Plastic molding companies play a pivotal role in the automotive industry's supply chain, providing injection-molded parts for the automotive industry. The value of the plastic parts manufacturing industry has exceeded 28.7 billion US dollars and is expected to reach new heights in 2022. There are many reasons behind the fact that plastic parts manufacturing can greatly boost the revenue growth of the automotive industry.

Existing Problems in the Automotive Industry

Since 1908, automotive industry manufacturers have been mass-producing cars. After more than a century of development and transformation, the automotive industry has achieved numerous technological advancements. However, there are still some issues that need to be addressed to enable plastic parts manufacturing to better serve this industry.

Efficiency Issues

The production efficiency in the automotive industry varies widely, which has become a major problem affecting costs and the supply chain. Higher production efficiency means that more vehicles can roll off the assembly line, and it also enables the plastic molding companies that support it to produce parts more smoothly. The indicators for measuring the efficiency of the automotive industry are usually the number of cars produced per day and the man-hours required to complete the production of one car within a given time. Among the seven major automotive manufacturers in the United States, a Jeep assembly plant only needs 13.57 man-hours to manufacture one car, while Hyundai needs 35.1 employee man-hours. Such a huge difference in efficiency makes it difficult for plastic molding companies to provide products stably.

Quality Issues

Quality is also a major concern for many automotive manufacturers. Poor quality will directly affect car sales, which in turn will impact the plastic parts manufacturing industry and ultimately harm the entire supply chain. Although Jeep leads in production efficiency, it also has more prominent quality problems. On average, there are 167 problems for every 100 cars it produces, which is much higher than the industry average of 118.

Cost Issues

The continuous increase in car prices is partly due to production efficiency and quality factors. The longer it takes to manufacture a car, the greater the cost will increase significantly. A longer production cycle means more employee man-hours are invested, which will quickly drive up costs. In addition, quality problems will not only affect consumer confidence and brand loyalty but also have a negative impact on sales. These factors will increase the production cost of cars, which will in turn affect the plastic parts manufacturing industry.

Precision Issues

It is gratifying that the automotive industry is increasing its investment in engineering technology and production process improvement and has made certain progress in these aspects.

Advantages of Injection Molding in Plastic Parts Manufacturing

Using the injection molding process to manufacture plastic parts has many significant advantages, which can effectively solve many problems faced by the automotive industry.

Mass Production of Parts

Plastic molding companies can alleviate the efficiency concerns of the automotive industry by mass-producing injection-molded parts. Stocking these parts in advance can ensure the smooth progress of the production process and maintain high production efficiency. Of course, this requires plastic parts manufacturers to establish a close and stable cooperative relationship with automotive companies.

High Consistency

When a car is carefully designed and put into mass production, every car that rolls off the production line must maintain a high degree of consistency in structure. Its functions, durability, and performance must all meet the expected standards. Consistency is crucial when producing exactly the same products. One of the major advantages of injection molding is its high consistency. Injection molding is achieved by creating a mold. Once the mold is determined, all the plastic parts manufactured using this mold will be exactly the same. This ensures that a stable and highly consistent product can be obtained every time.

Cost-effectiveness

Custom injection molding is highly cost-effective. After creating an injection mold for the required plastic parts, the mold can be reused for production until the required number of parts is produced. In the subsequent production process, only raw materials need to be invested. Manufacturing plastic parts using the injection molding process not only has low operating costs but also results in less material waste. This characteristic of low operating costs can effectively relieve the cost pressure faced by the automotive industry.

High Precision

The high precision of the injection molding process is one of its most outstanding advantages. With this high precision, plastic parts manufacturers can confidently produce parts according to the given specifications. Once the mold is processed for automotive parts, its dimensions are fixed, and the precision is guaranteed.
