Custom Investment-Cast Stainless Hinges and Clamp Bodies
You can source stainless cast hinges or clamp bodies from Relia with their moving and mounting interfaces defined separately. We review the pivot geometry, pin or hardware scope and visible finish from your drawing. The sample checks the relationships needed for the intended mechanism, while load or cycle-life validation remains a specific requirement rather than an inference from polished appearance.

The Supplied Body and Companion Hardware Stay Separate
Relia treats the cast body, pivot and companion hardware as identifiable supply items. A hinge leaf's fixing face and pivot axis have different jobs, while a clamp body may add an opening or seating contact. We connect the specified machining and finish with those features so the order states what the assembled mechanism needs and what each supplied component includes.
Individual dimensions, assembled movement and appearance approval have separate acceptance bases. Use the named companion parts for the sample check.
Pivot and Clamping Contacts Define the Functional Shape
Start with the working motion. A hinge depends on a pivot axis and clearance; a clamp depends on contact position and how the parts close. Mark those relationships on the assembly view so the manufacturing and inspection plan protects the movement your design needs.

Lost-Wax Forming Establishes the Body
Lost-wax forming establishes the body shape before cleanup and finishing. Slender arms, knuckles and visible faces influence where pattern features and feed contacts can be placed. We discuss those locations before tooling release so necessary cleanup is not left to alter a critical contact later.
Relate the Pivot Axis to the Mounting and Axial Contacts
Casting forms the leaf or clamp body, while specified machining establishes the pin bore, axial faces and fixing references that control movement. A correct bore diameter alone does not set the clearance between two leaves or align the pivot with the mounting face. Define the component limits and the assembled relationship separately.
Relia reviews the setup and sequence around those references. Later polishing or coating must preserve the pivot entrances, edges and fitting surfaces rather than round them indiscriminately. Agree which dimensions are checked on individual bodies and which fit or movement checks are performed on an assembly, with the pin and other hardware scope stated explicitly.

Finish Choices Preserve Fit and Appearance
Surface finishing should preserve the working fit. Divide visible faces, sliding or clamping contacts and protected bores on the drawing. An agreed visual sample helps communicate appearance, while measured dimensions and roughness address the surfaces that carry functional requirements.
Material and Service Loads Have Their Own Requirements
Specify the material and delivered condition along with the service requirements. If the project needs load or cycle validation, define the assembly, conditions and acceptance method. A stainless casting photograph does not establish a safe working load or movement life for a complete mechanism.

Assembly Samples Test the Defined Movement
Check samples with the intended companion parts and a recorded revision. Keep dimensional results, appearance approval and movement feedback distinct so each has a clear acceptance basis. Buyer approval of the sample package then provides a practical reference for the repeat order.

Part Identity Carries into Repeat Orders
Part identity matters when similar castings form a pair or share an assembly. Keep drawing numbers, handedness, hardware quantities and packaging identification aligned. The reference products illustrate different hinge and clamp forms; they do not define a universal kit.

Send Your Hardware and Mating-Part Details
Send the body and mating-part drawings, material requirement and quantity. Include an assembly view, motion clearance and any finish sample or validation requirement. We can then review the body, machining and hardware boundaries as one understandable enquiry.
