What types of materials are commonly used in injection molding for air purifiers?

Injection molding is a popular manufacturing process used to produce various components of air purifiers. The choice of materials for injection molding in air purifier manufacturing depends on the specific requirements of the part, including factors such as strength, durability, chemical resistance, and cost. Common materials used in injection molding for air purifiers include:
ABS (Acrylonitrile Butadiene Styrene): ABS is a widely used thermoplastic known for its excellent impact resistance, toughness, and ease of processing. It is often used for housing and structural components in air purifiers due to its durability and ability to withstand mechanical stress.
Polycarbonate (PC): Polycarbonate is a transparent thermoplastic known for its high impact resistance, optical clarity, and excellent dimensional stability. It is used in air purifier components that require transparency or resistance to UV radiation.
Polypropylene (PP): PP is a versatile thermoplastic known for its chemical resistance and low density. It is often used for components like filter housings and air ducts in air purifiers due to its resistance to moisture and chemicals.
Polyethylene (PE): Polyethylene is a lightweight thermoplastic with good chemical resistance. It is used for components that require flexibility and resistance to chemicals, such as seals and gaskets in air purifiers.
Polyurethane (PU): Polyurethane is a flexible and durable thermoplastic elastomer used for molding seals, gaskets, and vibration-damping components in air purifiers. It offers excellent abrasion resistance and flexibility.
Polyethylene Terephthalate (PET): PET is a clear and strong thermoplastic often used for injection-molded parts that require transparency and dimensional stability, such as windows or display panels on air purifiers.
Nylon (Polyamide): Nylon is a tough and durable thermoplastic known for its high tensile strength and resistance to impact. It is used in air purifier components that require these properties, such as fan blades and impellers.
PVC (Polyvinyl Chloride): PVC is known for its chemical resistance and flame-retardant properties. It is used in certain air purifier components, especially those requiring fire resistance.
TPE (Thermoplastic Elastomers): TPEs are a family of flexible and rubber-like materials with good elasticity and impact resistance. They are used for soft-touch grips, seals, and gaskets in air purifiers.
Glass-Filled Plastics: Some air purifier components may be made from glass-filled plastics, such as glass-filled nylon or glass-filled PBT, to enhance their stiffness and mechanical properties.
The choice of material depends on the specific requirements of each air purifier component, such as its intended function, exposure to environmental factors, and the desired aesthetic properties. Manufacturers select materials that offer the best combination of performance, cost-effectiveness, and manufacturability for their particular air purifier design.
