Factory Tour — How Your Tumblers Get Made

Inside Our Factory

A real look at how your tumblers get made — from stainless coil to packed carton.

1. Raw Material Storage

Raw Material Warehouse Food-Grade Resin Stainless Steel Storage

FDA-grade SUS304/316 stainless steel coils and food-safe PP/Tritan resin pellets, all batch-traceable from certified suppliers (Tsingshan, BaoSteel, SABIC).

2. Stainless Steel Body Forming

Sunrise Stainless Steel Coil Feeder for SUS304 Tumbler Manufacturing

SUNRISE high-speed coil feeder (≤120 m/min) feeds SUS304 strips into the stamping line. Each strip is laser-checked for thickness uniformity (±0.02mm tolerance).

3. Vacuum Sintering Furnace

Industrial Vacuum Sintering Furnace for Insulated Bottle Production

8 industrial vacuum sintering furnaces (2,000kg load each) bond inner+outer walls at 0.001 Pa, achieving the 12-hour heat retention that defines our tumblers.

4. 6-Axis Robotic Welding

6-Axis Robotic Welding Arms for Stainless Tumbler Assembly

15 ABB-spec 6-axis robotic arms perform precision TIG welding on bottle bottoms — 40,000 welds/day, zero pinhole defects guaranteed via in-line helium leak test.

5. Lid & Strap Injection Molding

Chen Hsong Injection Molding Machine for Tumbler Lid Manufacturing

20+ Chen Hsong PRO and MKS Pro injection molding machines (80T-450T) produce lids, handles, and decorative parts in food-grade PP, Tritan, and silicone.

7. Quality Control & Final Inspection

Factory Quality Inspection Walkway Yongkang Tumbler Workshop

Every batch passes 3-stage QC: visual, leak (water + air pressure), drop test (1.2m). AQL 2.5 standard. Independent QC team reports to a separate manager (not production).
