volumetric masterbatch doser

volumetric masterbatch doser

volumetric masterbatch doser is a system used to add masterbatch or additives to base plastic materials with precise accuracy. This process is performed using volumetric or gravimetric dosing equipment that ensures high accuracy, uniformity in production, and reduced waste. The use of volumetric masterbatch dosing enables manufacturers to improve product quality and increase the efficiency of plastic production processes by precisely controlling additive ratios. Masterbatch dosing is one of the key stages in plastic manufacturing processes such as injection molding, extrusion, and blow molding. Below, we provide comprehensive information about masterbatch dosing systems.

Types of masterbatch dosing systems Volumetric dosing

In this method, the amount of masterbatch is measured by volume. Volumetric dosing systems are typically suitable for applications with moderate precision and use chrome-plated dosing screws for longer durability.

Gravimetric dosing

In this method, the amount of masterbatch is measured by weight, providing higher precision. Gravimetric dosing systems are suitable for applications requiring high accuracy.

Advanced dosing systems

Advanced, automatic dosing systems with high precision are suitable for producing filler, colorant, and biodegradable masterbatches. These systems utilize modern technologies such as PLCs and remote control and have the capability to dose up to 48 different materials.

Applications of volumetric masterbatch doser

In the plastic injection process for adding additives to base plastic materials, masterbatch dosing is used. This system plays a significant role in improving the quality of products produced in processes such as injection molding, blow molding, and extrusion. It is also highly applicable in the production of products that require high precision, such as engineering, optical, and medical products.

Advantages of using volumetric masterbatch doser

Production of high-precision products

Reduction of incidental costs and waste

Increased production throughput

Compatibility with various steps and processes

Important notes when purchasing a masterbatch dosing system

Based on the type of products you manufacture and your needs, you can choose either volumetric or gravimetric systems. Gravimetric systems offer higher precision and generally come at a higher cost than volumetric systems. When purchasing, pay attention to dosing speed and capacity to ensure they align with your product and line requirements. Also ensure that cleaning is easy and straightforward so you can maintain it well. Finally, confirm that the system is compatible with a wide range of additives and masterbatches.
