The
outer rotor flat fan guard is an important component that protects the fan's internal rotor and external users. Therefore, many factors need to be considered when selecting manufacturing materials, including safety, durability, cost, and manufacturing processes.
metallic material:
Steel: Steel has high strength and hardness, which can effectively protect the rotor and motor inside the
fan. It also has good durability and is not susceptible to external impact or deformation. Steel is a stable material and is not easily affected by temperature changes or chemical substances. It maintains its original performance characteristics and is suitable for use under various environmental conditions. The protective cover made of steel can effectively prevent external objects from entering the inside of the fan, protecting the safety of mechanical parts and users, which is especially important in industrial environments or public places. As a metal material, steel has good processability and can be processed by stamping, welding and other processes to produce protective covers of various shapes and sizes that meet design requirements. Compared with some high-performance composite materials, the cost of steel is relatively low, which can reduce manufacturing costs while ensuring product quality. It is suitable for mass production of outer rotor flat fan protective covers.
plastic material:
Polypropylene (PP): Polypropylene has good impact resistance and chemical resistance. It is suitable for making lightweight but high-strength parts. It is often used to make protective covers for fans.
Polyethylene (PE): Polyethylene is often used to make low-cost protective covers. Although its strength is relatively low, it can still be considered for use in some light-duty applications.
Polycarbonate (PC): Polycarbonate has excellent impact resistance and transparency, and also has good heat resistance. It is suitable for protective covers that require transparent or translucent.
Polyvinyl chloride (PVC): Low-cost, but slightly less durable than other plastic materials, often used in low-cost fan guards.
glass fiber:
Glass fiber has excellent tensile strength and elastic modulus, allowing reinforced plastics to withstand larger loads in applications. Glass fiber reinforced plastic has a high surface hardness and good wear resistance, making it suitable for making wear-resistant parts. Glass fiber itself has good corrosion resistance, allowing reinforced plastics to have a longer service life in harsh environments. Compared with metal materials, glass fiber reinforced plastics have a lower density and can achieve lightweight design of products. However, fiberglass reinforced plastics also have some disadvantages. Although fiberglass reinforced plastics have high strength, they are prone to breakage when subjected to bending or impact. Compared with ordinary plastic materials, the production cost of glass fiber reinforced plastics is higher and the manufacturing process is more complicated. The surface of fiberglass reinforced plastic is not easy to repair or process, so the difficulty of surface treatment and repair needs to be considered during design.
carbon fiber:
Choosing carbon fiber as the manufacturing material for the outer rotor flat fan protective cover is a good choice because carbon fiber has many advantages, such as light weight, high strength, corrosion resistance, etc. There are different types of carbon fiber, such as pyrolytic carbon fiber, oxidized polypropylene fiber, etc. You need to choose the appropriate type of carbon fiber based on specific usage requirements. The way the carbon fibers are arranged also affects its performance. Common ones include unidirectional carbon fiber, bidirectional carbon fiber, etc. Select the appropriate fiber arrangement based on the force the protective cover needs to withstand. Carbon fibers often need to be combined with a resin matrix to form composite materials. Choosing the appropriate resin matrix can affect the properties of the composite material, such as strength, wear resistance, etc. The manufacturing process of carbon fiber composite materials is also important, such as prepreg method, manual lamination, etc. Different manufacturing processes can affect the quality and performance of the final product. Finally, you also need to consider the cost and production feasibility of carbon fiber materials to ensure that the selected material fits the budget and can be effectively used in actual production.
other materials:
Rubber: There are many types of rubber, including natural rubber, nitrile rubber, silicone rubber, and more. You need to choose the appropriate rubber type based on the usage environment and performance requirements. The rotor plate fan guard needs to have certain wear resistance and durability to protect the fan and ensure long-term use. Considering that the
fan may be used in humid or rainy environments, the material of the protective cover needs to have certain waterproof properties to ensure that the inside of the fan is not damaged.
Glass: Some fan protective covers with special requirements may use glass materials, such as tempered glass, which has high transparency and heat resistance.
