12 Questions
What is the main purpose of blending in the plastic processing industry?
To combine material ingredients in predetermined proportions and mix them for plastic part production
Why did some processors opt for blending instead of purchasing pre-compounded materials in the past?
Pre-compounded materials were more expensive
How did cost-conscious processors manage the regrind produced from their processes?
By rolling it back into their own process if possible
What characteristic of custom compounds made them costlier compared to individual raw ingredients?
Their specialized properties and colors
Why was it important for processors to effectively deal with the regrind from their processes?
To minimize material wastage and costs
What was the primary reason for processors to introduce regrind back into the material stream?
To maintain a consistent material supply
What is the purpose of blending and dosing devices in the manufacturing process?
To ensure a continuous and efficient flow of materials
How do dosing devices operate in injection molding processes?
They introduce additives continuously into the material flow
What role does a mixer play when connected below a dosing device?
It enhances the blending of additives with base resins
Why is dosing provided at a certain rate in extrusion processes?
To match the speed of the extruder
For what purpose might multiple dosing devices be connected to a single machine throat?
To allow rapid changeover ease with redundant dosing units
What is a critical aspect regarding the mounting frame for dosing devices connected to a machine throat?
The frame ensures coordinated operation with extruders or molding machines
