Product Overview
This adjustable hinge features an integrated pivot body, cylindrical mounting section and multiple positioning features within a compact casting. Investment casting allows these functional geometries to be produced as a near-net-shape component while reducing the amount of machining required compared with manufacturing the entire part from solid material.
Carbon steel provides a practical combination of strength, toughness and cost efficiency, making it suitable for custom hardware components that require reliable mechanical performance.

Features
Complex hinge, pivot and mounting features can be formed within a single investment casting, reducing separate component assembly.
Critical holes, bores, positioning surfaces and mating features can be CNC machined to achieve the required dimensional accuracy.
Carbon steel offers good mechanical strength and toughness for hardware components subjected to repeated mechanical loading.
Dimensions, mounting interfaces, wall thicknesses and functional features can be manufactured according to customer drawings.
Manufacturing
The component is first produced by silica sol lost wax investment casting to form the main body, pivot section and external geometry. After casting, the parts undergo gate removal, surface cleaning and dimensional inspection before required machining operations are performed.
Depending on the drawing, machining may include:
Pivot holes and bores
Mounting holes
Hexagonal or positioning features
Mating surfaces
Slots and recesses
Local dimensional finishing
Combining investment casting with CNC machining helps retain complex cast geometry while maintaining tighter tolerances at functional interfaces.
Quality Control
For adjustable hinges and pivot components, dimensional consistency at mating and rotating features is important for assembly and functional movement. Inspection can be performed throughout casting and machining according to customer specifications.
Chemical composition can be verified according to the specified carbon steel grade.
Critical dimensions, hole positions and machined interfaces are checked against the approved drawing.
Bores, holes, positioning features and mating surfaces are inspected after CNC machining.
Cast surfaces are visually inspected for unacceptable defects before final packing.
Applications
Investment cast carbon steel hinges and pivot components can be customized for a variety of mechanical hardware applications where compact structure, strength and controlled movement are required.
Typical applications may include:
Adjustable hardware assemblies
Mechanical brackets and joints
Pivoting support mechanisms
Locking and positioning hardware
Industrial hardware assemblies
Structural connection components
All components are manufactured according to customer drawings rather than standard off-the-shelf dimensions.
The hinge combines curved surfaces, recessed features, mounting geometry and an integrated pivot structure. Investment casting can form these features close to the final geometry, helping reduce material waste and unnecessary machining.
For applications requiring tighter tolerances, only the functional areas need to be CNC machined after casting.
