Custom Investment Cast Automotive Tubular Housing

Automotive components often combine structural, mounting and connection features within a compact geometry.

This carbon steel component integrates a tubular section, main housing, reinforcing ribs and mounting lugs into a single casting.

Silica sol investment casting allows these complex features to be produced close to the final shape while reducing the need for separate fabrication, welding and assembly.

Zeren provides integrated manufacturing from:

Drawing Review → Tooling → Investment Casting → Heat Treatment → CNC Machining → Inspection

Typical Features

• Hollow tubular structures

• Angled tube sections

• Integrated mounting housings

• Reinforcing ribs

• Mounting lugs and holes

• Curved structural transitions

• Machined assembly interfaces

• Custom automotive component geometry

All parts are manufactured according to customer drawings, 3D models and technical specifications.

Why Use Investment Casting?

Automotive components with complex tubular structures and integrated mounting features can be difficult to produce efficiently through machining or fabrication alone.

Silica sol investment casting allows several functional features to be combined into one near-net-shape component.

One-Piece Casting

Tubular sections, ribs, mounting lugs and housing features can be integrated into a single casting, helping reduce welding and assembly operations.

Complex Geometry

Investment casting is suitable for curved surfaces, angled tubes, internal transitions and other three-dimensional structures.

Near-Net-Shape Production

Most of the component geometry can be formed during casting, reducing unnecessary material removal during secondary machining.

Design Flexibility

Wall thickness, tube angle, rib position, mounting features and interface geometry can be customized according to the customer's design.

Engineering Review Before Tooling

Before tooling production, our engineering team can review:

• Wall thickness

• Tube geometry

• Internal passages

• Tube-to-housing transitions

• Reinforcing rib thickness

• Mounting lug geometry

• Casting shrinkage

• Machining allowance

• Potential deformation

• Datum and fixture selection

Early manufacturability review helps improve casting stability and reduce unnecessary tooling modifications.

Carbon Steel Investment Casting

This automotive component is manufactured from carbon steel using silica sol investment casting.

Carbon steel is commonly used for structural and mechanical components requiring a suitable combination of:

• Strength

• Toughness

• Machinability

• Mechanical performance

• Cost efficiency

Heat treatment can also be applied according to the specified material grade and mechanical property requirements.

In addition to carbon steel, Zeren manufactures custom investment cast components in:

• Stainless steel

• Alloy steel

• Duplex stainless steel

• Heat-resistant steel

• Wear-resistant steel

The final material grade is selected according to the customer's drawing and application requirements.

CNC Machining After Casting

Investment casting produces the complex overall component shape, while CNC machining can be used for critical functional areas requiring tighter tolerances.

Typical machined features include:

• Mounting holes

• Bores

• Datum surfaces

• Positioning features

• Assembly interfaces

• Threads

• Connection surfaces

• Critical diameters

Combining investment casting and CNC machining allows complex automotive components to be manufactured efficiently while maintaining dimensional control at important assembly locations.

Inspection from Casting to Finished Part

For automotive components with tubular sections and integrated mounting structures, both casting quality and dimensional consistency are important.

Our quality control can include:

Material Verification

Chemical composition can be checked by spectrometer according to the specified carbon steel grade.

Dimensional Inspection

Inspection methods can include:

• Vernier calipers

• Height gauges

• Bore gauges

• CMM

• 3D scanning

• Custom inspection fixtures

Casting Inspection

Key areas are checked for visible casting defects and manufacturing consistency, including:

• Tube walls

• Rib areas

• Structural transitions

• Mounting lugs

• Internal openings

• External cast surfaces

Machining Inspection

Critical holes, bores, datum surfaces and mounting features are checked against the approved drawing.

Final Inspection

Finished components are inspected before packing for dimensions, surface condition and overall conformity.

Material certificates and dimensional inspection reports can be provided according to project requirements.
