Engineering Plastics for Robotics & Automation: Lighter, Quieter, ESD-Safe

ESD Control in Electronics Assembly

Any robot touching semiconductors or PCBAs needs static-dissipative components — typically surface resistance between 10⁶ and 10⁹ Ω per IEC 61340-5-1. ESD POM and ESD PEEK provide stable, low-outgassing dissipation without humidity dependence. See our ESD Plastic Testing Standards guide for the details.

Machining Fixtures and End-Effectors

Custom grippers, jigs, and fixture pads are almost always machined from stock. POM-C is the workhorse for precision fixtures; PEEK serves hot zones and cleanrooms; UHMW-PE pads absorb impact without marring product. NAGOMER machines complete end-effector kits to drawings with full traceability.

Lifecycle and Total Cost Benefits

Plastic components usually cost more per piece than the metal equivalent — and still win on total cost. The savings accumulate across the whole lifecycle of the machine:

· No lubrication — grease supplies, lubrication schedules, and food-grade lubricant audits disappear

· Longer service intervals — wear parts such as guide strips and bushings often outlast metal counterparts several times over

· Lower energy draw — lighter arms and lower-friction joints reduce motor power and heat build-up

· Less noise — plastic gear trains and damping pads cut workplace noise without extra enclosures

· Fast spares — machined-from-stock replacements arrive in days, not the weeks a cast metal part needs

For electronics assembly lines, add the value of avoided ESD damage: a single saved wafer or PCB batch can pay for an entire set of ESD-safe end-effector components. Evaluating materials on purchase price alone systematically undercounts these benefits — evaluate on cost per year of reliable production instead.
