Structural foam is a term that is commonly used to refer to thermoplastic injection molding. These are components that have been made from the molding process and which tend to have core that is cellular. A cellular surface is one where the outer surface is usually denser than the accompanying inner layers.
Production will usually involve the combination of different chemicals and substances. When all these chemicals are combined, different items can be obtained as the end products. Common end products include point of sale displays and even business machine housings.
Different methods can be used to produce this type of foam. The common methods that are used in many industries will include; the low pressure process, typical moldings, conventional molding machines and a combination of different mold tools. Each of these methods is unique in each own way and also in the way that it is applied to produce the end result.
The low pressure process involves the use of dedicated injection machines. This machine will introduce a stream of gas in to the plastic that has already been melted. Once it has been injected in to the mold closed tool, it will subsequently form the material of that particular component that is being produced.
Molding machines can also be used in production of these types of plastics. When using these machines, blowing agents are going to be introduced in to all the materials that are being used in production. The heat emanating from the melted plastic makes all the agents to combine and react resulting in formation of plastic.
Another method that is often used is that of typical moldings. The typical moldings are in many cases used in producing larger components. Even though the method is effective, its main drawback is that the resulting products tend to have a surface that is rough and quite streaky.
Mold tools can be made in to lighter grade materials using low cavity pressure fill. The materials will often include items such as cast aluminum and cast steel. Due to this, the costs associated with this process are much cheaper as compared to the other methods.
Components made from this particular process can also be used as replacements for other common materials. Among the materials that can be replaced are wood, fiber glass and even metal. The replacement is often achieved at a reduced cost and at the same time tends to boost productivity.
When compared to injection molding, structural molding is much better. This is because the resulting products are not only thicker, but they also sturdier as compared to the products that are made from the other method. The items can also be recycled meaning that the environment will not be destroyed in any way.
Another advantage is seen in the type of machines that are used. The systems commonly known as front runner systems are easier to adjust allowing for different types of flows. They can also be assembled and dissembled very quickly. All this is done with the intention of meeting the different types of part requirements in place.
