The realities of a workshop choked with dust and constant handling

Every morning, production managers face the same challenge: ensuring that the hoppers are filled on time to prevent machine downtime—a costly incident that disrupts thermal cycles. Lifting 25-kg bags overhead to fill a feeder located three meters above the ground is ergonomically unsound and poses a major safety risk. Not to mention that these manual operations generate a significant amount of dust, which settles on the molds and compromises the visual quality of the parts produced.

Customers are now looking for solutions that take a back seat to performance. They need equipment that can handle high production rates without breaking a sweat. Pneumatic conveying, while widespread, reaches its limits when electricity consumption skyrockets or when the noise from the turbines makes conversation impossible on the shop floor. Rigid systems, on the other hand, run up against the physical realities of buildings. Navigating around a steel frame or moving from one room to another becomes a headache if the conveyor cannot follow the curves of the architecture.

We need to face reality: an interrupted material flow means thousands of euros in losses. Regardless of the material being processed—whether polypropylene, ABS, or more complex materials like glass-fiber-reinforced polycarbonate—the challenge remains the same. The material must flow smoothly, without separation and without loss of particle size consistency. The issue goes beyond simple mechanics; it affects the very peace of mind of production teams, who would rather focus on fine-tuning settings than on unclogging blocked pipes.

The Precision Mechanics Behind TIM's Flexible Screw Transfer System

To understand the superiority of this technology, we must delve into its very design. Imagine a high-strength steel coil, without a central shaft, rotating inside a tube made of engineering-grade polymer. This coil acts as a true mechanical propeller. Its ability to deform slightly allows it to follow large radii of curvature. This crucial flexibility enables the installation of the flexible screw drive in hard-to-reach corners where no other system could go.

TIM does more than just sell a tube and a coil. The success of such an installation depends on the perfect match between the coil’s profile—whether flat for volatile powders or round for abrasive granules—and the diameter of the tube. The rotation speed is also calibrated to prevent any unnecessary heating of the material. Indeed, certain engineering polymers are extremely sensitive to friction. An improperly adjusted conveyor could begin to soften the pellets even before they reach the press barrel. TIM’s expertise lies in its ability to adjust the parameters so that transport occurs with absolute smoothness.

The absence of internal chambers eliminates any risk of stagnant areas. Manufacturers who frequently change colors know all too well the problem of cross-contamination. Just a few grains of black flux from a previous batch trapped in a corner can ruin an entire production run of transparent parts. The streamlined design of the flexible screw allows for quick cleaning and nearly complete drainage. This saves a tremendous amount of time during production changeovers. Technicians no longer need to disassemble the entire line to ensure the purity of the new flux.

Seamless integration into your machine fleet

Manufacturers of injection molding machines and extruders are designing increasingly compact machines. Floor space is becoming a scarce resource. The flexible screw transfer system addresses this challenge thanks to its lightweight design. The drive motor is typically located at the top, freeing up passageways for forklifts and operators. The distance between the pickup point and the destination can reach several tens of meters, crossing obstacles that would have required massive support structures with conventional rigid screws.

Plastics processors appreciate the system’s ease of operation. The system interfaces seamlessly with the hopper’s level sensors. As soon as the buffer stock decreases, the screw activates to precisely compensate for the machine’s consumption. This consistent feed stabilizes the plasticizing process. Customers seek this stability because it directly affects part weight and dimensional accuracy. A hopper that is always filled to the same level ensures constant pressure at the inlet of the plasticizing screw.

For manufacturers of plastic raw materials, production volumes vary, but reliability requirements are just as high. Filling packaging stations or feeding giant mixers demands uncompromising mechanical robustness. TIM selects steels that have been specifically heat-treated to resist abrasion. Talc powders and mineral fillers, often used in compound formulations, are particularly harsh on equipment. The flexible screw, with its slow yet powerful rotational motion, minimizes premature wear while ensuring a constant flow rate.

Energy savings: a compelling argument for profitability

The issue of electricity consumption has become a key concern in the industry. Pneumatic systems consume an enormous amount of energy to move air, which in turn moves the material. Overall efficiency is often poor. The flexible screw conveyor uses direct mechanical transmission. Virtually all of the energy supplied by the electric motor is used to move the material. Friction losses are minimized by the quality of the internal surfaces of the conveyor tube.

This represents a significant reduction in operating costs over a year of production. When you multiply this savings by the number of machines in a workshop, the return on investment becomes obvious. In addition to the financial benefits, working conditions are also improved. The quiet operation of a flexible screw stands in stark contrast to the constant whistling of venturi tubes or the roar of vacuum pumps. A quieter work environment means operators are less stressed and more attentive to quality.

It is also worth mentioning the environmental aspect. Lower energy consumption and the complete elimination of dust emissions into the factory atmosphere contribute to a cleaner production process. Companies seeking environmental certifications find TIM’s solutions to be a valuable ally. Cleaner floors—free of the pellets that previously escaped from manual systems—also reduce the risk of slips and falls and cut down on cleaning time.

Meeting the Challenge of Recycling and Shredded Materials

The plastics industry is undergoing a revolution with the widespread integration of recycled materials. However, recycled shredded material is unpredictable. Its density varies, its shapes are irregular, and it tends to clump together or form bridges in hoppers. A conventional conveying system often fails to cope with such characteristics. Flexible screw conveyors excel at this task. The rotating spiral acts as a natural de-clogger. It breaks up emerging clumps and forces the material to move forward at a steady pace.

Companies that recycle their own production waste appreciate this capability. The shredder located at the base of the press can be directly connected to a flexible screw conveyor that returns the flakes to the main hopper. The closed-loop system prevents any external contamination and ensures real-time inventory management. This flexibility is essential for manufacturers who must navigate increasingly high recycled content requirements to meet regulatory standards and the expectations of end consumers.

TIM has specialized expertise in managing these heterogeneous mixtures. Knowing that your conveying system won’t jam because of a flake that’s slightly larger than the others provides invaluable peace of mind. Operators no longer have to use mallets on the pipes to get the flow moving again. Mechanics have replaced brute force.

A Human-Centered Approach to a Sustainable Technical Solution

Behind every flexible screw conveyor project lies a real-world situation that TIM takes the time to analyze. A good technician knows that a theoretical solution on paper never survives intact when put to the test on the shop floor. That’s why preliminary analysis is essential. TIM’s engineers visit the site, take measurements, observe existing material flows, and listen to the concerns of those who will be using the equipment on a daily basis. This pragmatic approach ensures that the final installation will be perfectly sized.

Installation does not mark the end of the collaboration. Commissioning is a key moment when fine-tuning is performed. The system must be tested with the most challenging material in the customer’s catalog. If the screw conveyor handles even the lightest shredded material or the stickiest powder without a hitch, then the challenge has been met. Training maintenance teams is also an integral part of the service. Although the flexible screw conveyor requires very little maintenance, knowing how to inspect the spiral for wear or check the tension of the gearmotors ensures that the equipment will last for several decades.

Reassurance also depends on the availability of replacement parts. A punctured tube or a coil that breaks after ten years of loyal service should not bring the plant to a standstill. TIM maintains a stock of critical components so it can respond within a few hours. This geographic and technical proximity is what customers value most. They don’t just want a supplier; they want a partner capable of understanding the urgency of a production line shutdown.

Toward a Comprehensive View of Industrial Performance

Adopting flexible screw conveyors is much more than simply purchasing material-handling equipment; it is a strategic decision that impacts the smooth operation of the entire plant. By freeing workers from tedious tasks, ensuring a reliable supply to machines, and reducing energy costs, the company equips itself to achieve its ambitions. To remain competitive, the French plastics industry must focus on this optimization of material flows, which leaves nothing to chance.

Technology is evolving, and TIM remains at the forefront of these changes. The latest generations of conveyor tubes use polymers that are even stronger and self-lubricating. Motors are becoming smarter, capable of detecting an overload before the mechanical components are even affected. This quest for improvement is not aimed solely at pure performance, but also at the longevity of industrial equipment. A machine that is properly lubricated does indeed last longer.

Investments in the automation of raw material transport are justified by concrete figures: less waste, fewer workplace accidents, and lower electricity consumption. But we must not downplay the intangible aspect either: the pride teams take in working in a clean, modern environment. The company’s brand image in the eyes of its customers changes when they visit a facility where materials move seamlessly, without dust or noise.
