1. Product Overview

2. Product Specifications & Parameters

2.1 Core Specifications

2.2 Functional Features

• Controlled Pouring: Precision spout design reduces splashing and controls flow rate (100ml/min for liquids like oil).
• Dust & Insect Protection: Secure cap seals tightly to prevent contamination during storage.
• Easy Installation: Twist-on thread design - no tools required (installs in 5 seconds).
• Reusability: Durable PP construction allows 500+ uses with proper maintenance.

3. 3D Drawing Details

3.1 3D Drawing Inclusions

• Views Provided: Isometric view, top view, cross-sectional view, and exploded view (showing spout, cap, and gasket assembly).
• Key Annotations: Thread dimensions, sealing gasket thickness (1.5mm), spout angle (45° for optimal pouring), and cap closure mechanism.
• File Formats: Available in STL (for 3D printing), STEP (for CAD editing), and high-resolution PDF (for quick review without special software).

3.2 3D Drawing Access & Customization

• Custom Adjustments: Modify thread sizes, spout length, or color in 3D models (3 working days for revisions; free for bulk orders ≥10,000 units).
• Use Cases: Clients use 3D drawings for:
  • Verifying compatibility with their bottle designs.
  • Creating marketing materials (product videos, catalogs).
  • Quality control checks during bulk production.

4. Production Process Flow

4.1 Raw Material Sourcing & Inspection

1. Material Selection: Procure FDA-grade PP resin (recyclable grade) and food-grade silicone from certified suppliers (with batch-specific test reports).
2. Eco-Friendly Focus: PP resin contains 30% recycled content (meets ISO 14001 standards) without compromising durability.
3. Testing: Third-party labs (SGS) test raw materials for BPA, heavy metals, and chemical leaching (results provided with bulk orders).

4.2 Injection Molding (Pour Spout & Cap)

1. Mold Preparation: Use precision CNC-machined molds (tolerance ±0.02mm) for spout and cap components.
2. Molding Parameters:
   • PP Melting Temperature: 180-220°C
   • Injection Pressure: 60-80MPa
   • Cycle Time: 25-30 seconds per unit (spout + cap)
3. Color Integration: Add food-safe color masterbatches (black, white, green) during molding for uniform pigmentation.

4.3 Silicone Gasket Production

1. Mixing: Blend silicone rubber with food-grade vulcanizing agents (ratio 100:2) to ensure elasticity.
2. Compression Molding: Cure gaskets at 170°C under 12MPa pressure for 4 minutes (ensures heat resistance and seal integrity).
3. Trimming: Remove excess flash to ensure gaskets fit perfectly into spout grooves.

4.4 Assembly & Quality Checks

1. Automated Assembly: Robotic arms insert gaskets into spouts (accuracy ±0.1mm) and attach caps for final product pairing.
2. Multi-Stage QC:
   • Dimensional Check: 5% of units tested with calipers to verify thread and diameter specs.
   • Leak Test: 10% of units filled with water, sealed, and inverted for 24 hours (no leakage allowed).
   • Functional Test: Manual opening/closing cycle (50 times) to ensure cap durability.

4.5 Packaging

• Eco-Friendly Packaging: Units are packed in recyclable cardboard boxes (no plastic fillers).
• Bulk Packaging: 500 units per carton (dimensions: 40cm × 30cm × 25cm; gross weight: 7kg).
• Labeling: Each carton includes recycling symbols, material composition, and batch number for traceability.

5. Quality Assurance

5.1 Testing Standards

• Material Safety: Annual third-party audits (SGS) confirm compliance with FDA 21 CFR 177.1520 (PP) and LFGB §30 (silicone).
• Performance Testing:
  • Durability: Accelerated aging tests (exposure to 60°C for 1000 hours) confirm no material degradation.
  • Chemical Resistance: Tested with common liquids (oil, vinegar, alcohol) - no swelling or leakage after 30 days.
  • Recyclability: Verified by ISO 14021 certification (100% recyclable in standard plastic streams).

5.2 Quality Control Measures

• In-Line Inspection: Cameras monitor molding processes to detect defects (e.g., cracks, uneven threads) in real time.
• Batch Traceability: Each unit is linked to raw material batches and production timestamps via QR codes (accessible to clients).
• Continuous Improvement: Monthly review of customer feedback to refine production (e.g., adjusting spout angle for smoother pouring).

5.3 Warranty & After-Sales Support

• Warranty: 1-year warranty against manufacturing defects (free replacement for faulty units).
• Support: Dedicated team responds to quality inquiries within 12 hours; technical documents (3D drawings, test reports) provided on request.

6. Application Scenarios

• Household Use: Repurpose bottles for storing cooking oil, vinegar, syrup, or cleaning liquids (mess-free pouring).
• Food Service: Cafes, restaurants, and catering businesses use it for bulk condiments (ketchup, mustard) to reduce packaging waste.
• Industrial Settings: Ideal for non-toxic industrial liquids (detergents, coolants) - controlled pouring minimizes spills.
• Eco-Projects: Promoted by environmental organizations for community recycling initiatives (turning waste bottles into functional tools).
