The PU foam injection machine is revolutionizing modern manufacturing by producing durable, high-quality components. Its versatility allows for rapid production and intricate designs, making it essential in industries like automotive and consumer goods, while driving advancements in efficiency and sustainability. Today, let’s take a look at this powerful equipment for spray and pour foam products.
Technical Parameters of polyurethane molding machine
Polyurethane injection molding machine is mainly used to mix two liquid components (polyol and isocyanate) and inject them into molds to produce various types of polyurethane foam. These machines can be divided into high-pressure and low-pressure types, suitable for foam products of different densities and hardnesses.
A complete polyurethane foaming machine consists of the following systems: material flow system, metering system, gas system, heating system, cleaning system, and mixing device.
Features of polyurethane foam injection machine
Polyurethane foam injection machines are usually divided into two types: high pressure and low pressure. High pressure polyurethane foam injection machine is suitable for producing higher density foams, while low pressure pu foam injection machine is suitable for the production of lightweight foams.
Fully automatic or semi-automatic PU foam injection machine have self-cleaning mixing heads to ensure uniform mixing of materials.
The working pressure is generally between 6-22MPa, which can meet the needs of different products.
The ratio of A and B components is usually between 1:1 and 1:3, depending on the characteristics and application of the required foam.
Foaming principle – How does the Polyurethane foam injection machine work?
The two components A and B are precisely proportioned and stirred at high speed. Two high-precision metering pumps deliver the two components A and B to the mixing head. After high-speed and intense stirring, the liquid is evenly sprayed out to form the desired product.
Polyurethane molding machine is used to produce all types of polyurethane products. For example: car seat cushions, furniture seat cushions, motorcycle seat cushions, bicycle seat cushions, office chairs, memory pillows, steering wheels, dashboards, bumpers, insulation materials such as refrigerators and heaters, toys, polyurethane cornices, casters, etc.
