Printing rubber rollers are essential components in the printing industry, and their proper installation, adjustment, and maintenance are crucial for achieving high-quality results. Whether you're using letterpress, gravure, flexo, or offset printing, understanding how to install and commission these rollers correctly is vital. Improper handling can lead to poor print quality, damage to the roller, and even shortened lifespan of the printing plate.
Proper installation involves ensuring that the rubber roller is in close contact with both the ink roller and the printing plate. For example, the height of a letterpress is typically 3.14mm, matching the type height, while a PS plate is lower at around 1.2mm. Adjustments must be made accordingly during installation. Additionally, it's important to ensure all bearings and shaft seats are well lubricated. Applying oil to the outer surface of the rubber bearings and sleeves before installation helps reduce friction and prolongs the life of the roller.
When it comes to debugging the printing rubber roller, pressure adjustment is a key step. Too little pressure may result in poor ink and water transfer, while excessive pressure can cause overheating, expansion, and premature aging of the rubber. This not only affects print quality but also increases the risk of damage. If alcohol-based dampening solutions are used, extra care must be taken to avoid reducing the roller’s lifespan due to improper transmission.
For printed products with a base color, the rubber roller should be adjusted within a ±0.5mm range to ensure even ink distribution. When printing text, the roller height should be slightly lower than the type height to prevent excessive wear and maintain clarity. Using an adjustment roller before finalizing the settings allows operators to fine-tune the height accurately, ensuring consistent performance during high-speed printing.
If adjustments are rushed or neglected, several issues may arise: surface damage to the roller, ink smearing, uneven ink coverage, or even mechanical failure due to excessive tension between rollers. These problems not only affect print quality but also result in costly repairs and downtime.
In summary, the correct installation, adjustment, and maintenance of printing rubber rollers are essential for achieving optimal performance and longevity. At Dongguan Haichang, we understand the importance of these processes and are committed to providing reliable, high-quality solutions to our clients.

In Wall Bidet Frame
The In-Wall Bidet Frame is a sturdy iron frame specifically designed to provide support for wall-mounted bidets. By fitting into the wall, it effectively conceals the bidet's tank and plumbing, resulting in a modern and streamlined appearance for the bathroom.
Beyond its aesthetic advantages, the in-wall bidet frame offers several functional benefits. One of its primary advantages is the enhanced support it provides for the bidet fixture. This is particularly beneficial for larger individuals or those with limited mobility, as the frame ensures a stable and secure installation. The added support contributes to a comfortable and safe user experience.
The in-wall bidet frame is also height adjustable, allowing for customization to accommodate individual preferences and needs. This feature ensures that users can set the bidet at a comfortable height, promoting optimal usability and convenience.
Moreover, the space-saving design of the in-wall bidet frame is highly advantageous, especially in smaller bathrooms where floor space is limited. By fitting into the wall, the frame eliminates the need for additional floor space, effectively maximizing the available area. This can be particularly valuable for compact bathrooms, as it allows for a more efficient utilization of the available space.
In addition to space-saving benefits, the design of the in-wall bidet frame also facilitates easier cleaning and maintenance. With fewer exposed areas and nooks, there are fewer spaces for dust and grime to accumulate. This simplifies the cleaning process and helps maintain a hygienic environment.
