What are the production steps of all resin carbon strip?

The production steps of all-resin carbon strip mainly include the following links:

First, raw material preparation

Base film selection: High-quality polyester (PET) film is usually selected as the base film because of its excellent mechanical strength and thermal stability. The choice of base film is crucial to the performance of the final carbon strip.

Preparation of resins and additives: Preparation of resin-based materials for coating, as well as necessary additives such as pigments, waxes and various additives to improve the physical and chemical properties of toner.

Second, coating process

Ink production: The processing of resin-based materials may require careful grinding to ensure their quality.

Coating operation: Coating one or more layers of ink on the base film. This step needs to be carried out in a controlled environment to ensure that the toner layer is uniform, no white spots, no stripes, and no white strips.

Back coat coating: A lubricant is applied to the other side of the base film to prevent wear of the print head and prevent static electricity.

Third, drying and curing

Drying process: The coated carbon strip undergoes a series of drying processes to remove solvents and solidify the toner.

Heat curing treatment (for some specific processes) : In some production processes, it may also be necessary to heat cure the carbon strip in a high temperature oven to completely cure the resin and form a hardened resin matrix.

Fourth, cutting and winding

Cutting: The carbon strip is cut into different widths using a slitting and winder to meet the needs of different printers. This step requires a precise grasp of the cutting tension and tightness of the carbon strip to ensure the quality of the final carbon strip.

Winding: The cut carbon tape is wound onto the drum for easy storage and transportation.

Fifth, quality control and testing

Quality control: In the entire production process, the raw materials and finished products are strictly controlled to ensure that the quality of the carbon strip meets the standard.

Performance test: A series of tests and inspections are carried out on the carbon belt, including wear resistance, printing effect, high temperature resistance and other performance tests to ensure that the carbon belt can meet the needs of different users.

Sixth, packaging and identification

Packaging: In order to ensure good printing results, thermal transfer carbon tape products must be able to provide adequate protection for the product during packaging.

Identification: Clear identification to ensure traceability.

These steps together form the production process of the all-resin carbon strip. In actual production, it may also be necessary to make certain adjustments and optimization according to specific needs and equipment conditions.
