We surface constraints early and turn product ideas into practical decisions.
About Us
A manufacturing partner for the next generation of cold plunge brands.
Poplunge brings product thinking, rotomolding experience, and export execution together in Shanghai, China.
Who We Are
Built inside a real manufacturing company.
Poplunge is the cold plunge business of Shanghai Junya Yanshan Technology Co., Ltd. Our roots are in rotational molding machinery, molded product development, and outdoor product manufacturing. That background gives us a practical view of product design: a beautiful plunge still has to mold consistently, carry water safely, integrate equipment cleanly, survive shipping, and perform order after order.
