HOW WE WORK

How to work

To provide high quality vacuum bottles and thermos bottles with reasonable prices is one of  Langdao’s main goals, and is also Langdao’s commitment to the market. It is because of the stable and high quality of our products that most of our customers have turned into repeat customers

Langdao’s high quality is accomplished through

• Utilizing the best materials
• Using written production manual to educate the workers before bulk production and placing the manual in each product line to guide the bulk production
• Applying strict internal quality control standard and procedures

a) Instead of doing only one final quality inspection after the production is finished, Langdao performs multiple internal quality inspections throughout the production process, and this ensures that any potential mistakes will be found and corrected as soon as possible.

b) Langdao apply strict AQL 2.5/4.0 International QC standard. For example, for each single vacuum bottle, Langdao will do temperature tests (this test tells whether or not the vacuum bottle is 100% vacuum insulated) for 3 times – 1^st time before the bottle is polished, 2^nd time after it is polished and before coated, and 3^rd time before the bottle is packed.

All items are strictly designed to meet global quality standards: ROHS, FDA, LFGB, Prop65. Each unit undergoes an extensive testing and quality control procedure.Langdao has a professional and experienced QC team. Every single product is checked in multi rounds of the quality check to make sure that our customer receives only quality finished goods.  Every single product is checked in multi rounds of the quality check to make sure that our customer receives only quality finished goods.
