Processes Involved In Molding Foam Rubber Closures

Polyurethane and natural latex are two of the most common materials in foam rubbers. Latex rubber is commonly being used in mattresses this is because it has a great amount of endurance. Other purposes of this are cushioning furniture and seats, and also for roof, wall, and appliance insulation.

Rigid and flexible foams are the two most basic types. Rigid foam rubber closures are used mostly for insulation of refrigerators, freezers, and buildings. The rigid type has closed cell structure that would prevent gas movement. Flexible rubbers are used mostly for cushioning mattresses, pillows, and furniture. The flexible type has open cell structure that are being produced with high density and low density.

The formulation of each ingredient and chemical must be properly designed to achieve the desired final material. Each ingredient is consist of amount, molecular structure, and reaction temperature. These ingredients will determine the characteristics and purpose of the foam.

For example, during foaming, if the quantity of blowing agent is high, it will need high amount of water as well, this is to keep the size of bubbles and its rates of formation. The blowing amount determines the foam density. The hardness and stiffness characteristics of polyurethane can be changed as well.

Mixing the polyurethane formulation manually by using the hands can be done, but this would take long to mix it. There are some machines that can be used to make the mixing faster and would take just a few minutes to mix it. The formulations are processed in different ways and techniques.

There are five processes for the manufacturing of products Cobourg ON. First is material preparation. Liquid chemicals are delivered by tank trucks and are transferred to large containers. And from large containers, it will transferred again to smaller containers wherein they will be kept separated. Second is dispensing and mixing wherein distribution of low density foams will be used for the production. Each chemical has its own amount to be mixed with other components. Mixing tanks are used in mixing the chemicals and the produced ones are poured into a conveyor belt.

Third process is the slicing and curing of products. Before it is poured to a conveyor belt, it will be cut horizontally into smaller pieces and is stored 12 hours or more in a room temperature. They are not going to be stacked yet because it is not yet firm. After the curing, the products are sliced again according to its thickness.

Fourth, process of laminating. Board stocks are being formed by the rigid insulation panels. For insulation of appliances, liquids are injected in between the outer and inner walls of the appliances. Fifth, product molding. Distribution machines varies the chemicals that are poured. Distribution will allow the molded foams to be produced with hardness.

After all of the processes, outputs will be monitored, inspected, and tested for its physical and mechanical properties. Indentation is a very important property of a foam rubber because it will measure the quality of the product. Now, industries continue investigating ways on how to reduce and recycle scraps. Manufacturers are investigating for processes in producing new molded foams out of shredded materials.
