This video (made in Yixing MCD Oven Co., Ltd https://www.mcdoven.com) is about the simplified kamado grill production process! Here's a breakdown with some additional details:
1. Raw Material Preparation:
Stirring the mud: This initial step likely involves mixing a specific clay recipe with water and possibly other ingredients to create a thick, uniform slurry. The exact composition of this mixture might be a closely guarded secret for some manufacturers.
2. Molding:
Two main methods are used for shaping the kamado's ceramic parts:
Slip casting: The slurry is poured into pre-made plaster molds that absorb excess water, allowing the clay to take the shape of the mold.
Press molding: The slurry is pressed into molds under high pressure to create denser, more consistent shapes.
3. Clay embryo:
Once the mold is removed, you're left with a shaped piece of clay, often called a "green" or "clay embryo." This needs to dry completely before firing.
4. Drying:
This stage is crucial to prevent cracks during firing. The drying process is slow and controlled to allow any remaining moisture to escape evenly.
5. Bisque firing:
The first firing, at a lower temperature (around 900°C), hardens the clay structure but doesn't reach the high temperatures needed for vitrification (glass formation). This bisque firing also removes any remaining organic materials.
6. Glazing:
A liquid glass coating (glaze) is applied to the bisque-fired ceramic parts. This glaze gives the kamado its finished look, protects the ceramic from the elements, and aids in cleaning.
7. Glaze firing:
The final firing takes place at a much higher temperature (around 1300°C). This intense heat fuses the glaze to the ceramic body, creating a strong, durable, and weather-resistant finish.
8. Metal Parts Making:
While the ceramic parts go through the firing process, other factory sections might be working on the metal components like the lid hinge, cart, firebox grate, and heat controls. These parts are likely made from stainless steel or other high-quality, heat-resistant metals.
9. Assembly:
Once all the parts are complete, the ceramic body, metal components, gaskets, and any other hardware are assembled into the finished kamado grill. Strict quality checks likely happen during this stage.
This is a simplified overview, and there might be additional variations or steps depending on the specific manufacturer. You can find more detailed videos of the process in our youtube channel.
