What are the key steps in the production process of color all-resin carbon strips?

The production process of colored all-resin carbon strips involves several key steps that together ensure a high quality production of carbon strips. The following are the main key steps in the production of colored all-resin carbon strips:

1. Raw material preparation

Base film selection: Polyester (PET) film is usually chosen as the base film because it has excellent mechanical strength and thermal stability, which is crucial to the performance of the final carbon strip.

Ink preparation: The ink is composed of resin, pigment powder, wax and various additives mixed in a certain proportion. Among them, the resin and wax ensure that the toner can be correctly transferred and attached to the medium when heated, and the additives are used to improve the various physical and chemical properties of the toner, such as wear resistance and solvent resistance.

2. Coating process

Ink coating: In a controlled environment, the prepared ink is evenly coated on the PET base film. This step needs to ensure that the ink layer is uniform, no white spots, no stripes, no white strips.

Multi-layer coating: For colored all-resin carbon strips, it may be necessary to apply multiple layers of different colors of ink to achieve the desired color effect. The coating of each layer of ink requires precise control to ensure accurate color and strong bonding between layers.

3. Drying and curing

Drying process: The coated carbon strip undergoes a series of drying processes to remove solvents and solidify the toner. This step is essential to improve the adhesion and wear resistance of the carbon strip.

Temperature control: The temperature needs to be strictly controlled during the drying process to ensure that the toner can cure evenly without affecting the performance of the carbon strip.

4. Winding and cutting

Winding: The dried and cured carbon tape is wound onto a drum for easy storage and transportation.

Cutting: According to demand, the wound carbon tape is cut into different widths to meet the needs of different types of printers. When cutting, it is necessary to accurately grasp the cutting tension and the tightness of the carbon strip to ensure the quality of the carbon strip.

5. Inspection and packaging

Inspection: The appearance and performance of the finished color resin carbon strip are tested, including color accuracy, adhesion, wear resistance, etc.

Packaging: Qualified carbon strips will be packaged to prevent damage during storage and transportation. The packaging needs to clearly identify the relevant information of the product, such as model, specification, production date, etc., to ensure traceability.

6. Special Treatment (if applicable)

For some color all-resin carbon strips with special needs, additional processing steps may also be required, such as release coating, back coating, etc., to improve the special properties of the carbon strip or to adapt to specific application scenarios.

In summary, the production process of color all-resin carbon strip is a complex and fine process, which requires strict control of parameters and conditions of each link to ensure the production of high-quality carbon strip products.
