Process-Built
When standard models miss your temperature range, chamber size or loading method, WEISUN designs a new machine from the process. We confirm temperature, uniformity, cleanliness, O2, load and factory interfaces, then define structure, airflow, controls and communication. R&D unit since 2010. 2012: special-process baking with a Japanese oven maker. 2013: solar drying with a PV partner. 2016: 530°C clean oxygen-free baking under MOEA SBIR. 2022: ITRI smart baking system.
Key Challenges
Challenge 1: Standard models don't fit
Off-catalog temperature, size or atmosphere; retrofits miss spec.

Challenge 2: Hard to automate
AGV, EFEM and SECS/GEM need several vendors.

Challenge 3: Qualification risk
A failed first unit delays production.

Solution 1: Designed from the process
Built to your temperature, cleanliness, O2 and load.

Solution 2: Integrated at the tool
AGV/EFEM and SECS/GEM integrated at the tool.

Solution 3: Qualify one, then scale
A networking OEM qualified one dual-door oven first.
Track Record
2012 | Electronics special-process baking, with a Japanese oven maker.

2013 | Solar drying, with a PV partner, to raise conversion efficiency.

2019 | AGV unmanned loading: AGV/EFEM, SECS/GEM and PCB ECI, for PCB D/F, solder mask, SAP, bumping, panel fan-out.

2022 | Smart baking system, an ITRI development project.

2023 | Dual-chamber control: two chambers run separate recipes, with waste heat recovery, external cooling and early-warning alarms.

Custom | Taiwanese networking OEM: pre-shipment reliability tests at 90°C for 20 hours unattended. We designed a dual-door hot-air oven to product size and test flow, with local survey, design, build and service.
Project Flow
Six steps:
1 Custom design > 2 Sheet metal > 3 Assembly > 4 QA inspection > 5 Shipping > 6 On-site installation

Design covers market needs, mechanics and controls, Industry 4.0/IoT, energy and safety, and IT integration.

All built in Taiwan. Patents in three areas. Energy recovery: heat-storage heat recovery, faster heat-up, improved preheater. Temperature/airflow: double-layer damper, door-closed airflow adjustment, per-zone real-time control. Special environments: infrared array heating for vacuum.
