Materials for CNC machining.
Selected for your part.

Rigid PVC, CPVC and flexible PVC are different specifications. Define the required type, chemical exposure and stock form before reviewing a machined component.

PEI components need the resin grade and operating conditions specified. Review electrical, thermal and dimensional requirements before choosing stock and a manufacturing route.

PTFE parts require the grade, filler and service conditions to be clear. Review sealing, load, temperature and fit requirements together because deformation can affect performance.

PPS parts require a specified resin and filler package. Review temperature, chemicals, loading and the details of the mating components before confirming the material.

PPSU components need their resin grade and service cycle defined. Specify cleaning or sterilisation conditions, appearance and documentation where the application requires them.

Polypropylene parts need the resin grade and chemical service conditions defined. Review stiffness, wall geometry and assembly requirements before selecting the stock and process.

Polycarbonate is considered for tough plastic components and transparent parts. Define the grade, appearance, contact chemicals and assembly conditions before machining.

PEEK selection depends on the resin grade, filler, load, temperature and chemical exposure. State those requirements with the drawing so stock selection and machining can be reviewed together.

Acetal parts are often considered for low-friction mechanical components. Specify POM-H or POM-C, the resin grade and any filler so the material on the quote matches the drawing.

FR-4 is a glass-epoxy laminate used where electrical insulation and a rigid sheet form are needed. Specify laminate grade, thickness and any electrical or flame-rating requirements.

G-10 is a glass-epoxy laminate used for insulating and structural components. Define laminate specification, thickness, edge condition and the dimensions that matter in service.

Acrylic (PMMA) is considered when transparency and a rigid plastic form matter. Specify optical surfaces, edge quality and assembly stresses before selecting the machining and polishing route.

ABS is a candidate for rigid prototype housings and functional plastic components. Match the stock grade to the environment, appearance and dimensional requirements of the part.

Polyethylene covers materials with different density and wear behaviour. Specify the PE grade and working environment, then review how flexibility affects the required geometry and fits.

Nylon parts need the grade, filler and moisture condition defined. Review fits and inspection conditions together when the component must hold size through changes in humidity.

For loaded, wear-resistant or hardened components, define the steel grade and final condition before machining. Heat treatment, distortion and final inspection need to be planned together.

Stainless steel selection starts with corrosion exposure, strength and the features to machine. Specify the grade and condition so the manufacturing route matches the service environment.

Cast iron components need the iron grade and casting condition defined before machining. Identify datum surfaces, stock allowance and the features to inspect on the finished part.

For conductive components, specify the copper grade, material condition and contact surfaces. Review burr control, handling and any plating requirements against the drawing.

Titanium parts need a clear grade, stock specification and inspection plan. Review the geometry, material condition and surface requirements together before committing to production.

Brass is often considered for turned fittings, connectors and small precision components. Specify the alloy and any restrictions on lead content or end use before material is sourced.

Aluminum is a starting point for lightweight housings, brackets and fixtures. Select the alloy, temper and surface finish together, then review the drawing for machining and inspection.
