What is drag flow?
What is drag flow?
Drag flow is simply half the volume of one turn of the metering section per second at a specific screw rpm, which, when multiplied by a units conversion and the melt specific gravity of the polymer, is a very accurate approximation of the output in lb/hr at no head pressure.
What is the size of RCC slab?
In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.
What is the difference between facility layout and plant layout?

What is switchover position in injection molding?
Solution: The V/P switch-over indicates the point - usually a percentage of the total volume - where the injection molding machine (IMM) will change the filling process from a velocity driven (fill) to a pressure driven control (pack).
What are the differences in toggle and ram clamping?
Toggle clamping is mainly used for high speed injection molding, whereas for precision parts, ram clamping is recommended. Size of the mold and ejector mechanism can also decide in favor of toggle clamping.
What are ejector pin marks?
Ejector pin marks, sometimes called pin push, are the glossy or white imprints caused by the ejector pins that show on the class-A surface of the part. These marks can easily crack during the use of the actual products, so you want to prevent ejector pin marks before they happen.
What is a low volume product?
Low-volume production typically refers to an item that has been produced in small quantities, with little or no engineering, design, or tooling investment. A low-volume production run is often considered to be any order with less than 100 units, although this number can vary depending on the company.

Is 4 mil poly a vapor barrier?
OVERVIEW. Our 4-mil plastic sheeting is a multipurpose film perfect for a wide variety of construction or DIY projects. This medium-duty plastic sheeting is commonly used as a vapor barrier in between insulation and drywall, used as a drop cloth or a temporary cover for equipment and supplies.
Why small batch sizes are important and beneficial?
Small batches go through the system more quickly and with less variability, which fosters faster learning. The reason for the faster speed is obvious. The reduced variability results from the smaller number of items in the batch.
