This carbon steel mounting bracket is produced by investment casting as an integrated structural component with mounting ears, connection features and an open-frame design. Investment casting allows complex geometry and varying cross-sections to be formed in one piece while reducing the need for separate welded components.

Zeren manufactures custom carbon steel brackets and hardware components based on customer drawings and 3D models, with optional CNC machining, heat treatment, surface finishing and dimensional inspection according to project requirements.

Product Overview

One-Piece Cast Bracket for Custom Mounting Applications

The bracket combines an open-frame body, mounting sections and connecting features into a single investment cast component. Its geometry demonstrates one of the key advantages of investment casting: the ability to produce complex structural shapes without assembling multiple separately manufactured parts.

Wall thickness, mounting hole positions, fillets, local reinforcement and machining allowance can be adjusted according to the customer's drawing and functional requirements.

Typical Product Features

  • Integrated one-piece cast construction

  • Carbon steel material

  • Mounting ears and through holes

  • Open-frame structural design

  • Complex contours and transitions

  • Optional CNC machined features

  • Custom dimensions according to drawings

Casting & Machining

Investment Casting for Complex Carbon Steel Brackets

Investment casting, also known as lost wax casting, is well suited for carbon steel brackets with irregular profiles, integrated mounting features and complex transitions. The process can produce a near-net-shape casting before secondary machining is applied to critical functional areas.

For features requiring closer dimensional tolerances, CNC machining can be performed after casting and heat treatment according to the drawing specifications.

Typical Machined Features

Mounting Holes · Bores · End Faces · Locating Features · Threads · Slots · Datum Surfaces

Machining allowances and datum locations can be reviewed during the engineering stage to help achieve stable dimensional relationships between cast and machined features.

From Lost Wax Casting to Finished Bracket

The component can be manufactured through an integrated process covering casting, heat treatment, machining, surface finishing and final inspection. Production requirements are reviewed according to the drawing before tooling and mass production.

Carbon Steel Material

Carbon Steel for Structural and Hardware Components

Carbon steel provides a practical balance of strength, machinability and manufacturing cost for many industrial mounting and structural hardware applications. Different carbon steel grades can be selected according to mechanical property, heat-treatment and service requirements.

Material grades, heat treatment and hardness requirements can be produced according to customer specifications and applicable standards.

Why Carbon Steel?

Good Mechanical Strength
Suitable for many structural and mechanical applications.

Heat-Treatable Options
Mechanical properties can be adjusted according to the selected grade and heat-treatment process.

Good Machinability
Suitable for secondary machining of mounting holes and functional surfaces.

Cost-Effective for Industrial Parts
A practical material choice when stainless steel corrosion resistance is not required.

Surface Finishing Options

Because carbon steel requires appropriate surface protection depending on the service environment, different finishing options can be selected after casting and machining.

  • Black Oxide

  • Phosphate Coating

  • E-Coating

  • Powder Coating

  • Plating

  • Painting

  • Polishing or Blasting as required

Quality Control

Inspection for Cast and Machined Brackets

Critical mounting dimensions, hole positions and mating features can affect assembly performance. Inspection is therefore carried out according to the customer's drawing and specified tolerances throughout production.

Material Verification

Spectrometer analysis can be used to verify carbon steel chemical composition.

Dimensional Inspection

CMM, gauges and conventional measuring equipment are used for critical dimensions and machined features.

Hardness Testing

Hardness can be checked when heat treatment or mechanical property requirements are specified.

Visual & Final Inspection

Casting surfaces, machining quality and key drawing dimensions are inspected before shipment.

Applications

Typical Applications

Custom carbon steel cast brackets can be used in industrial and hardware assemblies that require integrated mounting, connection or supporting features. Final geometry and material specifications are produced according to the customer's actual application.
