About Us

Reliable industrial refrigeration manufacturing partner

Xinxiang Finway Technology Co., Ltd. is a factory-direct manufacturer of refrigeration evaporators, wire-on-tube condensers, copper tube aluminum fin heat exchangers, and precision sheet metal parts. We support OEM customers across heat pumps, commercial display cabinets, cold rooms and cold chain, RV and marine refrigeration, medical equipment, and industrial cooling.

Production is organized for repeatable OEM quality: tube processing, automatic welding, brazing, 100% nitrogen leak testing, anti-corrosion coating, sheet metal fabrication, assembly, and export packaging are controlled through standardized checkpoints. Engineering support covers drawing review, thermal selection, prototyping, and stable batch supply.

From drawing to prototype in days: custom sizes, tube and fin geometry, coatings, packaging, and branding are all configurable for your project.

Factory Capability

Stable production support from prototype to repeat orders

Our manufacturing process covers tube processing, automatic welding, brazing, 100% nitrogen leak testing, sheet metal fabrication, powder coating, OEM assembly, and export packaging — with every batch verified against the same control points.

Quality Control

Inspection checkpoints built around OEM reliability

Refrigeration components need stable dimensions, clean welding, reliable pressure resistance, and packaging that survives transport.

1

Material Inspection

Tube, fin, sheet metal, wire, and purchased parts are checked before production release.

2

Process Control

Key dimensions, welding position, coating preparation, and assembly steps are monitored.

3

100% Nitrogen Leak Test

Every unit is pressure-tested with nitrogen before shipment to eliminate refrigerant micro-leaks.

4

Final Inspection

Appearance, dimensions, quantity, labels, and customer-specific requirements are verified.

5

Packaging Review

Export cartons, pallets, and protective packing are confirmed before goods leave the factory.
