Safety must be a primary consideration of the mold designer. How can a mold, or any heavy mold part, handled safely? No person should repeatedly lift parts heavier than 20KG or any part which is awkward to handle, regardless of weight, without some mechanical assistance, such as a hoist.
Not only should nobody get hurt when handling a mold or mold part, but the mold maker has a legal responsibility for any accident that may arise because of an omission or poor design. Where it is not possible to provide a suitable safety feature, at least a clearly visible warning label or name plate must be provided to inform of the possible hazard and it’s consequences.
There are four situations during which part or all of the molds is handled.
1) Machining a mold part (plate, heavy cavities and cores),
2) Assembling the mold ( servicing and maintenance),
3) Mounting the mold in a machine,
4) Operating the mold.
