In the past several decades, use of lightweight alternatives like plastics and composites has increased because of its increased used in the industries like aerospace, automotive and consumer electronics industry. These days, cars have more than 150 kilograms of plastic on-board in the form of engine components. For example, Boeing 787 has 50% of carbon fiber reinforced plastic.

Plastics have good mechanical properties and it is far lighter than metal that making the products much more efficient and providing adequate amount of toughness so that they can withstand the test of time. But the plastic designers need to be sensitive to some mechanical and physical properties of the plastics. It is not a strong metal and has a relatively lower density than other metals. It is a poor conductor of heat and electricity.
Injection molding is one of the most widely used manufacturing processes. However, due to the complexities of the product designers are required to make appropriate considerations about designing of parts and focus on the maximizing the performance of mold and reduce the tooling costs. It is this particular area that plagues the entire injection molding industry. When mass volume production London of plastic is used injection molding is used.

Plastics have a higher rate of thermal expansion than the metals and thicker sections shrink more than the thinner section which causes sink mark or war page at the time of molding process. Stress concentration is another area which is of a particular concern at the time of manufacturing of plastic parts. These types of stresses are the result of continuous load, war page or any other similar issues related to the materials, designs, processing and the tooling factors. Apart from that there can be a number of hidden defects in the plastic parts which cannot be detected by a routine quality process.

Performance of the plastic parts and its cost can be improved by design features. With the help of simple designs and by simple design process or by following moldable guidelines for the plastic parts, design engineers can avoid the issues that occur at the time of manufacturing. These factors require the designers to introduce apt designing features. If you are looking for someone for plastic design UK, you need a professional.
