Engobadeira Back Print: Efficiency, economy and quality in the application of engobe

The Ricoth Back Print Engobadeira represents a new standard of efficiency and quality in the application of engobe to the lower part of ceramic pieces.
Designed to meet the demands of modern industry, it combines technological innovation, versatility and material savings, ensuring consistent results even in challenging conditions.

What is engobe and what is its importance?

O bent over is a layer applied to the lower part of the ceramic piece before firing, with the aim of prevent the flux material from sticking to the oven's refractory rollers, which operate at temperatures above 1000°C.
This process is essential to maintain the cleaning, performance and durability of the rollers, in addition to ensuring a uniform final finish on the pieces.

Engobadeira Back Print innovation and technology

The Engobadeira Back Print was developed to solve a recurring challenge in production lines: uniform application of engobe on parts with variations in planarity.
The system is composed of a flexible roll and a controlled air chamber, which automatically adjust to the irregularities of the part, guaranteeing a homogeneous and flawless layer, even on warped parts.

Among its differences are:

• Uniform and economical application – reduces raw material waste and guarantees stable quality standards.
• Anti-traction system – provides greater durability and less need for maintenance.
• Versatility – you can receive a additional rigid roller for high definition graphic applications on the bottom of parts.
• Suitable for small and large formats, adapting to the production line configuration.

Direct impact on quality and economy

During the comparative tests, Engobadeira Back Print presented a 55% to 60% reduction in engobe consumption, without compromising the quality of the application.
This economy can represent a return on investment in up to 60 days, depending on the cost of the engobe and the daily production of the factory.

In addition to material savings, the pieces presented cleaner, scratch-free surface, even in less favorable conditions, highlighting the Precise control of the application layer.

Results obtained in industrial tests

The Engobadeira Back Print was tested in different production scenarios, proving its operational efficiency and stability:

Test 1 – Large format production line

• Equipment designed for parts up to 1200 mm, tested with format 600 mm
• Working speed: 48 m/I
• Reduction: 1/15 at 75 Hz
• Product applied: 85% magnesite (highly refractory and solid material)
• Part type: dry way, with slight warping

Even outside of ideal conditions, the application was uniform and unmarked, demonstrating excellent performance of the flexible roller system.

Test 2 – High speed line for smaller parts

• Part format: 320 x 570 mm
• Line speed: 85 m/I
• Frequency: 90 Hz
• Reduction of engobadeira: 1/10, working at 80 m/min

The engobadeira kept uniformity in coverage and stability in application, even at high speed, confirming the robustness of the project.

The test results reinforce the potential of the Engobadeira Back Print Ricoth as a complete solution for enameling lines looking for greater efficiency, economy and quality in the application of engobe.

With intelligent design and precise control technology, the equipment adapts to different formats and line speeds, maintaining a high standard of performance and low operating costs.
