13 Business Ideas for Mechanical Engineers

Mechanical engineers design, develop, build, and maintain mechanical systems. With their skills, they are able to easily solve problems and introduce innovations. Such skills are also crucial in running a business.  

We’ve come up with a list of business ideas for mechanical engineers. If you’re a mechanical engineer looking to set up your own business, then consider starting a heavy equipment business or an insulation business. Go through the list and see if anything inspires you.

1. Insulation Company

Insulation Business

Here’s an idea for your next venture: why not start an insulation business? It’s a growing industry with plenty of opportunities. The global insulation market has been growing nearly 5% since 2018.It is projected to reach close to $80 billion in revenue by 2026. Depending on the type of material used, insulation can lower heating and cooling costs. It can also be used to soundproof rooms and provide protection from fire.

When starting your insulation business, it is important to know the various types of insulation, how it works, and what laws and regulations are applicable. It’s also a good idea to scope out the competition and find out what services are available in the market. To differentiate your business from the thousands of insulation contractors in the US, you will need to provide better services and make sure to use quality materials. With a strong marketing campaign and by properly engaging with your potential customers, you can build awareness about your business.

2. Heavy Equipment Business

Heavy Equipment Business

Now that the economy is recovering and construction activities are picking up, starting a heavy equipment business is a good idea. Heavy equipment refers to heavy-duty vehicles designed mostly for use in construction, especially earthwork operations. The US construction industry is expected to boom at all levels and the construction equipment market is anticipated to grow 6% per year through 2027. 

Before starting your heavy equipment business, make sure first that you have the capital for your inventory and the permits required for your operations. You’ll have greater chances of succeeding if you study the market, find a niche that you can dominate, and carefully select the brands that you will carry. Unless you simply distribute known heavy equipment brands, you’ll need to be creative with your marketing and target the right prospective clients. Starting a heavy equipment business can be a daunting task. But, with the right planning and execution, it can be a lucrative and exciting venture.

3. Scrap Metal

Scrap Metal

Are you looking for a business opportunity that is both profitable and sustainable? If so, starting a scrap metal business may be the perfect option for you. Scrap metal is in high demand worldwide, and there are countless ways to turn a profit in this industry. In the US, scrap metal recycling is a P50 billion market and still growing. 

Getting started with scrap metal recycling can be a challenge. There are fees to be paid, licensing and insurance requirements to be completed, and regulations to be followed. It’s to your advantage to find a suitable location for your scrap yard and make sure it complies with zoning regulations. It’s also a good idea to research the market and find out what other scrap yards are offering as well as the type of equipment they’re using so you can devise a way to gain a competitive advantage. Recycling scrap metal normally involves sorting, shearing, shredding, torching, and baling. The scrap metal is then sold to metal smelters for further processing.

4. Solar Panels Installation

Solar Business

Are you thinking of starting a solar business? If so, you’re in good company. Thanks to government incentives and greater concern about the environment, the solar industry is booming, and the cost of panels has declined more than 60% in the past decade. To top it off, there’s probably never been a better time to go into business for yourself. 

Before you get started you’ll have a big decision to make: which aspect of solar power your company will concentrate on. You could sell solar panels, install them, sell and install, or go in another direction and build an entire solar farm. That last choice is of course the most expensive, and also requires a sizable chunk of land, preferably in a sunny place. Whichever option you choose, you will need to meet all the licensing and regulations requirements, and after that you’ll be ready to renew and energize your entrepreneurial journey.

5. Tutoring


Do you have an area of academic expertise? Maybe you’re great at math, deeply familiar with science, or obsessed with language and literature. Even if you’re not a subject expert, but simply good with children, now’s a great time to consider starting a tutoring business. 

The industry took a hit during the pandemic, but today many tutors are embracing virtual instruction and tutoring is expected to see steady growth in the years ahead. As a result, you’re now able to run a tutoring business almost entirely from home, all while helping children to learn and excel and making a good living.  

Starting a tutoring business is not terribly complicated. If you have teaching experience or some proof of your expertise, you mainly need a good computer and you can start offering your services on a variety of online platforms, like ClubZ or eTutorWorld. With a bit of marketing on social media, you should be able to attract a few clients and start building your tutoring empire.

To get a share of this lucrative market, you will need to keep up with the latest technologies, diagnostic software and tools to assess vehicles.

Before launching your business, you will need to check out the licensing and zoning requirements. Generally, a mechanic needs to finish high school and undergo an in-depth training or certification program. Once you comply with government regulations, it is important to research ways to differentiate yourself from the competition. Remember that there are hundreds of thousands of repair shops across the country. Although the industry seems to be saturated, there are still many ways for you to succeed. An option is to find an underserved location, set up your shop there, and work very hard.

It’s not as difficult as you might think – but there are a few key things you need to know first. You should first research the market and see which items have been doing well. Is it pepper spray and stun guns? Or maybe personal alarms are doing well right now. Once you nail down your product line, partner with a dropshipper who will manufacture and ship your products directly to customers as needed. Finally, develop some strong marketing to highlight the effectiveness of your goods, and you should soon be doing steady business.

8. Yard Sign

Yard Sign

One of the many industries altered and reshaped by the pandemic was yard signs, also known as yard cards.

You could start your own yard sign business and take advantage of this trend to sell signs on politics, society, sports, and health. In addition, as the pandemic recedes, more and more people are organizing long-delayed social gatherings. This means the demand for yard signs related to birthday parties, weddings and graduations is set to increase. With a good laptop and quality software, you could start your yard sign business at home and choose your own hours. 

You’ll just need to find a reliable, affordable printing firm to partner with, market yourself to stand out from the competition and, when given the chance, deliver excellent products and services. That’s a recipe for success!

Manufacturing Business

A great deal of manufacturing has moved overseas in recent decades, but US manufacturing is still an $8 billion industry that has seen steady growth in recent years. Manufacturing businesses can be extremely profitable, but they also require a lot of planning and hard work.  

The first step is to decide what you’re going to produce. Do some market research and see which products are selling well and where there may be a market gap. You should keep an eye out for products that are more affordable to manufacture or offer a significant markup and strong profits. Next, you’ll need to rent or purchase a manufacturing facility, preferably in an out-of-the-way location to keep costs low. Once you start making your products, you’ll need to have them tested and certified and acquire all the necessary licenses and permits. 

Finally, you’ll be ready to launch a marketing campaign that, with a bit of luck, should start bringing in orders and put you back in the black.

Even if you don’t have experience, it’s easy and inexpensive to take an online course and learn how to be a locksmith. After that, you might want to partner with an established locksmith in your area to gain some real-world experience. Once you’ve built a reputation, you could strike out on your own and start offering your services, providing keys, safes, locks, doors and even security systems. 

As long as you provide excellent service, you’ll have success all locked up!

Small Engine Repair

More than 8,000 job openings for small engine mechanics are projected in the US each year through 2030. They work in auto repair shops, or do onsite repair calls.

But first, do your research and look at the industry trends and the competition, figure out what kind of equipment you need, and how much it will cost.

Keep in mind that using replacement parts may alter the coverage of an insured item.
