Material handling with reduced noise emissions | #1


How can noise emissions during material handling be reduced? Mo explaines the methods for quiet conveying of plastic granulate.


Material conveying for plastics processing | #2


Which types of material are relevant for plastics processing? Mo explains the procedural principles of bulk material conveying.

Basics of Dosing & Mixing of plastics | #3


mo explaines the basics of Dosing & Mixing for plastics manufacturing and processing.


What are the most important parameters for drying plastics? | #4


mo explains the four parameters for drying plastics. When drying plastics, four interdependant paramaters are key.



How does the dew point impact the drying of plastics? | #5


mo explains the connection between dew-point and (residual) moisture


Why are there different dosing devices? | #6


mo explains: The choice of dosing device depends on the material, the doing principle, and the required throughput



Is there a hard and fast definition of dosing accuracy? | #7


mo explains: “Dosing accuracy” can be defined in many ways, depending on the application.


How do dry air dryers work?| #8


mo explains the principle behind dry air dryers.
Dry air dryers can be categorized as either desiccant dryers or compressed air dryers



What is a permanent central vacuum? | #9


mo explains the characteristics and advantages of a permanent central vacuum for conveying systems.


The “regeneration” process of dry air dryers | #10


mo explains the process of regeneration of drying agents



How does automatic air flow control for dry air dryers work? | #11


mo explains: “When drying plastics, the dry air flow is one of the four main drying parameters and plays an important role.
It needs to be precisely adjusted to the desired material throughput.”


What should be considered when adding regrind to virgin material? | #12


mo explains: “Injection molding produces sprues that can immediately be turned into regrind and reused. This makes sense because it saves money and protects the environment. If the initial material needs to be dried it can save even more money as regrind does not usually need to be dried if it is being reused immediately.”



What is sensor and time conveying? | #13


mo explains: “Conveying systems transport material from storage to where it is needed. If a conveying point signals material requirement, the hopper loader is fed. The signal is usually triggered by a sensor which sends a signal when the material level sinks below a minimum value. But how does the control know how much material is required) The conveyed amount of material can be determined using two different methods.”
