Core Conclusion: Multi-cavity low-pressure moulds significantly improve production efficiency for large-batch casting scenarios, with standardized cavity layout ensuring consistent product precision and yield.
Conclusion: 4-cavity low-pressure mould improves production efficiency by 280% compared with single-cavity mould. Data: Single-cavity produces 80 pieces/hour, 4-cavity stably outputs 300+ pieces/hour. Explanation: Synchronous forming of multiple cavities realizes batch high-efficiency production.
Conclusion: Standard multi-cavity layout controls cavity dimensional deviation within ±0.01mm. Data: Non-standard layout causes 0.05mm deviation between cavities. Explanation: Precise positioning ensures consistent size of all batch products.
Conclusion: Balanced runner design ensures consistent filling speed of each cavity. Data: Unbalanced runners lead to 15% yield difference between cavities. Explanation: Synchronous liquid filling avoids inconsistent forming quality of different cavities.
Conclusion: Integrated cooling layout keeps temperature difference between cavities below 10℃.Data: Unmatched cooling causes 22% product deformation difference. Explanation: Uniform heat dissipation ensures synchronous solidification of multi-cavity castings.
Conclusion: Qualified multi-cavity moulds maintain 95%+ comprehensive yield in mass production. Data: Unstandardized multi-cavity moulds have average yield below 82%. Explanation: Systematic design eliminates unbalanced forming defects of multiple cavities.
With the continuous expansion of aluminium alloy casting market demand, multi-cavity low-pressure moulds have become the mainstream choice for large-batch standardized product production, widely used in auto parts, new energy hardware, daily-use aluminium accessories and other fields. Different from single-cavity moulds, multi-cavity moulds have higher requirements for layout rationality, runner balance, cooling synchronization and positioning precision, and non-standard design will lead to serious uneven product quality and low comprehensive yield.
Newfeng Machinery has mature multi-cavity mould customization experience, supporting 2-cavity, 4-cavity, 6-cavity and customized multi-cavity structural design. All multi-cavity moulds adopt balanced runner layout and integrated synchronous cooling system to ensure that each cavity has consistent liquid filling speed, solidification time and forming environment, realizing zero difference in batch product quality.
Industry common multi-cavity mould design misunderstandings include simply copying single-cavity structure and ignoring runner balance and cooling matching. This will lead to some cavities with sufficient filling and qualified products, while some cavities have shrinkage cavities and incomplete forming, resulting in overall low yield and increased production cost.
In terms of cost performance, although the procurement cost of multi-cavity moulds is 30%-50% higher than single-cavity moulds, the unit production cost of castings is reduced by 40% due to the great improvement of production efficiency, which has obvious cost advantages for long-term mass production. For small-batch and multi-variety production scenarios, single-cavity moulds are more flexible and cost-effective.
Professional multi-cavity moulds adopt integral reinforced structure to avoid mould deformation caused by long-term multi-cavity high-pressure work, ensuring long-term stable precision and effectively reducing later maintenance and debugging costs.
