If you are looking for quality, low tooling costs, high tensile strength, uniform wall thickness, and a single, seamless one-piece construction in a tank or other product, then a rotationally molded part is your best solution.
What is Rotational Molding?
Rotational molding is a three-stage, no-pressure, plastic molding process. During the heating stage, the mold slowly rotates in two planes (bi-axial rotation). Heat transfer causes the plastic charge inside the mold to melt and uniformly coat the interior of the mold. During the second stage, the mold moves to the cooling station, where it is cooled by air and/or water spray. In the final load/unload stage…To read more download our white paper to learn more about Rotational Molding.

Can you believe we are already in November of 2022? I don’t know about you, but for me, the last two years have been like living in a fog, with events and public opinion as framed by the media being the opposite of morally right and common sense.
When the Pilgrims landed at Plymouth Rock in 1620, the first thing they did was to pray and acknowledge God’s blessings upon them and they dedicated their new colony to Him. The Mayflower Compact was signed onboard the Mayflower, while still at sea, pledging the new colony’s obedience to God in the formation of their new “civil Body Politick for our better Ordering and Preservation, and Furtherance of the Ends aforesaid: And by Virtue hereof do enact, constitute, and frame, such just and equal Laws, Ordinances, Acts, Constitutions, and Officers, from time to time, as shall be thought most meet and convenient for the general Good of the Colony; unto which we promise all due Submission and Obedience.”
This Thanksgiving, while you gather with family, friends, and loved ones, enjoy the time you share, the joy of family and precious moments, and take a pause to recharge your soul.

America the Beautiful. Land of The Free and Home of The Brave. Baseball and Apple Pie. Hot Dogs and Hamburgers at the Park. Fireworks. The Star Spangled Banner. The Pledge of Allegiance. All of these muster a feeling in the hearts of Americans from Coast to Coast. A feeling of profound blessing to live in the Greatest Country in the history of the world.
America was founded by regular people, with a faith in The God of the Bible, who wanted to escape religious persecution and the rule of a monarch who didn’t care about the welfare of his subjects, but only about himself and his own opulent lifestyle, built on the backs of the hardworking masses.
People from England, who were told how to worship and not worship, who were persecuted and stripped of their rights as humans, ordained by God, had two choices; stay and continue to live a hopeless life under the thumb of an evil King or set sail to a New World. Untamed and unsettled. A place with overwhelming risk of survival, but a place where they could establish a society centered on the love of God Almighty, and a place where they could live by His rules, and not those of a selfish and prideful King.
They wanted to rule themselves as equals and just as the Israelites of the Old Testament did when they escaped from Pharaoh in Egypt, they trusted in God to protect them and see them through in a wild and unforgiving land…..click to download and read the rest of this year’s 4th of July Newsletter (1.44mb)

When I was a young adult in the 1970’s, the Silver Screen was rocked with the premiere of Star Wars, the epic saga of Good vs. Evil set in the future, complete with spaceships, aliens and a planet sized space station called the Death Star. There were no better unlikely heroes than Han Solo, Luke Skywalker and Chewbacca and there was no better villain than Darth Vader.
The rebels fought against overwhelming odds against what seemed an unbeatable foe with little, if any chance of success. If not for a small droid named R2D2, whom had been programmed with a secret message from none other than Princess Leia, the ruler of the planet Alderaan, to an all but forgotten old man named Obi Wan Kenobi, the rebels would be doomed to certain defeat.
Princess Leia in her message laid out the hopelessness of the rebellion against the Empire and left off with the famous line “Help us Obi Wan Kanobi, you’re our only Hope”. Why did she think Obi Wan was her only hope? Because he had the power of The Force as a Jedi Knight, an elite class of warriors of old, who understood the hidden power in the universe of Good and Evil, but focused on the Good as stewards of humanity and protectors of the oppressed………Click for an instant download of this year’s Easter Newsletter (1.56mb) –>
About 35 years ago, Peabody Engineering did a study in cooperation with California State University Long Beach Engineering Structures Lab to design a viable seismic restraint system for our polyethylene tanks.
Based on that study, we determined that the cable and post systems that were being used as an industry standard for seismic restraint of polyethylene tanks were an ineffective and unsafe design. We decided that a new design should be developed that would safely restrain plastic tanks without the potential for damaging them. Peabody does offer a cable system for our tanks if you have budget constraints, but we strongly recommend you consider one of our three other superior designs outlined below based upon the risks associated with the cable systems noted above.

With more than 40 years in the plastic tank business, you would be hard pressed to find an application we haven’t seen before. When it comes to building polyethylene tanks for custom applications, there are always unique design considerations. Our whitepaper includes important factors when configuring and specifying a special application storage tank.

Tis The Season and what we have deemed truly important are the little things we take for granted everyday:
Being with loved ones,
Having a career that you enjoy
Sharing a meal with family and friends
The gentle touch from someone you care about
A wet kiss from a furry four footed friend
The smell of dinner cooking
The crackling of a warm fire while savoring the refreshing taste of your favorite libation
Grandkids if you are of “a certain age”
There is so much more we could add to the list. The meaning of Christmas does not need to be flashy with expensive gifts, but rather something simple like spending time with your family, friends and loved ones, good conversations and a feast to share. These are some of the traditions that make Christmas meaningful for many people.
So while you celebrate the holiday season we hope you enjoy this year’s “Tis The Season” Christmas Letter. You can either view below and or you can download Christmas PDF Newsletter by click here (1.2mb). Whichever way you prefer to view it – we hope you enjoy it and don’t forget to share some of that Trivia around your Christmas Dinner Table!!!
For the agricultural industry, polyethylene tanks have proven to be a reliable, go-to storage solution for years because of their durability, low maintenance, and less expensive price point than fiberglass or stainless-steel tanks. For growers and pesticide application businesses, the benefits of using tanks constructed of polyethylene are numerous.
Typical Agriculture Applications
Storage and transportation of micronutrients
Storage and transportation of liquid fertilizer
Storage and transportation of pesticides and herbicides
Poly tanks are extremely compatible with many of the liquid products used in agriculture businesses. But different types of plastic resins have different chemical compatibilities. For example, linear polyethylene (LPE) might be an excellent choice for one chemical, but not compatible with another. Although LPE is great for a wide range of ag chemicals, nothing is a cure-all for all chemicals.
Ease of Use
Like all equipment and asset purchases, growers and other agriculture business owners want tanks that make their jobs easier. Polyethylene tanks are lighter weight and easy to handle, which makes it easier to move if it needs to be relocated. Many poly tanks are designed with molded-in calibration for quick level assessment. They are also available in a wide range of capacities, including large capacities that make bulk ordering of products and field storage of ag chemicals more convenient and less expensive.
Durability and Resistance
Almost all plastic storage tanks are manufactured from highly durable, chemical-resistant resins, like Linear Polyethylene Resins (LPE), which is specifically formulated for making rotationally molded plastic storage tanks. These premium resins are made with excellent UV inhibitors that help provide long term UV resistance, even in the most severe weather conditions. Poly tanks are also corrosion-resistant and won’t rust, making them perfect for today’s pesticide, herbicide and fertilizer products.
While no storage tank is designed to last a lifetime, the durable resins and added UV inhibitors used in the manufacture of polyethylene tanks can mean several more years of service. Some poly tanks can last up to 20 years or more. A tank’s longevity depends on a few things: the type of resin used, the products stored in it, and the environment it is stored in.
To prolong a poly tank service life, routine inspections to assess its structural integrity are crucial. It’s recommended to do an inspection in the spring before filling the tank with fertilizer, pesticide, or other products, and once again in the fall at the end of the growing season.
Specific Gravity Rating
Another consideration for prolonging the life of a polyethylene tank used in the agriculture industry is choosing a higher specific gravity rating. The specific gravity rating is a measure of the tank’s ability to withstand the weight of the liquid it is storing. If the tank isn’t thick enough, it will begin to bulge under the weight of a heavier product and that coils not only affect the tank service life, but also put stress on valving and piping attached to the tank. Most polyethylene tanks are rated for water only weight, standard duty and heavy duty wall thicknesses, offering the user a choice in how the tank will perform with their specific application.
The vast majority of fertilizer solutions and other ag chemicals are between 1.0 and 1.25 specific gravity and can safely be stored in a standard duty (1.5 specific gravity) rated tank. For heavier liquids, as well as products that are oxidizers or reactive, you may want to consider the Heavy Duty (1.9 specific gravity) wall, which will not only provide a stiffer wall that will minimize bulging (a normal occurrence in plastic tanks) and also offer a longer service life in a corrosive application.
Pro tip: tank ratings are assuming ambient temperatures, if you will experience higher temperatures this should also be factored into your plan.
About Peabody’s Tanks
Peabody Engineering’s roots are in the agricultural fertilizer equipment business. We understand the unique needs of the industry, and for over forty years, we’ve manufactured storage solutions for growers across the county, including our ProChem® potable water and chemical tank products, designed for agricultural and industrial chemical applications where a single-walled design is desired.
Capacities from 25 to 1500 gallons are manufactured with a premium MDLPE UV-20 rated resin, and XLPE as standard options, and are also available in PPL and PVDF for more demanding applications. Our ProChem® tanks are NSF/ANSI/CAN 61 certified (XLPE tanks 40 gallons and below are not NSF/ANSI/CAN 61 certified) and include an integrally molded pump mounting platform on top and standard process fittings for fill and discharge on most sizes. Supplied with a large, vented access opening and easy to read calibration in liters and gallons, the ProChem® potable water and chemical tank line offer standard features not previously available.
Different manufacturers use different resins with varying performance specifications. Most tank manufacturers use resins with a UV rating from 8-12 years. We are now using resins that have UV inhibitors rated for 20 years, so UV attack is much less of a factor than it once was with polyethylene storage tanks.

Happy 4th of July from Peabody Engineering! We want you to know how much we appreciate your patronage and confidence in Peabody Engineering. The world is a tough place right now and our country is not without its challenges. The Bible tells us to “Run and Not Grow Weary” and “Run the Race to Win!” Adversity is a part of life, and our character is defined in times such as these. We are halfway through the year, mile 13 of a marathon. Now is the time to dig down deep within ourselves and pull out the strength and courage that we Americans have been doing for the last 200+ years.
The 4th of July is a story about a select group of brave men and women who would not give up, despite overwhelming odds. The men under General George Washington at Valley Forge in the dead of winter, cold and hungry, rallied together on Christmas Eve and crossed the icy Delaware River to fight for what they believed in; personal freedom from the oppression of a governing authority that was unjustly taking things from Americans by force, The Freedom to work hard to provide good things for their families and a secure future. It’s also about courageous men like Patrick Henry, the first Governor of Virginia, who shouted “Give me Liberty or Give Me Death” when faced with an overwhelming problem with no visual chance of success.
This great American Courage replayed itself in every war from then right up through the war against terrorism. It is the American Spirit and character that defines us, that makes us Great. Its why God has blessed us beyond measure and why we must press on toward the goal. It is why we should NEVER, NEVER, NEVER give up and quit fighting for what we believe in.
May God Bless you and your family this Independence Weekend as you rest and reflect on your blessings as an American. Thank-you for your business, without which we would not have enjoyed success these past 69+ years in business.
