PE plastic suction nozzle
PE material
Crystallized material, little moisture absorption, no need to enrich boring, fluidity depends on fluidity is sensitive to pressure, molding time with low pressure injection, material temperature average, filling rate fast, keep pressure filling.There is no appropriate indirect gate, in order to prevent expansion without even, internal stress increase.Careful selection of gate location to avoid inoculating shrinkage cavity and deformation.
The expansion category and the expansion value are big, the direction is more, difficult to deform warping.The cooling rate should be slow. The mold should be equipped with a cold material hole and a cooling system.
Add cold time to do not have appropriate too long, otherwise can produce synthesis.
Soft plastic parts have shallow side grooves, do not force out.
Whether can produce melt body break, there is no suitable organic solvent to fight, in order to prevent cracking.
PE plastic suction nozzle,Widely used in the food industry.For example, jelly, milk, soy milk, ketchup and other food self-reliance bags.
