Oven with bottom carriage for serial heat treatment

A manufacturer of medium-sized workpieces implemented a oven with a bottom carriage system, which allowed it to speed up the painting cycle, reduce loading times and maintain the cleanliness of the chamber - without the need to expand the infrastructure or use overhead systems.

Oven with bottom carriage for serial heat treatment

Assumptions:

Processing of workpieces of medium size and weight that can be moved on the shop floor.
Need to ensure fast and repeatable loading without interrupting the heating cycle.
Lack of space for automatic transport systems and full integration into the line.

Estimated effectiveness:

Reducing loading and unloading times:
-40% against manual methods without trolley

Keeping the chamber clean:
>80% less contamination from the floor compared to manual workpiece insertion

Extension of the oven continuous operation:
+30% thanks to the possibility of preparing the next batch of parts while the previous one is curing

Proposed solution:

Even before the project started, the client carefully checked the logistics of the hall - in particular the realistic dimension of the available entrance, just in case. Despite earlier concerns, it turned out that a classic fully assembled oven would fit in without any building work or changes to the infrastructure. This made it possible to dispense with a modular solution, i.e. a kiln assembled from prefabricated segments that are transported separately and only assembled on site.

This made it possible to use a larger model to suit growing production - without compromising on size or performance, and without having to break down walls or reinforce the floor.

The final implementation was a paint oven with a bottom carriage system - in the classic configuration of two carriages (inner and outer). As a result, the workpieces are prepared outside the heating zone and then safely inserted into the chamber without the need for lifts or cranes. This form of loading not only reduces operational time, but also reduces contamination from the hall by isolating the transport process from the oven environment.

The internal trolley provides a stable base for the workpieces and can be freely adjusted, allowing a wide range of components to be handled with a single, repeatable procedure. The entire process remains manual, but ergonomic and error-proof.
