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 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.
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.
To appreciate the benefits of this technique, a mention of the other methods is in necessary. Well, there the main procedures include Injection, Compression, Blow (i. E. A combination of extrusion and injection methods), Rotational and Gas Assist molding methods. The other techniques include Film Insert and thermoforming. Now, each of the listed methods is good for the production of a particular product. However, foaming is considered the best in cases where the production requires no force to distribute the molten plastic.
Obviously, the technique has its own merits and demerits. On the brighter side, the process is cheaper to run. Many also love the method because it uses cheap and light molds (such as the ones made of aluminum). Additionally, it has very low internal stresses compared to Compression molding. Lastly, the technique allows the production of large plastic products.
It is true that the foam method is considerably cheaper to set up than most molding techniques. However, it can never beat Compression molding when it comes to the ease of setting up the process and the amount required to do so. Consequently, the former might not be the outright choice for those running on low budget. On the other hand, it is time consuming as it has slow production rate. When compared to injection techniques that employ high pressure, it turns out to be very slow.
After defining structural foam and looking at its application and benefits, the focus should be on how to contract a plastic molding firm. Examining some of the qualities of a credible company is of great benefit considering the fact that the market has counterfeit goods. In worst cases, even manufactures may turn out to be unscrupulous thus underscoring the need for caution.
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.
