Polyurethane injection molding has the characteristics of high quality and high precision, and can accurately manufacture customized injection molded products of various shapes and sizes. The process of custom injection molding of polyurethane involves several steps, including raw material preparation, mold design, injection molding, and demolding.
Polyurethane injection molding is widely used in various fields such as automobiles, daily necessities, ships, electronic appliances, medical, and construction due to its excellent physical and chemical properties.
Application of Polyurethane Injection Molding in the Automotive Industry
One huge advantage that polyurethane provides in automotive injection molding manufacturing is that it can reduce weight and significantly improve the “mileage” or fuel economy of the car, enhance comfort, provide insulation and corrosion resistance, and also effectively isolate external noise. Polyurethane injection molding is widely used in the manufacturing of automobile parts, such as foam in automobile ceilings, bumpers, comfortable car seats, bodies, windows, doors, and spoilers.
Daily Use of Polyurethane Injection Molding
In daily life, the application of polyurethane injection molding materials is also very common, penetrating various aspects of daily life, including but not limited to:
- Packaging
The main function of polyurethane packaging foam is to fix and protect the goods that need to be kept in place during the whole transportation period, which can play a good buffer role. It is mainly used for the safe transportation of fragile items, such as medical equipment, electronic products, industrial parts, glassware, and any other items that may be damaged during transportation, and can provide good protection and cushioning.
- Clothing
Polyurethane wire can be mixed with nylon material to make stretchable lightweight fabrics. Manufacturers have researched and manufactured polyurethane coatings, thermoplastic elastomers, and spandex. In addition, polyurethane injection molding technology is becoming increasingly complex, and various materials made of synthetic leather and leather are widely used in the production of clothing, especially some sportswear and accessories, due to their good breathability.
- Floor
In some building materials fields, polyurethane is often mixed with the materials used to make flooring, making these building materials stronger, easier to maintain, and more aesthetically pleasing. Polyurethane injection molding is also used for coating flooring to prevent solvents and scratches, extend its service life, and make it easy to maintain and clean. Polyurethane injection molded veneers can be used to refurbish old floors or coat new cement, veneer, or wooden floors, making floor replacement easier and more convenient. In addition, manufacturers use some soft polyurethane to make cushioning carpets, which can extend the service life of carpets. This technology is widely used in commercial and residential buildings to provide comfort and extend the service life of carpets, absorb environmental sounds, and isolate certain noise.
- Furniture
Flexible polyurethane is a very popular material in the injection molding market, widely used by manufacturers for household furniture, bedding, furnishings, and carpet lining. Its excellent sound insulation effect is used as a cushion for interior decoration, as well as increasing the comfort, support, and durability of furniture.
Application of Polyurethane Injection Molding in Electronic and Electrical Appliances
The application status of polyurethane injection molding in electronic appliances is also irreplaceable, such as:
- Electronic Products
Non-foamed polyurethane components are widely used in the electronic and electrical industry. For the sealing, compression, and insulation of some fragile and pressure-sensitive small components, as well as the manufacturing of circuit boards and underwater cables, polyurethane injection molding is a good choice. This manufacturing process can meet various electrical, thermal, and physical performance requirements. They are highly suitable for protecting electronic products due to their adhesive and insulating properties, as well as excellent waterproof properties.
- Home Appliances
The polyurethane injection molding process is widely used for insulation, insulation, or coating of electrical appliances. Currently, most household appliances contain at least some polyurethane components. Rigid polyurethane foam is composed of a tight cell structure and cell gas to prevent heat transfer. In large household appliances, hard foam is used for heat insulation of refrigerators, freezers, etc. It can help home appliance manufacturers achieve energy levels.
Application of Polyurethane Injection Molding in the Field of Construction
Polyurethane injection molding is mainly used in the manufacturing of various paint coatings and composite wood in the field of construction.
- Paint
Polyurethane injection molding resin is used as a two-component and one-component coating, which can be applied to various applications of paints and coatings. Polyurethane is used to manufacture moldable thermosetting plastics. The most common applications are automotive repair primers, building and furniture coatings, product coatings, and some special-purpose coatings. This material is mainly used for various durable high gloss coatings, such as automotive, flooring, industrial applications, and wood coatings, as well as some polyurethanes for modifying alkyd resins, which are used for paints, enamels, and varnishes.
- Composite Wood
At present, manufacturers have extended the use of some polyurethane injection molding to wood. Polyurethane-based adhesives help to firmly and permanently bond natural materials with artificial materials such as straw or particleboard, laminated veneer, long strips, oriented strand board, etc., enhancing their durability. Some modern materials have become possible due to the emergence of polyurethane injection molding technology, such as composite wood used for manufacturing cabinets and other household furniture. It can be said that the emergence of polyurethane injection molding technology has brought about a new development in the building materials industry.
Polyurethane injection molding technology can adopt structural foaming technology, which has excellent physical and chemical properties and is widely used in industrial, mechanical manufacturing, automotive parts, and other fields. It can withstand various friction and stress requirements.
