Key Advantages
● 1 U Dose Setting With Clear Feedback
Dose selection moves in 1 U increments (0.01 mL) up to 60 U per injection. An indexed dial plus audible or tactile clicks lets the user track each step and correct the setting before injecting.
● Replaceable 3 ML Cartridge Architecture
A 3 mL cartridge sits in line with the holder, piston rod and viewing window. This arrangement keeps plunger force centered during cartridge changes, reduces binding and leaves the remaining medication visible without opening the dose mechanism.
● Patented Mechanism With Defined Service Life
Chinese invention patent ZL202210368411.0 covers the standard mechanism. Its specified service life is three years or 3,000 injections, giving repeat-use programs a clear point for planned replacement.
Customization Options
Development starts with the confirmed 3 mL cartridge and medication concentration. Dose increment, maximum dose, scale movement and piston travel are calibrated together, while cartridge seating and the pen-needle connection are checked against approved drawings and physical samples before housing dimensions are fixed.
The outer body can be changed for the intended grip and brand layout, including the dose window, controls, material, finish and product identification. The agreed supply scope may include molded parts, functional subassemblies or complete pens.
Customization Process
Requirement Confirmation
First, the cartridge, pen-needle interface and dose profile are approved. These inputs become the reference specification for the rest of the project.
Mechanism And DFM Review
The dose train is built around the required piston travel. Engineers review the tolerance stack so the parts can be molded and assembled with consistent movement.
Tooling And Prototype Build
Tooling and functional samples are made to check cartridge loading, dose setting and injection movement in the intended configuration.
Sample Verification
The approved sample is tested at the specified dose points and repeated-use cycles. Engineering changes are completed before pilot production.
Pilot Production
A controlled pilot lot is used to confirm the production window, assembly sequence and inspection method under factory conditions.
Batch Production And Release
Batch production starts after drawings and process controls are released. Final inspection and lot traceability are completed before shipment.
Quality Control
Incoming resin, springs, metal inserts and cartridge-contact parts are checked against released specifications. Assembly inspection covers the dimensions and functions that affect dose delivery, the approved cartridge and the pen needle. Torque, drop, cycle or ISO 11608 verification is performed only when the project plan calls for it. Finished pens are checked for appearance, operation and traceability before packing, and records are kept by production lot.
FAQ
Q1: Can you provide free samples?
A1: Basic reference samples are available. A new molded sample requires confirmed drawings or a supplied reference device, and the tooling fee must be paid before mold development.
Q2: What is the MOQ?
A2: The standard MOQ is one full-container production lot. Mixed colors or models can be considered only when each configuration meets the minimum material-feed and assembly requirements.
Q3: Which cartridge and pen-needle inputs are required for compatibility confirmation?
A3: Send the 3 mL cartridge drawing and physical sample, along with the drawing or sample for the selected disposable pen needle. We verify the holder, piston contact and front connection against these inputs before releasing the design.
Q4: What technical documents can be supplied?
A4: The agreed document package may include product drawings, material declarations, dimensional reports, functional test data, inspection records and batch traceability documents.
