Tooling expenses, for example, are often amortized across the entire production run. Higher volumes, therefore, distribute the initial tooling investment across a larger number of units, resulting in a lower per-part tooling cost. Conversely, low-volume production necessitates absorbing the full tooling cost across fewer parts, substantially increasing the cost per unit. Consider the case of a custom enclosure for an electronic device. A production run of 100 units would result in a significantly higher per-unit tooling cost compared to a production run of 10,000 units.
Beyond tooling, production volume impacts material procurement strategies. Larger production runs often enable bulk purchasing of raw materials, resulting in discounts and lower material costs per unit. Furthermore, optimized cycle times and efficient use of resources become increasingly critical as production volume increases. Factors such as machine uptime, process optimization, and quality control procedures gain prominence in maintaining consistent production and minimizing defects. For instance, an automotive component manufacturer producing millions of parts annually can leverage economies of scale to negotiate favorable material pricing and implement sophisticated automation systems to optimize production efficiency.
In summary, production volume is a critical input parameter in financial evaluation tools for plastic moulding. An accurate understanding of the intended production volume is essential for generating realistic and reliable estimations.
