Changzhou Hongxinyutai Precision Mold Co., Ltd. — a trusted manufacturer established in 2017 with a 1,000–3,000 sqm factory and 51–100 skilled employees — proudly presents our Custom Plastic Molding Service for Reagent Vials. Using FDA-grade raw materials (PP, PE, PET) and advanced high-cavity molds, we deliver precision injection molded vials that meet the stringent demands of the pharmaceutical, diagnostic, and laboratory industries. Each vial undergoes 100% quality control to ensure consistent dimensions, leak-proof sealing, and flawless surface finish. Whether you need standard or fully customized designs, our team provides end-to-end support from mold design to mass production, backed by our TS16969-certified quality management system.
Our reagent vials are engineered for superior chemical resistance, clarity, and mechanical strength. With over 7 years of mold-making expertise, we optimize each project for cost-efficiency without compromising quality. Let us partner with you to bring your custom vial solutions to life.
Key Features & Technical Specifications
- FDA-Grade Materials: Choose from polypropylene (PP), polyethylene (PE), or polyethylene terephthalate (PET) — all compliant with FDA food-contact standards for safe reagent storage.
- High-Cavity Molds: Our multi-cavity tooling (up to 32+ cavities) enables high-volume production with consistent quality, reducing per-unit cost and lead time.
- Precision Injection Molding: Tolerances as tight as ±0.05 mm ensure uniform wall thickness, accurate thread dimensions, and reliable sealing with caps.
- 100% QC Inspection: Every vial is checked for dimensional accuracy, visual defects, and leak tightness using automated vision systems and manual inspection.
- Customization Options: Custom colors (Pantone/RAL), embossing/logos, surface finishes (matte, glossy, textured), and special features like child-resistant caps or tamper-evident rings.
- TS16969 Certified Quality: Our production processes follow TS16969 standards, ensuring traceability, process control, and continuous improvement.
- Sterilization Compatibility: Vials can be autoclaved or gamma-sterilized depending on material choice (PET autoclave not recommended).
- Chemical Resistance: Excellent resistance to acids, alcohols, and organic solvents commonly used in reagent formulations.

Frequently Asked Questions
Q1: What are the minimum order quantities (MOQ) for custom reagent vials?
MOQ depends on the mold cavity count and complexity. For high-cavity molds (16+ cavities), MOQ typically starts at 100,000 pieces. For smaller runs or prototype molds, we can accommodate 10,000–50,000 pieces. Contact us for a custom quote.
Q2: Can you mold vials with a child-resistant cap or tamper-evident feature?
Yes, we can design and mold vials with custom cap geometries including child-resistant (CR) and tamper-evident (TE) features. Please provide your cap specifications or let our engineers recommend a solution.
Q3: Are the materials really FDA-grade? Do you have a certificate?
We use FDA-grade PP, PE, and PET resins that comply with 21 CFR for food contact. A material certificate from the resin supplier is available upon request. Our company holds TS16969 certification; we do not claim FDA registration for our facility, but our materials are suitable for laboratory reagent storage.
Q4: How long does it take to develop a new mold and get samples?
Typical lead time for a new high-cavity mold is 25–35 working days, with sample delivery in 15–20 working days after mold completion. Faster turnaround is possible for simpler designs or existing mold bases.
Q5: Can you print my logo or barcode on the vials?
Absolutely. We offer in-mold labeling (IML), hot stamping, pad printing, and laser engraving. Logos, lot numbers, and barcodes can be added directly during molding or as a secondary operation.
Q6: Do you perform leak testing on every vial?
Yes, we perform 100% air leak testing on all finished vials using automated equipment. This ensures that every vial meets your seal integrity requirements.
Q7: How do you package the vials to prevent contamination during shipping?
We pack vials in cleanroom-compatible poly bags, then in corrugated boxes with foam inserts. For sensitive applications, we can also provide vacuum-sealed packaging or desiccant packs upon request.
Q8: What is your payment term and shipping method?
Common payment terms are T/T (30% deposit, 70% before shipment) or L/C at sight. We ship via FOB (Jiangsu/Shanghai/Shenzhen), CIF, or EXW. For small samples, we can arrange express courier (DHL, FedEx, UPS).
