Graphite Parts Made to Your Drawing

MetalsTek supplies drawing-based graphite components through manufacturing partners. We review the part geometry, suitable material, operating conditions and requested inspection package before quoting. Critical dimensions and performance requirements should be identified on the drawing; feasibility is confirmed for each project.

Typical Machined Components

Fixtures & Support Parts

Positioning fixtures, support blocks and mounting features specified for your equipment or thermal process.

Molds & Dies

Drawing-based molds, dies and tooling for forming, pressing or casting applications, subject to material and process review.

Rings, Bushings & Sleeves

Cylindrical parts with specified bores, grooves, shoulders or mating features; edge and wall details require review.

Plates, Profiles & Assemblies

Custom plates, nozzles, shaped components and multi-part assemblies with holes, slots, channels or mating features defined by the customer drawing. Fit and inspection requirements are reviewed for each project.

Select the Material Around the Part and Process

Graphite grade selection is project-specific. The most useful comparison is between the properties your component needs and its actual geometry and working environment. The Carbon & Graphite Materials hub holds the full Grade Performance reference table; the values there are not a universal finished-part guarantee.

Purity & Ash

State impurity limits, contact materials and any cleaning or contamination-control requirements.

Grain & Mechanical Needs

Identify thin sections, fine features, load-bearing faces and any required strength or surface condition.

Thermal & Electrical Conditions

Provide working atmosphere, temperatures, cycling and electrical requirements where applicable.

Geometry & Inspection

Mark critical dimensions, tolerances, surface finish and the records needed for acceptance.

Drawing Review, Partner Manufacturing & Inspection

01 · Review

Send a drawing or sample details. MetalsTek and its manufacturing partners review material options and machining feasibility.

02 · Confirm

Agree critical features, quantity, required documentation and any cleaning or packing needs before order placement.

03 · Inspect

Define the dimensions or material records to be checked. The inspection method and deliverables are confirmed for the specific order.

No single tolerance, maximum size, lead time or certificate applies to every graphite component. These details are confirmed against the selected grade, geometry and order requirements.

Frequently Asked Questions

Yes. Send a drawing, quantity and intended use. MetalsTek reviews material choice and machining feasibility with manufacturing partners before quotation.

Specify a required grade if it is already qualified for your process. Otherwise, provide purity, load, atmosphere and geometry requirements so suitable options can be reviewed. The Carbon Hub contains the full grade reference table.

There is no single tolerance for every graphite part. Mark critical dimensions on the drawing; achievable tolerances depend on grade, size, wall thickness and feature geometry.

State the required dimensional records, material data or other acceptance documents in the RFQ. Availability and inspection methods are confirmed for the specific order.

Graphite can oxidize in oxygen-containing atmospheres at elevated temperature. Provide the atmosphere, temperature and exposure cycle so suitability can be reviewed.
