Sealable Glass Vials Manufacturers

What We Manufacture

Ousibei specializes in the research, development and production of glass packaging materials. Our factory operates 20 dual production lines in two sections: 10 full-process lines for soda-lime glass oral liquid bottles and 10 full-process lines for neutral borosilicate tubular vials. Each line covers glass tube forming, bottle production, annealing, inspection, packing and warehousing without intermediate outsourcing.

• Capacity: 120 pcs/min per forming machine; 2.88 million pcs/day at full load; 864 million glass bottles/year based on 300 production days.
• Materials: Soda-lime glass, low borosilicate, medium borosilicate and high borosilicate glass.
• Forming: Multi-station rotary forming at 1200–1450 °C with servo-controlled wall thickness; bottle mouth tolerance to ±0.03 mm.
• Annealing: Continuous mesh belt furnace, 580–620 °C for 2–3 hours, with slow gradient cooling to eliminate internal stress.
• Inspection: High-speed vision systems check height, outer diameter, inner mouth diameter, wall thickness and bottom concavity; final inspection screens 77 defect types.

Our Product Range and Application Fit

Each container family is engineered for a defined filling, sealing and sterilization route. The table below maps our supplied range to typical contents and closure systems.

Configuration Options

We develop each container around the filling line, closure system and sterilization route. Configuration choices include:

• Capacity: 1 ml to 100 ml, covering single-use, sample, oral liquid and fragrance formats.
• Neck structure: screw neck, vial-type crimp neck, tubular glass, straight body, special-shaped, curved neck and thick-wall designs.
• Glass material: soda-lime, low borosilicate, medium borosilicate or high borosilicate, selected by thermal and chemical exposure.
• Surface finishing: screen printing, hot stamping and spray coating for brand identification.
• Compatibility: bottle structure and dimensional design matched to filling lines and closure systems.

Quality Control and Acceptance

Inspection is embedded at each process step. After forming, vision cameras verify bottle height, outer diameter, inner mouth diameter, wall thickness and bottom concavity, and automatically reject out-of-tolerance bottles. After annealing, a final inspection machine screens for 77 defect types including cracks, bubbles, black spots, stones, chipped mouths and glass particles.

Each carton receives a unique traceability QR code recording the forming machine, batch number and production time. Defective bottles are crushed and recycled back to the remelting workshop. We can supply testing reports with sample development and mass production, and finished products undergo 100% inspection according to customer requirements and applicable international standards.

OEM/ODM Development Process

For customers with existing products, we reproduce according to drawings or samples. For new packaging concepts, we support joint development based on target market and application scenario. The process runs through six stages:

1. Technical requirement discussion
2. Material and structure proposal
3. Mold design and development
4. Sample production and testing
5. Client confirmation
6. Mass production and delivery

Standard products can be supplied at lower MOQ for trial orders. Customized product MOQ is evaluated against structure, mold complexity, material requirements and production process.

Installation, Maintenance and Serviceability

Our containers are designed for standard filling, capping and sealing equipment. Bottle mouth dimensional tolerance to ±0.03 mm supports reliable crimp sealing and stopper fit. Before filling, bottles should be washed, dried and sterilized; amber versions are recommended for light-sensitive formulations. Storage in a cool, well-ventilated area away from direct sunlight preserves glass quality. We provide technical support for line compatibility and can discuss spare parts and replacement supply as part of the project scope.

Information We Use to Configure Your Solution

To prepare an accurate configuration and quotation, we work from the following project inputs:

• Container type and target capacity (ml)
• Content type, pH range and light sensitivity
• Required glass material and color (clear, amber, blue)
• Neck finish and closure system (crimp, screw, pump, dropper)
• Filling line interface and sterilization method
• Annual volume, batch size and delivery schedule
• Surface decoration requirements (printing, hot stamping, coating)
• Applicable standards and documentation needed for acceptance

Frequently Asked Questions

What glass materials can Ousibei supply?

We offer soda-lime glass, low borosilicate, medium borosilicate and high borosilicate glass. Material selection depends on thermal exposure, chemical compatibility and the sterilization route of your filling process.

Can you produce custom bottle shapes and neck finishes?

Yes. We develop screw neck, vial-type crimp neck, tubular glass, straight body, special-shaped, curved neck and thick-wall structures. We also match bottle dimensions to your filling line and closure system.

What is your production capacity and lead time?

Our 20 dual production lines run at 120 pcs/min per forming machine, with daily capacity of 2.88 million pcs and annual capacity of 864 million glass bottles. Lead time is confirmed against order volume and customization scope.

How do you ensure dimensional consistency for crimp sealing?

Servo-controlled forming holds bottle mouth tolerance to ±0.03 mm. Vision inspection checks inner mouth diameter and wall thickness after forming, and final inspection screens 77 defect types after annealing.

Do you provide samples and testing reports?

We support fast sampling and can provide testing reports during sample development and mass production. Samples are produced after material and structure confirmation.

What is the minimum order quantity for custom products?

Standard products can be supplied at lower MOQ for trial orders. Customized product MOQ is evaluated based on structure, mold complexity, material requirements and production process.
