Application-driven review
Application, working medium, load, temperature, corrosion, wear, and assembly conditions are reviewed before material and process direction are confirmed.

Custom Heat- & Corrosion-Resistant Castings
KTECH reviews custom casting projects where heat, corrosion, thin-wall structure, complex internal passages, machining stability, or defect control are major project risks. Typical review scope can include pump bodies, double-suction or other impeller castings, stainless-steel components, hydraulic-retarder parts, and severe-service industrial structures.
Project Review Focus
Confirm Structure, Material, Process and Quality Requirements
Material and process
Stainless steel, heat-resistant cast steel, ductile iron, CGI and other specified materials can be reviewed together with casting process, mold, core, machining, and inspection planning.
Thin-wall and batch quality
Thin-wall filling, complex internal geometry, dimensional stability, leakage risk, surface defects, traceability, and inspection records are considered for batch production.
Suitable Project Types
Projects Ready for Engineering Review
Stainless-steel pump and impeller castings
For pump bodies, double-suction impellers, water-pump or industrial impeller parts where corrosion resistance, thin-wall geometry, balanced structure and machining requirements matter.
- Material grade such as project-specific 304 stainless
- Thin-wall / complex geometry
- Machining and dimensional control
Heat-resistant industrial castings
For parts exposed to heat, thermal cycling, oxidation, load, exhaust-related or other severe working conditions.
- Temperature range
- Thermal cycling
- Material direction
Corrosion-resistant and complex parts
For projects where corrosion, fluid contact, complex internal passages, defect sensitivity or machining-critical features affect material and process choice.
- Corrosion medium
- Internal passage / core design
- Inspection scope

Quality and Delivery Review
Inspection, Documents and Shipment Requirements by Project
Feasibility and filling review
KTECH reviews casting method, material, thin-wall filling, core design, feeding, machining, and inspection according to product risk. Low-pressure or counter-gravity casting can be evaluated where geometry and material make it suitable.
Material confirmation
Material direction is confirmed by target performance, temperature, corrosion, wear, load, machinability, inspection and cost requirements.
Inspection planning
Dimensional inspection, material report, hardness, leakage test, surface review, traceability, and project-specific documentation can be discussed by project.

FAQ
Can KTECH review stainless-steel impeller casting projects?+
Yes. KTECH has existing stainless-steel impeller-related project and technical assets. A new project should still be reviewed by material grade, geometry, wall thickness, working medium, machining, inspection requirements and annual volume before process direction is confirmed.
Can 304 stainless steel be reviewed for pump or impeller projects?+
Yes, when 304 stainless steel matches the actual corrosion, mechanical, casting, machining and service requirements. The final material direction should be confirmed from the project specification rather than selected by keyword alone.
Is a photo enough for custom casting quotation?+
Photos help initial screening, but drawings, dimensions, material, working conditions, inspection requirements, and volume are usually needed for meaningful quotation.
