Mold Cost Composition & Quotation Breakdown – Material, Machining, Heat Treatment, Surface Treatment and Project Overhead

Transparent quotation breakdown helps customers understand mold investment, Xinfeng Mold separates mold cost into multiple quantifiable cost components for gravity, low pressure and differential pressure casting molds. Mold steel material cost accounts for 32–40% of total mold price;  cost varies by steel grade, block size and material cutting loss. CNC machining cost accounts for 28–35% of total cost, determined by machining hours, cavity complexity and required dimensional tolerance. Heat treatment and surface treatment represent 8–14% of total mold cost, including quenching, tempering, nitriding or PVD coating processes. Many quotation disputes arise from undefined scope;  statistics show 40% of mold price disputes come from unclear boundary of included and excluded work. Design and simulation cost includes 3D modeling, mold flow simulation and drawing work;  it is charged separately for highly complex castings. Project overhead covers engineering management, in-process QC, mold trial, inspection and document preparation, accounting for 10–15%. Spare parts and packaging / transportation cost are listed as separate line items, which can be excluded if customer arranges transportation. Mold modification after initial quotation is charged separately based on material removal volume, machining time and re-heat treatment needs. Quotation validity period is normally 90 days;  steel price fluctuation beyond this period may trigger price adjustment. For large multi-cavity or multi-core-pull molds, quotation includes separate pricing for replaceable inserts to reduce future modification cost. Payment terms, delivery schedule, acceptance criteria and warranty scope are clearly defined within formal quotation document. Quotation distinguishes prototype mold and mass production mold;  prototype molds use simplified structure and shorter service life design. The quotation also lists excluded items such as customer on-site commissioning travel cost, third-party inspection fee and raw aluminum for mold trial. Mold warranty scope is specified in quotation;  warranty covers manufacturing defects but excludes wear, improper operation and unapproved mold modification.
