Plastic was introduced in the 1800s and has since been used to replace metal, concrete, fiberglass and wood in the manufacture of most appliances. For instance, a big number of utensils are no longer made of aluminum or iron but plastic. In other cases, the use of concrete on floors is slowly being replaced by plastic products. People are not surprised anymore to see artistically designed plastic seats in furniture stores. What many do not know is how these chairs (for example) are made. Well, a little introduction to structural foam molding can clear the air.
In brief, this is the process where inactive gas is mixed with plastic to produce foam. This is then allowed to flow throughout the mold to produce the desired product. Interestingly, the procedure does not require high pressure or force, but works in an environment with low pressure to give high-density polyethylene.
The flexibility of this method means that it can use different raw material; be that as it may, Polyvinyl Chloride (PVC), Polycarbonate and Polystyrene (PS) are used frequently. In fact, the method is mainly used in the production of Business Machine Housings and Containers Pallets. In addition, the technique produces point of sale Displays and Components.
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.
While you are supposed to look for a number of things in a company, it is easier to begin with the testimonials. You then need to verify if the manufacturer is fully registered and follows the environmental legislation in your area. Last but not least, check their rates and only buy from the most affordable firm.
