WITTMANN has your solution for Better Blending

Gravimetric blending is central to efficient, profitable plastics processing, yet many molders underutilize their equipment. This issue is compounded by volatile material costs and a shrinking pool of experienced technical staff.

This white paper outlines best practices across four themes: understanding material behavior, mechanical and interface design, system setup, and equipment integration. It examines how virgin resin, colorants, additives, and regrind demand flexible dispensing strategies, and highlights how Real Time Live Scale (RTLS) and adaptive material-learning technologies minimize batch-to-batch variation and costly overdosing.

The paper also addresses mechanical features that support consistency and uptime, along with how blender placement and integration with dryers, granulators, supervisory software, and protocols like OPC UA position the blender as an intelligent hub within a connected work cell.
