Structural web is one of the methods that are used to create plastics. It is also called gas assist. This is because it is done under very low pressure. It is the method that is mostly used to produce components with consistent surfaces that are smooth. Moreover, it could be used to manufacture thick cross sections that are hollow thus used for many different purposes.
The process begins with a mold cavity into which plastic resin is injected. The next thing that must be introduced into the cavity is nitrogen gas. It is important that this is done in low pressure as this reduces the amount of energy that is used in the process. Also, this pressure helps the gas to push the molten plastic out into the cavity walls, by acting on the less resistant parts. This ends up creating hollow products.
This process is highly contrasted to the structural foam method which makes use of a chemical drying agent. This agent is mixed together with the polymer that has previously been melted. They have to be mixed in low volumes and pressure so that expansion can occur efficiently. After all this has occurred, you will end up with a component that is very strong, and whose surface does not have any sink marks.
One of the many advantages of using the structural web method is the quality of all the surfaces of the components that are produced. They usually have a glossy appearance thus are mostly used by clients who value the overall outlook of the product. Also, the procedure leaves no marks on the surface thus bring out a smooth texture. It can also be designed to your specifications in terms of colour and texture, thus is great for customizing.
The material costs that are required for this method are not as much, as the amount of material that is needed is also less. This is why the resultant weight of all the products is less than that of the alternatives. This does not, however, reduce the strength of the product, as it can very well perform many functions.
This method also produces parts from many different kinds of resins. It may not be confined to a specific type as it is flexible enough to accommodate all kinds of plastics, from the normal and common ones like polyethylene, to those that are engineered. This makes the process have an edge over the normal injection molding, as it cannot handle some of the resins or additives.
At the moment, this is probably the newest method of manufacturing plastic. It requires special equipment to execute it efficiently, thus may prove quite expensive at the beginning. However, later in the process, a lot more can be saved in terms of raw materials used and the amount of money input. It also has faster cycle times thus is quite time consuming.
Before resorting to the structural web, it is important to make sure that you critically look at all the pros and cons. The determining factor should be the end product and also the cost and time constraints. However, at the end of the day, what the client wants is what matters.
