The production process of ceramic tableware is a complicated and careful one with many links, that is, molding, drying, firing, glazing treatment, etc. All the links will bring troubles that affect the quality of the final product. As a professional manufacturer of ceramic tableware machinery, Yutai knows such usual troubles and provides some solutions to further enhance production efficiency and quality of products. Moreover, the Chaozhou Ceramic Manufacturers Association has also assisted ceramic companies in the promotion of industry standards, technology sharing, and resource sharing by facilitating manufacturers to streamline and make their production more efficient.
Product Crack Problem
Cracks are one of the most common flaws in ceramic tableware production. Cracks may be formed in the molding, drying, or firing process. Especially in firing, due to inadequate temperature control, ceramics may expand or shrink and form cracks.
Solution:
Control Pressure Molding: Use ceramic forming machines to create precise pressure controls so that the ceramics are not pressed too strongly in molding and to reduce the chances of cracking.
Optimize the Drying: The drying must be carried out step by step to avoid unbalanced stress by rapid drying. Even drying can be achieved through improving drying equipment (e.g., constant temperature drying kiln).
Monitoring of Firing Temperature: Use advanced temperature control equipment in an effort to track the firing temperature in real-time to avoid temperature cracks.
If you are facing the same problem, we can help you out. Our machines are equipped and reliable, and our kilns are diversified in looks and advanced in terms of functioning, providing you with customized product shape solutions.
Uneven Glaze
Asymmetrical glaze is one of the common quality faults of ceramic tableware, and it can be described as too thick or too thin in one area, or bubbles and spots. Asymmetrical glaze not only affects the appearance but can reduce the durability of the product.
Solution:
Glaze Mixing Precision: Have the glaze recipe precise to avoid glaze issues caused by uneven ingredients.
Even Glaze Spraying: Use computerized glaze spraying equipment to spray the glaze evenly onto the ceramic surface. Control the nozzle, air pressure, and spraying speed of the spray machine to provide an even layer of the glaze.
Regulate the Atmosphere at Firing: While firing, make sure the kiln’s atmosphere and temperature are steady in order to guarantee even glaze.
Our machines also have a solution to this problem. The most outstanding advantage of our automatic glazing machines is that they can achieve perfect results for each product, meeting the needs from spraying to dipping glaze, from automatic glazing lines to manual internal glazing, etc.
Inconsistent Size
When producing ceramic tableware, dimensional differences between different batches may cause the product to not meet the specification requirements. Inconsistent size will affect the appearance and user experience of the product, especially in large-scale production.
Solution:
Improved Molding Accuracy: Use high-tech molding machines, i.e., CNC presses or auto mold systems, to ensure the accuracy of the molding size of each product.
Regularly Check and Calibrate Equipment: Maintain equipment accuracy, calibrate the equipment regularly, and make sure the equipment accuracy will not be altered during production.
Streamline the Production Process: Sensibly schedule the order of the production process, eliminate excessive human intervention, and maintain stability of the production process.
Please don’t worry if you meet problems, our automated ceramic tableware production line has advanced fully automated ceramic production technology and one-stop ceramics machine solutions to help you simplify the production process and improve production stability and consistency.
Color Difference Problem
Color difference problems are more common in the production of ceramic tableware, especially for colored glaze ceramics. Color differences may occur between different production batches, resulting in inconsistent product appearance and affecting the overall quality.
Solution:
Harmonize Raw Material Lots: Ensure the raw material used for every production comes from the same batch in order to avoid color variation problems as a result of difference in raw material color.
Strictly Regulate Glaze Formula: Use standard glaze formulas and strictly regulate the proportion so that the color of glazes is not altered between lots.
Temperature Variations Control: At the firing process, control temperature and kiln atmosphere consistently so that irregular color is avoided due to temperature variation or kiln atmosphere variation.
In order to solve color difference problems, we also have corresponding solutions. Our ceramic kilns provide precise temperature control and uniform firing for your ceramic products, and ceramic printing machines provide high-resolution printing and excellent color accuracy.
The ceramic tableware manufacturing process is complex and demanding, and thus some problems are difficult to avoid. However, with the continuous innovation of technology and the entry of mechanized equipment, many problems can be well resolved by streamlining processes and equipment.
As a high-quality ceramic machinery manufacturer, we are always dedicated to providing more precise and efficient production equipment to help customers improve product quality, reduce production costs, and improve overall production efficiency.
The Role of the Chaozhou Ceramic Manufacturers Association
The Chaozhou Ceramic Manufacturers Association plays the role of bridge among manufacturers, offering technical support, industry information, and resource integration. Through the platforms of the association, manufacturers can have access to high-end equipment, innovative production technology, and cooperative resources to enhance efficiency and competitiveness in the international market. Through the assistance of the association, manufacturers can raise their quality standards, streamline production lines, and enhance their industry influence.
