We started in 2017 in a rented workshop with 8 people, just trying to ship on time. Our first TPU case batch failed at 30%\u2014a 2\u00b0C temperature mistake warped everything. That year had no miracles, only repeated machine calibrations, written logs, and revised checklists. Dropping mold temperature, tweaking pressure, expanding QC from 5 to 13 items. These weren’t innovations; they were scar tissue.<\/p>\n\n\n\n
In 2019, we pursued ISO certification\u2014not for marketing, but because an auditor’s question (“Where’s the maintenance log?”) exposed our chaos. Now preventive maintenance tops our weekly agenda. Quality control is three layers thick: materials, in-process, final. Each layer fixes a “good enough” assumption that cost us.<\/p>\n\n\n\n
Markets taught us humility. Japan returned a batch over 0.5mm deviation. Europe demanded 5 supplier swaps for eco-compliance. E-commerce wants 48-hour turnaround; supermarkets need 18-month warranties. We plan by the hour now, not by the week.<\/p>\n\n\n\n
“Perfect” is just daily data review in morning meetings. We don’t promise zero defects. We promise traceability\u2014records, root cause, fix. That’s what “We’ll make it happen” means after seven years: a slogan turned into audit trails.<\/p>\n\n\n\n
