Independent Technical Supervision For Overseas Equipment Buyers In Yangtze River Delta

Your Exclusive Local Technical Supervision Team for Custom Equipment Procurement in China

Wuxi Lajee Technology Co., Ltd. was registered in April 2004. Our core team has over 20 years of practical experience in precision component machining and custom automation equipment R&D and manufacturing, with full expertise in full-cycle supervision and quality control for general machinery and petrochemical pressure-bearing equipment.

When sourcing custom automation and petrochemical complete plants overseas, you cannot travel to China to oversee drawing reviews, machining and assembly in person. Hidden risks such as cut corners, design flaws and careless assembly will lead to overseas equipment shutdowns and mass rework losses.

Our engineers have extensive hands-on experience in petrochemical equipment supervision. We deliver full-process quality control for pressure vessels, complete refining plants, custom chemical tanks and petrochemical pipeline fittings in strict accordance with pressure equipment codes. We monitor critical processes including NDT inspection, hydrostatic test and material re-verification throughout production.

24-Hour Seamless Coordination Across Time Zones

We conduct on-site inspections and coordinate equipment optimization with manufacturers during daytime. In the afternoon or early evening, we compile full bilingual real-condition reports and send them to you.

The reports arrive within your local working hours, so you can review all materials promptly and issue new supervision instructions to us or the factory. We will carry out all your requirements on-site the next day, eliminating idle waiting time caused by time zone differences and greatly speeding up overall project progress.

We operate across the Yangtze River Delta (Jiangsu, Zhejiang, Shanghai, Anhui) and always act solely in your interest. We conduct full on-site technical audits without equipment trading or factory commissions.

Service Mode

We avoid costly full-time long-term on-site supervision. Instead, we arrange short-term phased factory visits at each critical milestone-drawing review, component processing, machine assembly and commissioning, supplier visit-typically 1 to 3 days per stage. We conduct inspections, record real conditions, compile reports and leave upon completion. You pay only for actual technical supervision work performed, with no long-term on-site retainers. The four core services below cover all links of equipment procurement supervision, available for separate commissioning.

Three Tiers of Specialists (Deployed on Demand)
