Digital doser system for plastics additive feeding

Precisely Feeds Additives in Plastics Processing

The DD Series Digital Doser System, part of the AEC lineup, specializes in precise, variable-speed additive feeding for plastics processing applications, including injection molding, blow molding, and extrusion. Utilizing a variable speed DC drive motor and precision design discs, it ensures accurate, repeatable dosing of pellets or powders. This system supports high-speed, continuous operations and is highly valued for producing plastic bottles, automotive parts, and custom polymer blends.

Enhancing production efficiency, the DD Series offers quick material changeovers with optional spare stations, minimizing downtime and reducing safety risks. It operates within a robust closed-loop control framework, which significantly enhances dosing accuracy. Choose from diverse styles and sizes of dosing discs and hopper capacities to match specific processing needs, including optional dual additives with the DD2 configuration.

Integration into existing systems is seamless, with features such as quick disconnect hoppers allowing off-machine cleaning and 6-inch square mounting flanges for sturdy attachment. The system’s automation capabilities are bolstered by a variable-speed drive and A250 feeder control, while an audible alarm and low-level sensors maintain operational oversight. For extra versatility, the system can be equipped with special voltage options and larger base pieces to accommodate bigger machinery. The equipment is constructed from durable materials suitable for the harsh environments of plastics manufacturing, ensuring long-lasting performance and compliance with rigorous industry standards.
