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.”

New robotic and digital technologies are enabling advanced in-house capabilities for small companies and innovative suppliers willing to embrace the move toward more affordable, sustainable composites.

“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.”

“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.

During this webinar, the audience will be introduced to a variety of fiber composite technologies — as well as the machines and equipment — from short fibers to continuous fibers, from thermoset to thermoplastic, as well as the according process technology, including a special focus on long-fiber injection (LFI) and structural composite spray (SCS). Focus markets include automotive, aviation and AAM, transportation, and construction. This webinar will provide a detailed overview of according application examples.

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.”

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.”

As global industries and markets demand increased sustainability, novel automated systems such as Anybrid’s (Dresden, Germany) robotized injection molding (ROBIN) offer a means to functionalize composite components, eliminating bonding and facilitating lightweight assemblies.

Reliable news and information on where and how fiber-reinforced composites are being applied — that’s just the start of what you get from our team here at CompositesWorld.

As explained on the REHAU Germany website, when Dr. Stephan Sell, research chemist in Al-Sheyyab’s team, first saw Anybrid’s ROBIN technology at the K trade fair in 2019, he could see many opportunities for it at REHAU. “They have succeeded in transforming the otherwise stationary injection molding machine into a mobile machine that can be moved freely in space,” says Sell. “This means that functional elements such as seals, metallic inserts, connecting elements or ribs can be retrofitted to existing molded parts, profiles, semi-finished products and metal hybrid composites.”

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.

Closed mold processes have many advantages over open molding. In this knowledge center, learn the basics and vital tools needed to produce parts accurately.

Base Materials introduces a high-performance, toughened epoxy tooling board designed for thermoforming and vacuum forming processes, direct-to-part applications and more.

“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 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).

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.”

“Mobile injection molding allows us to apply recurring elements as needed with a high degree of flexibility to profiles or large-scale components,” says Stegelmann. He points out a shell demonstrator (Fig. 2), “where we show that with overmolded omega profiles, you can achieve a very quick, simple construction to achieve light-weight, high-strength assemblies.” REHAU and Anybrid plan to continue development, looking at processes beyond extrusion and joining technologies for composite parts.

“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.”

In a separate trial, Anybrid was able to demonstrate the potential for ROBIN in combination with a new type of sustainable bio-based material. “We met Dongnam Realize [Daejeon, South Korea] when they won the JEC startup competition at last year’s composites show in Paris,” says Stegelmann. “Their CXP material uses a cellulose-based polymer made from waste wood products.” The Dongnam Realize website notes that cellulose cross-linked polymer (CXP) can be made from sawdust, wood chips, discarded vegetables and even invasive species like certain reeds and water hyacinth, for example.

A raft of polyacetal (POM) resin expansions over the years in China fueled fears of overcapacity in the market but of the nine local players, four have shut down and are unlikely to restart due to environmental, quality and cost issues, while the remainder are operating at rates of less than 50%. Local Chinese players are also primarily serving the lower end of the market comprising fasteners, buckles, coffee machines and the like, and have yet to make any headway into more challenging applications such as automotive.

In 2018, Teijin broke ground on a facility that is reportedly the largest capacity carbon fiber line currently in existence. The line has been fully functional for nearly two years and has plenty of room for expansion.

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.

Chauzu adds, “Due to the great flexibility of the Anybrid technology, the combination with our thermoplastic pultrusion leads to many interesting applications to develop together.”

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

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).

The ITHEC 2024 will take place from the 9 to 10 October 2024 in Bremen, Germany.

The international exhibition will feature 40+ exhibitors showcasing all steps of the supply-chain. Be it materials, machines, testing, processes, or solutions. By combining the exhibition and the conference ITHEC is further fostering the inter-connectivity between science and industry.

Recoat temperature, part orientation and bead geometry are some key design variables to consider for a successful and reliable large-format additive manufacturing (LFAM) process.

Continuous fiber-reinforced thermoplastic composite targets full circularity in aircraft interior applications, with FST, impact resistance and toughness features.

“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.

Consequently, Japanese POM supplier Polyplastics expects the POM market to remain tight for the next three years, and this despite the startup of 50,000 tonnes/year of new POM capacity in Saudi Arabia at Celanese’s joint venture plant with Sabic at the end 0f 2017 and the impending startup of a 70,000-tonnes/year plant in Gimcheon, Korea at a joint venture of BASF and Kolon Plastics; Kolon BASF innoPOM, Inc. This is partly due to shutdowns of capacity by BASF in Germany: 27,000 tonnes/year in 2018 and 28,000 tonnes/year in 2019; in preparation for the startup of the Korean JV.

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.”

Cevotec, a tank manufacturer, Roth Composite Machinery and Cikoni, have undertaken a comprehensive project to explore and demonstrate the impact of dome reinforcements using FPP technology for composite tanks.

CompositesWorld is the source for reliable news and information on what’s happening in fiber-reinforced composites manufacturing. About Us

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.”

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.”
