Volumetric - Gravimetric Raw Material Dosing Devices

Nowadays, while plastic use is increasing rapidly, plastic production is also increasing in our country. Plastic parts are widely used in many important sectors such as automotive, white goods, textile, food, medical, construction, aviation, space and packaging. However, one of the biggest problems in this growing sector is the high prices of raw materials and additives, which affects manufacturers and end users. The method of adding masterbatch (MB) and additives used in plastic production to the raw material is an important factor in determining the production cost. In particular, the dosing systems used for MB, which is widely used in all plastic processes, help to minimize raw material and additive costs. Dosing systems are generally classified as gravimetric and volumetric: Volumetric Dosing: It is a form of dosing made with units such as screws and discs that are calibrated with certain assumptions according to the density and flow values ​​of raw materials and additives, are driven by a motor and have the appropriate pitch range. Gravimetric Dosing: Thanks to its weighing capability, it is a system that can dosing on a weight basis as a result of calibration made in accordance with the density and flow of raw materials and additives.
