V4 Medical Injection Pen: Metallic-Coated Polymer Housing with 60U Precision for 3.0ml Cartridges

Discover the V4 medical injection pen combining metallic-spray finished polymer housing with high-precision dosing. Engineered for standard 3.0ml cartridges with up to 60 Units (60U) per injection, ISO 11608 compliance, and custom OEM manufacturing.

V4 Medical Injection Pen: Metallic-Coated Polymer Housing with 60U Precision for 3.0ml Cartridges

In competitive pharmaceutical and healthcare markets, delivery devices must strike a balance between premium aesthetics, mechanical precision, and cost-effective scalability. While full-metal injectors offer exceptional tactile appeal, they add weight and increase production costs; standard plastic pens, on the other hand, can sometimes lack a premium medical-grade finish.

The V4 Medical Injection Pen bridges this divide. Built with a high-strength medical polymer casing finished with an advanced metallic-spray coating, the V4 delivers the executive aesthetic and durability of metal alongside the lightweight ergonomics and manufacturing efficiency of engineering plastics.

Core Engineering & Design Highlights

  • Metallic-Coated Polymer Housing: Advanced surface spray metallization technology gives the medical-grade plastic body a sleek, scratch-resistant metallic finish, elevating brand presentation while maintaining lightweight comfort for daily use.

  • Optimized 60-Unit (60U) Dosing Range: Designed to deliver up to 60 Units per single injection (0.60 ml), offering versatile treatment coverage for standard-to-high dosage regimens without requiring multiple injections.

  • Standard 3.0 ml Cartridge Integration: Fully compatible with universal 3.0 ml glass cartridges (ISO 13926-1), making it ready for integration with existing insulin, peptide, and biosimilar fill-finish operations.

  • Precision Mechanical Drive: Features an ultra-smooth lead screw that provides linear plunger advancement, low thumb glide force, and crisp audible clicks for every unit dialed and administered.

  • Bi-Directional Dose Correction: Enables users to safely dial back if they overshoot their intended dose, preventing formulation waste.

Target Therapeutic Applications

With its 60U capacity and broad 3.0ml cartridge fitment, the V4 platform supports multiple clinical protocols:

  1. Diabetes Care: Basal and bolus insulin management where flexible 1U to 60U dose scaling is required.

  2. GLP-1 & Peptide Regimens: Multi-dose therapies requiring consistent weekly or bi-weekly subcutaneous injections.

  3. Endocrinology Therapies: Growth hormone and specialized hormone therapies requiring clear unit markings and fine dose control.

Turnkey OEM/ODM Contract Manufacturing

We partner with global pharmaceutical innovators, generic brands, and medical distributors to supply validated delivery hardware:

  • Custom Metallic Colorways: Metallic silver, champagne gold, matte slate, or custom pantone metallic finishes to distinguish drug strengths.

  • Custom Scale Dialing: Factory dial printing in Units (IU), milligrams (mg), or milliliters (ml) to match your API formulation.

  • Scalable Production: High-volume injection molding, cleanroom assembly, and automated 100% torque and stroke verification.

  • Complete Regulatory Dossiers: Design History Files (DHF), biocompatibility data (ISO 10993), and mechanical test reports ready for regulatory submissions.

Frequently Asked Questions (FAQ)

Q: Does the metallic-spray finish chip or wear off with daily alcohol wipe cleaning?

A: No. The medical-grade metallic topcoat is cured with specialized wear-resistant and chemical-resistant binders, passing standard medical abrasion and disinfectant wipe testing.

Q: Can the V4 pen be set with custom fixed stops instead of 1U increments?

A: Yes. For proprietary formulations, our engineering team can modify the internal gear pitch to provide preset dose increments tailored to your specific therapy.
