Production Cost Of Stool Mould

  • The plastic Stool Mould design requires a rounded edge at the end of the side wall. Therefore, the parting line must be moved to the position where the radius intersects the outer wall formed by the cavity. There is usually no particular reason to oppose this design, except that it is more expensive to produce. For very light products, especially when ejecting with a stripper, the radius of the stripper may cause the product to hang and not leave the mold. Then special mold features, such as air blows or wipers, may be required to ensure that all parts have been ejected. Generally, heavier molded parts (approximately 20 grams or more) are no problem.

    The main problem with having rounded edges at the end of the wall is that there may be a mismatch between the cavity and the core, which may result in smaller but sharp corners (ridges). An example is the rim of a drinking cup. When drinking from such a cup, the ridges on the lips can be annoying.

    Regardless of the plastic stool of the parting line, similar methods are used to avoid any parting line mismatch: round, oval, rectangular, irregular or eccentric. The more difficult challenge is to foresee where the mismatch may occur and determine how to determine the size of the product.
