Granger Plastics Company Celebrates 32 Years of Rotational Molding Innovation
Sep 22, 2026
Ohio manufacturer marks more than three decades of engineering, manufacturing and custom rotational molding while continuing to invest in the industry's future.
Middletown, Ohio, United States, September 22, 2026 /MarketersMEDIA/ -- Granger Plastics Company is celebrating its 32nd anniversary this month, marking more than three decades of growth, engineering innovation and custom rotational molding since the company's founding in September 1994. During that time, the company has expanded its capabilities while remaining focused on solving challenging manufacturing problems for customers across a wide range of industries.
What began as a rotational molding operation serving custom manufacturing needs has developed into a full-service organization supporting OEMs, manufacturers, engineers and product developers. Today, Granger Plastics Company provides integrated services spanning product development, design and engineering, mold and tooling fabrication, rotational molding, secondary trim and assembly, packaging, warehousing and fulfillment.
Throughout its history, Granger has focused heavily on custom applications, including large, complex and demanding rotationally molded products that require close coordination between design, tooling and production. That experience has resulted in products and solutions serving industries ranging from aerospace and defense to material handling, transportation, infrastructure, environmental applications, safety products and other specialized commercial and industrial markets.
For Granger, 32 years in business represents more than longevity. The company's continued growth has been driven by an engineering-centered approach to manufacturing and a willingness to tackle projects that require unconventional solutions, specialized tooling or unique production methods.
Granger's vertically integrated capabilities allow customers to work with a single manufacturing partner through multiple stages of product development. Engineering considerations can be addressed before tooling is constructed, molds can be fabricated and modified in-house, and manufacturing and secondary operations can be coordinated as part of the overall production program.
Those capabilities continue to support Granger's emphasis on custom rotational molding for OEMs and manufacturers seeking durable plastic components engineered around specific performance requirements. The company's experience allows customers to address design, tooling, production and finishing considerations as part of a coordinated manufacturing process.
“Thirty-two years in manufacturing doesn't happen by standing still,” said Shawn Cravens, General Manager of Granger Plastics Company. “We've continued to grow by taking on difficult projects, investing in engineering and manufacturing capabilities, and finding solutions when the standard answer wasn't good enough. As we enter our 33rd year, that same mindset continues to guide where Granger goes next.”
Granger's 32nd year has also included a significant expansion of the company's educational presence within the rotational molding industry. In August, the company announced the launch of RotationalMolding.com, an expanding technical and educational resource designed to make practical information about rotational molding more accessible to engineers, manufacturers, OEMs, product designers and others evaluating the manufacturing process.
The website brings together information covering the rotational molding process, product design, mold construction, materials, manufacturing considerations, product applications and other technical topics informed by decades of real-world production experience. Additional technical articles, manufacturing guides, application information and educational content are planned as the site continues to expand.
Rather than serving solely as a corporate website, RotationalMolding.com is being developed as a long-term industry resource. The initiative reflects a broader goal for Granger as the company begins its 33rd year: combining accumulated manufacturing experience with continued investment in engineering, education and future product development.
While the anniversary provides an opportunity to recognize the company's history, Granger remains focused on what comes next. New products, evolving performance requirements and advances in engineering continue to create opportunities for rotational molding across established and emerging markets.
Granger intends to continue investing in the knowledge, equipment, tooling capabilities and manufacturing experience required to address those opportunities. After 32 years, the company's underlying objective remains much the same as it was when Granger began in 1994: solve difficult problems, manufacture quality products and develop solutions that exceed customer expectations.

SK hynix showcases next-generation AI memory technologies beyond HBM
SK hynix said Friday that it has showcased its next-generation artificial intelligence (AI) memory technologies aimed at expanding the boundaries of AI infrastructure beyond conventional high-bandwidth memory (HBM). The company presented the technologies at the OCP Global Summit 2026, held in California from Tuesday to Thursday (local time). The summit is an annual conference organized by the Open Compute Project Foundation that brings together engineers and industry leaders. The Korean chip giant said it divided its exhibition space into two sections. The front section, dubbed the memory section, showcased the company's flagship products, while the larger rear section, called the system demo section, featured memory solutions designed to support next-generation server ecosystems.

The US$82,000 Illusion: Why Bitcoin still trades like a traditional tech stock
Bitcoin currently trades at US$82,231.14, reflecting a 0.65 per cent gain over the last 24 hours. This movement mirrors a broader 0.84 per cent rise in the total crypto market capitalisation. Having operated in this industry for over 15 years and advised on blockchain policy, I view this price action as a clear reflection of […] The post The US$82,000 Illusion: Why Bitcoin still trades like a traditional tech stock appeared first on e27.
Hong Kong builds a test track for robots that keep failing outside the lab
Every humanoid robot looks brilliant in a launch video. The trouble begins on an ordinary weekday in a warehouse, when a parcel arrives in a shape nobody trained the machine for, a forklift reverses where it shouldn’t, and a worker strolls into its path while scrolling a phone. That messy gap between the lab and […] The post Hong Kong builds a test track for robots that keep failing outside the lab appeared first on e27.

Your ESOP is a fundraising document. Most founders treat it as a HR perk
Almost every founder I meet reaches the same conclusion at roughly the same moment. You cannot outbid a funded competitor on salary, so you give people a stake in the outcome instead. The logic is sound. Equity turns salary-limited hires into owners and aligns the people doing the work with the value they create. Then […] The post Your ESOP is a fundraising document.

Employers are buying AI tools. Their managers are being left behind
Thirty-seven per cent. Eleven per cent. Those two numbers, tucked deep inside Jobstreet by SEEK’s Singapore Workplace Culture Study 2026, may say more about the region’s productivity problem than any headline about AI or inflation. The first is the share of employees who try to manage workplace pressure by quietly drawing their own boundaries: muting […] The post Employers are buying AI tools.

Before you use predictive AI, decide what decision it should change
A lot of startup advice about predictive AI starts too early. It starts with the model, the tool, the data stack, or the dashboard. Those things matter, but they are not the first question. The first question is simpler: what decision should this prediction change? If a startup cannot answer that clearly, it is usually […] The post Before you use predictive AI, decide what decision it should change appeared first on e27.
'AI artists' perform improvised jazz at Jarasum Jazz Festival
Artificial intelligence (AI) models developed by a research team led by Korea Advanced Institute of Science and Technology (KAIST) professor Nam Ju-han made their debut at one of Korea’s leading jazz festivals, performing improvised jazz alongside human artists. According to the university Friday, the team showcased human-AI music collaboration technology that analyzes the flow of human performances in real time, allowing AI to take over performances or generate improvised accompaniment, during the 23rd Jarasum Jazz Festival, held in Gapyeong County, Gyeonggi Province, from Oct. 9 to 11. A total of 12 human jazz artists participated in the event, collaborating with AI in 26 pieces across 12 performances. The technology is different from existing music AI services as it enables collaboration with human musicians in jazz, a genre characterized by improvisation. Jazz musicians often change the tempo or create new melodies based on how they feel in the moment. Because the same piece can be performed differently each time, musicians must listen to one another and adjust their playing accord
