The cost of injection mold
Jan 26, 2018

The number of cavities incorporated into a mould will directly correlate in moulding costs. Fewer cavities require far less tooling work, so limiting the number of cavities in-turn will result in lower initial manufacturing costs to build an injection mould.


As the number of cavities play a vital role in moulding costs, so does the complexity of the part's design. Complexity can be incorporated into many factors such as surface finishing, tolerance requirements, internal or external threads, fine detailing or the number of undercuts that may be incorporated.[19]


Further details, such as undercuts or any feature causing additional tooling, will increase the mould cost. Surface finish of the core and cavity of moulds will further influence the cost.


Rubber injection moulding process produces a high yield of durable products, making it the most efficient and cost-effective method of moulding. Consistent vulcanisation processes involving precise temperature control significantly reduces all waste material
