When a process needs to be smooth, with no stops or unnecessary downtime - there is no room for manual operations. What counts is rhythm, repeatability and automation. In such cases, it becomes crucial to ensure an uninterrupted flow of workpieces through the heating zone - no stops, no manual loading, no wasted time. The solution is a conveyor belt integrated into the oven, which allows semi-automatic or fully automatic transport of workpieces through the heating chamber. In this way, the oven acts as a pass-through device - the workpiece arrives on the belt on one side, passes through the entire chamber and is picked up automatically or manually at the end. Such a system is ideal for batch and continuous production, where a fast, repeatable heat treatment process without downtime is important. In addition, the conveyor belt can be integrated into a larger production line, increasing the degree of automation and work efficiency. The main advantage of such a solution is the optimisation of time and resources: it eliminates interruptions associated with manual loading and unloading, enabling smooth and uninterrupted annealing of workpieces.
