Downstream process integration

• Material is dried below 0.10% moisture before dosing to injection molding lines. Precise dosing by gravimetric feeder ensures consistent conductive path formation. Typical shot weights range from 15 g for micro-housings to over 1 kg for server chassis partitions. Post-molding, parts undergo surface resistance testing to meet customer ESD targets.

Final product types

• Modular electronic instrument cases

2. Industrial Automation Components and Machine Guards

In automation equipment, the raw material is integrated where high-strength composite plastics hold tolerances during continuous motion and exposure to oils or cleaning fluids. Its built-in ESD performance allows safe use in sensitive industrial environments such as pick-and-place robotics, drive systems, and cleanroom machine covers, preventing electrostatic discharge even when friction accumulates static on machine surfaces.

Industry compliance standards

• EN ISO 14120 (Safety of machinery—Guards—General requirements for the design and construction of fixed and movable guards)

• Directive 2006/42/EC (Machinery Directive—CE marking requirements)

Typical usage ratio

• Used at 90–100% as structural resin in injection molding. UV stabilizer masterbatch added up to 2% if intended for high UV or artificial light environments. Fillers up to 4% may be incorporated for specific mechanical damping properties on customer request.

Downstream process integration

• Compounded granulate loaded into high-precision injection presses with hot-runner tooling for tight-tolerance guard geometries. Robotic demolding and post-cool trimming ensure repeatable dimension and ESD surface function. QC includes tensile and flexural modulus checks at batch release.

Final product types

• Robotic arm covers with ESD control
• Mechanism guards for automated conveyor lines
• Sensor light barriers and shields
• Static-dissipative control panel covers

3. Automotive Fuel System and EV Battery Module Parts

Our PA12-GF30 ESD grade is adopted in automotive manufacturing for fuel system and electronic vehicle (EV) battery module covers, spacers, and sensor housings. Its chemical resistance against fuels, additives, and coolants, plus dimensional stability after thermal cycling, make it suitable for hybrid and EV drivetrain components vulnerable to static build-up and surface tracking failures.

Industry compliance standards

• IEC 61000-4-2 (Electrostatic discharge immunity test)
• UNECE Regulation No. 100 (EV safety, Part II—Protection against electrical failures including ESD)
• IATF 16949:2016 (Automotive quality management system)

Typical usage ratio

• Utilized as the main component at 95–100% in direct injection molding or for hybrid composite structures. Additional coupling agents or impact modifiers up to 5% depend on OEM tolerance to vibration and thermal requirements in end-assembly.

Downstream process integration

• Feeds into automated molding cells where inline gravimetric blend ratios are fine-tuned for shot consistency. Parts undergo gamma or UV aging to verify property retention. Post-assembly, final check includes ESD discharge decay and electric insulation resistance per OEM test protocols.

Final product types

• EV lithium-ion battery module shrouds
