Two important results arise from the use of linear elements: 1) weld lines will always be seen on the edge of an element, and 2) air traps
must surround a single node.
Jada Plastic engineers use Moldflow software to evaluate and determine gate locations to make sure weld lines will not appear in critical part areas, to eliminate the possibilities of air traps
, and to establish accurate pressure fill with regard to gate locations.
This 'preventative analysis' detects a wide range of potential manufacturing issues such as warpage, weld lines, air traps
, filling issues and hot spots, while determining the optimum gating position.
Moreover, the produced panels will e aesthetically excellent and ompletely free of air traps
, he added.
Filling a long-unmet need for viable programs to simulate gas flows in thick tubular products, CGI says, the new 3D flow analysis programs enable accurate predictions of material weights and time cycles; more precise simulation of wall thicknesses for assessing product strengths and weaknesses; optimization of materials, plastic feed, and gas injection positions; study of variations related to gas timing; and prediction of blowout situations, weld lines, and air traps
The Willamette Valley is caught in a weather inversion, where warm, dry air traps
the cool air below it in a stagnant pocket.
can be effectively controlled using insert line venting if the same care is taken to keep the blast media and die coating free of the clearance gap.
You may need to change the gate location to avoid race-tracking or air traps
All air with its potential contaminants is evacuated from the box to remove any air traps
in the mold.
Users can overlay more than one result at a time on the same model, such as fill time and air traps
, weld lines, or core/skin orientation.
