we need to put the products into the oven to strengthen the color fastness.
Installing the attachment to the products. Like ribbon ( sublimated ribbon, plain ribbon and printed ribbon), rope and chain, ect.
