Manufacturing in Sanxia, Taiwan
History
1976 Founded in Zhonghe as an OEM supplier.
2002 Moved to Hengxi, Sanxia.
2011 Second assembly plant.
2018 Baiji plant opens; ISO 9001.
2023 Suzhou subsidiary.
2026 Kaohsiung office.
Production mix
100% made in Taiwan. OEM is 5%; the rest is WEISUN-brand equipment, from standard hot-air ovens to automated clean low-O2 systems with AGV/EFEM loading, all built in Sanxia.
- High temperature: hot-air processes up to 500°C, 600°C custom; reinforced inner chamber resists distortion.
- Cleanliness: door back panel stays flat under heat; with HEPA, up to ISO 14644-1 Class 4.
- Insulation: four layers keep the shell cool during sintering up to 1200°C.
- Pressure: debubbling under pressure up to 10 kgf/cm² working; vessel meets Taiwan, China and Vietnam codes; door opens only when fully vented.
- Factory testing: mobile line test units ship assembled and tested; on site, just position, power and test-run.
- Recycling: 60% recyclable body materials.
ERP since 2017; PLM and CRM since 2023 for schedules, drawing versions and project records.
