For quotation, please specify the operating medium, temperature, and any relevant corrosion or mechanical requirements.
Manufacturing & Quality
Each project begins with a review of the drawings and delivery requirements. We confirm casting feasibility, machining scope, and inspection criteria before production.
Design Review
Blade edges, blade roots, section transitions, and hub features are reviewed for casting feasibility. Any proposed design changes are submitted for customer approval.
Casting & Machining
Castings are produced to the approved design, with CNC machining applied to specified bores, faces, and mounting features.
Dimensional & Material Verification
Inspection focuses on drawing requirements and agreed acceptance criteria. Material composition testing and supporting documentation can be arranged as specified.
Additional Inspection Requirements
Please identify any runout, balancing, non-destructive testing, or special documentation requirements before quotation so their scope and availability can be confirmed.
FAQ & Contact
Can you manufacture impellers from our drawings?
Yes. Please provide a 3D CAD model, a dimensioned 2D drawing, the material grade, and the required quantity. We will review manufacturing feasibility before quotation.
Can the shaft bore and mounting surfaces be machined?
Yes. Specified bores, end faces, and mounting features can be CNC machined. Please indicate critical tolerances and reference datums on the drawing.
Which materials can be used for corrosive environments?
Material suitability depends on the operating medium, temperature, and service conditions. Please provide your specified grade or application requirements for review.
Can you supply finished impellers ready for assembly?
We can quote machining and surface finishing to your specifications. Any balancing, testing, or final acceptance requirements must be confirmed as part of the supply scope.
What information is needed for a quotation?
Please send your drawings, material specification, order quantity, surface finish, and inspection requirements. Include any critical assembly dimensions and delivery requirements.
Send us your drawings and specifications for a review of casting feasibility, machining requirements, and pricing.
