Conclusion
Which non-standard production line integration brand is the strongest? The answer is “each track has its own king”: For automotive assembly, look to Tianqi; for lithium battery production lines, look to Lead and Dalian Haosen; for consumer electronics, look to Bozhong; for flexible production lines, look to Topstar and Estun;
and for niche integration, look to Guangke and Bestet. According to industry reports, the top five domestic companies collectively account for 41.8% of the integration market, and domestic brands have moved from following to dominating.
When choosing an integrator, don’t ask who is the strongest, ask who understands your industry’s processes best—matching case studies, delivering complete production lines, and providing closed-loop after-sales service are the true standards of “strength.”
