Robotized systems make overmolding mobile, flexible!
ANYBRID has miniaturized the process to fit within a robot arm end effector, enabling, for example, pultrusions to be overmolded inline or molded structures to be functionalized within a robotic cell. Anybrid has recently completed a series of demonstrations to highlight new capabilities its technology can offer including:
- Overmolding joining/fastening inserts with compression-molded polyamide (PA) composite profiles and polyetherimide (PEI) composite stringers made using continuous compression molding (CCM);
- Combining 3D printing and overmolding;
- Hybridization with new processes and materials such as reactive thermoplastic pultrusion and wood polymer composites.
For automotive applications, demonstrations used Lanxess Bond-Laminates Tepex 102-RG600 PA6 with 47% glass fiber roving for compression molding. Resulting composite profiles were then overmolded using Lanxess’ 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 into a narrow omega-shaped profile.

3D Systems has entered into a commercial agreement with Theradaptive, a biopharmaceutical company innovating in targeted regenerative therapeutics. The agreement names 3D Systems as Theradaptive’s exclusive 3D-printing partner. The companies said they intend to deliver a novel approach to promote bone and tissue growth using Theradaptive’s unique protein-based material-binding variants to coat 3D-printed medical devices.
Theradaptive's protein-engineering technology was developed by Luis M. Alvarez, PhD, after he witnessed extremity injuries that resulted in delayed amputations among service members. His subsequent research into bone and tissue regeneration at MIT focused on addressing the limitations associated with existing regenerative medicine approaches, such as achieving anatomically precise outcomes and ultra-persistent local delivery of therapeutics. The first applications of this technology have already earned three Breakthrough Medical Device designations from the FDA to address degenerative disc disease and spinal fusion.
3D Systems has worked with surgeons for more than a decade planning more than 150,000 patient-specific cases, and additively manufacturing more than two million implants and instruments for CE-marked and FDA-cleared devices. The Rock Hill, SC–based company has also made significant strides in regenerative medicine, most recently announcing its Regenerative Tissue Program.
“This agreement enables an exciting technological convergence of 3D Systems’ cutting-edge advances in orthopedic and soft tissue additive manufacturing and Theradaptive’s material-binding regenerative therapeutics,” said Alvarez, CEO and founder of Theradaptive. “Uniting these two world-class technologies promises to provide safer and more effective treatment options for patients who currently have few options. This partnership sets the stage for many new products that will have the potential to significantly improve patient care,” said Alvarez.
In addition to being named as Theradaptive’s exclusive 3D-printing partner, 3D Systems also made an $8 million investment in the company.

China’s major carbon fibre and composite materials producer Hengshen announced that the supporting cabin of the main load-bearing part of a civil rocket that the company developed, designed and manufactured, passed the static test assessment in Shanghai. After a 20-day load test, it finally ended with the ultimate bearing capacity exceeding the design load by more than 120%.
The rocket support cabin is the key main load-bearing component of the launch vehicle to carry the satellite. It is located between the last stage power cabin of the rocket and the satellite, and is an important load-bearing and connecting structure in the rocket structure.
Hengshen indicates that the support module will be used to carry the Zhuque-2 launch vehicle, with a total weight of more than 200 tons. In order to achieve the goal of weight reduction under complex load conditions for satellite launches, the support cabin adopts a carbon fibre composite material foam sandwich structure design scheme, and uses the EM817B resin system prepreg independently developed by Hengshen. By optimizing the structural design, the difficulty in the molding process of the foam sandwich structure in the load concentration area has been overcome. Compared with the original metal support cabin, the weight has been reduced by 42.3%, and the ultimate carrying capacity has been improved by more than 50%.It has great potential for commercial application in the development of civil launch vehicles, says Hengshen.
The Hengshen support cabin project was launched in the Advanced Manufacturing Division in April 2022, and the first delivery was completed in April 2023. After the start of the project, the business department organized a cross-departmental and cross-professional project research team to achieve cooperation of professional technicians and operators in structure, strength, process, mold, assembly and quality. This enabled the first part of the project to be delivered on schedule.
According to the project manager, the rocket support module is the first delivery of Hengshen’s composite material parts segment in the commercial aerospace field, marking a major breakthrough in Hengshen’s commercial aerospace composite manufacturing capacity. At the same time, it also marks that Hengshen has taken a solid step in commercial aerospace composite parts and components manufacturing.

Why would you choose a larger gate when molding amorphous polymers ?
This is often mentioned and linked to the typically higher viscosity of amorphous polymers that do not undergo the sharp melting transition with associated dramatic drop of viscosity.
But one major aspect to consider is packing. Due to the already mentioned pressure effect on viscosity and no-flow temperature for this class of polymers a larger gate, with its longer freeze-off time, will allow you to pack for longer, and thus use a lower packing pressure, avoiding the aforementioned pressure dependent problems altogether.
Keep in mind that a longer freeze-off time creates a higher risk of differential shrinkage (gate area overpack), to be addressed with the proper packing pressure profiling.

The REFORM project aims to develop metal-free electronic components from bio-derived adhesives, conductive inks and flexible substrates to help reduce the dependency on finite resources such as scarce metals and unsustainable materials.
AIMPLAS, the Plastics Technology Centre, participates in this EU funded project, led by CIDETEC, that focuses on the development of printed green electronics that will accelerate and guide the creation of a new European functional electronics supply chain.
Reduction in E-waste:
Although each electronic device contains very limited amounts of critical materials, they are produced on a vast scale, meaning that the cumulative environmental impact of e-waste is substantial, particularly if components are embedded in ways that make recycling extremely difficult or uneconomic.
The devices that aren’t recycled or disposed of correctly can often be found in landfill sites, where all sorts of dangerous toxins and carcinogenic substances, such as mercury, lead and cadmium, leach into the surrounding soil.
The REFORM project seeks to develop environmentally sustainable printed electronics by harnessing organic conductive inks and biodegradable or recyclable materials.
Specifically, the project will develop three prototypes, a green smart logistics tag, a green embedded wireless sensor and a micro supercapacitor.
REFORM will employ eco-design principles to produce green printable electronics that meet the demands of multiple industries and sectors so that e-waste ceases to be a problem in the future.
Contribution to Recyclability:
AIMPLAS will contribute its experience in the recyclability of the materials and products developed in the project. More concretely, AIMPLAS will develop a pathway to achieve an effective sorting of printed electronics and a new innovative method for the recovery of metals that contain these products.
After the sorting and metal recovery, AIMPLAS will test which recycling method is better for the printed electronics recycling, including chemical and mechanical recycling tests.
REFORM is a 42-month project and has received funding from the European Union's Horizon Europe research and innovation program under grant agreement No 101070255.
