In today’s booming building materials market, SPC flooring has become a favorite of consumers due to its excellent waterproof, moisture-proof, wear-resistant, environmentally friendly and other advantages, and market demand continues to rise. This trend undoubtedly brings huge opportunities to SPC flooring manufacturers, and an excellent SPC floor production line is the key weapon for companies to seize the market high ground.

Analysis of the core links of SPC Flooring Production Line

● Raw Material Processing: High-quality SPC flooring cannot be separated from precisely proportioned raw materials. At the beginning of the production line, raw materials such as polyvinyl chloride (PVC) resin powder, calcium powder, stabilizer, lubricant, etc. must be strictly screened and accurately measured. This not only ensures the stability of the physical properties of the floor, such as strength and flexibility, but also affects the color and texture of the product. The advanced production line is equipped with a high-precision loss-in-weight weighing scale, which can control the error of raw materials within a very small range, laying a solid foundation for subsequent production.

● Extrusion Molding: This is the key step in the molding of SPC flooring. The evenly mixed raw materials are melted and plasticized through a high-temperature screw extruder, and then extruded into the base layer, wear-resistant layer and decorative layer of the floor. In this process, the temperature control system of the extruder is crucial. It needs to accurately control the temperature of each area to ensure uniform plasticization of the material and avoid product defects caused by uneven temperature, such as bubbles and stratification.

● Hot Pressing: Lay the extruded multi-layer sheets together while hot, so that each layer is tightly connected to form a complete SPC floor structure. The pressure, temperature and time parameters of the hot pressing process need to be finely adjusted. Too much pressure may damage the sheet, while too little pressure may result in a loose fit. Too high a temperature may easily deform the sheet, while too low a temperature may affect the laminating effect. The hot pressing machine of Kingshine Plastic Machinery is equipped with an intelligent control system that can adjust the hot pressing parameters in real time according to the thickness and material of the sheet, ensuring that the laminating strength meets the industry’s high standards and the defective rate is 15% lower than the average level of peers.

● Cooling and Shaping: The floor just after hot pressing is in a hot and soft state, and needs to be quickly cooled and shaped to solidify the shape and performance of the floor. An efficient cooling system must ensure uniform cooling to prevent the floor from warping and deformation due to uneven shrinkage. Dixiang Plastic Machinery uses a combination of circulating water cooling and air cooling to accelerate the cooling process, so that the floor is close to normal temperature when it leaves the cooling section, and the dimensional accuracy deviation is controlled within a very small range, which facilitates subsequent precise cutting and packaging.

● Cutting and Packaging: According to market demand, the shaped floor is cut into standard sizes. High-precision cutting equipment and automated control systems can ensure that the cut surface is smooth and accurate in size, reducing waste. Subsequently, the floor is neatly packaged and labeled through an automated packaging line, making final preparations for entering the market.

Common Production Problems and Solutions

● Board Delamination Problem: It manifests as the separation of the layers of the floor during use. The main reason is poor compatibility of the raw materials or loose hot pressing. The solution is to optimize the raw material formula and add a compatibilizer to enhance the adhesion between the layers of raw materials; at the same time, finely adjust the hot pressing process parameters to ensure sufficient lamination pressure and suitable temperature and time. With its profound technical accumulation, Kingshine Plastic Machinery provides customers with customized raw material formula suggestions and hot pressing process solutions to effectively eliminate the hidden dangers of board delamination.

● Dimension Deviation Problem: The size of the finished floor does not meet the standard, affecting installation and appearance. This is usually due to the unstable process of extrusion and cooling. Start with the stability of the screw speed of the extruder, the uniformity of temperature, and the consistency of the cooling rate of the cooling system to troubleshoot the problem. Kingshine Plastic Machinery production line has built-in high-precision monitoring sensors, which provide real-time feedback of the dimensional data during the production process, and automatically adjust the process parameters with the intelligent control system to control the dimensional deviation rate at the industry-leading level.

● Surface Quality Defects: Such as pitting, scratches, and uneven color on the surface of the floor. On the one hand, the finish and precision of the mold must be ensured to prevent damage to the board surface during extrusion molding; on the other hand, the distribution of air and water flow in the cooling process must be optimized to avoid uneven surface stress caused by excessive local cooling. Kingshine Plastic Machinery uses high-quality mold steel, which is precision-processed and polished to ensure a smooth extruded surface of the board; the cooling system is specially designed to achieve uniform and gentle cooling to ensure a flawless floor surface.
