Utilize INTERTECH Injection Molding for High-Strength, Low-Friction Mechanical Components

When gears must run quietly for 10 million cycles or a sliding bushing must out-last metal—and do it at one-third the weight—INTERTECH’s precision injection-molding platform delivers. By combining advanced mold design, science-based processing, and a library of reinforced, self-lubricating polymers, INTERTECH produces parts that shrug off wear while holding micron-level tolerances. Below is a practical guide to leveraging INTERTECH for demanding mechanical applications in automation, e-mobility, and industrial equipment.

1 Material Formulations Engineered for Strength and Low Friction

Polymer Family	Typical Additives	Key Performance Wins	Ideal Components
POM / Acetal	PTFE, silicone, graphite	Coefficient of friction ≤ 0.15; no stick-slip	Gears, worm wheels, sleeve bearings
Glass-Fiber PA 66	30–50 % GF + MOS₂	Tensile strength 200 MPa; surface PV > 0.8 MPa·m/s	Belt-tension rollers, pulley hubs
PEEK	Carbon fiber, PTFE, graphite	250 °C service temp; wear factor K ≤ 2×10⁻⁸	High-speed pump vanes, aerospace valve seats
LCP (Liquid Crystal Polymer)	30 % GF	Mold shrink ≤ 0.1 %; dry-run safe	Micro-gears, precision cams, connector sliders
TPU Over-mold on Nylon	Oil-resistant elastomer	Quiet cam followers, vibration damping	Sprocket idlers, linear-guide bumpers

INTERTECH keeps core grades in stock and can sample custom compound blends in ≤ 10 days.

2 INTERTECH Process Advantages at a Glance

Capability	How It Boosts Mechanical Performance
Scientific Molding – cavity-pressure sensors and DOE-locked windows	CpK ≥ 1.67 on tooth thickness; eliminates load-noise variation
Conformal-Cooling Inserts & BeCu Cores	15–30 % faster cycles; uniform crystalline morphology → consistent modulus
In-Mold Lubricant Dosing	PTFE micro-capsules infused at gate for even distribution; zero dry-lubricant streaks
Mold-Flow Fiber-Orientation Simulation	Aligns glass/carbon fibers along load path; raises fatigue life 40 %
Automated Vision & Torque Testing	100 % gear tooth-span measurement; rejects any part with out-of-spec startup torque

3 Design Guidance for Strong, Low-Wear Parts

Wall Thickness – Keep between 1.2 – 3 mm; taper ribs 50 % at root to minimize sink and maintain fiber alignment.
Draft – ≥ 0.5° on load flanks ensures scratch-free ejection while preserving flank geometry.
Fillet Radii – ≥ 0.25 mm where fibers turn; reduces notch factor and squeak under dry sliding.
Gate Location – Place opposite primary load face; promotes favorable fiber flow into tooth root.
Surface Texture – SPI B-1 (600 Grit) on flank lowers initial break-in noise yet maintains oil retention.

INTERTECH’s DFM team supplies Moldflow snapshots and draft-gate studies within 48 hours of RFQ.
