TIM Volumetric Dosing and Weighing Solutions for the Plastics Industry
In the plastics industry, the final quality of a product depends on the precise proportions of raw materials, processing aids, and mineral additives. At TIM, we design equipment capable of ensuring this consistency through a comprehensive line that combines volumetric feeders and gravimetric weighing systems. Suitable for pellets, virgin powders, or recycled powders, these technologies ensure a smooth feed to production lines while optimizing yield and manufacturing consistency.

Volumetric Feeder and Continuous Feeding for Plastics
We have developed several models of volumetric dosing systems designed for single-product or multi-product dosing, with an accuracy of plus or minus 2% depending on the configuration selected.
Each station can process different types of materials: polymer pellets, engineering plastics, or regrind from recycling. Feed rates are adjusted according to production needs to ensure a continuous supply to the injection molding machines and extruders.
Once the quantity has been determined, the materials pass through a flexible Transitube mechanical feeder, which ensures smooth transfer and mixing into the machine’s hopper. This process preserves the integrity of the products, prevents clogging, and adapts to all installation constraints, whether related to height, angle, or distance from the floor.
For manufacturers seeking precise control over proportions and continuous operation, the volumetric dosing unit TIM is a reliable choice, as it is capable of maintaining high production rates while minimizing material loss.
Volumetric Dosing Devices and Gravimetric Weighing Systems
In addition, we offer gravimetric weighing solutions capable of handling up to nine different products with an accuracy of up to one gram per batch. Each screw feeder is controlled by a control unit that adjusts the dispensing according to the defined program. The dispensed materials are then mixed in a hopper equipped with a mixing system, which ensures uniform distribution of the components throughout the mixture.
This equipment covers several configurations: PLC-controlled single-product dosing, batch filling from a silo, cumulative dosing of multiple batches up to a given threshold, or ATEX-certified systems for hazardous areas. Applications include the dosing of additives—such as calcium carbonate, titanium dioxide, lubricants, and stabilizers—which are essential for the production of plastic tubes and profiles.
Each project follows a rigorous process, from the design phase in the engineering department to on-site commissioning, including preliminary testing on samples to calibrate the motor, flow rates, and timing. Our support also includes operator training, preventive maintenance, and a responsive spare parts service, ensuring the long-term reliability of the equipment.
With more than sixty years of expertise, we have established ourselves as a trusted partner for any company seeking to optimize its plastic processing operations. Whether it involves integrating a high-performance volumetric feeder or a complete gravimetric system, each solution is designed to meet production requirements, improve mix consistency, and reduce costs associated with downtime or material loss.GDRHSDFH
