Conveyor belts are in use for many years and are at the core of material handling across various industries. For example quarries, mining, construction, and manufacturing are using hot splicing. The system of material handling plays vital function in the transport of bulk materials.

Since they are a vital component of industries that are heavy-duty conveyor belts, So, they have to function flawlessly throughout the day without fail. Minimal downtime and the highest output have become a major goal for different manufacturers. The maintenance of the individual conveyor components is crucial. 

The most crucial component for every conveyor is the splices. The reliability and performance of the conveyor belt is measured by how well its splices are made. But, all splices are prone to wear. 80 percent of conveyor belt failures are because of insufficient splicing. This is where how the importance of splicing conveyor belts comes into play. What exactly is conveyor belt splicing? How do you go about making splicing techniques for conveyor belts used today?

What is Conveyor Belt Splicing?

Splicing a conveyor belt, simple as it is. Also, it is the procedure of connecting two cut ends of the conveyor belt to improve the overall performance. We carry out when a new installation is being made or refurbishing programs.

Learn about two popular conveyor Belt Splicing Methods

Conveyor belt hot splicing is accomplishable using a variety of mechanical or chemical processes. These are two well-known conveyor belt splicing techniques used today:

Mechanical Splicing 

The mechanical splicing technique is an incredibly flexible option that utilizes the mechanical fastener system. It is due to create reliable joints. It is suitable for all kinds of belts with any length, width, thickness and speed. The mechanical splicing method is perfect for all kinds of belt. In comparison to other methods of splicing mechanical fasteners can be installed in just only a few minutes. We use the hammer or an upgraded installation tool using the use of air or electric power sources. Mechanical splicing can reduce belt’s waste and is suitable for both older and new worn belts. 

Mechanical conveyor belt splicing at any time without preparation. As it doesn’t affect the shelf’s life span, their residue or levels of moisture. If you decide to go for mechanical splicing, make sure that the work is completeable by person. This is crucial to ensure the longest splice lifespan and efficiency.


It is a very complex process that requires chemicals and/or heat. This process requires not just precise temperature, compression and dwell time. However, it also requires the right equipment, skills and a safe and controlled environment. Again, this is not the case with a mechanical splicing. 

The entire process for Vulcanizing a belt will take many hours. Also we need meticulous preparation prior to the process. The process of vulcanization is not reccomendable if the belt is worn out or has been worn unevenly. In general, it is much more robust than the mechanical splice. We perform vulcanization process by people who have extensive experience with adhesives. We also use solvents and other fill and cover materials. There are two kinds of vulcanization, as follows:

  • Hot Vulcanization 

We form hot vulcanization by using pressure and heat using heated presses. This method of splicing is highly efficient however it is time-consuming. It is suitable for all kinds of belts that have different thicknesses and widths. This method of making belts produces strong, long-lasting splices. As it is comparable to other methods that involve splicing belts.

  • Cold Vulcanization 

Cold Vulcanization is a secure joining technique that uses chemicals used to join the ends of rubber. This process requires expert hand tools, as well as top-quality bonding agents.

Final Words

The two conveyor belt splicing techniques involve a number of complex steps. Therefore we can execute these by a trained worker. The company that performs the splicing should be able to describe the advantages and disadvantages of each splicing technique. We should also be able identify the type of splicing technique suitable for the conveyor belt.
Additionally, if you’re searching for new conveyor belts you must make sure that the splicing equipment is in good working order. To ensure that you’re on the safe side, purchase a used or used conveyor belt from a reputable hot splicing supplier, who offers the highest quality conveyor belts that are used to handle materials.
