- Barrel Structural Design: Integrate built-in plastic handle, leak-proof sealing thread, anti-slip bottom bump, reserved embossed logo & printing area for ink storage barrels.
- Service Life & Wear Resistance: Adopt thickened mold base with complete quenching and tempering heat treatment, lower abrasion during high-frequency mass production.
- Production Efficiency: Optimize uniform circulating cooling channels + high-gloss fine polishing, realize quick demolding, easy mold cleaning to avoid ink residue contamination.
- Mold Manufacturer Experience: Choose factories mature in chemical ink barrel mold development, familiar with ink packaging anti-leakage structure requirements.
- Budget & Cost Control: Compare quotation based on steel grade, cavity quantity, surface finish and processing craft to match your production budget.
- Equipment Compatibility: Confirm mold clamping tonnage, mounting size fit your existing injection molding machine, compatible with PP/HDPE raw materials for ink barrels.
By comprehensively checking all the above standards, you can purchase a stable, long-service-life and cost-effective 3.5L printing ink barrel injection mold for mass production.
