When planning OEM custom mold development brands need to balance mold material grade, service life and upfront investment budget according to expected order volume, high-hardness steel molds suit long-term repeated bulk OEM orders with thousands of annual shipments while standard aluminum alloy molds are cost-effective for small-batch trial customized products, clients can share existing mature structural designs to simplify mold processing and shorten development lead time, adding unified interchangeable mold inserts for different color or logo variants avoids opening separate full sets of molds and greatly reduces total tooling expenses, our engineering team provides free mold structure optimization suggestions to lower post-production defective rate, all mold modification demands are recorded and confirmed in writing before processing to prevent unexpected extra charges during OEM mass production.
