Bosch manufactures one of its drills using only recycled technical plastics:

Reinforced plastics, or composite materials, are always more difficult to recycle than other materials such as metals. Nevertheless, Bosch decided to try to reduce the carbon footprint of its power tools, which are largely made from engineering plastics. In this context, the company launched a pilot project to produce a special edition of its UniversalImpact 800 hammer drill, whose casing – all visible external components of the main product, except for cables and accessories – would be made with the highest possible proportion of recycled engineering plastics from old appliances, without compromising appearance, feel and quality.

It was clear that products made from recycled materials had to retain the characteristics of those made from virgin materials, i.e. their ability to withstand both variable thermal stresses and impact loads during drop tests. In addition, Bosch wanted the recycled material to be able to be integrated into regular production lines without any adjustments. “The challenge was to achieve a series production quality for our special edition based on old devices – this was completely new territory, without established standards or years of practical experience,” explains Thomas Hampel, Sustainability Expert at Bosch Power Tools.

A pioneering project for the circularity of engineering plastics

Before producing the Closed-Loop edition of its UniversalImpact 800 hammer drill, Bosch conducted a feasibility study in which thousands of discarded power tools were collected, dismantled and analysed. Subsequently, only technically suitable and legally approved plastics were used to manufacture the recycled edition of the UniversalImpact 800. The Bosch team was able to use the recovered material directly, without adding any additives or additional glass fibres, and the final material met all the usual quality requirements.

The success of this pioneering project has become a model for other circular economy initiatives. Bosch’s closed loop has been certified by TÜV Süd. Bosch’s UniversalImpact 800 Closed-Loop Edition contains 78% recycled materials, but this does not mean that recycled engineering plastic cannot be used on its own. The remaining 22% consists of components such as switches, mandrels and soft handles, which are made from other types of plastic or different colours.

With this project, we are demonstrating that we can indeed circulate technical plastic. The project targets several key areas of our sustainability strategy: responsible material use, circularity and CO₂ reduction,” explains Anne Purper, Circular Economy Project Manager at Bosch Power Tools.

The process appears to run correctly through all its stages: crystallization and pre-drying, extrusion, pelletizing and post-crystallization.

The pellets coming out of the centrifuge are white and glossy, have a homogeneous IV value and are ready for the final step of IV-boosting and decontamination (super-clean).

They are then reheated and fed into the Solid State Polycondensation (SSP) tower - under nitrogen atmosphere or under vacuum with nitrogen flow.

🟥 But here a problem arises: 𝘁𝗵𝗲 𝗽𝗲𝗹𝗹𝗲𝘁𝘀 𝗲𝘅𝗶𝘁𝗶𝗻𝗴 𝘁𝗵𝗲 𝗿𝗲𝗮𝗰𝘁𝗼𝗿 𝗮𝗿𝗲 𝘃𝗶𝘀𝗶𝗯𝗹𝘆 𝘆𝗲𝗹𝗹𝗼𝘄𝗲𝗱.

The heat required for the polycondensation reaction has triggered a 𝘁𝗵𝗲𝗿𝗺𝗮𝗹 𝗱𝗲𝗴𝗿𝗮𝗱𝗮𝘁𝗶𝗼𝗻 that did not appear in the previous stages.

Pellets that were formally suitable up to that point suddenly become 𝗻𝗼𝗻-𝗰𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝘁 𝗳𝗼𝗿 𝗳𝗼𝗼𝗱-𝗰𝗼𝗻𝘁𝗮𝗰𝘁 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀: they may be downgraded and sold for alternative uses (e.g., strapping) or reprocessed, but they can no longer be used in food-grade applications.

The result is the 𝗹𝗼𝘀𝘀 𝗼𝗳 𝘁𝗼𝗻𝘀 𝗼𝗳 𝗺𝗮𝘁𝗲𝗿𝗶𝗮𝗹, 𝘄𝗮𝘀𝘁𝗲𝗱 𝗸𝗪𝗵 𝗼𝗳 𝗲𝗻𝗲𝗿𝗴𝘆, 𝗻𝗶𝘁𝗿𝗼𝗴𝗲𝗻 𝗮𝗻𝗱 𝗼𝘁𝗵𝗲𝗿 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗰𝗼𝘀𝘁𝘀 - all inevitably thrown away.

At that stage, the only corrective action is to over-dose the melt with anti-yellow additives - even when, in reality, they would not be needed.

🟩 The 𝘀𝘁𝗿𝗮𝘁𝗲𝗴𝗶𝗰 𝗰𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻 of the 𝗶𝗤𝗼𝗻𝗶𝗰𝗧𝘄𝗶𝗻 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 stands in sharp contrast to competing mechanical-recycling systems, because 𝘁𝗵𝗲 𝗦𝗼𝗹𝗶𝗱 𝗦𝘁𝗮𝘁𝗲 𝗣𝗼𝗹𝘆𝗰𝗼𝗻𝗱𝗲𝗻𝘀𝗮𝘁𝗶𝗼𝗻 (𝗦𝗦𝗣) 𝘀𝘁𝗮𝗴𝗲 𝗶𝘀 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗲𝗱 𝗯𝗲𝗳𝗼𝗿𝗲 𝗲𝘅𝘁𝗿𝘂𝘀𝗶𝗼𝗻.

This approach delivers at least three decisive advantages:

✅ Color correction can be applied to the pellets only when needed and in the exact required amount.

✅ Pellets with non-conforming color are identified 𝘣𝘦𝘧𝘰𝘳𝘦 entering the so-called “food” storage area and can therefore be immediately diverted to the “non-food” zone, preventing contamination.

✅ Production can be stopped instantly if the incoming material shows abnormal levels of non-conformity, avoiding tons of already-extruded waste.

📌𝗖𝗼𝗹𝗼𝗿 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝗮𝗻𝗱 𝘄𝗮𝘀𝘁𝗲 𝗽𝗿𝗲𝘃𝗲𝗻𝘁𝗶𝗼𝗻 are only some of the benefits enabled by the strategic configuration of the 𝗶𝗤𝗼𝗻𝗶𝗰𝗧𝘄𝗶𝗻 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 by MAS Austria.

Today's KNOWLEDGE Share : The Reynolds number

Today's KNOWLEDGE Share

The Reynolds number is one of the most important, yet often misunderstood or overlooked, metrics for injection molding. This critical value predicts fluid flow patterns in cooling systems, determining whether coolant flow is laminar or turbulent. At a Reynolds number below 4,000, coolant flows in smooth layers with minimal mixing, leading to poor heat transfer and unstable mold temperatures. Above 4,000, the transition to turbulent flow enhances cooling efficiency, with an ideal range between 4,000 and 8,000.

Inefficient cooling can cause a host of issues, from long cycle times and deformed parts to weld lines, poor surface finish, and incorrect dimensions. Scale buildup as minimal as 0.020 inch can act like adding 2 inches of steel between coolant and polymer, severely degrading thermal transfer. Fortunately, solutions like descaling systems and thermal mapping can address these challenges and improve overall equipment effectiveness (OEE).

Coolant temperature control inside the mold is critical to performance and quality, making an effective Reynolds number essential for efficient thermal transfer. How do you monitor and maintain cooling efficiency in your injection molding processes? What challenges have you faced with mold temperature control?

Today's KNOWLEDGE Share : Eliminating Gels in Plastic Film Production

Today's KNOWLEDGE Share

Eliminating Gels in Plastic Film Production:

Gels and fish eyes are among the most common defects in plastic film extrusion tiny impurities or agglomerates that compromise optical clarity, surface smoothness, and mechanical strength.

Main causes include:

Contaminated or poorly filtered material

Discontinuous filtration

Unstable temperature or pressure during extrusion

👉 The answer lies in continuous filtration, maintaining constant pressure and removing impurities without stopping production.

One of the most remarkable features of our AP series (https://lnkd.in/dJrHhs66) is its ability to remove gels and fish eyes during film production.

This is possible thanks to:

🔹 Cylindrical filters with a particularly large filtration area

🔹 The use of metal non-woven mesh, with filtration capacity from 3 to 100 µm

🔹 Exceptionally effective removal of micro-defects

With traditional flat filters, these meshes cannot be used — back pressure would simply be too high.

✅ Fewer impurities

✅ Cleaner, more homogeneous films

✅ More stable and efficient extrusion

Efficient filtration means superior product quality.

Arkema announces a proposed divestment in plastic additives

Arkema announces the proposed divestment to the Indian group Praana of some of its businesses in impact modifiers and processing aids, additives used in the manufacture of #PVCprofiles, pipes and packaging as well as engineering plastics. With this project, the Group continues to refocus its portfolio on its strategic activities.

This proposed divestment concerns Arkema's impact modifiers and processing aids businesses, and covers the global scope for Methyl Methacrylate Butadiene Styrene (#MBS) copolymers as well as the European and Asian scope for acrylic copolymers (AIMPA).

These activities, part of the Coating Solutions segment, generated €44 million sales in 2024.

This project entails the divestment of the Vlissingen production facility in the Netherlands which employs 50 people. On the other hand, #Arkema will keep within its scope the Mobile plant (United States) as well as all the entirety of its American AIMPA businesses.

These plastic additives enable notably to enhance impact resistance and optimize the productivity of extrusion and molding processes for PVC and for a number of composites used in the construction and packaging sectors.

The Indian group #Praana is a leading producer of specialty chemicals and composite materials comprising #SterlingSpecialtyChemicals, #GalataChemicals, Artek Surfin Chemicals, and #3BFibreglass, which offer advanced solutions for the construction, textile, automotive, cleaning and personal care products industries as well as various industrial markets.

This proposed divestment is expected to be finalized in the first quarter of 2026 and is subject to a preliminary information and consultation process involving the employee representative bodies in the Netherlands.

Arkema thus continues to actively manage its portfolio and to refocus on strategic and higher value-added activities in Specialty Materials.
