Customers trust Huijin because they know that we will not participate in production in the event of a conflict of interest and will not infringe any intellectual property rights of the products we produce. This policy of mutual trust, respect and success has enabled us to build and nurture many successful long-term partnerships, some of which have lasted for more than two decades. That's why we have ISO 27001 certification.

All products are subject to strict quality control (QC) at each stage of manufacturing. The QC team uses high-speed, high-precision measurements to ensure that the tolerances and quality of each finished product are consistent.

We carry out in-process and semi-finished product assembly inspection for each key function's failure mode impact analysis (FMEA) to meet the "zero failure" standard. The final test can also include 100% inspection.

What are you still hesitating about?

If your product contains pump or motor, Huijin will be your reliable global manufacturing partner.
