Family mold is mold with multiple cavity and making different plastic products in one mold. Family mold case be used formold, silicone compression molding and injection molding etc.
What is the advantage to make family mold?
It is very useful to save mold cost if the procreative parts quantities is not many pieces as you can put different parts in one mold and do not need to make seperated mold . Normally if the plastic parts quantities is more than 300,000 pcs, you do not need to consider the family mold completely as my point of view.
What is the disadvantage to make family mold?
On family mold, it is diffcult to control thebalance compare to the single cavity mold and multiple cavity mold. Normally SEASKYTOOLING use mold flow analysis to design the runner and for family mold, also there should be some of fine tune after the first trial. During the first mold trial, the short shot samples have to be trialed for the gate and runner fine tune to balance the runner system.
For plastic injection family mold advantage and disadvantage
As above said, there is runner balance issue, this should be spent a little bit more labor or analysis.
Also on the family mold, you can choose different color plastic parts in one family mold, you can not do the production in one time as it is just possible to shot one color in one time, then the other cavity will be disengaged, production capacity is wasted.
On family mold, you can also choose different plastic parts with different resin in one family mold, but you can not do the production for all of the cavity in one time due to the resin is different, then the other cavity will be disengaged, production capacity is wasted.
Both above is the advantage and disadvantage, advantage is to save the cost for more injection molds to do the production, the disadvantage is that there is production capacity loose. These should be considered the disadvantage and advantage based on your demand for the plastic parts andstructure. SEASKYTOOLING can be your partner to consider this cost analysis together with you to save cost for your plastic product development.
Rubber compression family mold advantage and disadvantage.
For the rubber compression family mold, there is no disadvantage on the runner balance thanks to that there is no runner on the rubber compression mold.
For the different color rubber cavity different shore rubber cavity and different rubber cavity, the disadvantage and advantage is the same as injection molding family mold.
Die casting family mold advantage and disadvantage.
Die casting mold normally did not have different color during die casting process. So the die casting family mold, we should consider to balance the runner.
