Why Choose a 32 Cavities 5 Gallon Cap Mold with Hot Runner for High-Efficiency Cap Production?

For manufacturers in the beverage and water industries, efficiency, durability, and precision in cap production are critical. The 32 Cavities 5 Gallon Cap Mold with Hot Runner is a premium solution designed to meet the high-volume demands of modern production lines. This mold combines world-class materials, advanced engineering, and precision molding technology to deliver consistent results over a long service life.

The mold cavity is made from S136 steel sourced from Sweden’s ASSAB, offering an HRC of 50-52 for outstanding wear resistance. The mold core, crafted from either S136 (ASSAB) or M310 from Austria, has a higher hardness level of HRC 52-55, ensuring durability and dimensional stability under high-pressure injection. For enhanced durability at critical wear points, the mold core sleeve utilizes DC11 from Japan or W302 from Austria, both heat-treated to HRC 60-62.

The core central ejector integrates beryllium copper with chroming treatment, providing a hardness of 62-64 HRC—ideal for high-precision ejection and long-term reliability. The mold’s ejection system combines ejector plates and ejector sleeves, offering smooth and reliable part release with minimal wear.

At the heart of this system is a hot runner manifold plate made from H13 American steel, ensuring excellent thermal balance and stable flow across all 32 cavities. The remaining mold structure uses P20 steel, a standard choice for its toughness and machinability. This mold is designed to operate with a full hot runner system, enabling reduced cycle times, minimized material waste, and enhanced production efficiency.

Dongkai provides comprehensive support with free spare parts, including a complete core set, one hot runner system, a PID controller system, and spare parts for every 8 cavities—ensuring reduced downtime and maintenance convenience. The mold is backed by a 1-year or 1-million-shot guarantee, with free replacement of defective components due to quality issues within the warranty period (excluding user-related mishandling). With proper maintenance, the mold can last 5 to 6 years, and in optimal conditions, even up to 10 years.

For clients who need hands-on support, Dongkai offers on-site installation and commissioning services. Our experienced technicians can travel to the buyer’s facility to ensure smooth setup and operation, with the buyer covering related travel and accommodation costs.

With its robust construction, long lifespan, and professional after-sales support, the 32 Cavities 5 Gallon Cap Mold with Hot Runner is the ideal investment for companies seeking high-output, low-maintenance cap manufacturing solutions.
