Moldflow develops plastic injection molding software.
STL (stereolithography) is a tessellated representation of the surfaces of a solid, using triangles. STL was initially used in rapid prototyping. STL files can be in either ASCII or binary format. All major CAD/CAM systems can generate an STL file of a solid model.
Industry:Software
Tensile strength is the maximum nominal stress sustained by a material being pulled from both ends, at a specified temperature and at a specified rate of stretching.
Industry:Software
The appearance of this surface defect is similar to the grooves on a record. Record grooves are formed when a high flow resistance exists in the mold, thus leading to a repeated temporary stagnation of the flow fronts.
To prevent this defect, the mold and melt temperatures should be increased while decreasing the injection time.
Industry:Software
The end of fill occurs when the polymer has reached the extremities of the mold cavity and the mold is volumetrically filled.
Industry:Software
The fan gate is the opening between the mold runner and the mold cavity which has the shape of a fan. This shape helps reduce stress concentrations in the gate area by spreading the opening over a wider area.
Industry:Software
The finger gate is used when presentation is important and you want to avoid disfiguring the top face of a part. It tunnels down from the parting plane and comes up on the underside of the part.
This gate is also known by the following names: banana, winkle, cow-horn, bent-tunnel gate and cashew.
Industry:Software
The gate is the channel through which the molten polymer flows from the runner into the cavity. Generally, the gate is small and solidifies first.
Industry:Software
The hopper is the molding machine container that holds the polymer and feeds it to the injection molding screw.
Industry:Software
The injection location is the place where the molten plastic is forced into the mold cavity. Different injection locations can have different effects on the appearance and quality of the part.
Industry:Software
The injection pressure is the pressure that is applied to the ram during the injection phase, causing the material to flow, and can be measured approximately by a transducer located in the nozzle. There is a direct relationship between the injection pressure and the hydraulic line pressure called the machine intensification ratio.
