What is the exact area of materials processed per hour by non-plastic coating machines?

In numerous industrial production fields, non-plastic coating machines play an extremely important role. The area of materials that can be processed per hour by these machines not only directly relates to production efficiency but also has a profound impact on an enterprise's production capacity planning, cost control, and market competitiveness. Understanding this key indicator helps enterprises make more scientific and reasonable decisions in aspects such as equipment selection, production arrangement, and resource allocation.

I. Overview of Non-plastic Coating Machines
(I) Working Principle
Non-plastic coating machines mainly apply coatings evenly onto the surfaces of non-plastic materials through specific coating devices. Common coating methods include roller coating, spray coating, and brush coating. For example, roller coating involves the contact and rolling of the coating roller with the material surface to make the coating adhere to the material; spray coating uses high pressure to atomize the coating and then sprays it onto the material surface. Different coating methods have their own advantages and disadvantages and are suitable for different materials and coating requirements.
(II) Main Components
Its main components include the coating material supply system, coating device, drying system, and transmission system. The coating material supply system is responsible for accurately providing an appropriate amount of coating material; the coating device, such as the coating roller or spray gun, directly acts on the material for the coating operation; the drying system is used to quickly dry the coating so that the coating solidifies on the material surface; the transmission system ensures that the material is stably and uniformly transferred between various processes, guaranteeing the continuity of the coating process.

II. Factors Affecting the Area of Materials Processed per Hour
(I) Equipment Design and Specifications
Coating Width
The coating width of the equipment is a key parameter. A wider coating width means that a larger area of the material can be covered in a single coating process. For example, a non-plastic coating machine with a coating width of 1 meter can theoretically double the area of materials processed in the same time compared to a machine with a coating width of 0.5 meters, assuming other conditions are the same.
Transmission Speed
The speed of the transmission system directly determines the length of the material passing through the coating machine per unit time. High transmission speed can significantly increase the area of materials processed per hour. However, the transmission speed cannot be increased indefinitely as it needs to be balanced with the coating quality, because excessive speed may lead to uneven coating and sagging problems.
(II) Coating Process Requirements
Coating Thickness
A thicker coating requires more coating time and drying time. If a higher coating thickness is required, the area of materials processed per hour will inevitably decrease. For example, in the processing of metal coatings with high requirements for protective coating thickness, compared to the coating processing of paper with a thin coating, the production efficiency will be significantly reduced.
Coating Uniformity Requirements
To achieve extremely high coating uniformity, the equipment may need to perform multiple coatings or adopt more refined coating control techniques, which will increase the processing time for a single piece of material and thus affect the area processed per hour. For example, in the coating treatment of high-end electronic product casings, where the requirement for coating uniformity is very strict, the processing speed is much slower compared to that of ordinary industrial product coatings.
(III) Material Characteristics
Surface Flatness of Materials
Materials with a flat surface are easier for the coating to adhere to evenly and can be coated at a faster speed. Materials with a rough and uneven surface may require pretreatment or a reduction in speed during the coating process to ensure coating quality, which will reduce the area processed per hour. For example, smooth metal sheets may have higher coating efficiency than textured wood.
Water Absorption and Oil Absorption of Materials
For materials with strong water absorption or oil absorption, the coating may be absorbed more quickly, which may require adjusting the coating formula or increasing the number of coating passes, thereby affecting the processing efficiency. For example, paper has stronger water absorption than ceramic, and the coating process for paper may require more complex process control and is relatively slower.

III. Comparison of the Processing Areas of Different Types of Non-plastic Coating Machines
(I) Roller Coating Non-plastic Coating Machines
Characteristics
Roller coating non-plastic coating machines are known for their good coating uniformity and high coating material utilization rate. They apply the coating evenly onto the material surface through the rotation of the coating roller.
Processing Area Range
Generally speaking, the area of materials processed per hour by small roller coating non-plastic coating machines is approximately between 50 and 200 square meters. Such machines are usually suitable for small enterprises or scenarios with low processing volume requirements, such as the coating processing of small handicrafts. Medium-sized roller coating machines can process an area of 200 to 500 square meters per hour and can meet the production needs of medium-sized enterprises, such as the coating treatment of wood in some furniture manufacturing enterprises. Large roller coating non-plastic coating machines can process an area exceeding 500 square meters per hour and are often used in large-scale industrial production, such as the surface coating treatment of building materials.
(II) Spray Coating Non-plastic Coating Machines
Characteristics
Spray coating non-plastic coating machines can apply coatings to materials with complex shapes, and the coating thickness is relatively easy to control. They atomize the coating by high pressure and spray it onto the material surface.
Processing Area Range
The area of materials processed per hour by small spray coating non-plastic coating machines is approximately between 30 and 150 square meters. Due to their high flexibility, they are often used in personalized customized product production or small-batch and multi-variety production scenarios, such as the coating in artistic creation. Medium-sized spray coating machines can process an area of 150 to 400 square meters per hour and are suitable for production with a certain scale and diverse product shapes, such as the coating processing of automobile parts. Large spray coating non-plastic coating machines can process an area of more than 400 square meters per hour and play an important role in the surface coating treatment of large mechanical equipment.
(III) Brush Coating Non-plastic Coating Machines
Characteristics
Brush coating non-plastic coating machines have a relatively simple equipment structure and are more flexible in operation. They can apply fine coatings on materials with special shapes or small areas.
Processing Area Range
The processing area of brush coating non-plastic coating machines is relatively small. Small ones usually process an area of between 20 and 100 square meters per hour. They are mainly applied in occasions with extremely high requirements for precision but a small processing volume, such as the coating of high-end watch dials or small precision instrument parts.

IV. Methods to Increase the Area of Materials Processed per Hour by Non-plastic Coating Machines
(I) Optimizing Equipment Parameter Settings
Reasonably Adjusting Coating Speed and Pressure
According to the characteristics of materials and coating requirements, precisely adjust the coating speed and pressure. Under the premise of ensuring coating quality, appropriately increasing the coating speed and pressure can increase the area of materials processed per hour. For example, for materials with a smooth surface and low requirements for coating thickness, the pressure of the coating roller and the transmission speed can be appropriately increased.
Optimizing the Coating Material Supply System
Ensure that the coating material supply system can stably and efficiently provide coating materials. Adopt advanced flow control technology to make the flow rate of the coating material perfectly match the coating speed and avoid affecting the processing efficiency due to insufficient or excessive supply of coating materials.
(II) Improving the Coating Process
Adopting the Technology of Simultaneous Multi-layer Coating
For some permitted coating processes, try to adopt the method of simultaneous multi-layer coating. For example, in some coatings with composite requirements for color or function, by using special coating devices to apply multiple layers of coatings simultaneously, the number of coating passes can be reduced, thereby increasing the area processed per hour.
Optimizing the Pre-drying and Post-drying Processes
Reasonably arrange the time and temperature of pre-drying and post-drying. For some coatings with fast drying speed, the drying time can be shortened, or more efficient drying methods, such as infrared drying or microwave drying, can be adopted to accelerate the circulation speed of materials in the coating machine.
(III) Material Pretreatment
Surface Planarization Treatment
For materials with uneven surfaces, perform planarization treatment, such as grinding and polishing, before coating to make the material surface more suitable for rapid coating and improve processing efficiency.
Pretreatment to Improve the Affinity between Materials and Coatings
Through some chemical or physical methods, such as surface activation treatment, improve the affinity of materials for coatings, reduce the adhesion time of coatings on the material surface, and thus increase the area processed per hour.

V. Application Cases and Analysis in Actual Production
(I) Furniture Manufacturing Industry
In furniture manufacturing, wood is the main object processed by non-plastic coating machines. A medium-sized furniture manufacturing enterprise adopted a roller coating non-plastic coating machine. By optimizing the coating speed and pressure and performing surface planarization pretreatment on the wood, the area of wood processed per hour was increased from the original 250 square meters to 320 square meters. Meanwhile, due to the improvement in coating quality, the product qualification rate was also increased from 85% to 92%, greatly improving the enterprise's production efficiency and market competitiveness.
(II) Metal Processing Industry
A metal processing enterprise was applying protective coatings to metal sheets. When using a large spray coating non-plastic coating machine, by adopting the technology of simultaneous multi-layer coating and optimizing the drying process, the area of metal sheets processed per hour was increased from 450 square meters to 550 square meters, and the protective performance of the coatings was also enhanced. This enabled the enterprise to meet order requirements while reducing production costs and winning more trust from customers.
(III) Artistic Creation and Handicraft Industry
In the fields of artistic creation and handicraft production, due to the personalized and diversified requirements of products, small brush coating or spray coating non-plastic coating machines are widely used. For example, a handicraft studio used a small spray coating non-plastic coating machine to apply coatings to ceramic handicrafts. By precisely adjusting the spraying parameters and performing special pretreatment on the ceramic surface, while ensuring a beautiful coating effect, the number of ceramic handicrafts processed per hour was increased from 10 to 15, meeting the growing market demand for its products and improving the economic benefits of the studio.

In conclusion, the area of materials processed per hour by non-plastic coating machines is affected by multiple factors. In actual production, enterprises need to deeply understand these factors, and according to their own production needs, material characteristics, and coating requirements, reasonably choose equipment types, optimize equipment parameters and coating processes to increase the area of materials processed per hour and achieve efficient and high-quality production.
