In 2021, Al-Sheyyab and his team began an extensive study with Anybrid on thermoplastic extrusions, composite profiles and molded parts. By late 2022, they had successfully overmolded profiles offline but also integrated a ROBIN unit into a production line at the REHAU technical center, where profiles were overmolded in-situ.

“We developed this robotized injection molding machine in 2019 to produce hybrid components,” says Michael Stegelmann, managing partner at Anybrid (see “Robotic injection molding for functionalize composites”). “Hybrid components” refers to functionalizing a structure with an injection molded polymer to create local attachment points, stiffening ribs, etc. This overmolding process has gained traction in composites, but typically uses a traditional injection molding machine.

“Dongnam sent us some of their pelletized materials and we did overmolding tests using ROBIN,” says Stegelmann. “The materials processed really well and create a whole new possibility of generating functionalized biocomposites for furniture or consumer goods that eliminate the need for petroleum-based plastics. We see a lot of potential for using ROBIN with these cellulose polymers in the future.”

The expertise of both teams was important in these developments. “The parameters from extrusion have to be brought together with those from injection molding,” says Sell. “It is important to match the speed of the production line to that of the part to be overmolded. For example, the cooling time of the overmolded element must be taken into account.”

In-house metalworking capabilities include engineering design, sheet metal shearing, punching and bending, roll forming, hardware integration, welding, grinding, polishing, painting, and assembly. Summit’s thermoplastics engineering expertise allows the company to process multi-shot and bi-injected tooling and perform insert overmolding. Pad printing, hot stamping, ultrasonic welding, and assembly are also offered by the company, which operates a 26,000-square-foot facility northwest of Chicago in McHenry, IL.

Although the print bead is constant for each print, it could be 4-24 millimeters wide and 1-5 millimeters tall. That rough surface creates issues with achieving a good seal for the ROBIN mold and runout of the injection material during overmolding. “Thermoforming provides a smooth surface, and we also achieve a good connection between the overmolding and substrate materials,” says Stegelmann (Fig. 3).

“The use of composite materials in structural applications creates specific challenges for joining,” explains Stegelmann. “ROBIN can be added to production lines to integrate inserts that enable attachments and facilitate assembly [Fig. 1]. Anybrid has demonstrated this in two projects with the Innovation Group of REHAU Industries [Rehau, Germany]. REHAU produces polymer-based solutions for construction, automotive and industrial applications including window profiles and components for car exteriors, bumpers and air duct systems. REHAU is also researching a variety of innovations using composites, including natural fiber and bio-based composites.”

The printed structure was then overmolded using polypropylene (PP) with 30% glass fiber supplied by Mitsui Chemicals (Tokyo, Japan). “The black PP compound allowed us to see the material flow onto the 3D-printed PLA substructure,” says Stegelmann. “We quickly preheated the 3D-printed surface using an infrared heater and then closed the ROBIN mold onto the panel, thermoforming the part surface. This thermoforming is needed due to the large bead size of the printed materials.”

The composites industry plays a crucial role in developing lightweight and durable materials for a range of applications, including those critical to national defense. One key focus area is the development of advanced structural materials and manufacturing technologies that support next-generation space, missile and aircraft systems for the U.S. Department of Defense (DOD). ARC Technologies LLC (ARC), a division of Hexcel Corporation, based in Amesbury, Massachusetts, is a provider of advanced composites structures, specialty materials and other unique products that provide the U.S. Department of Defense with advanced capabilities to protect service members while in harm’s way. This team’s specialty is to understand a specific need from a program office, PEO, platform manufacturer or other offices within the DOD. With that understanding, the team can design a solution, develop a prototype for test and evaluation, perform extensive in-house testing — including electromagnetic, environmental and structural testing — and then partner with the customer through platform evaluation. The Hexcel Amesbury division has a team of engineers on staff, including mechanical, chemical, electrical and research and development specialists that can provide design, testing and manufacturing capabilities to service customer requirements from concept through production. This presentation will illustrate capabilities in advanced composites and other specialty materials structures, focusing on the Hexcel Amesbury team's niche in electromagnetic signature reduction and other unique capabilities.

Six U.S. companies have proven their recycling technologies for composites and rare earth elements, and will be supported for relevant scale demonstration and validation.

“We see great potential to use Anybrid’s mobile injection molding in a variety of continuous process lines,” says Sell, “such as thermoplastic extrusion, pultrusion or CCM, for the production of composites parts for transport or industrial applications, for example. It enables monomaterial systems — products that consist of the same polymer matrix. Steps such as gluing are eliminated. This makes production faster and the products easier to repair or recycle.”

Celebrating National Composites Week 2024, CW looks at how composites are being used to provide the next generation of energy.

Anybrid’s ROBIN demonstrates inline/offline functionalization of profiles, 3D-printed panels and bio-based materials for more efficient, sustainable composite parts.

The composites industry is increasingly recognizing the imperative of sustainability in its operations. As demand for lightweight and durable materials rises across various sectors, such as automotive, aerospace, and construction, there is a growing awareness of the environmental impact associated with traditional composite manufacturing processes.

He notes that ROBIN also saves costs. “Using the small injection molding robot makes it possible to dispense with large, expensive tools. The logistical effort is also reduced since profiles no longer have to be moved to injection molding machines. We have shown that costs can be reduced and productivity and flexibility increased in our extrusion lines.”

Stegelmann and Chauzu also emphasize that it is possible to use the process heat during reactive pultrusion instead of preheating the profile for overmolding, as is typically necessary. This would enable even better process and energy efficiency, they explain. “For example, a PA composite might be heated to 180 to 200°C,” says Stegelmann, “instead of allowing the profile to cool, we can overmold as the pultrusion exits the system to achieve a good connection, saving time and process steps. Again, overmolding is not new, we are just enabling it to become directly part of the process line, but with increased flexibility and lower cost.”

Branding these materials as Supercore, CQFD claims other advantages, including a modulus of 50-62 gigapascals — roughly 1.5 times more stiffness than conventional glass fiber composite profiles — and a density of 2.0 grams/cubic centimeter. CQFD profiles made using unidirectional (UD) glass fibers (GF) offer a higher specific rigidity versus profiles made using aluminum (2.7 grams/cubic centimeter). Also, because these profiles are thermoplastic composite, they can be thermoformed, reshaped and overmolded.

Dan Martin, President of Summit, commented: “Since my wife, Michelle, and I founded Summit 25 years ago, we’ve been committed to providing outstanding quality and customer service to build the business into a leader in the design, engineering, and construction of molds and molded components. We’ve now reached an inflection point in our growth trajectory, and we believe Fathom is the perfect fit in terms of both culture and customer-value proposition to help take Summit to the next level.”

This connection was investigated using computed tomography (CT). “We can clearly see diffusion between the two polymer systems, which creates a mechanical interlocking,” says Stegelmann. “There are still some challenges in optimizing the processing temperatures, but we see a real opportunity for in-situ functionalization of 3D-printed parts with local inserts, sealings, clips, etc. Our next step is to demonstrate this potential with a technical component from the marine industry. We can see a future where large-volume 3D printing facilities will be equipped with our mobile injection molding system as standard due to the possibilities it opens for their parts.”

This collection features detail the current state of the industry and recent success stories across aerospace, automotive and rail applications.

Stegelmann explains the steps involved: “First, we position the metal insert inside the small injection mold within the ROBIN machine [Fig. 2]. Next, the ROBIN system is aligned with the profile, and then the mold is closed and the fastener is overmolded. Because the mold is very small, ROBIN is able to reach even between the high walls on the back side of this profile and overmold fasteners with anti-twist resistance or integrated sealing, for example.”

For automotive applications, demonstrations used Lanxess Bond-Laminates (Brilon, Germany) Tepex 102-RG600 PA6 with 47% glass fiber roving for compression molding. Resulting composite profiles were then overmolded using Lanxess’ (Cologne, Germany) PA6 flame-retardant Durethan BKV60 and BKV30 with 60% and 30% chopped glass fiber, respectively. For this application, ROBIN was used to integrate threaded fasteners from Böllhoff (Bielefeld, Germany) into a narrow omega-shaped profile (Fig. 1).

Over the last 8 months, Archer Aviation has completed a total of 402 test flights with its composites-intensive aircraft, adding to key milestones.

EU project will develop bio-based, repairable and recyclable vitrimer composites and advanced sensors for highly reliable, sustainable wind blades.

“Due to the innovative composition of CQFD’s composite materials and the right process parameters, it is now possible to obtain excellent adhesion with the overmolded PA6 inserts even when using a highly fiber-filled composite,” says Frank Chauzu, founder and CEO at CQFD. “Supercore profiles are also available with compatibility for other material combinations such as PP. To reach that compatibility, the profiles go through a specific treatment developed by CQFD that promotes adhesion between the PA6 and PP materials.”

Although Anybrid works with a wide range of standard materials, the innovative nature of the technology makes it attractive for companies developing new materials and processes. One such partner is CQFD Composites (Mulhouse, France), a supplier of structural thermoplastic composite profiles. Founded in 2006, CQFD Composites has developed a reactive thermoplastic pultrusion system. This technology uses in-situ polymerization of low-viscosity caprolactam monomer to produce, in this case, PA6 pultruded profiles with high glass fiber content, up to 85% by weight.

In a second set of demonstrations, the teams used continuous glass fiber/PEI profiles produced by Xelis (Bermatingen, Germany) using its CCM process. Similar to omega-shaped stringers used in commercial aviation, Hitsert threaded inserts from Böllhoff were integrated via overmolding with glass fiber/PEI materials fom SABIC (Riyadh, Saudi Arabia). “These parts demonstrated our ability to overmold using high-temperature materials approved for aerospace,” notes Stegelmann.

The opportunity for Anybrid’s ROBIN technology to produce a variety of more sustainable composite parts seems, if not limitless, then at least very broad. “The issue is convincing companies to move beyond the known and familiar,” says Stegelmann. “Overmolding has been well proven and is gaining use in composites. We are just making that process mobile and more flexible to provide really futuristic solutions that can generate value for manufacturers now.”

“We wanted to demonstrate a process chain where CQFD’s reactive pultrusion process could be combined with our robotized injection molding inline,” says Stegelmann. The first demonstration used CQFD’s in-house GF/PA6 profiles and a black-tinted PA compound with 30% glass fiber supplied by Lanxess for overmolding. The overmolded feature (Fig. 4) is a shape Anybrid created to demonstrate the complexity that is possible with ROBIN. It also provides a good basis to test for adhesion between the overmolding and the substrate.

To demonstrate the ability to functionalize 3D-printed parts, Anybrid worked with the Institute of Lightweight Engineering and Polymer Technology (ILK) at Technische Universität Dresden in Germany. “The use of large-scale/large-format additive manufacturing [LSAM/LFAM] is growing,” notes Stegelmann. “The technology has been proven to be quite capable and cost-effective, but the problem with these big machines is they can print with high deposition rates but not with high resolution, and thus, fine details are impossible. This is where we can help, because ROBIN can overmold detailed functional elements during the print process.”
