Comparison of comprehensive service life of molds with different casting processes and reference for overseas customer mold budget selection | LPDC/CPC/gravity/differential pressure
Wrong process selection and deviation in life expectancy estimation have resulted in budget overruns for 38% of overseas customers and lower than expected returns after production.
The stable service life range of gravity casting H13 mold is 25000 to 40000 mold cycles, suitable for small batches and low added value wheels.
Low voltage LPDC mold, standardized nitriding+cooling control, stable life of 40000 to 70000 mold cycles, suitable for large quantities of wheel hubs and conventional structural components.
The sealing components of differential pressure casting molds are easily consumable, with a lifespan of 35000 to 60000 mold cycles for the cavity body. The continuous investment in spare parts is high, and the advantage of good products is prominent.
The working conditions of the CPC back pressure sealed filling mold are harsh, with a lifespan of 30000-55000 mold cycles for the cavity body, and a short cycle for the matching liquid lifting tube and sealing consumables.
The vacuum assisted LPDC mold accelerates the loss of the nitride layer due to negative pressure water vapor erosion, and its lifespan is reduced by about 15% compared to ordinary LPDC.
Three consecutive production shifts and high-temperature workshops in the Middle East generally result in a 20% to 28% lower lifespan of molds of the same type compared to two workshops in Southeast Asia.
Low pressure die-casting molds (LPDC), reverse pressure casting molds (CPC), differential pressure casting molds for wheel hubs, low-pressure casting molds for wheel hubs, gravity casting molds, motorcycle wheel hub casting molds, structural component casting molds, aluminum alloy wheel hub molds, aluminum casting forming molds, low-pressure casting tooling molds. Many overseas customers only look at the purchase unit price of molds, not including the full life cycle consumables, downtime, and scrap losses. Zhejiang Xinfeng Machinery's selection logic for customers: annual production<80000 pieces, limited budget priority gravity; Annual production of 80000 to 250000 wheel hubs using conventional LPDC; Priority vacuum LPDC for high airtightness new energy structural components; The consistency requirement is extremely high, and the willingness to bear the cost of spare parts maintenance, CPC backpressure is selected. Molds with high unit prices, if they have a high yield rate and minimal downtime, will result in lower long-term cost sharing per unit. Proactively delivering estimated lifespan and spare parts consumption list to customers during the quotation stage significantly enhances customer trust and reduces disputes in the later stages.
FAQ
