Structural Web Method Of Manufacturing Plastics

By Marissa Velazquez


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 first step is to ensure that you have mold cavity in which all the plastic will be worked on. Plastic resin is put into the cavity by injecting it, followed by nitrogen gas under low pressure conditions. This gas forces the plastic to be pushed onto the cavity walls, especially the less resistant parts. The result of this is a hollow cross section that is important to clients in many different ways.

The difference between this and the structural foam method is that this method does not use a chemical blowing agent. In the structural foam, the agent is put into the polymer melt and mixed together for expansion to occur. It is important that a low volume of the raw materials are used so that expansion can occur properly. The result is a strong and rigid product.

The structural web method has many advantages. It ensures that the surface of each product that is produced is of very high quality in the aesthetic eye. This means that it is attractive and appealing as it is smooth and consistent all through. It also provides the client with an option of coloring it or texturing it to their own specifications and satisfaction.

Also, these products weigh less than the other products from the other procedures. This is not to mean that they are not as strong, as they are equally as rigid and can support a lot of weight. This also translates in less cost of the material used as the amount of weight needed is far less. This enables the manufacturer to be able to transfer the saved costs to other processes.

You can use many different kinds of resins and additives in this product without any restrictions. The equipment is designed to handle all types of plastic resins, from the normal ones which are commonly used, to the ones which are engineered to certain specifications. This is a convenient method as it does not limit the manufacturer to what raw material is needed, just what is available.

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.

You should ensure that you study the method and analyze it alongside all the other alternatives. If you are critical about producing cosmetic components that are very strong and appealing then the structural web is the most appropriate method. Besides, it saves a lot of time and money.
