1. Structural features

• Cantilever structure: For this type of hydraulic hot stamping machine, the cantilever part is used to install hot stamping components, including hot stamping plates. The cantilever design makes the operating space more flexible and convenient for placing and removing plastic frames such as beer frames and beverage frames of different sizes. It can effectively avoid being blocked by other components during the loading and unloading of frames, and improve work efficiency.

• Hydraulic system: It is the power core of the machine. It is mainly composed of hydraulic pumps, hydraulic cylinders, hydraulic valves, etc. The hydraulic pump provides power to deliver hydraulic oil to the hydraulic cylinder. The hydraulic cylinder generates strong pressure through the movement of the piston, which is used to achieve pressure control during the hot stamping process. The hydraulic valve is used to adjust the flow and direction of the hydraulic oil, thereby accurately controlling the hot stamping pressure and speed. This hydraulic system can generate stable and large pressure to ensure that the hot stamping pattern is firmly attached to the plastic frame.

• Hot stamping components: including hot stamping plates and heating devices. The material of the hot stamping plate is usually a metal with good thermal conductivity, such as copper alloys. Its surface is finely processed to ensure the flatness and clarity of the hot stamping pattern. The heating device is used to heat the hot stamping plate to a suitable temperature, generally through electric heating, and has a temperature control system, which can accurately control the hot stamping temperature to meet the requirements of different plastic materials and hot stamping foils.

2. Working principle

• First, place the plastic frames such as beer frames and beverage frames that need hot stamping on the workbench of the hot stamping machine. After starting the machine, the hydraulic system starts to work, and the hydraulic cylinder pushes the cantilever to lower the hot stamping plate. During the descent process, the heating device has heated the hot stamping plate to a predetermined temperature. When the hot stamping plate contacts the hot stamping foil placed on the plastic frame and the surface of the plastic frame, the metal layer or pattern on the hot stamping foil will be transferred to the surface of the plastic frame under the pressure applied by the hydraulic system. After a certain period of time (this time depends on factors such as plastic material and hot stamping pattern), the hydraulic system controls the hot stamping plate to rise and completes a hot stamping operation.

3. Scope of application

• Mainly suitable for hot stamping of various food plastic frames, such as beer frames, beverage frames, soda frames, yogurt frames, etc. These plastic frames are generally made of plastics such as PP (polypropylene) and PE (polyethylene). This hot stamping machine can stamp brand logos, patterns, production dates and other information on the surface of plastic frames, which can beautify product packaging and improve brand recognition.

4. Operation process

• Preparation: Check whether the oil level of the hydraulic system is normal and ensure that the hydraulic pump, hydraulic cylinder and other components are working properly. Install a suitable hot stamping plate and set parameters such as heating temperature and hot stamping pressure according to the material and hot stamping requirements of the plastic frame. Place the hot stamping foil on the position of the plastic frame where hot stamping is required.

• Place plastic frame: Place plastic frames such as beer frames and beverage frames steadily on the workbench of the hot stamping machine to ensure accurate positioning for easy hot stamping.

• Hot stamping operation: Start the hot stamping machine and observe the working status of the hydraulic system and heating device. When the hot stamping plate descends and contacts the plastic frame, maintain a certain pressure and time to complete the hot stamping process. During the hot stamping process, pay attention to the hot stamping effect and adjust the parameters in time if there is any problem.

• Take out the plastic frame: After the hot stamping is completed, wait for the hot stamping plate to rise, take out the hot stamped plastic frame from the workbench, and check the hot stamping quality. If you need to hot stamp the next plastic frame, repeat the above steps.
