Applications
● Disposable Syringes: The primary application for these plunger rods is in standard hypodermic syringes (ranging from 1ml to 60ml). They provide the necessary structural rigidity to push fluid without bending, while the ergonomic finger flange ensures comfortable handling for nurses and doctors.
● Insulin Pens & Auto-Injectors: For diabetic care and emergency medication delivery, these lightweight yet durable rods are used in pen injectors. The high dimensional accuracy ensures the plunger moves smoothly within the cartridge, delivering precise micro-doses of medication.
● Catheter Tip Syringes: Used in larger volume syringes for wound irrigation or enteral feeding, where the plunger rod must withstand higher force to move viscous fluids without buckling.
Advantages
● Multi-Cavity High-Speed Production
The mold features a high-density, multi-cavity layout (stacked or linear configuration). This design maximizes output efficiency, essential for meeting the global demand for disposable medical consumables.
● Advanced Cooling System
Notice the intricate cooling channels integrated near the cavity surface. For thin-wall parts like syringe plungers, rapid and uniform cooling is critical to prevent warping and ensure the rod remains perfectly straight.
● Precision Guide Pillars & Bushings
The robust guide pillar system ensures perfect alignment between the core and cavity plates during every injection cycle. This eliminates flash and guarantees the concentricity of the plunger rod.
● High-Wear Resistant Steel
Constructed from premium hardened steel (such as S136 or H13), the mold offers superior corrosion resistance and polish ability, ensuring the plastic parts are ejected with a smooth, defect-free surface.
FAQ
Q:How about your quality control?
A:We have professional team to control mold quality, since we realize that quality control is the first priority to run business
Q:What's your lead time?
A:For most mold, 45 to 60 working days (not including Chinese official holidays) after deposit received and mold drawings approved
Q:How long can i get the sample?
A:Depends on your specific items,within 3-7 days is required generally.
Q:What information do you need to provide a mold quote?
A:3D part file (STEP/IGS), 2D drawing with tolerances, material type, estimated annual volume, and injection machine specifications (tonnage, tie-bar spacing).
