In the 1980s, a major transformation occurred in the printing industry with the introduction of rubber rollers. These rollers were not affected by weather conditions and offered strong resistance to corrosion. However, their high cost discouraged many small and medium enterprises (SMEs) from adopting them at the time.
Proper storage of rubber rollers is essential for maintaining their performance and longevity. Dongguan Haichang Hardware & Rubber Co., Ltd., established in 2001, has become a leading manufacturer of industrial and printing rubber rollers. With a focus on advanced technology, quality materials, and professional service, the company has built a strong reputation in the market. Their products include ink rollers, water rollers, polishing rollers, laminating rollers, gravure rollers, and more, all designed to withstand harsh environments while delivering consistent performance.
The company's core values are "customer first, quality first" and "professionalism with thoughtful service." They emphasize integrity, reliability, and innovation to meet the evolving needs of the printing industry. Their commitment to quality and customer satisfaction ensures that every product meets the highest standards.
As the printing industry continues to evolve, so do the requirements for rubber rollers. New technologies and equipment have emerged, making it crucial for businesses to keep up with the latest advancements. While some developed countries still lead in printing equipment, domestic manufacturers are steadily improving. However, when it comes to replacing printing rubber rollers, many companies find that original equipment manufacturer (OEM) parts still outperform domestic alternatives in terms of durability and performance.
In the past, printing companies often had dedicated "glue rooms" for producing rubber rollers, which led to significant pollution. As the industry modernized, older rubber rollers were gradually replaced due to their inability to handle high-speed presses. These traditional rollers struggled in extreme temperatures, leading to issues like softening in heat or hardening in cold, which affected print quality—especially in gold printing and screen printing.
Proper installation and adjustment of rubber rollers are critical for optimal performance. Technicians must ensure that the rubber roller is correctly aligned with the ink roller and printing plate. For example, in letterpress printing, the height of the rubber roller should match the typeface, while PS plates require a slightly lower height. Adjustments must be made carefully to avoid problems like uneven ink distribution or poor print quality.
During operation, the rubber roller must maintain consistent contact with the printing plate. If improperly adjusted, it can cause issues such as ink buildup, streaking, or even damage to the printing plate. Proper maintenance, including regular cleaning and storage, is also essential. After each use, the roller should be cleaned thoroughly using approved solvents like industrial alcohol. During long breaks, it’s recommended to remove the roller to prevent deformation under pressure.
To protect the surface, the roller should be wrapped in newsprint and stored in a cool, dark place. Regular maintenance, such as weekly checks, helps extend the life of the roller and ensures smooth operations. By following these practices, printing companies can maintain high-quality output and reduce downtime.
With continuous improvements in technology and a growing demand for reliable printing solutions, Dongguan Haichang remains committed to innovation and excellence in the rubber roller industry. Their dedication to quality and customer service makes them a trusted partner for businesses around the world.
Dispenser Mass Flow Meter
Sealand is a trustworthy manufacturer of CNG Dispenser Mass Flow Meter, LNG Dispenser Mass Flow Meter, LPG Dispenser Mass Flow Meter, ATEX, CE & IECEx approved.
With its high accuracy, wide rangeability and reliable performance, Sealand meter has been applied in many kinds of industries during the last 8 years. Unlike others who only focus on the measurement of liquid at normal pressure & temperature, Sealand has conquered the difficulty in the measurement under severe conditions, such as high pressure, high viscosity, high & low temperature.
Take CNG (compressed natural gas) for example. As the saying goes, the meter can measure anything else if it can measure CNG. It is quite hard to measure gas under high pressure. The sensor must be able to bear high pressure; in this way, the thickness of flow tube must be increased, so the transmitter shall be more sensitive to detect the signal; however, Sealand made it. Sealand's first model is specially designed for CNG dispenser, and now thousands of this model are put into use on the market.
Here are the pictures of Sealand Mass Flow Meter in Dispenser for your reference.
