Printer Ink Sac – Durable, Cost-Effective Replacement Ink Tank
The printer ink sac is a flexible internal tank designed to hold ink inside compatible inkjet cartridges and refill systems. Engineered for longevity and leak-free performance, our ink sacs are cost-effective, versatile, and simple to maintain or swap out when refilling.
Material Options & Compatibility
– Polypropylene (PP), Polyvinyl Chloride (PVC), ABS+PC blends, pure PC or PA6+30%GF for rigid-yet-durable plastic sacs
– Rubber or silicone versions for enhanced flexibility and seal integrity
– Nylon or fabric-reinforced constructions for high-strength, puncture-resistant requirements
These options accommodate a wide range of printer models and brands, ensuring full compatibility with standard inkjet cartridge geometries.
Technical Specifications
– Molding Tolerance: ±0.05 mm for precise fit
– Mold Cavities: 1 or 2 cavities (customizable) using HASCO-standard mold bases
– Core & Cavity Steel: 1.2344, 1.2767, Superplast 400 or other customer-specified grades
– Runner Systems:
• Hot-runner: Needle-nozzle direct gating or hot-tip gating for minimal vestige
• Cold-runner: Tunnel-gate design for cost efficiency
– Production Capacity: High-volume multi-cavity tooling, 1,000,000+ cycles per mold set
Molding & Tooling Details
We employ premium hot-work tool steels and HASCO-standard components to guarantee thermal stability and wear resistance. Multi-cavity configurations and optimized runner design minimize cycle time and material waste while ensuring consistent sac wall thickness and dimensional accuracy.
