Insulated Travel Mug with Straw

We use a laser tube welding machine for the cup body. The heat from laser welding affects only a small area. The weld seam is narrow and deep, so it does not leak easily. After welding, we use an endoscope to check the inside of the weld. We look for holes or incomplete welding. For each batch, we cut open a few cups to check the weld cross-section. If a weld is not good, we adjust the laser power and speed. We have a lot of experience welding both SUS304 and SUS316. These two materials absorb laser energy differently. So we set separate parameters for each. This careful work makes every insulated travel mug with straw reliable.

We test the strength of the weld with a pull test. We cut the welded cup body into strips. Then we pull the strip with a tensile machine. We check if the break happens at the weld or at the base metal. A good weld should be stronger than the base metal. We do three pull samples per batch and record the data. If the pull strength falls below the standard, we stop the line and investigate. We check the welding parameters, material batch, and mold fit. We do not accept weak welds. This gives you a strong insulated travel mug with straw that lasts.

This insulated travel mug with straw has a straw lid. You can drink while walking or driving. The 280ml and 380ml sizes fit most car cup holders. The double-wall design keeps your drink hot or cold for hours. You can also customize the body with paint or powder coat. Add your logo with heat transfer, 3D, or water decal. The laser welding makes sure the cup does not leak from the bottom. Order this insulated travel mug with straw for your next promotion or personal use.
