Coin Rimming Machine
Premium Chinese Supplier for Professional Gold Coin Production Solutions
The coin rimming machine is used for rolling the edges of various sizes of gold, silver, copper, platinum and other coin blanks before pressing coins. The machine forms an arc with a uniform diameter by extruding and rolling. The use of this step can well avoid the generation of gold coin edge capes and burrs, thereby saving subsequent processing steps and making the finished product smoother.
SuperbMelt has developed semi-automatic and fully automatic styles for manufacturers with different output and sizes. The fully automatic output machine has higher efficiency and is suitable for medium and large coin making factory, while the semi-automatic is suitable for smaller factories, which can greatly reduce costs while saving production time.

Full-automatic Rimming Machine
High Efficient
The machine adopts full automatic operation, including feeding device, rolling disc, etc. Only the coin blank needs to be put into the feeding barrel, and the machine can run the whole process by itself after setting the speed and time, which saves time and labor.
Multiple Sizes
One disc of the fully automated device can customize three sizes of the track, which means a machine can roll gold coins with three diameter sizes. By adjusting the auxiliary mould, the size of the arc angle of the finished product can be changed, so that the whole mould does not need to be replaced, and the use is more convenient.
Fast
The fully automatic edging machine can achieve one step in finish. When the coins roll over, the trimming can be completed, and there is no need to roll repeatedly. Therefore, it is faster, and it only takes 1 second for each coin to complete the edging.
Automatic Feeding Device
The equipment cooperates with the automatic frequency modulation vibration disc to realize automatic feeding and glue spraying treatment on the surface of the vibration disc to avoid surface scratches.
Semi-automatic Rimming Machine
Compact
Semi-automatic coin reeding machines are small and do not occupy factory locations, which can save a lot of space.
Custom Edge
The edge shape can be customized, and the edge making of other shapes can be realized by changing the mold.
Low Cost
Cost-effective, suitable for small and medium-sized coin factories or large factories with more staffing.
Fine Workmanship
Semi-automatic edge rolling machine is manually discharged, and the workmanship can be more refined. It is suitable for precious metal coin making factories
In order to make each gold coin have a uniform diameter and a smooth edge, the use of an edging machine before pressing the coin can make the finished product of higher quality and avoid subsequent complicated processing.
Coin upsetting mill is used for making various metals, including gold, silver, copper, platinum and other metal coins. It is suitable for rolling the edges of various types of coins, such as game coins, circulating currencies, commemorative coins, medals and so on.
Because of this process of rolling edges, when the hydraulic press presses gold coins, it will not extrude excess burrs and capes because the coin blank has no arc. thereby saving the follow-up processing and avoiding the waste of raw materials caused by the problem of gold coins.

Why SuperbMelt Coin Rimming Machine
Any Question About SuperbMelt Coin Rimming Machine
Guide of SuperbMelt Coin Rimming Machine
SuperbMelt Why Is it Necessary to Toll the Gold Coins Edge?
The round blank of the gold coin was originally obtained by cutting a whole piece of metal, so although the untreated coin is obviously round, it can still be seen that the edge of the gold coin, that is, the third side is still at a right angle.
When using a hydraulic press to make gold coins, you need to match a set of gold coin molds, and the ring in the middle determines the final gold coin size.
The upsetting mill can make the original right-angled edge have an arc, so that a certain gap is created between the gold coin and the mold, and then the entire coin can just fill the mold at the moment of pressing, so that a perfect coin can be obtained without extra burrs.
What Shape Can be Achieved of The Edge Through the Coin Edge Roller?
The shapes on the edges of coins can vary depending on the roller mold.
The edging machine can realize the edges of gold coins in various shapes, and can be made into arc shapes, flat shapes or convex shapes by changing the mold.
Some common shapes include reeded (grooved), lettered (inscribed with lettering), milled (smooth and flat), or plain (no edge design). The edge design is often an important security feature and can help to prevent counterfeiting.
How do I Choose Semi-auto and Automatic Coin Rimming Machine?
When choosing between a semi-auto and automatic coin rimming machine, you should consider the following factors:
1. Volume
Production volume is a priority, If you need to rim a large volume of coins,Like some big factories that need to produce 3-50,000 gold coins a day, an automatic machine is more efficient and faster.
If you need to rim only a small number of coins, For example, many small and medium-sized coin factories produce less than 5,000 a day, a semi-auto machine may be more suitable.
2. Precision
In terms of accuracy, both machines can achieve accurate sizes, manual discharging can be more precise, and it is more suitable for some precious metal banknotes.
3. Cost
In terms of cost, Automatic machines are generally more expensive than semi-auto machines.
Semi-automatic cost performance is higher, the machine is simple, maintenance is easier, and maintenance costs are relatively reduced.
4. Space
Automatic machines are larger and require more space than semi-auto machines.
Semi-automatic machines are compact and can be used on the desktop.
5. Skill level
If you are experienced in using semi-auto machines, a semi-auto machine may be a better option for you. However, if you are new to coin rimming, an automatic machine is easier to use.
6. Finished Dimension
The gold coin size of both machines can be customized, semi-automatic can achieve 15-50 mm, suitable for most coins, and the fully automatic size can be customized 15-100 mm to use some large gold medals and commemorative coins.
Ultimately, the choice between a semi-auto and automatic coin rimming machine will depend on your specific needs and preferences.
