LeadSub Sublimation Slate Manufacturing Process

Introduction: 

In the manufacturing domain, sublimation technology has emerged as a key method for creating unique and customizable products. Among these, sublimation slate stands out for its elegant appearance and versatility. However, manufacturing sublimation slate involves complex steps and techniques. In this article, we will delve into the key processes involved in sublimation slate manufacturing and explore the essential equipment utilized in the production line.

In the production process, we need to pay attention to many details, such as the quality of the sublimation coating, the uniformity of the spraying, the baking temperature, each factor will affect the use effect of the slate, so before introducing the production process, we first understand how to determine the quality of a slate.

1. Raw Material Quality:

    • High-quality sublimation slate: Made of natural stone, sturdy material, free of cracks, and not prone to breakage.
    • Low-quality sublimation slate: Porous material, with cracks, and prone to breakage.

2. Surface Smoothness:

    • High-quality sublimation slate: Smooth and even surface, without noticeable bumps or scratches.
    • Low-quality sublimation slate: Surface/back may be rough, uneven, or with visible imperfections.

3. Coating Integrity:

    • High-quality sublimation slate: Coating evenly covers the surface, without defects or spots.
    • Low-quality sublimation slate: Coating is uneven, may have missing or uneven spots.

4. Non-Adherence of Coatings:

    • High-quality slate: Easily separate from sublimation paper after printing.
    • Low-quality slate: Improper baking temperatures may result in coatings not drying thoroughly, causing sublimation paper to stick to the slate’s surface during printing, rendering the slate unusable.

5. Print Quality:

    • High-quality sublimation slate: Bright and vivid colors, clear details, no blurriness or missing prints.
    • Low-quality sublimation slate: Colors may be uneven, blurry, or lack details.

6. Durability of Finished Product:

    • High-quality sublimation slate: Wear-resistant, durable, and prints are not prone to fading.
    • Low-quality sublimation slate: Prints may fade easily, and the slate is susceptible to damage.

Here are some examples of poor quality stone, if not selected in the material selection, the finished product will have defects or cracks and other problems, affecting the printing effect: 

Workshop Conditions: Dust-free Workshop

Sublimation slate products are manufactured in specialized clean room environments equipped with state-of-the-art machinery such as grinders, edge finishers, automatic coating equipment, and baking ovens. This pristine environment ensures optimal product quality and consistency throughout the manufacturing process.

Process 1: Material Selection

Selecting high-quality slate as the base material lays the foundation for premium products. Each slate base undergoes meticulous inspection to ensure it meets our stringent quality standards.

Process 2: Surface Preparation

Before printing, the slate base undergoes a thorough cleaning and polishing process to eliminate any defects and create a smooth, even surface for printing.

Process 3: Edge Finishing

Following cleaning and polishing, the edges of the slate base are finished using an edge finishing machine to create unique edge patterns. As a result, the actual dimensions of the slate obtained will be approximately 0.7-1cm smaller than the measured dimensions. 

Process 4: Manual Priming

After edge finishing, the slate base is manually sprayed with a layer of white primer. This primer is essential for achieving perfect sublimation print results.

Process 5: Sublimation Coating

The primed slate base is then transferred to our automatic coating equipment for precise and uniform coating application. Our proprietary sublimation coating, carefully calibrated, achieves optimal thickness and coverage, resulting in stunning print effects.

Process 6: Baking

Following coating, the slate base undergoes baking in advanced ovens to cure the coating. Our precise temperature control ensures uniform curing, enhancing the lifespan of printed designs.

Process 7: Cooling and Quality Inspection

After baking, slate products undergo a cooling period followed by rigorous quality inspection. Well-trained technicians carefully inspect each product to ensure uniform coating and smooth surfaces.

Process 7: Packaging

Each sublimation slate is protected using bubble wrap and individually packaged to prevent damage during transportation. Our meticulous packaging ensures every product arrives intact.

Storage and Transportation

The finished products are then transferred to our warehouse for storage, where they await distribution to customers worldwide. With ample inventory and flexible shipping options, we can meet the diverse needs of our customers and ensure timely delivery.
