Custom seeder discs are offered in EN-GJS-500-7 ductile iron through sand casting followed by machining for agricultural machinery. Geometry and finished interfaces should follow the actual seeder assembly drawing. Colors can be specified to customer requirements.
Confirm how the disc fits the seeder
The size reference is 330 × 30. Specify its unit and the role of each dimension on the controlled drawing. Identify the mounting interface, locating features and relationships to adjacent components. Describe the agricultural working conditions and any hardness or surface requirements relevant to the selected disc design.
Control the seeder disc mounting dimensions
Show which surfaces require machining and the dimensional limits they must achieve. Mark governing datums so related interfaces can be assessed in the intended assembly relationship. State the supplied condition in which those dimensions and surface criteria will be accepted, rather than relying only on the casting and machining process names.
Prepare the design and documentation package
For the seeder-disc design, send 3D, CAD, DWG, STEP or PDF inputs. Mark the governing disc revision across the supplied files. Establish the actual documents and applicable component or service scope for the ISO 9001:2025, RoHS and REACH references.
- Provide the selected material specification and disc drawing.
- State quantity, color and initial component-approval requirements.
- Agree inspection coverage and the records needed for acceptance.
Hard wooden-case packing is listed for the completed discs. Keep approved design changes connected to the same seeder interfaces, machined dimensions and supplied condition when requesting repeat production.
