Product Design And Production Service. One of the main reasons why injection molds are expensive is because creating a successful mold tool is a complex process that requires expertise , precision, and labor. The cost of an injection mold tool is influenced by several factors:
Material Cost: Injection molds need to be made from strong and durable materials to withstand the pressure and heat involved in the process. The choice of material, such as different grades of steel or aluminum, depends on the number of parts to be produced. A higher production volume may require a better and more expensive grade of steel.
Mould Construction: Injection molds consist of various complex components that are assembled using manual and automated processes. These components are molded to tight tolerances using specialized machinery like CNC machining and electrical discharge machining (EDM), which add to the overall cost.
Mould Complexity & Aesthetics: The design decisions made for the mold, such as side pull actions, number of cavities, texturing, multi-material shots, tight tolerances, engraving, undercut features, and inserts, can significantly impact the tooling costs. While these design elements may be costly, they can be necessary or beneficial in later stages of the manufacturing process.
Labour Costs: Designing, creating, and assembling injection molds require skilled and trained specialists . The labor-intensive nature of this process, combined with the complexity involved, adds to the overall cost. Choosing cheaper labor options may result in lower upfront costs but can lead to additional expenses in the long run.
Although the initial cost of injection molding can be expensive due to the mold tooling, it is important to consider that the injection molding process itself is highly automated and efficient compared to other manufacturing methods. This efficiency allows for the production of higher volumes of plastic parts, making injection molding one of the most cost-effective manufacturing processes when considering the total manufacturing cost.
