Lots of individuals take tumblers daily to consume water, coffee, or juice. Lid-fitted tumblers assist in maintaining drinks hot or cold over several hours. When businesses sell such tumblers in the markets, they desire that they be safe, clean and strong. This is the reason why quality control is important. Everichhydro is a well-known wholesale tumblers with lids manufacturer that focuses on quality. This article explains how Everichhydro checks its tumblers to make sure they meet high standards before shipping them out to stores.

Raw Material Check

The quality control process starts before the tumbler is even made. Everichhydro carefully checks all the materials used to make the product. Stainless steel, plastic and silicone are mostly used in the company. Each of these materials is tested to ensure that it is safe, clean and strong. Steel that is rusty or plastic having a peculiar smell will not be used. Only top-grade material is allowed into the factory.

Mold and Shape Inspection

Next, the workers use molds to give shape to the tumbler and lid. These molds must be clean and smooth. Everichhydro checks each mold every day to make sure it is not damaged. A bad mold can make a tumbler that leaks or does not look right. The shape must be even from top to bottom. The lid must fit perfectly on the tumbler. If something is off, the workers stop the machines and fix the problem right away.

Temperature and Pressure Tests

Tumblers are meant to hold both hot and cold drinks. Everichhydro tests each batch to see how well the tumblers hold heat and cold. Some tumblers go through hot water tests. Others are filled with ice and checked after a few hours. If the tumbler cannot hold the temperature, it fails the test. The lid is also tested under pressure to make sure it will not pop off when someone shakes or drops the cup.

Leak and Spill Testing

One of the most important tests is the leak check. A tumbler that leaks will not be useful. Everichhydro fills the tumbler with water, closes the lid, and turns it upside down. If even one drop comes out, that item is taken out of the batch. This is done for many samples in each group. The goal is to make sure customers do not get tumblers that spill in bags, cars, or lunchboxes.

Lid Fit and Lock Check

The lid plays a big role in keeping the tumbler safe and easy to use. Everichhydro checks that each lid fits the tumbler tightly. Some lids come with sliders or locks. These parts are tested by hand to make sure they open and close easily. If the slider sticks or feels loose, the lid is not approved. The company also checks that the lid material does not crack or change shape after use.

Painting and Coating Review

Many tumblers have colors or printed designs. These are done using powder coating or spray paint. The painting must be even and smooth. It should not peel off after a few washes. Everichhydro tests the coating by rubbing it and washing the tumbler several times. If the color fades or flakes off, the tumbler does not pass the quality test. This helps keep the product looking nice after many uses.

Logo and Custom Print Check

For brands that order custom tumblers, the logo or design must be printed clearly. Everichhydro uses machines to check if the print is in the right place. The size and color of the logo must match the order sheet. Any print that looks blurry or off-center is removed. This ensures each tumbler matches what the client expects.

Final Cleaning and Safety Check

All the tumblers are washed and dried before packing. Employees use gloves so that there is no mark or dust on the product. Everichhydro is inspected against sharp edges, loose parts or the smell of glue or paint. A light is also used to check the inside of the tumbler to see whether something has been left behind. The primary concern at this step is safety.

Packing Inspection

Each tumbler is packed in a box or bag. Everichhydro checks that the right box is used. Some tumblers come with a straw or cleaning brush. These items are counted and added. If a piece is missing, the whole box is re-checked. Labels are printed and spelling and clear instructions are checked. Boxes are then packed and put on the shelves to be shipped.

Conclusion

Everichhydro adheres to a robust and diligent procedure to ensure that every tumbler is safe, clean and durable. Raw materials, processing, final packing, etc., are carefully observed by trained employees. Such a degree of attention makes the stores believe in the product. Customers are assured of getting effective and presentable tumblers. This emphasis on quality will remain in 2025 to make Everichhydro prominent in the tumbler market.
