Introduction to Masterbatch Gross Weighing Machine Manufacturer
A Masterbatch Gross Weighing Machine is a dependable industrial weighing and filling solution engineered for packaging plastic masterbatch granules, additives, and polymer compounds with stable batch control. In a gross weighing system, the bag or container is weighed together with the product during filling, enabling straightforward operation and consistent bag weights for production lines that demand rugged reliability. As a trusted manufacturer, Samirika Group develops gross weighing machines designed for masterbatch handling, including controlled feeding, smooth bag clamping, and dust-managed filling performance. These systems support efficient packaging workflows for color masterbatch, additive concentrates, and polymer granules while helping maintain process discipline and repeatable output.
Working Principle and Process Flow of Masterbatch Gross Weighing Machine
The process begins with masterbatch material feeding from a hopper or silo into the filling spout using a suitable feeder such as gravity, vibratory, belt, or screw feeding depending on granule behavior. The bag is clamped and weighed on load cells, and the controller monitors weight increase in real-time during filling. A fast feed stage typically brings the bag close to the setpoint, followed by a slow feed stage to reach the target weight with improved stability. Once the final weight is achieved, the feeder stops, the bag clamp releases, and the filled bag moves to sealing or stitching. This simple and production-friendly flow makes gross weighing ideal for many masterbatch bagging requirements.
Types of Masterbatch Gross Weighing Machines
- Gravity Gross Weighers – Suitable for free-flowing masterbatch granules with consistent discharge characteristics.
- Vibratory Feed Gross Weighers – Supports controlled flow for mixed-size granules and helps reduce surging during filling.
- Belt Feed Gross Weighers – Designed for steady feeding of polymer granules where gentle handling is preferred.
- Screw Feed Gross Weighers – Useful when additives show bridging or require more forceful and consistent feeding.
- Single-Spout and Multi-Spout Systems – Configured for flexible capacity planning, from single-line to higher throughput packaging.
