Verifying a New Large-Format Press Tool Range from Ground Up
ATS Proequipment's existing press tool range covers standard residential and light commercial pipe diameters. To expand into larger commercial and industrial applications, they required a supplier capable of producing large-format hydraulic press dies — from DN32 up to DN150 — with independently verifiable crimping force output and a dimensional verification process their buyers could trust.
Changhong presented a complete product range spanning DN32, DN80, and DN150 press die sizes, alongside the hydraulic tool body and adapter components required to drive them. Rather than taking the factory's performance claims at face value, Luckee arranged for force testing to be conducted at an independent third-party laboratory — Zhejiang Tashan Fluid Control Technology — where peak output was measured live and logged against a calibrated load cell.
The factory also opened their in-house QC laboratory for inspection, revealing a coordinate measuring machine, a Tensile Technologies universal testing machine, battery and electrical test equipment, and a Rockwell hardness tester — a level of metrology capability that goes well beyond what most hydraulic tool manufacturers in the region maintain.
