Em Diller, we take pride in using a precise and well-managed process to produce premium stainless steel insulated bottles. If you’re curious about how we make insulated bottles at Diller Factory, you’ll find that to guarantee safety, longevity, and superior insulation performance, each bottle we produce goes through several production steps. This is how we make insulated bottles at Diller Factory, starting with the raw materials and ending with the packaging.
1. Choosing the Raw Materials
Our manufacturing process begins with carefully selected stainless steel, typically 304 or 316 grade, which is renowned for its ability to withstand corrosion and ensure food safety. Understanding how we make insulated bottles at Diller Factory involves ensuring that every bottle satisfies global health and quality standards, as we only source certified materials.
2. Slicing
According to the bottle design, the stainless steel sheets are cut into the proper sizes. Consistency is guaranteed, waste is decreased, and a consistent bottle shape is established through precision cutting, reflecting the meticulous process of how we make insulated bottles at Diller Factory.
3. Extending
Hydraulic presses are used to stretch the cut metal pieces into the basic bottle shape. Maintaining wall strength and thickness, which are essential for adequate insulation, calls for careful control during this step.
4. Forming
We refine the bottle’s body shape after stretching. In order to give each bottle a neat and ergonomic design, this step entails trimming and forming to ensure the surface is symmetrical and smooth.
5. Cleaning
After that, we give the bottle bodies a thorough cleaning to get rid of any remaining forming-related residues, such as oil and metal dust. Strong bonds during subsequent processes, such as welding and coating, are ensured by clean surfaces.
6. Inner and outer layer welding
Our insulated bottles have two walls. To create a sealed vacuum space that efficiently regulates temperature, we precisely weld the inner and outer layers. For the welding to truly perform as insulation, it must be completely airtight.
7. Extraction by Vacuum
To create a vacuum, we then remove air from the space between the two walls. The secret to keeping drinks hot or cold for hours is this vacuum layer. Every product is consistently insulated thanks to our state-of-the-art vacuum extraction machinery.
8. Shining
The bottles are polished to get rid of flaws and give them a glossy, reflective finish after being vacuumed. Additionally, polishing facilitates subsequent surface treatments like powder coating or painting.
9. Testing of Temperature
We test random samples for temperature before proceeding. By evaluating the insulation effectiveness, these tests make sure every bottle meets Diller requirements.
10. Powder coating or painting
After that, we apply exterior coatings for both protection and aesthetics. Bottles may be laser-engraved, powder-coated, or spray-painted, depending on the model. We make use of durable, safe, and environmentally friendly materials.
11. Examination
Every bottle is put through a rigorous quality inspection, which includes surface quality evaluation, vacuum retention checks, and leak tests. Understanding how we make insulated bottles at Diller Factory is crucial, and we ensure that only perfect products advance to the following phase.
12. Packaging
Lastly, we package the bottles with care for delivery. Our packaging procedure is made to ensure that the bottles are delivered to our clients worldwide without being scratched or damaged during transit.
Our Dedication
As a skilled manufacturer of water bottles, we know that safety and quality are paramount. Each stage of this process reflects our endeavor to develop goods that consumers can rely on and enjoy using on a daily basis. We prioritize accuracy, accountability, and sustainability in everything from material selection to packaging.
