Materials & Tolerances

Reference data for engineers specifying injection-molded parts. If your material is not listed, ask — we source specialty resins through certified distributors.

Common Injection Molding Resins

Resin	Key Properties	Typical Applications
ABS	Tough, good cosmetics, easy to process	Housings, enclosures, consumer products
PC	High impact, transparent grades, heat resistant	Lenses, safety covers, medical devices
PC+ABS	Impact + processability balance	Electronics housings, automotive interior
PP	Chemical resistant, living hinges, low cost	Caps, containers, clips
PA6 / PA66 (+GF)	Strong, wear resistant; GF grades add stiffness	Gears, structural parts, under-hood
POM	Low friction, high dimensional stability	Gears, sliders, fasteners
PMMA	Optical clarity, UV stable	Light guides, displays, lenses
TPU / TPE	Flexible, soft-touch, overmolding grades	Grips, seals, bumpers
PEEK	High temperature, chemically inert	Aerospace, medical, semiconductor

Tooling Tiers at a Glance

Tier	Mold Steel	Tool Life	T1 Lead Time	Best Volume
Rapid	Aluminum 7075	100–5,000 shots	10–15 days	Validation & pilot
Bridge	P20 / NAK80	50k–100k shots	15–25 days	Low-mid volume
Production	H13 / S136	1M+ shots	25–45 days	Mass production

General Tolerances

Process	Standard	Precision (on request)
Injection molding	±0.1 mm (per DIN 16742 / ISO 20457)	±0.05 mm on critical features
CNC machining (metals)	±0.05 mm	±0.01 mm
CNC machining (plastics)	±0.1 mm	±0.05 mm

Surface finishes: SPI A1–D3 and VDI 12–45 textures; MT/YS texture plaques available on request.
