The principles for mold layout design

1Strive for balance and symmetry
  1.Each mold cavity is concurrently filled under the same temperature condition
   ·Adopt a balanced & symmetric mold layout·

    For an asymmetric layout, balance can be achieved through adjustment of gate dimensions

  2.Runner balance

  3. Symmetric layout for large & small products

    4. Mold force balance, i.e. the center of injection pressure coincides with the center of the main runner, so as to prevent overflow.

2Make the runner as short as possible, to reduce wastage,molding cycle and heat loss. H-shaped layout is better than circular
and symmetric layouts.

3Minimize the number of molding cavities for high-precision products, because product precision will drop by 4% with the addition
of each cavity. Usually, the number of cavities of a precision mold is no more  than four.

4The same color & material

5Compact structure to save steel material

6The larger the closer, the smaller the farther


7Similar height

8First large then small, with the small appropriately fitted

9For the same product, the larger the closer and the smaller the farther

10Good technology capability
