Hot Ink Roller

A hot ink coder machine, also known as a hot stamp coder or a hot foil printer, is a printing device that uses heat and pressure to transfer ink onto a surface. It is commonly used for printing batch numbers, expiration dates, and other variable information on packaging materials such as plastic films, foils, and paper.

The hot ink coder machine typically consists of a printing head, a heated printing plate, an ink roll, and a control system. The printing head contains a set of characters or symbols that are mounted on metal type holders, which can be heated and pressed against the printing plate. The ink roll, which is heated and rotated by a motor, picks up ink from a reservoir and transfers it onto the printing plate.

When the printing head is pressed against the printing plate, the heated metal type holders transfer the ink onto the surface of the packaging material. The ink dries quickly and forms a permanent mark, which can withstand handling, transportation, and storage.

Hot ink coder machines are widely used in the food, beverage, pharmaceutical, and cosmetic industries to ensure the safety and quality of their products by providing accurate and legible product information. They are known for their reliability, speed, and ease of use, and can print up to 300 prints per minute, depending on the size and complexity of the design.
