The Industry 4.0 era of manufacturing depends so heavily on data-driven precision that artificial intelligence (AI) is playing an increasing role in harnessing that data to enhance the performance of machines — including injection molders.
Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.
“AI is becoming increasingly important in mechanical engineering, not least because of the need to automate injection molding processes efficiently and flexibly despite ever smaller batch sizes and shorter product life cycles,” said Werner Faulhaber, Director of Research and Development at Arburg. “Application examples of AI include automatic programming of robotic systems, targeted malfunction remedying, and a spare parts system with ‘intelligent’ image processing. Arburg is working on making injection molding more intelligent, step by step — ensuring that the machine continuously learns, keeps itself stable, and can even optimize itself in the future.”
One application Arburg is working on is the automatic programming of its Multilift linear robotic systems. “The idea is that the operator simply enters the destination, as with a car navigation device, and the system automatically calculates the optimal route. For robotic systems, this means that the operator simply enters the desired start and end positions, and the control system takes care of the rest.”
NPE2024: BASF is using its proprietary computer-aided engineering tool Ultrasim when designing for sustainability in a broad range of industries.
Wittmann Battenfeld, which has fully embraced Industry 4.0 connectivity across its portfolio of injection molding and auxiliary machines over the past several years, employs AI with its robots to monitor cycle times and control robots’ speeds outside the molding machine.

Arburg uses AI “to develop master models using experience and data collected over the years on process, material, and machinery,” Faulhaber continued. “The customer could then sharpen the provided master model ‘on edge’ and optimize their processes. The in-house development Gestica control system, the Arburg host computer system, and the arburgXworld customer portal give an advantage here.
High density, resistance to temperature fluctuations, ceramic feel and sound, and a glossy, smooth surface are some of the material’s characteristics, which are important for luxury brands. Sulapac Luxe is not only recyclable, but as with all Sulapac materials, it can also be made with recycled content, another feature important for many premium brands. Said Haimi, “Sulapac is a pioneer in recycled bio-based materials and our aim is to use only recycled biopolymers within the next five years.” She noted that several high-end beauty brands have already shown interest in utilizing Sulapac Luxe in combination with their existing glass fragrance bottles or jars. The material is commercially available to all manufacturers and slips seamlessly into existing injection molding production lines.
August 29-30 in Minneapolis all things injection molding and moldmaking will be happening at the Hyatt Regency — check out who’s speaking on what topics today.
Recently the company launched two new injection molding materials reportedly ideal for replacing hard plastics such as ABS and specifically developed for conventional plastics converting machinery. Sulapac Luxe, made of sustainably sourced biobased biodegradable biopolymers and wood flour, is said to be ideal for fragrance bottle caps, lids and cosmetic jars. “It’s the only material in our cosmetics portfolio with fine, non-visible wood,” notes Haimi.

Another Wittmann feature, Eco-Vac conserves energy by setting a few parameters on the robot and allowing the robot to turn its vacuum circuits off and on. “The robot monitors the vacuum level of the circuit used for picking the part out of the mold. If the robot senses the vacuum has reduced to a level that it could drop the part before it is told to, the robot will turn the vacuum on until it reaches the safe level again, then shuts back off.” This feature cuts the amount of compressed air each robot uses “and could save customers hundreds of dollars a year per robot.”
The aim of this presentation is to guide you through the factors and the numbers that will help you determine if a robot is a smart investment for your application. Agenda: Why are you considering automation? What problems are you trying to solve? How and why automation can help Crunch the numbers and determine the ROI
A more flexible edition, Sulapac Luxe Flex, comes without the wood component. This is a more ductile material with exceptionally good flow properties, and is ideal not only for caps and lids but also for compact powder boxes and other complicated designs. Sulapac Luxe Flex has a flexural strain of 10%. Both Sulapac Luxe and Luxe Flex can be used to replace ABS. “They have many similar properties, yet the Sulapac materials leave no permanent microplastics or toxic load behind during the use phase or in the end of life,”says Haimi.
Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.
Plastics processors are finding applications for 3D printing around the plant and across the supply chain. Here are 8 examples to look for at NPE2024.
With the expanded portfolio, Sulapac’s customers can now create packaging for various product areas, including skincare, makeup, and fragrances. Shiseido’s brand Ulé utilizes Sulapac for their lids, while a diverse group of skincare brands from Lumene to Manik package their products in Sulapac jars. The selection of materials and production techniques allows brands to choose between a matt, glossy, or natural appearance complimented by a wide range of color options.
As AI and machine learning are further leveraged to improve injection molding operations, simply gathering data is not enough to optimize processes, Faulhaber cautioned. “You also need the process expertise and domain knowledge. In the future, the evaluation of many data directly in the control unit will offer further added value.”
“One major challenge beauty brands face in replacing conventional plastics is the strict performance criteria of the chosen materials,” said Sulapac’s international sales director Colin Strobant. “With Sulapac Luxe, we have shown that conventional plastics can be easily replaced without compromising on quality. We have listened to our customers’ challenges, and the material has been through an extensive development process to ensure it stands up to the highest demands for luxury performance.”
AI in manufacturing encompasses an array of technologies that allow machines to perform with intelligence that emulates that of humans. Machine learning and natural language processing help machines approximate the human capacity to learn, make judgments, and solve problems. Data-enhanced efficiency keeps processes moving faster and more cost-effectively.
The successful launch of the BetterBarrel by Schwan Cosmetics last year, and Toly’s popular Infinity Line of powder compacts made with Sulapac further demonstrate the versatility of Sulapac’s offering. Sulapac has also developed premium quality solutions in collaboration with Chanel, including sustainable bottle caps created exclusively for the fragrance range Les Eaux DeChanel and the lid for the N° 1 de Chanel Cream.

Wittmann co-funded such an assessment program with Austria’s Montanuniversität Leoben university, “but we found that the time needed to make it workable for production had to be questioned because in addition to the long-term investigation of the process, you also need the manpower necessary to handle it.”
Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.
Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.
As noted by Haimi previously, “Sulapac’s business model is based on partnerships and factor in as a service concept, meaning we do not own any production facilities but partner with existing production plants. This business model enables localized manufacturing of the end-products, and as our business grows, also the material production can be taken close to the customer.”
