The use of polymers as plastics in automobiles’ construction has continued to grow over the last decades. Nowadays, mold parts are the second most commonly founded material in cars. The mold parts are considered the automotive precision parts. While providing you a concrete example in numbers, an average modern car weighing 1500 kg. That approximately made of about 20% of the plastic materials. Polymers have revolutionized the performance, safety, construction, and functionality of cars. So, for this, here are five reasons that molded parts are used in car manufacturing:
- Plastics reduce the weight of the cars
- Plastics and polymers contribute to the safety of cars
- Plastic helps in lowering car manufacturing costs.
- Produces Automotive Parts with High Accuracy
- The Ability to add The Numerous Detail on To Parts
Plastic Reduce the Weight of Cars:
The primary and the most important reason for the molded part car is that it makes the car lighter. Furthermore, also include cutting the fuel demand and greenhouse gas emissions. The plastic molded car parts are also decreased the car weight. That will result in efficient fuel consumption. Due to its lesser weight to move, the engine becomes more responsive. The final result is less fuel spent and lower emissions. That’s why manufacturers use plastic in the place of the heavier metals such as steel and aluminum. Also, the weight of the vehicle which carries the cargo is becoming lighter as more interior parts. The interior parts also include the engine is made from plastic molding.
Plastics and Polymers play a role in The Safety of Cars:
Polymers play an important role in car safety; for example, the bumpers are made of polycarbonate. Furthermore, polypropylene, Acrylonitrile butadiene styrene, polyurethane, and polyimide are compounded with the glass fibers. The car made of these materials usually weighs 50% less than those made of alternative materials. While also absorbing four to five more energy during the impact. Besides, durable polyester fiber seat belts, airbags made of high-strength polyamides, and plastic child restraint seats have all helped make cars safer for road users.
Now windshields are made of laminated glass shatter-resistant thanks to the thin layer of plastic sandwiched between two glass layers. That is lighter and stronger than the tempered glass. In cars, polymers have also improved the sound attenuation and filters out most infrared rays. Also, it reduces the car temperature and, consequently, the use of air conditioning.
Plastic Help to Lower Car Manufacturing Costs:
The single mold component has helped manufacturers to decrease the vehicle assembly time and quickly introduce design innovations at lower costs. Plastic fuel tanks are made of high-density polyethylene to the corrosive environments inside and outside the tank. A plastic fuel tank also has a key safety feature since it can be manufactured as a single part without soldered seams, as there is no seam to fail in a collision.
Produces Automotive Parts with High Accuracy:
Errors in the design of the car parts result in future car problems. For example, the parts’ angles must be precise, failure of which can lead to leakages and fuel loss. Plastic injection molding involves low errors and high tolerance by enabling fool-proof parts that are effective and long-lasting.
The Ability to add The Numerous Detail on to Parts:
Plastic injection mold passes through a very high temperature, which causes the plastic to press harder against the mold, unlike other processes. This excessive pressure makes it possible to add the design into the parts. Furthermore, the high pressure allows the production of intricate and complex shapes. Coming up with accurate complex shapes require a good prior design. Some of the design elements which the manufacturers consider include the thickness of the walls, corner transition, boss design, gate placements, vents in the right places, and much more.
Part made of plastic is resistant to corrosion. That offers the flexibility and resilience for some added safety. These are most automotive precision parts. This product has very good thermal insulation, which reduces the noise and allows optimum space utilization.
