How Do You Get Matte Or Textured Finishes Through Sandblasting? How?
Sandblasting is a powerful method to create smooth or textured surfaces on gold or silver coins and medals. Why and how do you use this technique?
Surface Preparation- The coin or medal is placed in the form of a cabinet or chamber with a nozzle connected to an air compressor. The chamber may be enclosed to protect the abrasive material employed during the procedure.
Abrasive Material Select - Abrasive particles such as glass beads, aluminum oxide, silica carbide, sand and so on are propelled at high speed on the surface.
High-Pressure propulsion: Abrasive particles are launched onto the surface by using compressed gas or other high pressure system. The finish and texture of the surface is dependent on the force and speed that the particles strike the surface.
Texture creation. The effect of an abrasive surface alters the topography of the surface creating a textured matte finish. It can be used to create a smooth surface, or to create rough textures in certain areas.
Sandblasting is controlled by the intensity as well as duration and angle of application. This permits different types of finishes and textures. Different abrasives can be used to produce different results.
Sandblasting: Why is it necessary?
Texture Variation- Sandblasting permits for the creation of diverse textures or finishes, like matte, frosted, or grainy surfaces, which adds visual interest and unique features to metals or coins.
Aesthetic Enhancement: Sandblasting changes the appearance of the surface, reducing light reflection and diminishing shine. This can increase the coin's or medal's visual appeal. Matte finishes in particular, draw attention to certain design elements as they minimize reflections.
Anti-Glare properties - By using sandblasting techniques, a smooth or matte surfaces can be created. This helps reduce glares as well as reflections. The coins and medals are attractive and clearer to view with no light interference.
Design elements that are contrasted- Sandblasting can create contrast between polished and textured parts of a coin or medal. This allows you to draw attention to particular features or to add visual depth.
Sandblasting is a great way to customize and create distinctive designs. It lets you make your mark artistically and create metal and coins in a variety of designs and textures.

How Are Gold Blanks Fed Into Coin Presses And Stamped Under High Pressure During Minting?
During the coining process, blanks of gold are loaded into coin presses under intense pressure. Then, they are stamped to produce completed coins or medals. Here's a summary of the how to load blanks.
Loading gold-plated blanks into a feeder that is connected to the coin press takes place after they've been prepared, inspected and assessed. This feeder system provides the constant quantity of blanks for the coin press.
Feeding Blanks in the Press
The feeder system is used to feed the blanks into the striking chamber inside the coin press one at a time. This ensures the precise positioning of each blank before stamping.
Alignment of Positioning
The blanks are aligned in the press and then placed in the room for striking, making sure they are perfectly placed to enable the stamping.
Striking in High Pressure
The coin presses exert immense pressure on gold blanks by using two dies - one stationary and one mobile. The stationary die contains the impression of the design that is negative while the moveable die is the hammer.
Die moves and strikes the blanks using a lot of force. This transfers the design onto the surface of the blank. Die pressure results in relief raised and details on the coin.
Repetition Striking (Optional)*
To produce an image or design that is sharper and clearer, multiple strikes can be used on high-quality coins or collectible editions. Each strike refines the surface characteristics of the blank.
Collection and Ejection
After they have been struck, the newly-minted coins or medals are ejected from the press and placed in containers or trays. They undergo inspection for quality control to make sure that the stamped designs meet the standards and requirements set by the manufacturer.
Post-Processing-
Based on the specifications of the mint or design, coins and medals can undergo additional treatments, such as edge lettering or reeding as well as post-strike treatment.
The process of stamping gold blanks using high pressure is vital because it transfers the desired design to the blanks of gold. Then, they are transformed into finished coins or medals ready for collection, circulation or for commemoration. Precision is required, as even a slight variation in the pressure or alignment of the gold blanks could result in a negative impact on the look and quality of the finished product.
