What are the key steps in the production process of wax based carbon ribbon?

The production process of wax based carbon ribbon mainly includes the following key steps:

1、 Raw material preparation

Base film selection: The base film is the carrier of wax based carbon ribbon, and its material and thickness have a significant impact on the performance of the carbon ribbon. Common base film materials include polyester (PET), and it is necessary to choose a base film with good heat resistance, flatness, and strength.

Ink preparation: Ink is the core part of wax based carbon ribbon, composed of wax substances, resins, colorants, and additives. These ingredients need to be mixed evenly in a certain proportion to ensure the printing performance and adhesion of the ink.

2、 Coating process

Ink coating: Apply the prepared ink evenly onto one side of the base film. The coating amount needs to be precisely controlled to ensure the printing effect and wear resistance of the carbon ribbon. During the coating process, it is necessary to avoid the occurrence of defects such as white spots, patterns, or white stripes.

Back coating: Apply lubricant or heat-resistant ink on the other side of the base film to prevent wear and static electricity on the print head. This step also requires precise control of the coating amount and ensuring uniform coating.

3、 Drying and solidification

Blow cooling: The coated carbon ribbon needs to undergo blow cooling to remove solvents from the ink and preliminarily solidify the toner. This step helps prevent ink from sticking or deforming during subsequent processing.

Drying in a drying oven: After being cooled by blowing air, the carbon ribbon needs to be further dried and solidified in a drying oven to ensure that the ink is completely cured and attached to the base film. The drying temperature and time need to be precisely controlled to avoid damage to the base film or affecting the adhesion of the ink.

4、 Slitting and rewinding

Accurate cutting: According to customer requirements and printer specifications, the carbon ribbon is accurately cut into different widths. This step requires ensuring that the cutting tension and the tightness of the carbon ribbon are moderate to avoid affecting the printing effect and durability of the carbon ribbon.

Rewinding and packaging: Wrap the cut carbon ribbon onto a roll and provide appropriate packaging and protection. During the packaging process, it is necessary to ensure that the carbon ribbon is not contaminated or damaged, and is easy to store and transport.

5、 Quality control and testing

Raw material inspection: Strictly inspect raw materials before production to ensure their quality meets production requirements.

Production process monitoring: Real time monitoring and testing of each link in the production process to ensure stable and reliable product quality.

Finished product testing: Testing the wear resistance, printing effect, high temperature resistance and other properties of the wax based carbon ribbon produced to ensure that it meets customer needs and industry standards.

In summary, the production process of wax based carbon ribbon involves multiple key links, and it is necessary to strictly control the quality and process parameters of each link to ensure the performance and quality of the final product.
