100+ materials, across every process we run

Material selection guidance is included with every quote. This page covers what each material is generally used for so you can shortlist before you talk to us. Lead time and grade/color availability are confirmed per order.

CNC Machining

Metals & engineering plastics

Applied after machining, before the part ships. Finishing for the other capabilities on this page (applicable materials, color range, which options can combine) is confirmed per order — it isn't necessarily the same list as CNC's.

Injection Molding

Materials

Secondary processes available on molded parts. Applicable materials and options confirmed per order.

ProcessDescriptionBenefits
Painting and Coating
Painting and CoatingImproves appearance, UV resistance, and adds EMI shielding where required.
  • Wide color and finish range beyond molded-in color
  • Adds UV and weather resistance for outdoor parts
  • Conductive coatings add EMI/RFI shielding
Plating
PlatingMetallic layer applied to plastic parts for conductivity, corrosion resistance, or a premium finish.
  • True metallic appearance and feel at a fraction of the weight and cost of machined metal
  • Adds conductivity or EMI shielding
  • Improves surface hardness and wear resistance
Pad Printing / Screen Printing
Pad Printing / Screen PrintingApplies logos, text, or graphics to a molded surface.
  • Low cost per part at volume
  • Pad printing reaches complex 3D surfaces
  • Screen printing gives higher opacity and color saturation
Laser Engraving
Laser EngravingPermanent marking for branding, serial numbers, and barcodes.
  • Permanent and abrasion-resistant, won't peel like ink
  • No ink, solvents, or consumables
  • Precise enough for serial numbers and data matrix codes
In-Mold Labeling (IML)
In-Mold Labeling (IML)Pre-printed labels fused into the part during molding.
  • Graphic can't peel, scratch off, or be applied crooked
  • Supports full-color, photo-quality graphics
  • Eliminates a separate post-mold labeling step
Ultrasonic Welding
Ultrasonic WeldingFuses two plastic components with no adhesives or fasteners.
  • Strong, permanent bond in seconds, no cure time
  • Can produce airtight and watertight seals
  • No added fasteners or adhesive chemistry
Heat Staking (Inserts)
Heat Staking (Inserts)Embeds metal inserts like threaded bushings into plastic parts.
  • Metal-threaded fastening point, assembled/disassembled repeatedly
  • Stronger and more wear-resistant than molded plastic threads
Heat Staking (Joining)
Heat Staking (Joining)Softens plastic posts to form a permanent joint between parts.
  • Permanent joint formed in seconds
  • No fasteners, adhesives, or separate hardware
  • Consistent, repeatable results at volume
Drilling and Tapping
Drilling and TappingSecondary machining to hold tighter tolerance or add threads.
  • Tolerances and thread quality beyond what molding alone can hold
  • Avoids the tooling cost of molding tight features directly
Adhesive Bonding
Adhesive BondingJoins parts, including dissimilar materials, with industrial adhesives.
  • Works across dissimilar materials welding can't join
  • Distributes load across the full bonded area
  • Can seal a joint against moisture or air
Assembly
AssemblySnap-fit, fastening, welding, and bonding into a finished product.
  • Finished, ready-to-ship product, not loose components
  • One point of contact for the full build
Customized Testing, Reporting, and Design Validation
Customized Testing, Reporting, and Design ValidationAPQP, FAI, PPAP, Cpk, hardness, drop, leak, and tear testing on request.
  • Paper trail for regulated or quality-critical programs
  • Catches process drift before it's a field failure
  • Matches your program's documentation standard
Packaging and Labeling
Packaging and LabelingProtective packaging and product identification for distribution.
  • Parts arrive ready for shelf or line, not just the dock
  • Reduces the customer's repackaging or relabeling work
  • Barcoding and lot tracking support traceability
3D Printing

Materials

SLA, SLS, PolyJet, MJF, FDM, and DLS. Post-processing (sanding, vapor smoothing, dyeing) confirmed per order.

Urethane Casting

Materials

Surface finish selected per part. Secondary operations (pad printing, painting, threaded insert installation) confirmed per order.

FinishDescriptionBenefits
Matte
MatteSmooth, non-reflective surface, works on any hardness of cast part.
  • Hides minor surface imperfections better than a glossy finish
  • Doesn't show fingerprints or handling marks the way gloss does
  • Consistent across rigid and soft durometers
Glossy
GlossyShiny, reflective finish, used for a polished or sealed look.
  • Premium, finished appearance with no separate polishing step
  • Smooth gloss surface seals better on soft elastomer parts like gaskets
Light Texture (MT11010 Equivalent)
Light Texture (MT11010 Equivalent)Subtle sand-like texture, cosmetic finish or light grip.
  • Softens the look of a part compared to raw matte or gloss
  • Hides minor surface imperfections and parting lines
  • Adds a small amount of grip without feeling rough
Medium Texture (MT11020 Equivalent)
Medium Texture (MT11020 Equivalent)More pronounced graining, more visible surface interest.
  • More visually distinct than Light Texture, still reads as cosmetic
  • Hides tool marks and surface imperfections more effectively
Heavy Texture (MT11030 Equivalent)
Heavy Texture (MT11030 Equivalent)Deepest available texture, grip over cosmetics.
  • Adds functional, tactile grip, not just cosmetic texture
  • Hides parting lines and surface defects most effectively
