Quality Policy Statement

It is the policy of The Bonnot Company to provide our customers with products which are continually improving to meet or exceed their requirements in a timely manner.

We are also committed to complying with applicable requirements and improving the effectiveness of QMS. The responsibility to achieve these objectives is shared by all of our employees.

How does The Bonnot Company approach Extruder design?

Define Requirements:
Understand the material(s) to be processed. Define the required throughput and processing temperature. Consider the desired output shape and size.
Select Extruder Type:
Choose from our exisiting library of single-screw extruder designs.
Conduct Testing to Verify Mechanical Design:
Determine the screw geometry, including length, diameter, and pitch. Design the barrel, considering material compatibility and thermal requirements. Ensure proper heating and cooling mechanisms to control the temperature of the material during processing. Select a motor and gearbox based on the required torque and speed.
Material Handling:
Implement a feeding system that suits the material properties. Consider whether the material requires pre-processing or conditioning before entering the extruder.
Die Design:
Design the die or nozzle to achieve the desired shape and size of the extruded product. Consider the die swell and drawdown characteristics of the material.
Safety Features:
Implement safety features such as emergency stops, interlocks, and temperature sensors to prevent overheating.
Instrumentation and Control:
Install sensors and instrumentation to monitor temperature, pressure, and other relevant parameters. Implement a control system to regulate the extrusion process and ensure consistency.
Testing and Optimization:
Conduct trials with different materials and operating conditions to optimize the extruder’s performance. Fine-tune the design based on actual performance data.
Documentation:
Document the extruder design, including drawings, specifications, and operating procedures. Specific requirements and considerations may vary depending on the application and the material being processed. It’s essential to collaborate with Bonnot experts in materials science, mechanical engineering, and process engineering during the design process. Additionally, prototyping and testing are crucial to validate the design and make necessary adjustments.
