Inspection Process

Inspection throughout our processes

From material sourcing to final outgoing inspection, quality control is carefully monitored. At our facility, the in-process checkup is an overall effort performed at each stage of screw jack and bevel gearbox manufacturing.

A well-equipped workshop in China is here for conducting special tests according to international standards or specifications. Thereby, a high level of customer satisfaction cannot only be achieved but also be extended. There are 4 stages in our quality control system.

Raw material inspection

Raw material inspection

We use high-quality raw materials for all raw materials, 40Cr and 42CrMo for steel, and 9-4, 10-1 for copper to ensure hardness and wear resistance, which makes screw jack have a longer life and higher precision.

  • Material
  • Hardness
  • Size
  • Surface Finish/Scratch

Parts inspection

The accessories such as ball screw, bearing, oil seal, etc., all adopt well-known brands at home and abroad so that the service life of the parts is prolonged and not easy to be damaged. At the same time, all the parts are tested by the library before storage.

Installation debugging

Installation debugging

During assembly, the assembler checks the degree of meshing and quality of the housing, components, etc. to ensure smooth assembly. At the same time, after the assembly is completed, the test machine will be tested to ensure smooth operation of each device.

Shipment Inspection

Finished parts undergo final inspection by our Quality System Manager or shipping personnel prior to any shipment. All parts are visually inspected and are carefully packaged and compactly packaged to ensure their safe arrival to our customers at minimum cost.
