YETI Visits Sealock's Vietnam Facility to Review Soft Cooler Bag Production

A team from YETI recently visited Sealock's production facility in Ho Chi Minh City, Vietnam, for a full-day, on-site review of its custom soft cooler bag line. The visit covered raw material verification, a walkthrough of the cutting department, an on-site check of the high-frequency welding process, a review of production records, and a closing debrief — a routine but thorough quality check within an ongoing partnership.

From Fabric to Cut Panels: Material and Cutting Verification

The visit began at the fabric store and cutting stations. YETI's team and Sealock's technical staff jointly checked the incoming fabric's hand-feel, thickness, and colour match, then reviewed the cut panels one by one — from the main body panels to the reinforced base — confirming that dimensions, grain direction, and batch labelling matched the approved tech pack.

In the Cutting Dept, panels organized by batch number (such as P1000) were laid out for inspection, and both sides cross-checked material issuance records against the production schedule.

High-Frequency Welding: On-Site Verification of the Sealed Construction

The tour continued at the high-frequency (HF) welding station, where YETI observed the cooler body's welding process first-hand. The welding machine's control panel and tooling die were shown and explained, with Sealock's technical staff walking through the weld parameters, the die-pressing method, and how seam sealing is achieved. Finished bodies hanging beside the station showed clean weld lines and the pressure-release valve fitting — this stage is central to a soft cooler's insulation and seal performance, and was a key focus of the visit.

Production Records and Work-in-Progress Review

At the material board beside the cutting area, both sides reviewed the current batch's production record, including the start date, planned quantity, and progress notes. Semi-finished YETI soft cooler bags on the workbench, with main-body assembly and pressure-release valves already fitted, showed the brand marking clearly. YETI's team paid close attention to construction detail and valve-fitting consistency, confirming each point on site with the production staff.

Closing Meeting: Confirming the Next Steps

Following the floor walkthrough, both teams held a closing meeting at Sealock's Vietnam office to review the findings, align on the upcoming production schedule and quality requirements, and confirm the next milestones.

About Sealock's Vietnam Production Base

Sealock operates two production facilities in Ho Chi Minh City, Vietnam, established to give overseas customers a diversified production origin and stable lead times. The Vietnam plants follow the same high-frequency welding standards and three-tier quality system used at the Dongguan headquarters — IQC (incoming inspection), IPQC (in-process inspection), and OQC (outgoing inspection) — to ensure consistency across production sites.
