What is an elastic layout?
A mixform between the fixed and the fluid layout is the elastic layout. The element-widths are expressed in em, which depends on the font size. Therefore the layout does not change when the Window size changes, but rather when the font size changes.
What is runner in mould?
A runner is a channel cut into the mold that allows plastic material to flow from the nozzle to the cavity. A change in pressure is expected whenever the viscosity changes or the flow channel thickness (or diameter) changes. Pressure will increase when you have a reduced thickness.
What is production volume?
Production volume variance is a statistic used by businesses to measure the cost of production of goods against the expectations reflected in the budget. It compares the actual overhead costs per unit that were achieved to the expected or budgeted cost per item.
What is the minimum precision that can be expected of an injection molded components?
Typically, injection molding will produce parts with tolerances of ± 0.500 mm (0.020”). Tighter tolerances down to ± 0.125 mm (0.005”) are also feasible in certain circumstances. This level of accuracy is enough for most applications and comparable to both CNC machining and 3D printing.
What is PVC moulding?
Polyvinylchloride or PVC trim is a material that can be used in place of wood for many building and construction projects. Cellular PVC can be molded and shaped just like wood and is rapidly becoming a favorite option for builders and contractors for trim work around new homes and other such projects.
Why is l’d important?
As discussed on the maximum flight time page, low fuel usage allows an aircraft to stay aloft for a long time, and that means the aircraft can fly long range missions. So an aircraft with a high L/D ratio can carry a large payload, for a long time, over a long distance.
What is the difference between LDPE and PP?
The term PP stands for polypropylene while the term LDPE stands for low density polyethylene. These are polymer materials that fall under the category of plastics. The key difference between PP and LDPE is that PP is a crystal-clear material, whereas LDPE is either translucent or opaque.
What is the minimum width of wall in load bearing structure in MM?
Thickness Requirements for Load Bearing Masonry WallThe thickness of load bearing masonry wall should be at least 304.8 mm (1 ft.)
How much infill do I really need?
As you can see the proper amount of infill is completely dependent on your application. For most residential landscape applications, the safe bet is between 2.5 and 3.0 lbs. of 12/20 or 16/30 Envirofill per square foot.
What is extrusion pressure flow?
The polymer is forced into the mold using pressure flow. Drag flow is induced by a surface dragging over a fluid. This is similar to a boat causing water to flow as it travels. In the extrusion industry, the screw rotating causes the polymer to flow by dragging the polymer along the barrel.
