Advanced Mold Design & Manufacturing Features
1. Gas-Assisted Molding Technology
The mold utilizes gas-assisted injection molding, a specialized process that injects high-pressure nitrogen gas into the molten plastic during the molding cycle. This creates hollow sections within the thick-walled areas of the tray, delivering three core benefits:
Lighter Parts: Reduces overall part weight without compromising structural integrity.
Stronger Parts: The gas channels form reinforced, rib-like structures that enhance rigidity and impact resistance.
Cost-Effective: Minimizes material usage, shortens cycle times, and eliminates the need for secondary structural reinforcements.
2. Premium 718H Mold Steel Construction
Built with high-quality 718H pre-hardened mold steel, this tooling offers excellent toughness, thermal stability, and wear resistance. This makes it ideal for continuous production cycles, ensuring long-term dimensional accuracy and surface quality, even with the complex gas-assisted molding process.
3. 1*1 Cavity Layout & Submarine Gate
The 1*1 single-cavity design is fully focused on producing a single high-quality tray part per cycle, allowing for precise control over every aspect of the molding process. The submarine gate system feeds material through hidden channels, leaving no visible marks on the critical exterior surface of the medical tray, ensuring a clean, professional appearance suitable for healthcare environments.
4. High-Gloss Polished Surface Finish
Both the cavity and core surfaces are precision-polished to a high gloss, directly addressing the requirements for clean, easy-to-clean medical equipment. This finish also improves mold release, reduces surface defects, and enhances the overall aesthetic quality of the finished tray.
5. Optimized Cooling & Cycle Efficiency
The mold is engineered with strategically placed cooling channels, working in conjunction with the gas-assisted process to ensure uniform and rapid cooling. This design shortens cycle times, prevents uneven shrinkage and warpage, and maintains tight dimensional tolerances on critical features.
Material Adaptability & Core Advantages
ABS plastic is widely used in medical applications due to its excellent impact resistance, dimensional stability, and ease of sterilization. Combined with gas-assisted molding technology, this mold unlocks the full potential of ABS for medical trays:
Lightweight: The gas-assisted process significantly reduces part weight, making the tray easier to handle and transport in clinical settings.
Enhanced Strength: The hollow, gas-formed channels create a rigid, reinforced structure that resists bending and impact.
Cost-Effective: Reduced material consumption and shorter cycle times lead to lower per-part costs, making the tray more affordable for healthcare providers.
High-Quality Surface: The polished finish and hidden gate ensure a clean, mark-free surface that meets medical hygiene standards.
