At MIR, we specialize in manufacturing advanced high-precision thinwall moulds with robust designs, minimal core shifting and easy maintenance. Our moulds are available in standard configurations ranging from 2 to 16 cavities, ensuring perfect interchangeability and wall thickness tolerance. MIR also designs and manufactures high-output stack moulds. By stacking two or more parting lines within a single tool, stack moulds dramatically increase cavitation and output without requiring a larger injection moulding machine — delivering significantly lower part cost for high-volume packaging, thinwall and closure programmes. Our stack mould capabilities include 2-level and multi-level configurations, balanced hot runner systems for even fill across all faces, precision-guided plate alignment for consistent shot-to-shot quality, and robust, easy-maintenance designs engineered for long production runs. Whether you need a dedicated stack tool or a combined stack/thinwall solution, MIR delivers production-ready moulds backed by full scientific validation.
