1. Strict material and safety standards
1. Food-grade material certification
High-quality factories use food-contact-grade stainless steel that meets international standards, such as 304 or 316.
2. Compliance of the production process
The factory must pass ISO 9001, FDA or LFGB certifications, and the production process must strictly follow hygiene regulations to avoid contamination in the processing link.
2. Advanced technology and process
1. Vacuum insulation technology
High-quality factories have mastered the mature vacuum insulation layer manufacturing process to ensure that the lunch box can keep warm for up to 6-8 hours, or even longer.
2. Precision mold and welding technology
Use high-precision mold molding to reduce product errors; the welding process is flat and burr-free, which improves sealing and durability.
3. Surface treatment process
Through polishing, wire drawing and other processes, the product looks beautiful and easy to clean, while enhancing scratch resistance.
3. Perfect quality control and testing process
1. Multi-link quality inspection
From the entry of raw materials into the factory to the delivery of finished products, multiple inspections such as size measurement, sealing test, and thermal insulation performance test are required.
2. Simulation of extreme environment testing
For example, high-temperature cooking, freezing, drop test, etc., to ensure the reliability of products in complex scenarios.
4. Flexible customization and service capabilities
1. Support personalized design
High-quality factories can customize capacity, number of layers, color and logo according to customer needs, and even provide packaging design solutions.
2. Large-scale production and fast delivery
With automated production lines and efficient supply chains, the monthly production capacity can reach hundreds of thousands of pieces to meet the needs of batch orders.
3. Professional after-sales response
Provide sample testing, technical support and return and exchange services to ensure smooth cooperation.
5. Sustainable development concept
1. Environmentally friendly production process
Use energy-saving equipment and environmentally friendly materials to reduce carbon emissions and waste.
2. Recycling plan
Some factories provide product recycling or trade-in services to practice the concept of green manufacturing.
If you are looking for a reliable partner, you can give priority to factories with the above characteristics and verify their production environment and qualifications on site to ensure the stability of long-term cooperation.
