Casting film is a non-stretchable, non-oriented and flat extruded film produced by rapid cooling of melt casting, with superior heat-sealing performance and excellent transparency. The stability of product quality cannot be achieved without precise material ratios, among which the selection, matching, dosage, and mixing of formulas are key elements in the composition and design of casting film formulas, which will affect the quality of casting film products.
Mconvey understands what you think and matches your needs. We provide a full range of mixers that can adapt to different material ratios and mixing aspects. In this issue, we will delve deeper into the weighing, dosing, and mixing solution of Mconvey’s multi-component materials – the Gravimetric blender – through the application of Mconvey’s Gravimetric blender on the casting film production line.
A domestic customer operates nine three-layer co-extrusion casting film machines. While these machines use a single formula, they involve multiple raw materials. The raw materials are conveyed to the extruder head through a raw material distribution station. Previously, the customer relied on manual operations for dosing, weighing, and mixing. This approach led to low work efficiency, frequent human errors, raw material waste, and dust overflow—seriously affecting product quality.
Based on the customer’s actual production needs, Mconvey provided a comprehensive front-end material handling system. The solution covers material storage, weighing, mixing, and feeding, and includes:
- Feeding buckets
- Storage silos
- Material distribution stations
- Gravimetric blenders
- Feeding fans and filtration components
- PLC control systems
Through this upgrade, Mconvey helped the customer achieve fully automated material supply operations. The transformation improved on-site management, effectively saved space, and reduced labor costs. In addition, it minimized raw material loss and dust pollution, while further enhancing product quality and production efficiency.
Mconvey Gravimetric Blender: High-Precision Automatic Dosing for Casting Film Production
The Mconvey Gravimetric blender plays a crucial role in casting film production, where precise raw material ratios are essential. As a high-precision automatic dosing and mixing machine, it is designed to handle various plastic particles, masterbatches, and auxiliary agents simultaneously.
This Gravimetric blender is ideal for applications that require strict weight-based dosing and mixing. By automating the process, it significantly reduces manual mixing procedures and minimizes the risk of human error. As a result, it effectively improves production accuracy, enhances automation levels, and ensures consistent product quality.
Mconvey Gravimetric Blender features:
- PLC fully automatic control: touch screen display, easy to understand and user-friendly.
- Modular assembly structure: Each component can be quickly disassembled and easily cleaned and can be installed on the main machine or ground for use.
- Stable performance: All key weighing and feeding valves are precision cast to ensure stable performance.
- High feeding accuracy: The pneumatic “plug valve” acts quickly about 4-5 times/second.
- Flexible formula: It can quickly switch formulas online, eliminating the hassle of professional calibration, and has powerful formula storage function.
- Uniform mixing: A unique 45 degree mixing device ensures uniform mixing without dead corners.
- Accurate metering: All materials are evenly mixed through gravity metering, and the precision of micro metering can be strictly controlled at 0.5%.
- Network interconnection and interworking: Equipped with network ports, it can achieve centralized monitoring and networking with molding machines.
