In the 1980s, a major transformation took place in the printing industry with the introduction of rubber rollers. These new rollers were not affected by weather conditions and offered strong durability and resistance to corrosion. However, their high cost made them less accessible to small and medium-sized enterprises (SMEs). Despite this, as the economy grew, these rubber rollers became widely accepted by the majority of users due to their reliability and performance.
Dongguan Haichang Hardware & Rubber Co., Ltd., established in 2001, is a leading manufacturer of industrial and printing machinery rubber rollers. The company has built its reputation on advanced technology, skilled personnel, and a commitment to quality. With a focus on integrity and precision, it has steadily expanded its market share and gained the trust of customers across various industries.
The company produces a wide range of rubber rollers, including ink rollers, water rollers, alcohol-water rollers, polishing rollers, oil rollers, paper rollers, laminating rollers, film blowing rollers, gravure rollers, offset rollers, and more. These products are known for their excellent resistance to corrosion, acid, alkali, wear, and oil, as well as their ability to withstand tearing, high temperatures, moisture, static, and dirt. Their elasticity and long-lasting performance make them ideal for applications such as color printing, carton printing, and plastic bag printing.
Haichang adheres to a customer-centric philosophy, prioritizing quality and service. The company's policies emphasize professionalism, thoughtful service, and sincerity in business. It continues to invest in advanced equipment and professional design to ensure that every customer receives reliable and timely support.
As the printing industry evolves, new technologies and materials have emerged, driving the need for more efficient and durable components. While some developed countries still lead in printing equipment, domestic manufacturers like Haichang are rapidly improving, offering competitive alternatives that meet modern production demands.
Printing rubber rollers must be carefully selected and maintained to ensure optimal performance. In the past, traditional rubber rollers were often inadequate for high-speed presses, especially in environments with extreme temperatures or humidity. This led to issues such as softening, hardening, and poor print quality—particularly in gold printing and screen printing.
Proper installation and adjustment of printing rubber rollers are essential. Technicians must ensure that the roller makes proper contact with the ink roller and the printing plate. Adjustments should be made based on the specific requirements of the job. For example, when printing solid colors, the roller can be slightly lowered within a ±0.5 mm tolerance to ensure even ink distribution.
Improper use or hasty adjustments can lead to serious problems, such as damage to the roller surface, uneven ink application, or even equipment failure. Therefore, following correct procedures is crucial to maintaining print quality and prolonging the life of the rollers.
Regular maintenance is also vital. After each day’s operation, the rubber roller should be thoroughly cleaned using appropriate solvents like industrial alcohol. During holidays, the roller should be removed to prevent deformation under pressure. The surface should be protected by wrapping it in newsprint and storing it in a dark, cool place.
By following these best practices, printing companies can maximize the efficiency and lifespan of their rubber rollers, ensuring consistent and high-quality results. With continuous innovation and a dedication to excellence, Dongguan Haichang remains a trusted partner in the printing industry.
