This LSR nipple injection mold is engineered for reliable, high-yield production of food-grade baby nipples. The tool supports wide neck designs and delivers consistent wall thickness through an optimized cold runner layout — producing parts ready for sterilization and further assembly without secondary trimming.
Ideal for manufacturers seeking a turnkey food-safe solution, the mold pairs seamlessly with horizontal LSR injection machines and blow-off demolding stations for automatic ejection.
Cold-runner system: minimizes silicone waste and eliminates visible injection gates on finished LSR nipple.
Flow balancing: LSR injection mold runner and gate geometry ensure silicone uniform distribution across cavities for matched feel and elasticity.
Surface finish & venting: polished cavities and vacuum venting reduce bubbles, producing smooth, hygienic surfaces.
Demolding: integrated ejectors + blow-off (air-blow) interface for automated, smooth demolding and high line uptime. These design choices follow best practices for LSR injection mold used in baby product LSR nipple manufacture.
