Where PC/ABS Is Used in North American Manufacturing

Flame-retardant PC/ABS for busbar covers, module lids, and cell carriers where impact, UL 94 V-0 at thin wall, and flow matter more than heat

Painted grille frames and larger one-piece grilles where heat from the radiator and impact at the front corners exceed ABS

Painted body-color scalps and caps in PC/ABS where the program paints the mirror to match the door

PC/ABS for larger roof spoilers with an integrated CHMSL and wiper motor where heat in the sun and stiffness over a wide span exceed ABS

Higher heat and stiffness for thin-wall, low-sink retainers on premium and hard-IP programs; costs more per part but tools smaller and paints without primer

Upper visible surfaces, bezels, and thin-wall lids where scratch resistance, gloss control, and paintability matter more than resin cost

Higher heat and impact for shifter bezels and vent surrounds that sit in the sun-loaded upper console

The rigid frame the keymat sits in is PC/ABS for the same reasons the housing is: it matches, it is already qualified, and it holds the flatness the keymat needs to seal against. The frame also carries the light guide features and the snap interface to the board.

PC/ABS balances the impact and heat resistance of PC with the flow and cost of ABS; flame-retardant grades hit UL 94 V-0 at 1.5 mm and paint or texture well.

A molded chassis wins when it can consolidate a dozen brackets, standoffs, guides, and cable retainers into one part with no fasteners. PC/ABS is the usual choice because it is already qualified in the housing and the two parts can share a resin, a color, and a yellow card, which halves the qualification work.

PC/ABS appears on large buttons and rockers that are cosmetic first and mechanical second, and where the return force comes from a separate elastomer or metal dome rather than from the actuator itself. It matches the bezel and it molds to a Class A surface; it will not survive as a bearing surface.

The workhorse of consumer electronics enclosures. PC/ABS carries enough polycarbonate to hit UL 94 V-0 at 1.5 mm and survive a drop test, and enough ABS to fill a thin-wall housing at a cycle time that supports consumer economics. It paints, textures, chrome-plates, and ultrasonically welds, and it does not require the tool temperatures straight PC does. A supplier arguing against it is arguing against the only resin in the taxonomy that does all six things at once.

A bezel is the most looked-at surface on the product and the one that has to hold its snap fit flat across a 300 mm span. PC/ABS gives the stiffness to resist bow, the impact resistance to survive a bench knock on a corner, and the surface to take a high-gloss or fine-texture finish straight from the tool. It is also the resin most likely to already carry the same yellow card as the housing it clips into, which avoids a second qualification.

A battery door is opened by hand, dropped, and left in a pocket, and it is cosmetic. PC/ABS survives the hinge and latch fatigue that pure ABS does not while matching the housing color and finish it sits in, which is the harder requirement: a door in a slightly different resin is a visible color mismatch under fluorescent light.

Molded rack bezels, filler panels, and handle sets appear where the part is cosmetic rather than structural and the tooling amortizes across a product family. V-0 is mandatory here because the part lives inside the fire enclosure of an equipment rack.

PC/ABS balances impact, paintability, and dimensional stability for mirror heads that live at the front corner of the cab

Painted PC/ABS grilles and surrounds where heat behind the grille and impact loads exceed what plated ABS holds

Injection-molded PC/ABS instrument panel substrates hold shape under dash-top solar load and give a paintable, textured surface at truck volumes

PC/ABS where the bezel is a thin, long, unsupported span, where a laundry room or a wall oven surround runs hotter than ABS allows, or where a snap-fit has to survive service disassembly

PC/ABS takes the covers, bezels, and knobs where flow into thin sections and a matte molded finish matter and the part is not the primary structure. It is also the easier resin to mold in the small volumes an endoscope program runs

PC/ABS gives V-0 at thin wall with better flow into a large, ribbed enclosure than straight PC, and it is the usual answer for the back shell, door, and internal chassis parts where the aesthetic and chemical demands are lower than the front bezel

PC/ABS in flame-retardant grades for the low-voltage compartment cover, the communicating-control enclosure, and the inverter cover on variable-speed equipment, where the part has to be thin, stiff, dimensionally stable, and V-0

PC/ABS is the volume pack enclosure and it wins on the combination nothing else covers at the price: a UL 94 V-0 flame-retardant grade, enough notched impact to survive being dropped from a ladder onto concrete at 20 degrees F, and a molded latch rail and terminal pocket that hold tolerance so the pack seats in every tool on the platform. This is the fastest growing part family in the industry

Flame-retardant PC/ABS is the indoor residential battery shell because it molds a large cosmetic part with a Class A surface, carries V-0 at 2 mm, and takes texture and color that survive a garage wall for a decade.

Flame-retardant PC/ABS carries the covers, wiring compartments and cosmetic shrouds that do not sit in the thermal path.
