What These Part Examples Demonstrate


Quality control is applied throughout wax pattern production, casting, machining and final inspection according to project-specific requirements.

Complex Cast Structures
Investment casting can form non-standard housings, brackets, connectors, manifolds and structural components with ribs, bosses, curved profiles and integrated connection features.
Internal Passages & Multiple Ports
Manifold bodies, connectors and fluid-related components may include internal passages and multiple connection ports that require suitable tooling and stable casting control.
Machined Flanges & Sealing Interfaces
Flange faces, sealing areas, cover interfaces and connection surfaces can be CNC machined according to drawing tolerances and surface-finish requirements.
Precision Bores, Threads & Grooves
Critical bores, threaded ports, grooves and mounting holes can be machined and inspected to support fitting, sealing and final assembly.
Corrosion-Related Material Requirements
Stainless steel and duplex stainless steel components can be evaluated according to the actual medium, chloride exposure, temperature, pressure and mechanical requirements.
Finished Component Delivery
Parts can be supplied with CNC machining, heat treatment, polishing, passivation, blasting, coating or other suitable secondary processes according to the drawing and application.

From Drawing to Finished Petrochemical or Marine Part

Our manufacturing workflow combines casting and secondary operations according to the structure, material and inspection requirements of each custom component.

Investment casting, CNC machining and inspection of petrochemical and marine steel components
01 Drawing & Service Condition Review
Review part geometry, material grade, working medium, wall thickness, machining areas, tolerances and estimated quantity.
02 Tooling & Pattern Preparation
Prepare production tooling, prototype patterns or other suitable pattern solutions according to the project stage.
03 Investment Casting
Produce complex steel components through silica sol lost-wax investment casting.
04 CNC Machining
Machine flanges, sealing faces, bores, threads, grooves, holes, mounting surfaces and other critical features.
05 Heat Treatment & Surface Finishing
Apply suitable heat treatment, cleaning, polishing, passivation or other finishing processes according to the material and drawing.
06 Inspection & Delivery
Inspect dimensions, material, machined areas, surface condition and agreed quality requirements before packaging and shipment.

Materials Used for Petrochemical & Marine Part Examples

Material selection depends on the working medium, corrosion exposure, chloride level, mechanical load, temperature, machining requirements and applicable material standards.

Steel bars, material samples and finished cast components prepared for material verification
Stainless Steel
Used for corrosion-resistant fittings, housings, brackets, connectors and fluid-related components requiring stable machining and suitable surface quality.
Duplex Stainless Steel
Used for components exposed to more demanding chloride-containing, seawater, marine or corrosive industrial environments where increased strength and corrosion resistance are required.
Carbon Steel
Used for structural supports, brackets and housings where strength, machinability and cost efficiency are priorities. Protective coatings may be required for corrosive or outdoor service.
Alloy Steel
Used for mechanically loaded components requiring improved strength, toughness, wear resistance or suitable heat-treatment response.
Final material grades are confirmed according to customer drawings, service conditions, mechanical-property requirements and applicable standards.
