INJECTION STRETCH BLOW MOLDING METHOD FOR HOLLOW BODY WITH THICK BOTTOM WALLPURPOSE: To provide the method of biaxial stretch blow molding a hollow body with a thick bottom wall by using a preform of simple shape.YOKOBAYASHI KAZUYUKI横林 和幸...
members is so provided as to be linearly reciprocated between a position where it retracts outward from the bottom face member and a position where it closely abuts against the bottom face member and the other peripheral wall members adjacent thereto to form an original form of the female mold....
You'll want to make sure the bottom of the crown is flush against the saw guard at the bottom and the top of the crown is leaning against the jig: Make sure your jig is out of the way of the saw blade, then cut in the direction for your inside or outside cut. Most corners ...
CONSTITUTION:When the portion, at which operating liquid 43 stands, of a bottom wall 33 is heated by induction or by direct contact with a fire, the operating liquid 43 evaporates by absorbing the heat as latent heat. The evaporated portion of the operating liquid fills a hollow layer 31 ...
The baseline used in the calculation was the center line of the arithmetic average, i.e., the line when the top and bottom areas of the contour were equal. It should be noted that the surface roughness of the molded PEEK samples was greater than the surface roughness of the mold (Ra≈...
where L and W represent the large and the small diameter of the ellipse, respectively. To calculate the area of the defect, a direct measurement of the value of W, the value of L was calculated by measuring the length of the arc from top edge to bottom edge of the defect, as shown ...
Side-action cores are moving elements that enter the mold from the top or the bottom and are used to manufacture parts with overhangs (for example, a cavity or a hole). Side-actions should be used sparingly though, as the cost increases rapidly. Interesting fact: About 50% of the typical...
a thick wall part and a thin wall part to be obtained stably by providing in a core a slurry injection path having an outer opening and a plurality of inner openings made into a casting space, and injecting at least a part of the slurry into the casing mold through the injection path....
PROBLEM TO BE SOLVED: To provide a method and a mold for blow molding which prevent a sink mark in the vicinity of a compression part and also make it possible to form the wall thickness of a resin to be prescribed substantially and thereby to keep the strength thereof.;SOLUTION: A mold...
and the final part shape and wall thickness that is an experiential learned relationship. This hanging vertical parison is extruded down and in between a mold which clamps up over the parison, pinching it off at the bottom and at the top. A blow pin is inserted through the parison to allow...
