The company has evolved from producing basic cutting machines into a modern enterprise offering complete machines, parts, quality control, and comprehensive after-sales support.
One common issue encountered during the printing process is print adhesion, which can significantly affect product quality and efficiency. This problem often occurs due to several factors. First, if the stacked printed bags are too heavy, they may stick together during the printing or rewinding stages. Second, excessive printing speed can create high tension, leading to tight rewinding and subsequent adhesion. Third, improper adjustment of the drying device or mechanical malfunctions can result in uneven ink drying. Fourth, slow ink drying or poor drying performance can also cause sticking. Additionally, high ambient temperatures that prevent proper cooling or the use of non-heat-resistant inks may contribute to this issue. Lastly, excessive ink bleeding through the back of the material can lead to adhesion problems.
To resolve these issues, it's important to manage the stacking height of printed products to avoid excessive weight and pressure on the lower layers. Adjusting the printing speed and controlling the tension during rewinding can help maintain consistent and smooth operation. It's also crucial to check the drying system and ensure the drying angle is correctly set for optimal ink drying. Improving the ink's drying properties by adding viscosity enhancers or using low-molecular-weight solvents with high evaporation rates can be effective. In some cases, special diluents from the ink manufacturer—such as a mixture of 90% ethyl ester and 10% ethanol—can be used to enhance drying performance.
Maintaining a stable and cool working environment is essential. Reducing workshop or warehouse temperatures by ventilating or using air conditioning can prevent overheating. Using heat-resistant inks is also recommended to minimize adhesion risks. By addressing these factors, companies can significantly reduce print adhesion issues and improve overall production quality.

Crane Sole Plate is used under crane rail. The primary function of soleplates is to provide rails with a flat and smooth resting surface. Soleplates are used to support the rails in situations where concrete is not strong enough to support crane rails. Depending on the load and the type of rail, soleplates can be made continuous or individual.
