Parts Manufacturing

In 2017, a total of 272.48 million vehicles were registered in the U.S.  Each of these vehicles requires a vast number of parts to function and operate.  With over 30,000 parts found in a single car, motor vehicle manufacturers rely on key suppliers to assist in bringing these parts to market and to manufacturing assembly lines.

The automotive parts manufacturing industry includes those companies primarily engaged in manufacturing motor vehicle parts.  Parts manufacturing is the largest sector of the entire automotive industry.

Demand for auto parts is driven by these three core areas:

• OEM

  Original equipment manufacturers (OEM) supply parts for the production of new vehicles.  Parts are continually arriving to the motor vehicle assembly line for new car production.  The right parts have to be in the right place at the right time for the assembly line to continue operating efficiently.

• Replacement parts

  Replacement parts are made by the same manufacturer as the new car parts.  As the overall quality and reliability of automobiles have increased, the demand for parts only grows larger.  Most car manufacturers will keep stamped out body parts for up to 10 years after a vehicle has been produced.

• Aftermarket parts

  Any part of the vehicle not sourced from the original car manufacturer are aftermarket parts.   Aftermarket consumers rely heavily on parts suppliers, with over 70,000 meeting up at the SEMA show in Las Vegas.

There are over 5,000 companies operating within this industry, with 7 out of 10 manufacturing motor vehicle parts.  See the image below from the U.S. Bureau of Labor Statistics (BLS), highlighting where the majority of these parts manufacturers operate.

 

At any given time, an assembly line can have up to 6,000 parts traveling on it.  When you think about it, parts that help make subparts, which ultimately produces the part we all need in our lives: a working vehicle.  Without parts, there is no vehicle. Let us take a look at each sub-industry within parts manufacturing.

Automotive Components

As mentioned above, the manufacturing of the automotive parts that go into vehicles is vast, ranging from gasoline engines to seats, brakes, and electrical systems.  Essentially, an automobile is a complex web of systems, parts, subparts, and components assembled into a final product.

The U.S. Census Bureau has created an excellent interactive tool for visualizing all the parts that make up a vehicle.  See the image below or click here for the tool.

Major product categories for this industry consist of a number of sub-industries.  We highlight each one’s NAICS number, percentage of the overall industry, and the key products made within each sub-industry.

Economic Impact of Auto Parts Manufacturing

The automotive parts industry is a key contributor to the U.S. economy.  Virtually all automotive manufacturers produce their own parts.  However, over the years, manufacturers have been turning to first-tier suppliers for the production of just-in-time components.  For this reason, many parts suppliers are now as global as the vehicle manufacturers themselves.

IBISWorld reports that total revenue for the parts industry is anticipated to reach reach $73 billion in 2019.  It has nearly doubled since 2009 in terms of exports.  Since 2003, the overall revenue number has grown, up an almost unbelievable 506% from 2003 to 2013!  See the image below.

Most automotive exports are sent to Canada, Mexico, and the European Union.

In addition, the global automotive parts industry is expected to grow around 3.6% and ultimately reach a market valuation of roughly $466 billion by the end of 2025.

As we mentioned on the Vehicle Manufacturing page, worldwide motor vehicle production has been increasing for decades.  Well, you need parts in vehicles, which helps explain why the worldwide demand for parts is increasing.  Another positive is that parts production is increasing overall production in the U.S., see below.

The U.S may not be producing as many passenger vehicles, however, jobs are being created from the manufacturing of automotive parts.

Virtually all automotive manufacturers produce their own parts.  However, over the years, manufacturers have been turning to first-tier suppliers for the production of just-in-time components.  For this reason, many parts suppliers are now as global as the vehicle manufacturers themselves.

Key Companies

As you know by now, companies in this industry manufacture automobile parts.  They operate as either small parts plants, with a relatively small number of workers, to enormous assembly plants that employ thousands.  Approximately 49% of motor vehicle parts manufacturing jobs are in establishments employing 500 or more workers.

It's a long supply chain of parts.

Automotive News highlights the top 100 global OEM parts suppliers. Here is a look at some of these employers:

Employment Numbers

The automotive parts manufacturing industry remains a steady employer for many American workers.  The Motor &Equipment Manufacturers Association (MEMA) highlighted back in 2017 that automotive parts manufacturing jobs in the U.S. have risen 19% since 2012.  That ultimately means a steady paycheck for many and an increased need to keep these workers safe, which we discuss more below.

Taking a look at the official BLS website, there are roughly 588,000 people employed in the automotive parts manufacturing industry.  However, combined with indirect employment, the number jumps to over 4 million.  When you take a look at the next image, you can see how parts manufacturing has been on an upward slope the past decade, with growth coming in as MEMA highlighted.

Some might argue that the extreme growth occurring is only a rebound from the drastic decline in employment during the 2008 financial crisis. While there may be some truth to that, the fact remains:  the U.S. employs a lot of workers in this industry.  Here is a look at the occupations found in this industry.

"Think before you act. Safety first."

Creating automotive parts involves many workplace hazards, which means it is imperative that workers think before they act.  Workers must pay close attention to what they’re doing, no matter what task is being performed, or someone is going to get hurt.

In 1985, one Chicago parts manufacturing company had 41.8 injury cases per 100 full-time employees, roughly four times that of the industry.  Well, that number has come down significantly over the years as better safety processes have been implemented, plant inspections have increased, and newbb电子 technology has been worn.

The parts manufacturing industry, NAICS 3363, experiences around 22% more injuries than the average for all industries.  However, when you peel the onion back on this industry, tne sub-industry today that should still take safety and newbb电子 rather seriously is the motor vehicle stamping industry. 6.3 injuries occur for every 100 employees, which is 36% higher than the average for all parts manufacturing sub-industries.  It is 50% higher than the 3.2 average for all U.S. industries.  High ANSI cut-resistant gloves should be worn by the majority of workers, and definitely by those handling sharp metal materials.

Companies that make safety a high priority and embrace safe working conditions are much likelier to avoid workplace injuries.  newbb电子平台 Safety places a high priority on safety – it’s what we do. We Protect People!

As the automobile industry adapts to future technologies and new parts, newbb电子平台 Safety will be there evolving along the way, adapting newbb电子 to fit the employees’ needs and keeping automotive workers safe at work.

Let us help keep you safe!
