Plastic blister card packaging
Blister card packaging is a common and widespread use of plastic packaging products, everywhere in life, they tend to belong
to one-time use items. Because of its recyclability was able to re-create recycled again.
In the remodeling process, the control mold plastic packaging materials from the following aspects: macroscopic examination,
the chemical composition of the steel to ensure the performance is crucial, but qualified components, steel properties can not
be fully explained, due to internal steel inhomogeneity organization and composition of macroscopic examination largely
complements this deficiency.
Crystallization can be observed macroscopically checked steel, steel and destroy the continuity of certain ingredients
unevenness. Standard "structural steel, low times and defect chart" GB1979, common 8 kinds of macro defects: segregation,
porosity, inclusions, shrinkage, bubbles, white spots, cracks, folds.
Assessment Annealing annealing purposes, reducing the hardness of steel, easy machining, but also for the subsequent heat
treatment for tissue preparation. Carbon tool steel annealing organization by GB1298 ratings for assessing the first level.
