Product Introduction Ink rollers are key components in the ink delivery system of a printing press. Their main function is to deliver a precise and even amount of ink to the printing plate. They are broadly classified into three types: inking rollers, transfer rollers, and impression rollers.
① Inking rollers (also known as ink fountain rollers) are used to extract a set amount of ink from the ink fountain each time (also known as ink distributing rollers).
② Transfer rollers receive this ink and distribute it evenly (also known as plate rollers).
③ Impression rollers are responsible for evenly distributing the transferred ink onto the printing plate.
The even distribution of ink ensures that the ink is transferred evenly and accurately to the printing plate, thus guaranteeing the quality of the printed product.
haobang Product Advantages 1. Materials
1) We conduct strict quality checks on all incoming raw materials. The quality of raw materials is the cornerstone of the final quality of rubber products.
2) We also strictly control the selection of raw materials, and only materials that pass a series of tests, including small-scale, medium-scale, large-scale trials, and finished product trials, are used.
2. Processes
1) Our equipment is the most advanced processing equipment.
The mixing equipment is advanced auxiliary equipment with an automatic weighing system, reducing human error. The vulcanization process uses advanced intelligent temperature-controlled vulcanization tanks, ensuring stable time, temperature, and pressure during vulcanization. The machining equipment is also the latest Shanghai machine tool, with high processing precision, improving the surface cleanliness of the rubber rollers.
2) The mixing process uses a two-stage mixing method, and the molding process uses continuous extrusion winding molding. The winding molding process has high production efficiency, can meet the needs of large-scale production, has high molding precision, and enhances product competitiveness.
3. Performance Advantages and Their Impact on Printing Quality
Performance Advantages Impact on Printing Quality High-quality raw materials, polyurethane or other rubber materials are selected according to different requirements. Selecting base materials with good elasticity, wear resistance, and corrosion resistance can adapt to high-speed printing and high-pressure working environments. Advanced continuous extrusion molding or three-roll rubber coating molding ensures the dimensions and precision of the rollers, improving the strength and durability of the rollers. Allows the printing rollers to adapt to different printing pressure requirements, ensuring even pressure on the plate during printing. Stable raw materials and continuous stable production processes ensure the quality of the rollers. Improves printing stability, extends the service life of the rollers, and reduces costs.
Performance Comparison 1. Physical Properties
1) Hardness: Our company's high-quality printing rollers offer a wider range of hardness options, allowing for customization to meet customer's specific needs. Standard hardness for printing rollers ranges from 28A to 40A, all of which we can produce;
2) Elasticity: The printing rollers produced by our company use high-quality materials and advanced manufacturing processes, resulting in excellent elasticity. A decrease in elasticity recovery ability affects the stability of the printing effect.
Index Hao Bang Printing Rollers Ordinary Commercially Available Printing Rollers Rebound Rate ≥40% ≥35% Compression Set ≤5% (70℃×24h, ISO 815B test) 8%-15% (Mid-range models generally >10%) Dynamic Response Speed Recovery within 0.02 seconds (10kHz pressure fluctuation scenario) 0.05-0.1 second recovery (high-speed printing may leave ghosting)
3) Smoothness: Our company controls different smoothness values for different parts of the printing press, resulting in a fine and even surface. Ordinary rollers are slightly lacking in smoothness uniformity and fineness, which affects the surface quality of the printed product.
2. Ink Transfer Performance
Ink Transfer
Ink Transfer Uniformity: High-quality ink rollers can transfer ink evenly to the printing plate, resulting in consistent ink color on the printed product;
Ink Transfer Amount Control: Precisely control the amount of ink transferred to ensure the printing plate receives the appropriate amount of ink;
Wear Resistance: High-quality ink rollers have good wear resistance and can maintain good ink transfer performance over extended use. Ink rollers with poor wear resistance may wear out quickly, affecting ink transfer quality and service life;
Cleanliness: Easy-to-clean ink rollers can reduce ink residue and drying on their surface, helping to maintain the stability and accuracy of ink transfer;
Maintenance Cost: Some ink rollers may require more frequent maintenance and servicing, increasing the cost of use. Ink rollers with good performance and durability can reduce maintenance costs.
