Preparation of Rubber Compound: It is the first step. The raw materials are carefully measured and blended in a mixer to ensure evenness. Additives such as fillers, plasticizers, and stabilizers are incorporated to achieve the required properties. Measure components accurately. Use high-quality raw materials to avoid impurities. These impurities can affect the final product.
Feeding: The rubber compound is added to the feeding system. It distributes the material evenly into the gaps between the rolls. The compound is fed into the calendering machine through a hopper or feed rollers. Even distribution is crucial. It avoids defects in the final product. Check the feeding system often. Clean it to prevent blockages. This keeps feeding even and continuous. That makes the sheet quality consistent.
Calendering:The rubber compound is compressed, flattened, and molded to your desired thickness. The surface smoothness and texture of the final sheet are controlled by the rolls. The compound passes through a series of rolls. The rolls apply pressure and heat to form a sheet. The sheet is continuous. The gap between the rolls is adjusted to get the desired thickness. Watch the roll pressure and temperature settings closely. Also, regularly check the rolls for wear and tear. This is how to maintain product quality.
Temperature Control： Temperature control is crucial during the calendering process. The rubber compound is either cooled or heated depending on the specific requirements of the sheet. Temperature control systems ensure the compound reaches the optimal temperature for processing. Cooling is essential for some products to set the rubber, while heating is necessary for others to improve flow properties. Use precise temperature control systems and regularly calibrate temperature sensors to ensure accuracy.
Cutting and Finishing: The rubber sheet is cut for the application. It’s cut into lengths or shapes for further work. The sheets are cut using automated cutters or manual tools to the required dimensions. You can also apply additional finishing processes. These include trimming, smoothing edges, and treating surfaces. Make sure cutting tools are sharp and well-maintained. Also, do quality checks to ensure each piece meets the requirements.
Tailor-made structure for easy operation and installation: Our machines have a custom-made structure. It ensures ease of use and quick installation. This reduces downtime and boosts productivity.
Variety of speed ratios and capacities: We offer many speed ratios and capacities. They meet the diverse needs of most customers. This ensures the best performance for different production requirements.
High-quality construction: The machine is made with cold hard alloy cast iron rolls. They are mirror-polished to reach a surface hardness of 68-72HS. This polish ensures durability and great performance.
Robust base construction: Our machines have a heavy-duty universal base. It is made of channel steel and a precision-machined MS plate. They are made for stability and long use. Each machine is equipped with a gearbox and motor to enhance operational efficiency.
Manual nip adjustment: The nip is adjusted at both ends of the rolls. This is done manually with two separate screws. This provides a sturdy and reliable method for precise control.
Advanced reducer technology: Our machines use class 6 precision hardened gear reducers. They run with low noise and last a long time. This makes for a quieter and more efficient work environment.
Comprehensive control panel: The star-delta motor panel has automatic direction change, voltmeter, ammeter, overload relay, and three-phase indicator. It also has an emergency stop switch. This setup ensures safety and ease of use.
Effective sealing structure: It’s designed to stop oil leaks. Our seal design boosts the machine’s reliability and cuts maintenance needs.
The rubber calender is widely used in many industries. The machine can make various rubber products, such as:
Rubber Products Manufacturing Industry: Rubber calender machines make many rubber and plastic products. These include rubber sheets and rubber belts. For example, a rubber products company uses our three-roller calender machine. They use it to produce high-quality conveyor belts.
Chemical Industry: Rubber calender machines are used in the chemical industry. They produce rubber pipes, rubber seals, and other chemical-resistant products. A chemical processing plant might use our machines to create durable rubber seals for harsh environments.
Electronics Industry: The electronics industry uses rubber calender machines. They use them to make rubber seals, rubber gaskets, and other precision parts. Electronics manufacturers rely on our four-roller calender. It produces gaskets to insulate and protect electronic parts.
Automotive Industry: Rubber calender machines are essential in the automotive industry. They make car tires, rubber seals, and various car parts. Automotive suppliers use our two-roller calender. They use it to make high-performance rubber seals for car doors and windows.
Building Materials Industry: In the building materials industry, rubber calender machines make rubber gaskets. They also make other shrinkage-resistant materials. A building materials company uses our calender machine. It makes tough gaskets for construction.
Maintaining a rubber calender is vital to keep it running well and long. It’s especially key for product quality. The following are some maintenance recommendations for rubber calendars:
Training and record: The staff should be trained before the machine is used. This training will cover how to operate and care for the machine.
Cleaning: To prevent the buildup of dust and crumbs, which may contaminate the rubber, clean the machine’s surface, the drum, and the transmission system. Do this to keep the machine’s work area clean.
Lubrication: To keep the machine running smoothly, use the right lubricant. Use it to lubricate the rollers, bearings, and transmission parts. This will cut the wear and tear of the equipment and make it last longer.
Regular Inspection: Please often inspect the machine’s key parts. These include rollers, gears, motors, cables, wires, and switches. Check to see if they are worn or damaged. Also, make sure the equipment works normally.
Replacement of worn parts: Please replace the worn parts in time so as not to affect the performance of the machine.
A Rubber Calender Machine produces rubber sheets. It does this by calendering rubber into sheets of different thicknesses and surface types using multiple rollers.
