SMARTELL TECHNOLOGY CO., LTD. high-precision syringe molds, engineered specifically for medical-grade injection molding. The new mold series delivers greater durability, accuracy, and stability—meeting the extreme precision required for syringe barrel, plunger, and gasket production.
Syringe molds are fundamentally different from ordinary plastic molds. Because syringes are used for medical injection and drug delivery, their components must meet strict international standards for clarity, safety, dimensional accuracy, smoothness, and sealing performance. This makes syringe molds one of the most precision-dependent mold categories in the plastic injection molding industry.
Unlike general consumer plastic products, syringes must ensure:
Perfect transparency for visual medication check
Smooth inner surface for friction-free plunger movement
Precise dosing accuracy and wall thickness
Stable luer lock / luer slip dimensional fit
Zero flash, zero burr, and no flow marks
Consistent sealing performance between barrel and plunger
Even the smallest dimensional deviation can lead to leakage, inaccurate measurement, or increased friction—making syringe molds far more complex than traditional plastic molds.
Most syringes are produced using medical-grade polypropylene (PP), chosen for its:
High clarity
Biocompatibility
Good toughness
Low friction
Excellent processability
Resistance to sterilization methods (ETO, Gamma, Steam)*
Because the resin must flow smoothly into thin-wall areas, the mold runner system, venting, and gating design require expert engineering.
To meet long-term high-volume production demands, SMARTELL uses top-tier mold steels, including:
S136 (Sweden)
P20
These materials offer:
High corrosion resistance
Excellent polishability for transparency
High hardness & wear resistance
Long mold lifecycle
Easy maintenance
Stable performance during fast injection cycles
With proper maintenance, syringe molds can reach 3 million shots, depending on resin and process conditions.
