I. Plate-shaped Rubber Products: Focusing on the Production of "Large-area, High Uniformity, and Functional Composite"

1. Industrial and Special Rubber Sheets

• Application Scenarios: Including chemical anti-corrosion rubber sheets (such as anti-corrosion layers for floors in electroplating workshops), food-grade wear-resistant rubber sheets (such as anti-slip pads for operating tables in slaughterhouses), and high-temperature-resistant silicone rubber sheets (such as liners for ovens in electronics factories).
  
  
• Technical Adaptability: Through high-precision sheeting of raw materials like natural rubber, nitrile rubber, and silicone rubber by calenders (thickness range 0.5-50mm, deviation ≤0.03mm), combined with single-sided/double-sided continuous rubberizing technology for textiles (canvas, fiberglass cloth), the tear resistance of rubber sheets can be enhanced (tensile strength increased by over 30%). For example, chemical anti-corrosion rubber sheets require an acid and alkali-resistant rubber layer attached to the base layer. The equipment ensures instant bonding between the rubber layer and the base material without bubbles by synchronously controlling the temperature (120-180℃) and pressure of the calender rolls, avoiding delamination caused by chemical penetration.
  
  
• Core Advantages: Compared with traditional molding processes, continuous calendering can realize one-time molding of rubber sheets over 100 meters long, significantly reducing splicing loss (material utilization rate increased from 70% to over 95%).
  
  

2. Thin Conveyor Belts and Printing Blankets

• Thin Conveyor Belts: Suitable for light material conveying (such as cosmetic production lines and pharmaceutical packaging lines), adopting a "polyester cord fabric + rubber layer" composite structure. The equipment realizes instant curing of the cord fabric and rubber material through continuous rubberizing technology, with the rubber layer thickness controlled at 0.3-1mm, ensuring the conveyor belt is thin yet tough (tensile strength up to 15MPa). Its surface smoothness (Ra ≤0.8μm) meets food-grade hygiene standards (compliant with FDA 21 CFR 177.2600).
  
  
• Printing Blankets: As core consumables for printing presses, they need to have high elasticity and dimensional stability. The equipment performs multi-layer composite calendering of nitrile rubber and nylon base cloth through calenders, precisely controlling the thickness ratio of each layer (rubber layer: base cloth = 1:2), ensuring the blanket does not stretch or deform during high-speed printing (30,000 sheets/hour), suitable for high-precision printing of books and packaging.
  
  

3. Waterproof Materials and Rubber-plastic Flooring

• Waterproof Materials: Such as roof waterproofing membranes (composite of rubber and polyester non-woven fabric) and tunnel water-stop plates. The equipment realizes one-time compounding of rubber layers (such as EPDM rubber) and reinforcing cloth through double-sided continuous rubberizing technology. The rubber layer density reaches over 1.2g/cm³, ensuring water impermeability (no leakage under 0.3MPa pressure for 30 minutes), and its low-temperature flexibility (-30℃ without cracks) is suitable for cold regions in northern China.
  
  
• Rubber-plastic Flooring: Wear-resistant and anti-slip flooring used in shopping malls, hospitals, etc., adopting calendered compounding of "PVC rubber material + fiberglass felt." The equipment can simultaneously complete rubber material coloring, embossing (such as wood grain, marble grain imitation), and base material bonding, with a production speed of 20 meters/minute. By controlling the calendering temperature (160-180℃), the thermal shrinkage rate of the flooring is ensured to be ≤0.5%, avoiding arching after installation.
  
  

4. Liners and Functional Plates

• Industrial Liners: Such as anti-corrosion liners for storage tanks (butyl rubber sheets) and wear-resistant liners for centrifuge drums (neoprene rubber sheets). The high-precision thickness control of calenders (deviation ≤0.02mm) ensures perfect bonding between the liner and the inner wall of the equipment, reducing gaps for medium penetration; the continuous production mode can meet the demand for integral liners of large storage tanks (with a diameter of over 10 meters), avoiding corrosion risks caused by splicing gaps.
  
  
• Sound Insulation and Shock Absorption Plates: Rubber sound insulation plates (composite of rubber and sound-absorbing cotton) used in buildings and automobiles. The equipment realizes close bonding between the rubber layer and sound-absorbing materials through rubberizing technology, and the uniformity of the rubber layer ensures stable sound insulation (≥25dB), suitable for noise reduction in residential elevator shafts and automobile engine compartments.
  
  
  

II. Special-shaped/Strip Rubber Products: Overcoming Production Difficulties of "Seamless, High Precision, and Complex Structure"

1. Seamless Circular Belts and Transmission Belts

• Application Scenarios: Food conveying circular belts (such as biscuit production lines), synchronous belts for textile machinery, and base belts for sander sanding belts.
  
  
• Technical Breakthrough: Traditional circular belts are mostly spliced with joints, which are prone to breakage during high-speed operation. Our equipment realizes one-time molding of seamless circular belts through a "continuous extrusion-calendering-vulcanization integration" process: first, the rubber material and cord fabric base layer are calendered and compounded, then continuously vulcanized through a circular mold, ensuring the perimeter deviation of the belt body is ≤1mm, and the joint strength is consistent with the main body (breaking strength ≥18MPa), suitable for industrial production lines operating continuously for 24 hours.
  
  

2. Rubber Sealing Strips and Profiles

• Sealing Strips: Including automotive door and window sealing strips (EPDM material) and container door frame sealing strips (composite of EPDM and foam rubber). The equipment can produce sealing strips with complex cross-sections (such as structures with flocking layers and steel core skeletons) through "multi-roll calendering + extrusion compounding" technology, with dimensional accuracy (cross-sectional deviation ≤0.1mm) ensuring a perfect fit with the assembly groove, and flocking adhesion (≥5N/25mm) avoiding falling off during assembly.
  
  
• Profiles: Such as cable protective sleeves (neoprene) and fitness equipment handle sleeves (foam rubber). The equipment supports co-extrusion calendering of multiple rubber materials (such as hard rubber + soft rubber composite), enabling one-time molding of complex cross-sections like "T-type," "L-type," and "hollow type," with production efficiency increased by 50% compared to traditional molding, and online inspection systems to eliminate products with dimensional deviations.
  
  
  

3. Rubber Hoses and Fluid Conveying Accessories

• Industrial Hoses: Such as oil-resistant hoses (nitrile rubber inner layer + canvas reinforcement layer) and food-grade silicone hoses (used for dairy product conveying). The equipment adopts a "continuous process of inner rubber calendering - reinforcement layer braiding - outer rubber bonding," ensuring the inner diameter tolerance of the hose (≤0.2mm) and pressure resistance (working pressure 1-10MPa). Moreover, the production of silicone hoses can meet USP Class VI medical certification, suitable for clean conveying in pharmaceutical and food industries.
  
  
• High-pressure Hose Joints: The sealing rubber rings for hose joints are produced by calenders, with high-precision dimensional control (diameter deviation ≤0.05mm) ensuring a tight fit with metal joints, avoiding high-pressure fluid leakage (such as hoses in hydraulic systems).
  
  

4. Water-stop Belts and Engineering Seals

• Water-stop Belts: Rubber water-stop belts (natural rubber + cord fabric reinforcement) used in water conservancy projects (such as dams and tunnels). The equipment embeds cord fabric into the rubber belt body through continuous rubberizing technology, forming water-stop structures such as "central holes" and "ribs." The peel strength between the rubber layer and the fabric layer is ≥3kN/m, ensuring no delamination under water pressure, suitable for high water pressure scenarios with a water head of over 100 meters.
  
  
• Engineering Seals: Such as building expansion joint sealing strips (neoprene) and bridge bearing dust covers (EPDM rubber). The calendering process can realize one-time molding of fine structures such as "lips" and "grooves" of seals, with dimensional stability (dimensional change rate ≤3% after thermal aging) meeting the requirements of long-term outdoor use.
  
  
  

III. Technical Empowerment: Creating Three Core Values for the Rubber Products Industry

1. Efficiency Revolution: The continuous production mode increases the daily output of plate-shaped products to 2-3 times that of traditional processes (e.g., rubber-plastic flooring can reach 10,000㎡ per day), and the mold change time for special-shaped products is shortened to within 30 minutes, adapting to the demand for "multi-variety, large-batch" orders.
   
   
2. Quality Upgrade: High-precision calendering (thickness deviation ≤0.02mm) and rubberizing (rubber layer uniformity ≥98%) ensure consistent product performance. For example, the printing resistance of printing blankets increases from 300,000 sheets to over 500,000 sheets, and the service life of water-stop belts is extended to more than 30 years.
   
   
3. Cost Optimization: The material utilization rate is increased from 60%-70% in traditional processes to over 90%, reducing rubber material waste; integrated production reduces intermediate links (such as secondary bonding and trimming), lowering labor costs by 40%.
