Plastic Compounding
Engineered Material Handling for Plastic Compounding
Consistent Batching. Controlled Flow. Reliable Compounding.
Plastic compounding depends on getting the right combination of polymers, additives, fillers and other materials into the process — in the right quantities and with consistent flow.
ISL Technologies provides IBC-based bulk solids handling systems built around patented Cone Valve Technology to help manufacturers improve batching, material flow, containment and process control from ingredient handling through to extruder feeding.
What Are You Looking to Improve?
Better Control at Every Stage of Compounding
Plastic compounding involves multiple materials that need to be accurately measured, handled and introduced into the process.
Accurate Batching
Measure and handle polymers, additives and other ingredients according to defined batch requirements.
Consistent Material Flow
Control how powders and granular materials move from the IBC into downstream equipment.
Reduced Segregation
Maintain a more consistent material stream when handling mixtures containing powders and additives.
Flexible Production
Support different formulations and production requirements through flexible IBC-based processing.
The Challenges Behind Consistent Plastic Compounding
Small Variations Can Affect the Final Compound
The properties of a compounded plastic depend on the materials that go into the formulation and how consistently they are handled.
How Can ISL Technologies Help?
From Batch Preparation to Controlled Extruder Feeding
ISL Technologies combines IBC systems, patented Cone Valve Technology, weighing, dosing, blending and automation to create a controlled material-handling process around your compounding requirements.
Automated Ingredient Handling
IBC systems can be integrated with weighing and batching processes to help gather and measure the required materials for each formulation.
This reduces dependence on manual material handling and helps create a more structured batching process.
Controlled Discharge
The Cone Valve provides a variable and adjustable aperture, allowing the flow of bulk solids from the IBC to be controlled according to the process requirement.
Consistent Material Flow
The Cone Valve's systematic discharge principle is designed to promote controlled material movement and minimize issues associated with conventional discharge methods.
Reduced Segregation
When polymers, additives and fine powders are combined, maintaining material consistency is important. The Cone Valve system is designed to minimize segregation during discharge, helping maintain a more consistent material stream into downstream equipment.
Integrated Process Control
Weighing systems, sensors and control systems can be integrated to manage batching, valve lift and dosing according to the requirements of the application.
The Technology Behind Controlled Material Flow
Patented Cone Valve Technology
At the centre of ISL's IBC systems is the patented Cone Valve.
Instead of simply opening or closing the outlet, the Cone Valve creates a variable aperture that can be adjusted to control material flow.
For plastic compounding, this provides a way to connect IBC storage and batching with controlled discharge into downstream equipment such as extruder feeders.
Variable Flow Control
Adjust the discharge opening according to the process requirement.
Systematic Discharge
Promote controlled movement of bulk solids from the IBC.
Reduced Segregation
Help minimize separation of materials during discharge.
Contained Transfer
Connect the IBC to downstream equipment through a controlled discharge arrangement.
Automation Ready
Integrate valve control, weighing and dosing with automated process systems.
From Ingredients to Extruder
Connect the Compounding Process
A well-designed material handling system can connect multiple stages of the compounding process through the IBC.
Ingredient Loading
Polymers, additives, fillers or other bulk materials are transferred into the IBC.
Identification & Storage
The IBC can function as an identifiable batch vessel for material handling and traceability.
Weighing & Batching
Ingredients can be weighed and combined according to the required formulation.
Blending
Where required, materials can be blended directly inside the IBC using ISL's In-Bin Blending system.
Controlled Discharge
The Cone Valve provides a controlled opening for material discharge.
Extruder Feeding
The material can be transferred into the downstream process, including extruder feeding applications.
Process Control
Sensors, load cells and control systems can be incorporated where automated monitoring and dosing are required.
Applications in Plastic Compounding
Engineered Around Your Formulation
ISL Technologies' IBC and bulk solids handling systems can support applications involving:
Polymer Handling
Controlled storage, handling and discharge of polymer materials used in compounding processes.
Additive Batching
Accurate handling of additives that form part of a specific compound formulation.
Fine Powder Handling
Controlled movement of fine powders where consistent flow and discharge are important.
Carbon Black Handling
Carbon black can present challenging powder-flow characteristics. ISL's controlled discharge approach can help manage material flow and minimize segregation during discharge.
Filler Handling
IBC-based systems can support the storage, batching and controlled discharge of bulk filler materials.
Extruder Feeding
Controlled material discharge can be integrated with downstream extruder feeding systems.
Why ISL Technologies?
Engineering the Material Handling Around Your Process
Plastic compounding is not simply about moving materials from one point to another. The handling system needs to work with the formulation, material characteristics and downstream process.
Proven Cone Valve Technology
ISL's patented Cone Valve technology provides variable control over bulk-solid discharge.
Accurate Batching
IBC systems can be integrated with weighing and dosing systems to support controlled ingredient quantities.
Reduced Material Transfers
In-Bin Blending allows suitable materials to be blended directly inside the IBC, reducing the need for additional transfer stages.
Process Integration
Filling, discharge, dosing, blending, conveying and control systems can be combined into an integrated material-handling solution.
Flexible Manufacturing
IBC-based processing allows manufacturers to manage different batches and formulations within a flexible system.
Automation Ready
Control systems can integrate valve lift, dosing, weighing and process feedback with PLC and SCADA platforms.
Designed for Consistent Compounding
Control the Material Before It Reaches the Extruder
The consistency of the material entering the extruder begins upstream.
An integrated IBC system can connect:
By controlling these stages as part of one material-handling system, manufacturers can reduce unnecessary handling and improve control over how ingredients move through the process.
When Fine Powders Are Part of the Formulation
Control Matters Even More
Fine powders can behave differently from larger granular materials.
Materials such as carbon black may require particular attention to flow and segregation during handling.
ISL's Cone Valve technology provides a variable discharge opening and systematic material flow, helping manufacturers control how the material leaves the IBC and enters the downstream process.
The objective is simple:
Keep the formulation consistent from the batch vessel to the process.
Flexible Production With IBCs
One IBC-Based System. Multiple Formulations.
Plastic compounders often work with different formulations and material combinations.
An IBC-based approach can provide the flexibility to:
This allows the material-handling system to support changing production requirements without being limited to a single formulation.
