In-Depth Analysis of the Cost Differences in Injection Molding: Exploring Technical Factors from Thousands to Millions

The Impact Mechanism of Mold Structure and Product Complexity on Costs

The complexity of product structure is the primary factor determining mold costs. When a product only requires simple forming functions, such as ordinary plastic storage boxes or pen holders with straightforward structures, its mold design only needs to consider basic single-cavity structures and simple parting lines to meet production requirements. Such molds do not require complex side core pulling mechanisms, nor are there precise holes or special demolding requirements; therefore, processing difficulty is low, and opening costs typically remain within a reasonable range of thousands to tens of thousands.

However, when faced with products like automotive bumpers or large home appliance shells that have complex geometries, the difficulty in mold design will increase exponentially. These products often require multiple slider mechanisms, inclined ejection systems, and hot runner devices. For example, an automotive dashboard mold may need to integrate dozens of precisely fitted core-pulling mechanisms; each mechanism requires an independent drive system and precise position control. Medical device molds also have stringent surface finish requirements that must ensure no burrs exist while avoiding any designs that could harbor bacteria. These special requirements can cause the opening costs for complex molds to rise into hundreds of thousands or even millions.

The complexity in designing parting lines also significantly affects mold costs. Flat parting structures like ordinary cup lid molds have relatively simple processing techniques mainly using conventional milling and electrical discharge machining (EDM). However, for toys with intricate curved surfaces requiring molding processes involving five-axis CNC machining centers for precision engraving along with complicated ejector pin systems and push plate mechanisms for smooth demolding adds significant cost increases directly reflected in higher overall expenses.

Economic Considerations on Physical Parameters & Production Efficiency

The physical dimensions of a mold are another key dimension affecting cost. Small molds such as those used for mobile phone cases usually measure within 300mm×300mm; this not only reduces material usage but also shortens machine time occupancy during processing—thus keeping total costs under tens of thousands. Conversely large-scale molds like refrigerator door panels often exceed 1.5m×2m where just high-quality tool steel raw materials might reach several tens thousand yuan alone combined with specialized equipment needed further pushes total expenditures easily beyond 500k mark.

Cavity count directly relates both production efficiency & economic viability associated respectively between single cavity versus multi-cavity setups—the former being simpler/cheaper suited primarily towards sampling/small batch runs whereas latter type exemplified by efficient production systems needing up-to sixty-four cavities ensures dimensional consistency at micron-level accuracy thereby greatly reducing per-product pricing particularly advantageous during mass manufacturing scenarios.
