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.
Typically, there are certain materials that are used. The materials will then result in the production of products such as business machine housings. Other products include container pallets and point of sale displays. Business machine chassis components are also produced using this particular type of molding.
When it comes to producing this kind of foam, different approaches can be used. Each approach will have an impact on the end product in terms of the texture that is achieved. Common methods will include typical molding processes, use of conventional molding machines, combining different molding tools and the use of low injection pressure.
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.
Typical moldings produced will make it possible for larger moldings to be produced. This is possible through the use of low pressure. Due to the nature of this process, the finished molding will usually have a surface that is rough and streaky. Filing and painting can then be done.
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.
Using this kind of foam will have its own set of benefits to the user. The major benefit is that this product can be used in place of traditional materials such as wood, metal and even fiber glass. The replacement is achieved at a very minimal cost and will also see an improvement in productivity.
Injection molding is another method used in production of plastics. If compared to structural molding, you will notice that the latter is more effective. All the products produced using these methods are of a thicker nature. They are also sturdier thereby making them more effective.
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.
