Tier-1 New-Energy Harness Supplier
Customer Industry
Tier-1 new-energy automotive harness supplier, manufacturing high-voltage harnesses, charging-gun assemblies and battery-pack wiring harnesses for multiple domestic vehicle OEMs, with partial product exports to Europe.
Project Background
Large volumes of injection sprues and defective components were generated during charging-gun housing and connector production. The cable extrusion workshop produced substantial trim waste from high-voltage cable manufacturing. Previously all plastic waste was collected for off-site third-party recycling, resulting in high material loss, labor handling and disposal costs. Externally reprocessed pellets suffered performance degradation and could not be reused for automotive-grade parts. Overseas buyers enforced strict green-factory, REACH and carbon-footprint requirements, demanding on-site closed-loop waste treatment.
Focus Product: In-Line Hot-Grinding & Pelletizing Closed-Loop System
02 · Onsite Application Scenario
Deployed Beside Injection Machines & In the Extrusion Workshop
The recycling system was installed beside injection-molding machines and within the cable extrusion workshop. The injection side connects to multiple charging-gun and connector injection-molding machines, directly receiving charging-gun sprues and defective molded parts.
The extrusion side interfaces with high-voltage cable extrusion lines to process high-voltage-cable trim waste. Recycled pellets are conveyed through pipelines back to local injection and extrusion machines for production of charging-gun housings, connector insulators and high-voltage cable jackets.

What the Customer Gained
Lower Handling Cost
On-site waste treatment eliminated labor and warehouse costs for waste bagging, handling and outbound transportation. Overall waste-recovery rate reaches above 95%.
Material Reuse
Recycled pellets retain satisfactory material properties and can be proportionally reused for charging-gun housings, connector insulators and high-voltage cable jackets, greatly reducing virgin-resin procurement.
Cleaner Workshop
Fully enclosed grinding-pelletizing structure controls dust and odor, improving workshop environment and supporting successful on-site green-factory audits from overseas customers.
Audit-Ready Records
The system keeps complete recycling-cycle records available for OEM carbon-footprint and REACH supplier assessments.
“Charging-gun injection molding and high-voltage cable extrusion generate large quantities of plastic waste which previously had to be sent off-site for disposal with heavy material losses. After deploying KexLink’s in-line grinding & pelletizing closed-loop system, waste is recycled and re-pelletized inside our workshop. Qualified regrind pellets go straight back into production. We save substantial material costs while the enclosed design satisfies European customer green-factory audit requirements.”
