Types of Plastic Hot Stamping Machine
Hot metal stamping
The process
Hot metal stamping involves heating the metal to be stamped to a high temperature, usually over 1700 degrees Fahrenheit. The steel is then quenched in the die, resulting in a high-strength, lightweight component.
How it compares with other Plastic Hot Stamping Machine types
The most significant advantage of hot metal stamping is that it allows for the creation of complex shapes and designs. The process is also relatively fast, and the parts produced are very strong and lightweight.
Ideal applications
Unlike other stamping methods, hot metal stamping can be used to create very thin, lightweight parts. This method is often used for creating car body panels and other stamped components because it can create pieces with a high strength-to-weight ratio.
Precision metal stamping
Description of process
Precision metal stamping is a Plastic Hot Stamping Machine process that uses a lower temperature, usually around 1200 degrees Fahrenheit. The metal is not quenched in the die, so the parts produced are not as strong or lightweight as those made with hot metal stamping.
How it compares with other Plastic Hot Stamping Machine types
Precision metal stamping is quicker because there are fewer material movements between machines. Compared to other Plastic Hot Stamping Machine methods, precision stamping is more accurate and results in less waste because the metal is not quenched in the die.
Examples of and ideal applications
Precision metal stamping is a good choice for applications that require less strength, such as creating electrical components, or where speed is more important than weight, such as in the automotive industry.
Progressive Metal Stamping
Description of process
Progressive metal stamping uses multiple dies to create the desired shape. The metal is heated and then quenched in the first die. It is then moved to the next die, where it is heated and quenched again. This process is repeated until the metal has the desired shape, hence the progressive moniker.
How it compares with other Plastic Hot Stamping Machine types
Since progressive metal stamping uses multiple dies, it is slower than other Plastic Hot Stamping Machine methods. However, it is more accurate and can create parts with more complex shapes because of the numerous steps involved.
Examples of and ideal applications
Progressive metal stamping is often used for making small pieces with complex shapes, such as gears or medical components. The process is well suited for creating prototypes or low-volume runs since the multiple steps involved make it more expensive than other Plastic Hot Stamping Machine methods.
Like silk screening, Plastic Hot Stamping Machine suffers with a historic name, which refers to the origins of the process. There was a time when silk really was used to make silk screens, and there was a time when high pressure Plastic Hot Stamping Machine really was a vital part of hot stamping.
Stampingoften brings to mind large tonnage presses, burned in images, metallic dies, and ragged edged printing. High tonnage and ragged images just aren part of the modern hot stamp process. Current application methods include traditional press work along with very high quality roll-on peripheral decorating of rounds, ovals and squares in one continuous operation.
Regardless of the application machine, the benefits of hot stamping remain. It is a dry process, a very permanent and durable process. The image is thermally fused to the substrate. Even after years of outdoor exposure or complete failure and wash out of the pigment over time, a readable image often remains on the part. Hot stamping upsets the molecular structure of the material with heat and surface melting.
Hot stamping is better described as a die selective heat transfer process. The transfer only occurs where the die contacts the part. In its simplest form, hot stamping utilizes a heated die generally mounted to the upper platen of a press. The multi-layer foil is compressed between the die and a part, which is fixtured on the press work table. The foil is held sandwiched between the die and the fixtured part for a period of time known commonly as dwell time. At the completion of the dwell time, the press opens and the pigment layers of the foil have been bound to the part by heat and pressure only where the die made contact. The foil carrier is then stripped upward from the part. During the stripping operation, the pigmented layers of the foil will separate from the carrier only in the areas where heat and pressure have been applied.
Foils used in Plastic Hot Stamping Machine consist of three primary layers. In practical application most manufacturers use other layers in between the three primaries, but these are often for improved performance, weathering, and opacity. In its simple form foil is made with the layers in the opposite order that they will be on the finished part. That is, the first layer applied to the foil during manufacturing is the top layer or finish of the applied decoration. The first layer of coating, which is put on the mylar during manufacture, is what is called the release layer. It is a material which when heated will become fluid enough to allow the successive layers to be pulled off the carrier. Again, the release layer actually is the top or finish layer when the hot stamping is applied. The next layer in the foil is the color layer, this can be a vacuum metalized layer as in bright silvers and golds or a plain color in the case of pigment foils. The last layer that is applied is called the sizing, sticker, or adhesive coat. It is the layer which will actually bond to the product being printed. In particular, this layer must be compatible with the material that is being decorated.
When the foil is in contact with the part and die, heat travels from the die through the foil to the part. As the foil heats, the release layer becomes fluid, the adhesive layer is activated and sticks to the part and the color layer is carried between the two. At the correct time in the application process, the die is separated from the part, removing the heat source, then the foil is lifted off the part while the release layer is still fluid but the adhesive layer has grabbed. The color layer is stripped from the foil, trapped between the adhesive and the release, permanently bonded to the part.

The process of using the Plastic Hot Stamping Machine can be divided into the following steps
Preparation
Before starting stamping, the foil or other special material needs to be cut to the required size, the printed surface cleaned and positioned on the stamping machine.
Heating
Turn the heating system of the foil stamping machine on and wait for the hot press wheel to reach the required temperature.
Stamping
The prepared foil or other special material is placed on the printed surface and the pressure cylinder is lowered so that the pressure plate comes into contact with the hot press wheel and the required pressure is applied. Within a certain period of time, the foil or other special material forms a stamping effect with the surface of the print.
Cooling
After the stamping has been completed, it is necessary to wait for the printed surface to cool completely before it can be removed.
Maintenance
After using the foil stamping machine for a period of time, it needs to be maintained, including cleaning the hot press wheel and replacing the heating tube.
The structure of the Plastic Hot Stamping Machine consists of the following main parts
Pressure part
The hot stamping machine needs to transfer the metal foil or thermal material to the surface of the object through pressure, so the pressure part is the core component of the hot stamping machine, it consists of pressure mechanism, air pressure system, electromagnetic clutch and other parts.
Stamping head part
The stamping head is the printing part of the stamping machine and is usually composed of the stamping head, transmission part, heating system, etc. The heating system of the stamping head is usually composed of the heating body, temperature control system, heat dissipation system and other parts.
Control system
The control system of the hot stamping machine is usually composed of computer control, touch screen control and other parts, which can complete the automatic control and adjustment of the hot stamping machine.
There are five ingredients need to get started in Plastic Hot Stamping Machine
1. A product to stamp. Products that Plastic Hot Stamping Machine very well are usually designed that way right from concept. Decorating should always be considered in any initial part design.
2. Artwork and die. Consult with a die maker or hot stamp machinery manufacturer about your artwork unless you have a lot of experience. There are minimum element sizes, some especially difficult patterns and some guidelines for type spacing and blocking that if modified before the first print can save you a lot of trouble later.
3. Foil which is the color you desire and which is compatible with the product you want to stamp. Foil is available in virtually any color and sheen from matte to bright metallic silvers and gold along with special effects like holograms, opalescents, and continuous patterns. Regardless of the color of foil you select, it must be compatible with the substrate you intend to stamp. Foil manufacturers make different formulations for PET, PP, PE, Wood, Paper, and many others.
4. A fixture or nest to hold the part during the stamping cycle. The most important aspect of a nesting fixture is that it provides full intimate contact and rigid support underneath the print area and prevents part shifting as the die contacts, dwells on, and leaves the part.
5. A machine to bring it all together. Plastic Hot Stamping Machine today range from hand lever operated machines, pneumatic direct acting machines, pneumatic and hydraulic hybrids, a variety of pneumatic and mechanical toggle and wedge approaches, and most recently all electronic servo driven presses and multi-axis decorating centers. Selecting the correct machine for the job may be influenced by the quantity of the first job you have to run and other products that you may consider using the machine for in the future.
