Product Overview
The component shown features a circular face with multiple openings, side-facing tubular sections and a base with mounting geometry. For housings of this type, manufacturing requirements depend on how these features locate, connect and fit within the final assembly.
Investment casting can form the main body close to its required geometry, while CNC machining establishes specified dimensions on functional surfaces. The casting and machining approach is developed around the approved drawing, material and inspection requirements.
Complex Body Geometry
Circular, tubular and mounting features can be incorporated into a single casting, subject to casting feasibility and tooling review.
Multiple Openings
Opening sizes, positions and orientations can be manufactured to the approved design. Internal geometry is reviewed to determine suitable casting and machining methods.
Machined Assembly Interfaces
Specified faces, bores and locating features can be CNC machined to achieve the required fit with mating components.
Custom Mounting Features
Mounting holes, support sections and base geometry are produced according to the installation requirements defined in the customer drawing.
Drawing-Based Production
Material, dimensions, machining allowances, surface finish and inspection criteria are agreed before production.
Manufacturing Process
Drawing & Engineering Review
We review 2D drawings and 3D models to assess wall thickness, opening geometry, tooling access, casting feasibility and machining requirements. Critical interfaces and inspection datums are identified before tooling begins.
Tooling & Wax Pattern Production
Tooling is prepared to the approved design. Wax patterns are checked for shape, completeness and relevant dimensions before shell building.
Silica Sol Investment Casting
The main housing geometry is formed through silica sol investment casting. The approach to internal features is selected according to their accessibility and complexity.
Casting Cleaning & Preparation
Gates are removed, followed by grinding and cleaning. Castings are checked before further machining or finishing.
CNC Machining
Specified faces, bores, holes and connection features are machined to the approved drawing. Machining operations are planned around the required datums and assembly relationships.
Final Inspection & Packing
Finished components are checked against the agreed inspection plan and packed to protect their surfaces and machined features during handling and transport.
Material Options
Material selection depends on the operating environment, mechanical requirements, corrosion exposure and any specified heat treatment.
• Stainless steels for applications requiring corrosion resistance.
• Carbon steels for suitable general engineering applications.
• Alloy steels where specified mechanical properties or heat treatment are required.
• Duplex stainless steels where the service conditions call for their combination of strength and corrosion resistance.
The exact casting grade and applicable material specification are confirmed during engineering review. The material of the pictured component should be identified from its production records.
Casting & Machining Capabilities
Zeren can evaluate the following operations for custom housing projects:
• Silica sol investment casting
• CNC milling of mounting and mating faces
• CNC turning of accessible cylindrical features
• Boring and reaming of specified openings
• Drilling and tapping
• Machining of locating features
• Deburring and edge finishing
• Surface cleaning and specified finishing
• Heat treatment where required
• Dimensional inspection and material verification
As-cast surfaces and machined areas are defined on the approved drawing. Achievable tolerances depend on the material, geometry, feature accessibility and manufacturing sequence.
Quality Control
Inspection focuses on the dimensions and relationships that affect assembly. Depending on the approved drawing, checks may include:
• Overall dimensions
• Circular face diameter and thickness
• Opening diameters and positions
• Hole spacing and orientation
• Mounting face flatness
• Bore alignment and perpendicularity
• Thread conformity where applicable
• Casting surface condition
• Burr removal on accessible edges
• Material composition
Dimensional reports, material verification and first article inspection can be arranged according to project requirements.
If the housing forms part of a pressure-containing assembly, pressure or leak testing requirements must be specified and reviewed separately before quotation.
