Key Design & Performance Advantages

1. 1×2 Balanced Cavity Layout for Efficient Production

The symmetrical 2-cavity design ensures uniform melt flow, cooling, and ejection for both measuring jugs:

Equal part quality: Identical pressure and temperature distribution eliminate dimensional variation, ensuring consistent wall thickness, spout alignment, and handle fit.
High output efficiency: Doubles production capacity per cycle, reducing unit cost and supporting mid-to-high volume manufacturing runs.
Stable molding process: Balanced filling prevents warpage or shrinkage differences between parts, critical for the jug’s flat base and straight handle.

2. 2-Point Hot Runner System for PP Measuring Jugs

The dual-point hot runner system is optimized for large, thin-walled PP kitchenware:

Balanced filling: Each cavity receives independent, uniform melt supply, ensuring complete filling of the jug’s handle, spout, and curved body without short shots.
No material waste: Eliminates cold runner scrap, reducing raw material costs and simplifying production workflow.
Consistent melt quality: Maintains uniform temperature, preventing PP degradation or discoloration, ideal for food-safe applications.

3. 738H Steel: Durability & Stability for Long Runs

738H is a reliable pre-hardened mold steel, widely used for large plastic molds:

Good toughness & wear resistance: Resists fatigue and abrasion from repetitive PP injection cycles, extending mold service life.
Uniform hardness (HRC35-40): Ensures consistent dimensional stability, even after prolonged use, preventing deformation of the jug’s critical features.
Excellent polishability: Accepts high-quality polishing, creating smooth, glossy surfaces that meet kitchenware aesthetic and hygiene requirements.

4. Full Front & Rear Mold Polishing for Premium Surface Quality

Both mold halves are precision-polished to deliver superior part quality:

Smooth, easy-to-clean surfaces: The polished cavity produces a glossy, stain-resistant jug interior and exterior, ideal for food contact applications.
Reduced ejection friction: The polished core ensures smooth demolding, preventing scratches or deformation on the jug’s handle and spout.
No visible flow marks: The mirror finish hides minor molding imperfections, resulting in clean, professional-looking measuring jugs.

5. PP Measuring Jug Optimization for Kitchen Use

This mold is tailored to the unique requirements of PP kitchenware:

Warpage control: Optimized cooling channels prevent the large, thin-walled jug from warping during molding, ensuring a flat base and straight handle.
Handle and spout precision: Tight tolerances on the handle attachment and spout lip ensure comfortable grip and controlled pouring.
Food-grade compliance: The mold’s smooth, corrosion-resistant surfaces prevent contamination, making it suitable for manufacturing food-safe measuring jugs.

Typical Applications

This mold is ideal for producing high-quality PP measuring jugs for:

Household kitchenware
Food service and catering
Laboratory and industrial liquid measurement
Outdoor and camping cooking accessories

Conclusion

The 1×2 cavity PP hot runner injection mold with 738H steel construction and full mold polishing is a robust, efficient solution for manufacturing premium measuring jugs. With balanced cavity design, durable steel, and high-quality surface finishes, it delivers consistent, food-safe parts for high-volume kitchenware production.
