Plastics Technology

Plastics Technology is a monthly trade magazine and media brand for plastics processors, based in Cincinnati, Ohio, and published by Gardner Business Media at ptonline.com. Launched in 1955, it marked seventy years of publication in 2024, making it one of the longest-running journals devoted to plastics processing. The magazine serves custom and captive processors, the companies that mold, extrude, blow mold and thermoform plastic products, with authoritative content on processing practices, troubleshooting, technology and market intelligence. Its editorial team reports from plants around the world on injection molding, extrusion and compounding, blow molding, thermoforming, recycling and additive manufacturing. Through the print magazine, digital media, research and live conferences, Plastics Technology aims to give processors information they can apply immediately to run their operations more efficiently and profitably.

First Issue in 1955

Plastics Technology published its first issue in 1955, announcing itself as a new industrial magazine for the technical people of a young plastics industry. Its founding editor addressed the publication to readers in production, research, development, sales service and management, at a time when the field was small and close-knit: resin companies often developed applications, processes and even equipment, machinery firms sometimes sold raw materials, and a small processor had to be a jack of all trades. A magazine could credibly serve suppliers and processors together. The first cover declared new fields to conquer, capturing an era when new polymers seemed to arrive constantly. The magazine's fiftieth anniversary retrospective in 2005 revisited that debut and noted how the mission had narrowed and deepened as the industry specialized around processing itself.

Two Owners in Seventy Years

Unusually for trade publishing, Plastics Technology has had only two owners. It was first published by Bill Communications of New York, part of VNU Business Media. In August 2000, Bill Communications sold the Plastics Technology group to Gardner Publications of Cincinnati, now Gardner Business Media, in a transaction that included the magazine, its processing handbook and buyer's guide, the Plaspec database products, the PT Online website and interests in a Latin American plastics trade show. At the time of the sale the monthly magazine had a controlled circulation of about 41,000 engineers and processing professionals. Gardner, founded in 1928 with Modern Machine Shop, brought a manufacturing focus that matched the title. Its editors have credited that ownership stability, shared by few surviving plastics magazines, for the brand's continuity of mission and staff.

Editorial Leadership and Expertise

Since 1981 the magazine has had only two chief editors: Matthew Naitove, who held the role from 1981 to 2009, and Jim Callari, who succeeded him and led the title through its seventieth anniversary year. That continuity is rare in business media and shapes the magazine's voice, which is technical, plant-floor oriented and skeptical of hype. The publisher states that its editorial team holds more than 150 years of combined industry experience, and its method is reportorial: editors visit processing plants around the world to document best practices at work rather than relying solely on press releases. Coverage is organized around the problems processors actually face, including cycle time, scrap, energy, tooling, materials drying and handling, process control and workforce skills.

Coverage Across Processing Technologies

The magazine's scope covers the major plastics processes. Injection molding, the largest segment, receives coverage of machines, molds, robotics, process optimization and scientific molding methods. Extrusion and compounding coverage addresses sheet, film, pipe, profile and pellet production. Blow molding and thermoforming serve packaging and industrial parts producers, while recycling coverage has grown as processors incorporate reclaimed material and regulators and brands demand recycled content. Additive manufacturing is also covered as it moves from prototyping into production. Materials reporting follows resins and additives, and the magazine's long-running pricing and market intelligence helps processors understand input costs. Regular features with names familiar to readers, including troubleshooting columns and plant visit reports, translate that breadth into usable, specific guidance.

Gardner Business Media and the Manufacturing Portfolio

Parent company Gardner Business Media, headquartered in Cincinnati, describes itself as North America's leading publisher of integrated media for durable goods manufacturing. Founded in 1928 with Modern Machine Shop, its portfolio spans CNC machining and metalworking, plastics processing, mold manufacturing, composites, finishing and automotive manufacturing, delivered through magazines, trade shows, conferences, digital media and market intelligence. Plastics Technology fits logically beside Gardner's moldmaking title: molds are where metalworking and plastics meet, and the company has noted that owning titles on both sides of that trade motivated its moldmaking coverage. For advertisers and readers, the portfolio offers a view of manufacturing as an connected whole rather than isolated trades.

Conferences and Live Events

Beyond print, Plastics Technology runs successful annual Molding and Extrusion conferences, cited by the publisher as part of its mission to deliver actionable content in person as well as in print and online. These events gather processors for technical sessions on the same subjects the magazine covers, with plant-proven speakers and time for peer exchange. Gardner also operates wider manufacturing events and publishes research, including capital spending surveys and a monthly business index for durable goods manufacturing, that give plastics processors context on investment conditions. Webinars archived on the website extend conference-style education year-round. For a readership of plant managers and engineers who rarely leave production for long, focused technical conferences are a significant professional resource.

Digital Presence at PT Online

The magazine's website, ptonline.com, publishes its articles, product announcements, columns and market coverage continuously and hosts newsletter subscriptions and webinar archives. Digital delivery suits the troubleshooting nature of much of its content: a processor facing a molding defect at midnight can search decades-informed guidance rather than waiting for an issue. Newsletters segment content by process interest, and the site solicits contributions, press releases and case studies from readers and suppliers under published submission guidelines. The digital archive also carries the magazine's anniversary histories, including its fiftieth and seventieth anniversary retrospectives, which serve as concise histories of the processing industry itself. Print remains monthly, but the brand's daily working presence is now online.

Audience: Custom and Captive Processors

Plastics Technology addresses plastics processors directly, meaning both custom molders and extruders who manufacture for customers, and captive operations that process in-house for a parent company's products. Its stated mission is to generate content readers can use in the here and now to improve the efficiency and productivity of their businesses. That audience definition excludes much of the plastics value chain, such as resin production and product design for its own sake, in favor of the conversion step where material becomes parts. The narrowing that began as the industry specialized is now the brand's strength: owners, plant managers, process engineers and technicians in processing firms know the magazine is written for their side of the fence, in the language of machines, molds and materials.

Handbooks, Guides and Reference Products

The magazine has long been accompanied by reference publishing. When Gardner acquired the group in 2000, the transaction included the Plastics Technology processing Handbook and Buyer's Guide, an annual directory, and the Plaspec database product line, which carried information on plastics processing facilities and resins. Such products served a different need from the monthly magazine: they were kept on office shelves and consulted when a processor selected equipment, materials or suppliers. The buyer's guide tradition continues through the brand's online product and supplier coverage. Together, the magazine, handbook heritage and digital directories made Plastics Technology a small information system for processing plants, combining monthly education with standing reference data, an approach Gardner has applied across its manufacturing portfolio.

Survival in a Shrinking Trade Press

The magazine's seventieth anniversary editorial observed that only three independently published monthly magazines still serve the United States plastics market in print, a contraction its editor attributed to industry maturation, consolidation among chemical and machinery companies and the general decline of trade publishing. Against that backdrop, seventy years of continuous publication is itself the story: stability of ownership, only two chief editors since 1981, and a tight focus on processing practice kept the title essential to its niche. Plastics processing remains a vast manufacturing activity underpinning automotive, medical, packaging, construction and consumer goods production. As processors contend with automation, sustainability mandates and workforce shortages, Plastics Technology continues the role it assumed in 1955, reporting from the plant floor on how plastic products are made better.
