How Can You Achieve Matte Or Textured Finishes Through The Process Of Sandblasting? And How?
Sandblasting is an effective technique to create rough or matte surfaces on silver or gold coin and medals. What is the reason and how is this method used?
Surface preparation: The coin is placed inside a box or cabinet fitted with an air compressor as well as the nozzle. This chamber can be enclosed in order to protect the abrasive material used during the procedure.
Abrasive Material Select - Abrasive particles such as glass beads, aluminum oxide, silica carbide, sand and so on are launched at high speed onto the surface.
High-Pressure propulsion: Abrasive particles can be delivered to the surface of the surface by with compressed gas or a different high-pressure system. The texture or finish is determined by the force and speed at which particles impact the surface.
Texture Creation- The force of the abrasive particles on the surface produces a rough or matte appearance by altering the surface's topography. This process lets you roughen specific areas or create a texture that is uniform across the surface.
Controlled Application - The intensity and duration, as well as angle and application can be controlled to create various textures or surfaces. Different abrasives are employed to create different effects.
Sandblasting is used for a variety of reasons.
Texture variation - Sandblasting can produce a variety of different textures and finishes, including smooth, grainy, frosted or textured surfaces. This adds visual interest to medals or coins.
Aesthetic enhancement- Sandblasting may alter the surface appearance by diffusing light and decreasing shine. This could improve the appearance of a coin. Matte finishes be used to highlight certain design features by reducing the glare.
The anti-glare properties of using sandblasting, a matte or textured surface can be made. This helps reduce glares as well as reflections. The medals and coins look more appealing and clearer to view without interference from light.
Contrasting Design Elements. Sandblasting produces contrast between polished areas and those that are textured on the coin. It can be used to highlight certain design elements or to give them visual depth.
Sandblasting offers a variety of customization options that allow for artistic expression and permits medals, coins, or other items to be designed with different textures or finishes unique to the design.
Sandblasting is a new technique that can be used on gold coins to achieve different textures on the surface. It also improves the overall appearance of the medals.

How Are Gold Blanks Fed Into Coin Presses Under Extreme Pressure? And Then Stamped?
During the coining process the gold blanks are loaded into coin presses at intense pressure. Then, they are stamped to produce finished medals or coins. This is a brief overview of loading blanks.
The gold blanks are placed into the feeder system, that is connected to coin presses. This feeder system is accountable for maintaining a continuous flow of blanks to the coin press.
Feeding Blanks to the Press
The feeding system was designed to guide the blanks one-by-one into the chamber for striking. This ensures accurate positioning of each blank for stamping.
Alignment and Positioning
In the press, the blanks should be placed precisely in the strike area so that the stamping can be completed.
Striking under High Pressure
The coin press has two dies: one stationary and one that is moving. The stationary die is the impression of the design that is negative while the moveable die is the hammer.
The die is moved and struck the blanks using a lot of force. The design is transferred onto the surface of the blank. The die's pressure creates the design, as well as the relief is raised.
Repeated Striking Optional
To create designs or images that are more sharp and more clear, several strikes may be applied on rare coins or collectible editions. Each strike increases the finer details on the surface of the blank.
Ejection and Collection
Once struck, the coins or medals that are created are taken from the press. They then are collected in trays and containers. They are inspected for quality control, to ensure that designs stamped meet all standards and criteria.
Post-Processing-
In addition to edge letters and refeding, based on the specifications for the design or mint requirements, some medals or coins will go through post-strike or other treatment.
The process of stamping under extreme pressure is essential as it imparts the desired design onto the gold blanks, turning them into finished pieces of gold ready to be used in circulation, collection or for commemoration. This process requires precision because any alterations in alignment or pressure could alter the appearance and performance of the final product.
