How Insulated Stainless Steel Thermos Bottles Are Manufactured？

1. Materials Science & Raw Component Selection

The foundation of a durable, high-performance insulated thermos bottle lies in raw material selection. في جارينو, we strictly enforce international food-safety compliance (ادارة الاغذية والعقاقير, لفغب, يصل, RoHS) to support global brand distribution.

2. Step-by-Step Stainless Steel Thermos Manufacturing Process

• Step 1: Stainless Steel Pipe Cutting & Forming
Raw 304/316 stainless steel pipes are cut into calculated cylinder lengths. Hydraulic bulging and stretch-forming processes shape the body contour, necking, and base indentation.

• Step 2: Dual-Wall Inner & Outer Assembly & Welding
The smaller inner liner is nested precisely inside the larger outer shell. The top mouth and bottom joints are joined using automated TIG (Tungsten Inert Gas) or laser welding to create a sealed chamber.

• Step 3: Vacuum Evacuation & Copper Plating
Air is extracted from the sealed inter-wall gap inside a high-temperature vacuum furnace (reaching over 500°C) until an ultra-high vacuum state (<10⁻³ Pa) is achieved. A microscopic layer of copper is electroplated onto the outer surface of the inner wall to minimize thermal radiation.

• خطوة 4: الاحتفاظ بدرجة الحرارة & Leak Testing
Every batch undergoes rigorous thermal testing. Infrared sensors monitor heat loss after injecting high-temperature water/steam. Sub-standard insulated bottles are automatically purged.

• خطوة 5: Surface Finishing & Custom Branding
Bottles undergo surface treatment such as matte powder coating, UV gradient painting, or rubberized soft-touch finishes. Branding is applied via precision laser engraving, silk-screen printing, or 3D digital printing.

3. تصنيع المعدات الأصلية مقابل. ODM Customization Capabilities for Drinkware Brands

OEM (تصنيع المعدات الأصلية): Produce thermos bottles based on your exact technical drawings, 3D CAD models, volume specifications, and brand color codes (Pantone matching).

ODM (تصنيع التصميم الأصلي): Leverage Jarrino’s in-house design catalog, turnkey product innovations (e.g., integrated wooden bases, ceramic liners, titanium outdoor drinkware), and custom lid solutions.

4. ضمان الجودة, Food Safety & International Compliance

• Material Safety: 100% خالية من مادة BPA, خالية من الفثالات, non-toxic food grade materials compliant with FDA and LFGB standards.
• Structural Integrity: Drop-testing from 1.5 meters, lid thread torque testing, and seal durability testing over 10,000 open/close cycles.
• الأداء الحراري: Guaranteed retention keeping liquids hot (>60°C) for up to 12 hours and cold (<8°C) for up to 24 ساعات.
