Investment Casting for Medical and Orthopedic Parts

Medical investment casting is a preferred way to make small, complex metal parts for medical and orthopedic equipment. BRK Metal casts orthopedic parts, especially external fixation parts, to customer drawings.

Investment Casting for Orthopedic Parts

External fixator parts must be complex in shape, strong and dimensionally consistent. Investment casting produces these forms as one piece, which reduces machining and assembly.

Why Investment Casting for Medical Parts?

• Small, detailed parts: Thin sections and complex forms can be cast as one piece.
• Smooth surface: The ceramic shell makes later surface work easier.
• Repeatable dimensions: Parts stay consistent in series production.
• Less machining: Less material is lost from costly alloys.

Material Selection

Corrosion resistance and cleanability matter most in medical equipment, so stainless steel is widely used. Aluminum can suit parts where weight matters. Our 304 vs 316 guide helps with grade selection.

Tolerances and Quality

We work to VDG P690 and can meet D3, its tightest class. Requirements specific to medical device regulations are reviewed against your drawing and specification at the quotation stage.

Design Points for Medical Devices Parts

• State whether the part is used outside the body and which standards apply.
• Define surface roughness requirements on the drawing.
• Clarify cleaning and finishing steps at the quotation stage.

Frequently Asked Questions

Which materials are used for Medical Devices parts?

316 and 304 stainless steels are our main options. The right grade depends on the application.

Which medical parts do you cast?

We cast orthopaedic parts, especially for external use outside the body.

What part sizes and tolerances can you cast?

We cast parts from 1 g to 25 kg and meet tolerances up to VDG P690 D3.

What do you need for a quotation?

A drawing or 3D model, the material and the annual quantity. Price and minimum order quantity depend on the part.
