Custom Multi Cavity Molding Exporters & Quotes

The decision is driven by annual projected volume, unit cost targets, part geometry, and press capacity. When production requirements exceed 100,000 units per year, multi-cavity tooling substantially lowers per-part amortization and machine-hour costs. For smaller volumes or frequently evolving designs, single or family cavity tooling may yield a better ROI due to lower initial CapEx.

We deploy advanced Moldflow numerical analysis to evaluate shear rates, weld line positions, and volumetric fill percentages. We implement naturally balanced runner geometry where flow paths to each cavity are identical in distance, diameter, and turn radius. For high-cavitation setups (16+ cavities), we incorporate hot manifold systems with individual nozzle PID temperature controls to fine-tune melt flow behavior.

We manufacture export tooling using internationally recognized standards including DME (inch/metric), HASCO, MISUMI, and LKM mold bases. Wear parts, such as guide pins, ejector pins, cooling nipples, and hot runner nozzles, are sourced to global standard dimensions, allowing your local engineering maintenance teams to quickly source and replace wear components on-site.

With every trial batch, we provide an engineering documentation package: full CMM First Article Inspection (FAI) reports with numbered balloon drawings, resin certificate of analysis (COA) / material certifications, complete mold trial parameter injection logs (melt temp, injection pressure, holding time, cooling cycle), and high-resolution video recordings of the tooling run on the press.

Tool longevity depends on steel selection: Class 101 molds (hardened S136 or H13 steel, >50 HRC) are warranted for over 1,000,000 cycles; Class 102 (pre-hardened P20 or NAK80) are warranted for 500,000 cycles. When Sunmy runs molding production in-house, the mold is maintained and guaranteed for the life of the project with complimentary maintenance, cavity cleaning, and pin replacement.

Detailed engineering quotations accompanied by preliminary DFM insights are delivered within 24 hours of receiving 3D CAD files. Tool manufacturing lead times range from 3 to 4 weeks for rapid prototype/bridge molds, and 5 to 7 weeks for high-cavity, hot-runner hardened steel production tooling, concluding with air-shipped T1 production samples.
