What is a PP punched plate ?
PP punched plate, also known as polypropylene punched plate, is a type of sheet made mainly from polypropylene (PP) through punching processing technology.
Advantages of PP punched plate
High strength. Although PP has a low density, by adding reinforcing agents and optimizing processing techniques, PP punched plates can have high strength and rigidity, withstand certain external impacts and loads, and meet various mechanical performance requirements in practical applications.
Good insulation performance. PP material itself has good electrical insulation properties, which makes PP punched plates widely used in electrical, electronic and other fields that require insulation performance, such as insulation partitions for electrical equipment and casings for electronic instruments.
Limitations of the PP punched plate
Poor wear resistance. Due to insufficient surface hardness, the wear resistance of PP punched plates is also poor. In environments with frequent friction or contact wear, the surface is prone to wear, resulting in problems such as reduced thickness and increased aperture of punched plates, which in turn affect their performance and service life.
Easy to scratch. The surface hardness of PP punched plates is relatively low, and they are prone to scratches when in contact or friction with other objects, affecting their aesthetics and surface quality.
The main function of PP punched plate
PP punched board has the main functions of ventilation, air permeability, filtering and screening, protective isolation, decorative aesthetics, and sound absorption and noise reduction. It can promote air circulation and heat dissipation, filter and intercept particulate impurities, serve as a safety barrier and area partition, add beauty to buildings and interiors with its unique appearance, and absorb sound waves to reduce noise.
The working principle of PP punched plate
The working principle of PP punching board is mainly to use its punching structure to achieve functions such as ventilation, filtration, screening, sound absorption and noise reduction. At the same time, with the characteristics of corrosion resistance, insulation, lightweight and high strength of PP material, it plays an important role in multiple fields.
There are various types of PP punched plate , how to choose the one that suits you
一、Size and specifications
1.Dimensional accuracy. If high installation accuracy is required, such as for use in some precision equipment components, it is necessary to choose PP punching plates with high dimensional accuracy to ensure accurate fit with other components. Generally, punched plates produced by regular manufacturers will indicate the size tolerance range in the product description, which can be used for selection.
2.Customization requirement. When standard sized punched plates cannot meet the usage requirements, customization needs to be considered. Some manufacturers can customize production according to customers’ specific size, hole type, aperture and other requirements, but the price of customized products is relatively high and the production cycle may be long, so the pros and cons need to be weighed according to the actual situation.
二、Color and appearance
1.Color selection. PP punched board has multiple colors to choose from, and the selection should be based on the usage scenario and aesthetic requirements. When used for exterior decoration of buildings, punched plates that match the color of the main building can be selected; When used for commercial display, bright and eye-catching colors can be chosen to attract attention.
2.Appearance quality. Pay attention to whether the surface of the punched plate is smooth and flat, and whether there are defects such as burrs, cracks, and missing materials. Punching plates with good surface quality are not only aesthetically pleasing, but also less likely to scratch personnel and other objects during use, while ensuring stable performance.
三、Cost factors
1.Product price. There are significant differences in the prices of PP punched plates from different manufacturers, specifications, and performance. On the premise of meeting usage requirements, it is possible to compare prices from multiple suppliers and choose products with high cost-effectiveness. But don’t just rely on price as the only selection criterion, you also need to consider factors such as product quality, performance, and after-sales service comprehensively.
2.Service life and maintenance cost. PP punched plates with good quality and excellent performance have a long service life and low maintenance costs. Although its purchase price may be relatively high, in the long run, it can reduce overall costs. Therefore, when choosing, it is necessary to comprehensively consider the product’s service life and maintenance costs, and choose an economical product.
四、Punching characteristics
1.Hole pattern. Common hole patterns include circular, square, rectangular, elliptical, etc. The perforated plate with circular holes has good ventilation performance and uniform stress distribution, which is suitable for most ventilation, filtration and other applications; Square holes and rectangular holes are more common in situations that require fixation, protection, or decorative effects, such as as as protective fences, decorative screens, etc; Elliptical holes have some advantages of both circular and rectangular holes, and can be selected according to specific needs.
2.Aperture and spacing between holes. The size of the aperture directly affects the ventilation rate, filtration accuracy, and other performance of the punched plate. The larger the aperture, the greater the ventilation volume, but the lower the filtration accuracy; On the contrary, the smaller the aperture, the smaller the ventilation volume, and the higher the filtration accuracy. The spacing between holes will affect the strength and appearance of the punched plate. Generally speaking, the smaller the spacing between holes, the higher the strength of the punched plate, but the ventilation volume will correspondingly decrease. The aperture and spacing of holes need to be determined comprehensively based on the requirements of ventilation, filtration, protection, etc. in practical applications.
