The Orthopedic Implant Component conforms to ASTM F75 CoCrMo. As a hygienic casting, it is defined by the dimensions in the table below; this page also covers the alloy options, the surface finish and the machining allowance.
What Is a Orthopedic Implant Component?
The Orthopedic Implant Component is a hygienic casting. It is selected by overall length together with the wall thickness and the hole or port geometry shown in the table below, and is supplied in a range of alloys and surface conditions to suit the service.
How This Part Is Cast
A wax pattern is injected into a metal die, assembled onto a runner system, dipped repeatedly in ceramic slurry to build a shell, dewaxed, fired and poured. The result is a casting that reproduces the pattern closely enough that most surfaces need no machining at all, which is what makes the process worth its tooling cost at production quantity.
Alloy Options
The catalog specification calls for CoCrMo (ASTM F75). This part is supplied in CoCrMo (ASTM F75), CF8M, CF3M, CF8, CB7Cu-1 (17-4 PH) and Ti-6Al-4V (Grade 5). The alloy drives both price and lead time more than any other choice on the RFQ, so state it if your drawing calls one out — and if it does not, describe the service (the medium, the temperature and the pressure) and we will propose one.
Tolerances, Finish & Machining
As-cast dimensions are held to ISO 8062-3 DCTG 6-8 on a silica sol shell, which is roughly ±0.3 mm on a 50 mm feature and widens with size. As-cast surface finish is typically Ra 3.2-6.3 µm. A machining allowance of 1.5-3 mm is added to the faces called out on the drawing; every other surface is supplied as-cast. For hygienic service the wetted surfaces are ground and polished to Ra 0.8 µm or better and passivated, since an as-cast surface will not pass a hygienic-design audit. State the tolerance grade and the finish you need on the RFQ — both change the price, and a tolerance nobody asked for is the most common avoidable cost on a casting.
Inspection & Testing
Chemical composition by spectrometer on every heat, with the certificate supplied against the specified grade.
Dimensional inspection against the drawing, with a first-article report on new tooling.
Surface roughness measurement on the wetted surfaces and a passivation certificate to ASTM A967.
The Orthopedic Implant Component is made to order. Pricing starts from approximately US$68.00 per piece for the smallest listed size in CoCrMo (ASTM F75) at production quantity; the final figure depends on pour weight, alloy, machining scope, surface finish and order quantity, and tooling is a separate one-time charge.

Inside the plant
Manufactured in our own plant
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Tooling & wax injection
An aluminum die is cut from your drawing or 3D model, and wax is injected into it under pressure. Everything downstream is a copy of this pattern, so the die is where the tolerance is actually decided — not on the shop floor afterwards.
First-article dimensional report on every new die before production wax is run.
02
Tree assembly & gating
Patterns are welded onto a wax runner to form a tree. How they are gated is not cosmetic: the gate positions decide which sections solidify last, and a heavy section fed from the wrong direction is where shrinkage porosity comes from.
Gating reviewed against the part's heaviest section before the first tree is built.
03
Ceramic shell building
The tree is dipped in ceramic slurry and stuccoed with refractory grain, six to eight times, drying between coats. The face coat is what the casting surface copies, which is why a silica sol face gives Ra 3.2-6.3 µm where a water-glass shell gives a coarser one.
Slurry viscosity and drying room temperature and humidity logged per coat.
04
Dewaxing
A steam autoclave melts the wax out fast, so that the wax — which expands more than the ceramic does — leaves before it can split the shell. Recovered wax is filtered and reused for gating rather than for patterns.
Every shell inspected for cracks after dewax; a cracked shell is scrapped, not patched.

Frequently Asked Questions
What is the controlling specification for the Orthopedic Implant Component?
The Orthopedic Implant Component is cast to ASTM F75 CoCrMo. The dimensions on this page follow that specification, and the material certificate supplied with the order is issued against it.
Which sizes of the Orthopedic Implant Component does lostwaxcasting.net supply?
The table on this page lists 5 sizes for the Orthopedic Implant Component by overall length, from 40 mm to 115 mm. Sizes outside the table are quoted on request — investment casting is tooled per part, so a new size is a new pattern die rather than a stock item.
Which alloys is the Orthopedic Implant Component cast in?
The catalog specification calls for CoCrMo (ASTM F75). The Orthopedic Implant Component is supplied in CoCrMo (ASTM F75), CF8M, CF3M, CF8, CB7Cu-1 (17-4 PH) and Ti-6Al-4V (Grade 5). The alloy drives both the price and the lead time more than any other choice on the RFQ, so state it if your drawing calls one out — and if it does not, describe the service (the medium, the temperature and the pressure) and we will propose one.
What wall thickness does the Orthopedic Implant Component have?
The listed sizes run from 3.5 mm to 10 mm of nominal wall. Investment casting will hold a section down to about 1.5 mm in the silica sol shell used here — 0.6 mm on a small isolated feature — and the thin end of that range is a shell-filling question rather than a strength one. A section much heavier than the surrounding wall is the more common problem: it solidifies last and shrinks, so it is fed or cored rather than left solid.
What surface finish does the Orthopedic Implant Component have for hygienic service?
The wetted surfaces of the Orthopedic Implant Component are ground and polished to Ra 0.8 µm or better and passivated to ASTM A967. An as-cast surface at Ra 3.2-6.3 µm will not pass a hygienic-design audit, so the finish is specified rather than assumed.
How do I request a quotation?
Set the configuration on the technical drawing above — size, alloy, finish — and click "Request this configuration". The values carry into the quote form below it. Attach a drawing or a STEP file if you have one; it is the fastest route to a firm price, and it lets us flag any castability issue before you commit to tooling.
Guides for the Orthopedic Implant Component
Each grade changes the price, the weight and what the part survives, so there is a page per grade for this part: CoCrMo (ASTM F75) (the catalog grade), CF3M (low carbon, for welded assemblies), CF8M (the chloride-resistant default), CF8 (cheaper, where chlorides are absent), CB7Cu-1 (17-4 PH) (age-hardened, high strength) and Ti-6Al-4V (Grade 5) (half the density, seawater immune).
How it is shelled decides the tolerance and the surface you get, and the tolerance band is worked out against this part's own dimensions on each: Vacuum Investment Casting (DCTG 5 – 7, Ra 3.2 – 6.3 µm).
If the question is still whether a casting is the right way to make this part at all, the Orthopedic Implant Component application guide covers where it is used, what has to be decided before a price exists, and where investment casting is the wrong answer.
