  Working Principle

• Pressure generation and conversion part: This high-performance hot stamping machine uses a hydraulic conversion cylinder to provide the pressure required for hot stamping. The hydraulic oil enters the hydraulic system driven by the oil pump, and transmits the oil pressure to the conversion cylinder through related valves, pipelines and other components. The conversion cylinder uses the oil pressure to generate a large and stable pressure, and converts it into a mechanical force suitable for hot stamping operations to drive the hot stamping parts to work.

• Workbench part: The curved workbench is specially designed for curved objects such as plastic hoses, plastic cups, and cylindrical cosmetics. Its shape can fit the curved surfaces of these objects well. When hot stamping, the object to be hot stamped is placed on the workbench. The curved workbench can fix the object and cooperate with its own rotation or translation (possibly driven by a motor, etc.) so that the entire curved surface of the object can be evenly in contact with the hot stamping parts, ensuring the comprehensiveness and uniformity of hot stamping.

• Hot stamping process: Place the hot stamping foil on the surface of plastic hoses, plastic cups, cylindrical cosmetics, etc., and heat the hot stamping plate to a suitable temperature through a heating device. Afterwards, under the pressure provided by the hydraulic conversion cylinder, the hot stamping plate fits tightly with the curved surface of the object, and the high temperature transfers the metal coating on the hot stamping foil to the surface of the object, completing the hot stamping operation.

Application scenarios

• Cosmetics industry: Hot stamping of cylindrical cosmetic packaging (such as lipstick tubes, hand cream tubes, etc.) can highlight brand logos, product names, decorative patterns and other elements, improve the appearance of the product, enhance its recognition and appeal in the market, and meet the requirements of cosmetics as fashionable consumer products for packaging beauty.

• Daily necessities: Hot stamping on plastic cups can be printed with personalized patterns, texts, etc., such as commemorative cups and gift cups, which can add unique commemorative significance through hot stamping; plastic hoses (such as packaging tubes of some cleaning products) can also be beautified and branded through hot stamping to make them more distinctive.

Advantages

• Adaptable to curved objects: The curved workbench with the hydraulic conversion cylinder can effectively solve the problem of hot stamping of curved objects such as plastic hoses, plastic cups, and cylindrical cosmetics. It can ensure that all parts of the curved surface can obtain high-quality hot stamping effects, with clear and firm patterns, and enhance the overall beauty of the product.

• High-performance and stable pressure: The pressure provided by the hydraulic conversion cylinder is stable and large, ensuring that the hot stamping plate and the curved surface of the object fit closely during the hot stamping process, reducing hot stamping defects caused by insufficient or unstable pressure, and ensuring the consistency of hot stamping quality.

• Good hot stamping effect: The overall structure and working method enable the hot stamping machine to present high-quality hot stamping effects when hot stamping such curved plastic products, which helps to increase the added value of the product and meet the high requirements of related industries for the aesthetics of product packaging.
