Since its introduction in the mid 19th century, plastic has been used as a substitute of wood, concrete, fiberglass and metals in many instances. For example, hundreds of kitchenware are made of plastic instead of the traditional metals like iron or aluminum. In fact, there are floors made of plastic as opposed to concrete. It is also not strange to see several plastic chair designs in the market today. So, the question is how do they make some of these chair designs? To answer that, you must understand structural foam molding.
In summary, this process involves the mixing of a foaming agent with molten polymer to mold various plastic materials. Once the inert gas (i. E. The foaming agent) has had its effect, the foam slowly takes the shape of the mold without the need of pressure. In other words, structural foam technique allows you to produce high-density polyethylene without using force.
It is true that the technique uses a number of raw materials; however, the Polyvinyl Chloride (PVC), Polystyrene (PS) and Polycarbonate are the most popular. From such materials, products such as Containers Pallets, Point of Sale Components and Displays can be produced. Business Machine Chassis also come from the foam method.
Now, before one looks into the pros and cons of this technique, there is need to know the other molding techniques. For example, there is the Blow (which is basically putting injection and extrusion techniques together), Gas Assist, Rotational and Injection molding techniques. Other popular processes include thermoforming and Film Insert. Well, every procedure mentioned has its highs and lows. Nonetheless, structural foam is still the popular choice especially where force is not needed to spread the molten polymer.
As expected, the technique has its highs and lows. For instance, many love it because it is cheaper to set up. The fact that you could use low-priced and light molds (e. G. Aluminum) has only served to popularize this technique. In addition, structural foam has lower inner stresses as compare to other methods like Compression. Finally yet importantly, the method can produce some of the largest plastic products.
Granted, structural foam method can be cheaper than most molding techniques. When it is compared to procedures such as Compression, it may end up more expensive to start and run. So, it would not be the top choice if you do not have enough money. The other shortcoming is in regard to speed, the process is slower compared to other injection techniques, especially those employing pressure.
Learning how to contract a plastic manufacturer is just as important as the description of structural foam technique, its uses and advantages. Now, that the plastic market is full of fake goods, knowing where to buy you products or whom to contract for the same is important. In fact, when a manufacturer decides to charge higher fees for low quality product then taking some precautions is in order.
There are several characteristics that define a credible manufacturer; however, you should need to read what other customers are saying. Also, check if they are legally operating and that they are in conformity with environmental laws in your state. They should also be affordable.
