plastic thin wall parts customized
Most?injection mold company?usually apply the lifter structure as shown. The lifter employs the 8407 steel with a hardness of up to HRC50-52. There should be a distance of 1 – 3mm from the angle lifer to the product, with a clearance of 0.1mm on each side of the base made of the 738 steel, while the length tolerance is +1.5mm and +1.0mm on the top and bottom respectively.
At the end close to the melt flow, a 5.0mm plane surface has to be made (unnecessary when the part profile surface is plane), as well as a head that is bigger than (if not equivalent to) 1.0mm, to prevent the angle lifter from being moved by pressure during the?injection molding process. A C0.2 chamfer needs to be set up on the mold core at the corner of the head.
