1 ) INTRODUCTION OF PLASTICS IN AUTOMOBILE

Although the rate of usage of plastic materials in engine cars and commercial cars is elevating year by simply year, the actual percentage of plastics found in an average car is among 15-20%. However it is noticed by the two automobile plus the plastic market that this is just the beginning plus the amount of plastics used in vehicles is going to treble within the next five years, at the price of metallic and its metals.

In essence the reason for the amazing growth is based on the discussion of 3 elements:

• A growing understanding of you will & capacities of plastics materials.

• An improving capability of plastics due to the overall look of new supplies, improved attributes with existing types & better finalizing equipment.

• A steady reduction in the cost of fundamental plastics recycleables relative to the cost of such traditional materials because metals, ceramics, leather & paper.

Plastic materials are now generally recognised by simply automobile producers not only like a key to attaining an improved fuel/performance ratio by simply replacing metal for home body elements but likewise as a way to many of their very own manufacturing, design and style, styling, and cost challenges. The diversity of houses offered by plastics materials on the whole &, especially, by the recently developed ceramic material makes them even more useful & attractive to engineers.

Also we can see the growth of plastic parts in Automobile in recent years by following graph.

In season 2000 in Europe more than 1 . eight million a lot of plastics were used in the Automotives in about one thousand various parts. The following piagraph shows the end result.

1 . 1 Upgrading Metal with Plastics: There are several reasons why upgrading metal parts with plastic-type material makes sense. Here is why plastic-type may be the most suitable choice for your parts. a) DECREASE PIECE COMPONENT PRICES

A penny saved is actually a penny gained. After primary tooling costs are paid out, the part part costs is usually a smaller amount than the same part produced in metal, whether it is a stamping, casting, or possibly a die cast portion This cost savings is realized because the treatment molding method has faster cycle occasions (more parts made per machine hour) and these kinds of parts happen to be identical from to the other which removes secondary machining.

b) ELIMINATE TIME CONSUMING AND COSTLY SUPPLEMENTARY OPERATIONS

Eliminating secondary procedures further minimizes costs. Plastic material can be colored with color concentrates prior to molding - eliminating secondary painting procedures. Injection molds can be uneven or presented various numbers of polished floors before molding. The high priced assembly of several steel 2

stampings or castings fastened collectively can often be replaced by a single injection cast part adding the features with the total assemblage. If multiple assemblies are required, the plastic-type material parts may have snap-together features to get rid of any nails. Eliminating sub-assembly tooling or perhaps fixtures through the use of injection-molded parts can accelerate delivery in new product creation programs.

c) REDUCE MERCHANDISE WEIGHT AND IMPROVE CONSUMER EASE

A single primary advantage of using plastics instead of metals is fat loss Reducing product weight with plastics will give you more parts per pound of material, substantially reduces delivery costs and improves the end-user' physical ease in utilizing the merchandise A comparison in the specific the law of gravity values of metals to plastics can be shown in the following desk: 1 . 1 TABLE: -1. 1 A comparison of Sp. gravity values

Choosing plastic-type over material gives you products that are light, easier to use and yet possess elevated structural strength. Plastic parts can be better than material...
