Things to Know about Conveyor Belt Manufacturing


The production process of the conveyor belt is a delicate and complex process involving many links and steps. The precise execution of each link plays a vital role in the quality and performance of the final conveyor belt.

In order to better understand the production process of the conveyor belt, we must first understand two concepts, the first is the basic structure of the conveyor belt, and the second is that the production of the conveyor belt includes two concepts, one is the production of the conveyor belt rolls, and the other is the production of a single conveyor belt. Accordingly, this article by Bsbeltfactory will introduce in detail the various links in the production of conveyor belt rolls and single conveyor belts.

What is a conveyor belt?

Conveyor belt is a kind of belt for light and medium load applications, suitable for various industrial scenarios, such as food processing, light industrial manufacturing, packaging, logistics and other fields. Its structure is relatively simple and usually consists of the following main components:

Surface coating: The surface of light industrial conveyor belts is usually coated with wear-resistant and corrosion-resistant materials to ensure its stability and durability during use. Commonly used coating materials include synthetic materials such as PVC, and PU, and these materials can be selected in different types and specifications according to different application requirements.

Surface pattern: In order to increase the friction between the conveyor belt and the material, the surface of the light industrial conveyor belt is usually designed with a specific pattern. These patterns can help improve the traction of the conveyor belt, prevent material slipping and leakage, and ensure the stability and high efficiency of the conveying process.

Reinforcement: The reinforcement of light industrial conveyor belts usually consists of fibrous or synthetic materials such as polyester, nylon, aramid, etc. The function of the reinforcement layer is to increase the strength and stability of the conveyor belt, so that it can bear the weight and tension of the material, while reducing the elongation and deformation of the conveyor belt.

How to Manufacture Conveyor Belts

The process of  conveyor belt rolls manufacturing involves several steps, here is a brief overview:

Raw material preparation: 

The reliable performance of conveyor belts starts from a good formula, so it is initial to prepare high-quality PU or PVC raw materials and mix the raw materials according to a specific formula. 

To achieve the required performance and characteristics, different industries and application scenarios need to use different formulations of raw materials, such as anti-static, or anti-mold. 

At the same time, our color-matching work is also carried out in the mixing process. According to the needs of customers, we can realize the preparation of all different conveyor belt colors on the market.

Stirring and defoaming:

In this step, our skillful workers use mixing equipment to thoroughly mix the raw materials to ensure a uniform mix. At the same time, it is also necessary to eliminate the air bubbles in the mixed stock solution to prevent uneven structures or air bubble holes during the production process and ensure the quality and uniformity of raw materials, thereby ensuring the quality of the conveyor belt.

Checking and filtering: 

It is another important part of the production process. After defoaming, it is necessary to check the mixed stock solution to ensure that its quality meets the requirements. Then use filter equipment such as gauze bags to filter the mixed raw solution to ensure the purity of the mixed solution and avoid the existence of impurities or foreign matter, thereby ensuring the quality of the final product.

Coating stage:

Followed by, the inspected and filtered mixed stock solution is applied to the gray cloth. The gray cloth is the supporting material for the inner layer of the conveyor belt, and its quality and stability directly affect the overall performance of the conveyor belt. 

At this step, if there are belts that require specific patterns or textures, corresponding molds can be used for molding to give the conveyor belts the special appearance and texture required. 

According to the application requirements of different industries and different materials, we have designed more than 60 patterns and are equipped with corresponding molds for embossing work.


Subsequently, a post-processing step is performed. This includes trimming and trimming the edges of the belt to ensure it is the desired size and appearance. This step is critical to improving the overall appearance and quality of the belt.

Pack and Stockage:

Finally, after the production of the conveyor belt is completed, it needs to be sealed and packaged. The produced conveyor belt is covered with plastic film, bundled, and reeled for packaging and transportation. At the same time, it is also necessary to indicate the specification, model, production date, and other relevant information of the product, so that it is convenient for users to use and identify.

The above are all the links in the production of conveyor belt bales. We strictly control the quality of each link in the production of conveyor belts to ensure the purity of raw materials, the uniformity of mixing, the stability of gray cloth, and the fineness of post-processing. Through these meticulous processes and strict quality control, high-quality conveyor belts are produced to meet the needs of different industries and application scenarios. Different industries have different requirements for the performance and characteristics of conveyor belts, such as wear resistance, high-temperature resistance, oil resistance, etc. Therefore, during the production process, it is necessary to adjust raw materials and processes according to the needs of different industries to ensure that the conveyor belt can exert the best performance in various application scenarios.

How to Make a Conveyor Belt

In addition to the manufacturing of conveyor belt rolls, the process of making a conveyor belt is very important, because it directly affects the quality and use effect of the conveyor belt. These steps are detailed below:


cut the rolled conveyor belt bundle into the required length and width according to the customer’s requirements, using cutting tools. This step ensures that the size of the conveyor belt meets the customer’s needs.

Punching teeth:

Put a V-shaped tooth on the disconnected port, which is for the convenience of subsequent joints. The toothing is to increase the firmness and stability of the joint to ensure that the conveyor belt will not break or separate during operation.

Butt joint:

Use a bonding machine such as vulcanization equipment to butt the punching parts at both ends and bond them to form a stable interface. This step is the most critical step in the entire machining process, ensuring the quality and reliability of the interface.


Trim the corners of the interface to ensure the flatness of the interface. The smooth interface can ensure the smooth operation of the conveyor belt during work, and reduce material leakage and jamming.

Adding accessories:

According to the needs of customers, for conveyor belts that require skirts and baffles, add accessories in this link. Skirts and baffles prevent material from spilling and scattering, keeping the workplace tidy and safe.

Every link in the above steps is very important, especially the docking step, which is directly related to the service life and stability of the conveyor belt. For this, we have another article: Types and Tips of Conveyor Belt Splices in detail for your reference.


At every stage of conveyor belt production, it is necessary to strictly control the quality, and use high-quality equipment and raw materials to ensure that the final produced conveyor belt is of high quality, has stable performance, and meets the various needs of customers. 

Only in this way can the Bsbelt conveyor belt be guaranteed to run efficiently and safely in various industries and provide a reliable solution for production and material transportation.
