What are the steps of the production process of wax-based carbon strips?

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

First, raw material preparation

Base film selection: Select the appropriate plastic film as the substrate, which is the base support layer of the wax-based carbon strip. The quality and properties of the base film directly affect the overall quality of the carbon strip.

Ink formula: According to product requirements, the preparation of wax substances, resins, additives and colorants composed of heat transfer ink. The ratio of these components needs to be precisely controlled to ensure the performance and printing effect of the ink.

Second, ink production and coating

Ink production: wax substances and resins are fully mixed and uniform under the condition of heating and melting, and then the basket mill or other grinding equipment is used to fully mix them with colorants and additives to make thermal transfer ink.

Coating process: The heat transfer ink is evenly coated on one side of the base film, and the coating amount needs to be precisely controlled, usually between 2.2-3.5 grams per square. In the coating process, it is necessary to ensure that the ink layer is uniform, no white spots, no texture defects.

Third, heat-resistant ink coating (optional)

According to product requirements, it is sometimes necessary to coat the other side of the base film with a heat-resistant ink layer to improve the high temperature resistance and printing effect of the carbon strip. The coating amount of heat-resistant ink layer is usually less, about 0.1-1 grams per square.

Fourth, cutting and rewinding

Slitting: Use slitting and rewinding machine to slitting the coated carbon strip according to a specific width. The cutting tension and tightness of the carbon strip should be precisely mastered during the sashing process to ensure the performance and printing effect of the carbon strip roll.

Rewinding: The cut carbon tape is wound on the reel to form a finished carbon tape roll. During the rewinding process, pay attention to the tightness and appearance quality of the carbon tape roll.

Fifth, quality control and testing

Quality control: In the entire production process, it is necessary to carry out strict quality control of raw materials and finished products, including appearance inspection, size measurement, performance testing, etc.

Performance testing: A series of performance tests are carried out on the finished carbon strip, such as wear resistance, printing effect, high temperature resistance, aging resistance, etc., to ensure that the carbon strip meets product specifications and customer needs.

Sixth, packaging and marking

Packaging: The finished carbon strip is packaged in a certain amount to prevent damage during transportation and storage.

Label: Clearly mark the model, specification, production date, shelf life and other information of the carbon belt on the package to ensure the traceability of the product.

Through the above steps, wax-based carbon strips can be produced to meet the needs of various application scenarios. With the continuous progress of technology and the change of market demand, the production process of wax-based carbon strip is also constantly optimized and improved.
