Advantage

Shanghai Special Metal Co., Ltd adopts unique heat treatment to optimize the gear ring structure, to enhance hardness、wear resistance and impact force.

Shanghai Special Metal Co., Ltd uses high strength steel to cast gear ring and optimize rotary kiln to ensure the stability under long working time and prolongs service time.

Shanghai Special Metal Co., Ltd has a strong ability of producing steel casting and we can do mass production of gear ring in short cycle with large amount.

Production Process 

1. Wooden pattern Production 

2. Molding 

3. Pouring 

4. First cleaning 

5. Heat treatment – grinding (inspection)

6. Rough machining (inspection)-finishing machining (inspection)

7. Packing-delivering

Quality assurance 

The fabrication route is governed by the provisions of the implemented Quality System ISO 9001: 2000. The standard documentation ensures the full traceability of every process step: 

• Manufacturer test certificates according to DIN EN 10.204 § 3.1 including chemical composition, mechanical properties and non-destructive examination; 

• Dimensional check supported with a “as-built“ sketch; 

• Record of the heat treatment chart;
