Automotive Wire Harness Full-Line Project

How KexLink delivered a one-stop upgrade package for a Tier-1 Chinese harness supplier — precision hardware, automation lines, in-line recycling, vehicle-grade compounds and auxiliary equipment — meeting IATF 16949 and EU environmental compliance.

Customer Profile

Tier-1 automotive wire harness supplier. Product portfolio covers new-energy high-voltage harnesses, charging-gun assemblies, battery-pack wiring and ICE-vehicle low-voltage harnesses. Products supply multiple vehicle OEMs and are exported in volume to Europe.

Project Goals

Reduce labor dependency and stabilize automotive-grade yield

Cut heavy waste loss during injection and extrusion

Consolidate fragmented multi-vendor sourcing

Pass overseas factory audits and carbon-footprint assessments

A Tier-1 Harness Supplier Going Global

02 · Business Challenges

Four Pain Points Holding Back the Plant

Challenge 01

We provide full-chain supporting services for cable manufac-turers, empowering the manufacturing sector to reduce costsand improve efficiency through intelligent technology.

Challenge 02

Massive sprues from charging-gun and connector injection, plus extrusion trim waste. Off-site third-party recycling brings high logistics costs; externally recycled material degrades and cannot be reused for automotive-grade parts.

Challenge 03

Hardware, automation machinery, plastic compounds and recycling systems were purchased from separate vendors, leading to inconsistent lead times, fragmented quality standards and high coordination overhead.

Challenge 04

Automotive cables demand oil-resistance and wide-range temperature tolerance. Imported specialty materials have long lead time and high cost. Conventional auxiliaries deliver poor temperature control, causing bubbles and dimensional drift.

Five Integrated Modules, One Delivery

Automotive-Grade Precision Conductive Hardware

Pain Point

Limited off-the-shelf hardware specs, long custom-mold lead time. Third-party hardware poorly fits stamping machines, causing crimp offset and insufficient pull-out force. VDE-certified parts for European orders were hard to source.

KexLink Solution

High-purity brass solid/hollow pins, integrated insert housings and bridge terminals. Leveraged 2000+ existing molds to shorten lead time. Hollow-pin design enables harness weight reduction. VDE-certified plug components meet European salt-spray and temperature tests, engineered for perfect compatibility with our stamping machines.

Full-Process Intelligent Automation Equipment

Pain Point

Manual processing damages shielding layers. Unstable crimp pull-force. No QR-code traceability. Paper-based records cannot support IATF 16949 audits. Slow mold changeover for charging-gun overmolding caused long downtime.

KexLink Solution

Full set of self-developed automation lines. Cable-processing units handle large cross-section high-voltage cables without shielding damage — one machine replaces 35 operators. Servo labelers enable QR-code traceability. Testers run continuity, insulation and hipot tests with archivable digital reports. Vertical, C-frame and double-slide injection machines connect to recycling units for closed-loop workflow.

In-Line Hot-Grinding & Pelletizing Closed-Loop System

Pain Point High logistics cost for off-site plastic scrap disposal. Outsourced recycled material fails automotive-grade requirements. Dust & odor from open grinding cannot pass overseas audits.

KexLink Solution On-site inline hot grinding & pelletizing recycles sprues and cable trims into usable pellets, with >95% recovery rate. Fully sealed design controls dust and odor, compliant with EU REACH and OEM green factory standards. 24/7 continuous operation supported.

Eco-Friendly Compounds for Automotive Harnesses

Pain Point Harsh operating environments for automotive wiring harnesses. Expensive imported materials with long lead times. Poor compatibility of third-party plastics causes precipitation and high defect rates. Export products need both RoHS and REACH compliance.

KexLink Solution Halogen-free TPU, TPE, EPDM & cross-linked polyolefin compounds for automotive cables. Custom grades for new-energy high-voltage harnesses and interior signal wires. All materials comply with RoHS & REACH, optimized for KexLink extrusion/injection machines. Recycled pellet blending lowers cost while retaining quality.

Injection Molding Machine & Auxiliary Equipment

Pain Point

Automotive plastics demand strict control over drying, mold temperature and cooling. Insufficient drying causes bubbles; temperature fluctuation brings dimensional drift. Conventional auxiliaries lack overload protection and tend to break down. Manual feeding is labor-intensive.

KexLink Solution

Vertical / double-slide injection machines paired with hopper dryers, autoloaders, mold-temperature controllers, industrial chillers and central feeding systems. Precise PID temperature control manages drying, mold temperature and cooling water. Multi-layer overload protection guarantees long-hour continuous operation. Optimized for automotive plastic molding conditions, reducing defects from bubbles, deformation and dimensional deviation.

Results After Commissioning

Labor & Quality

Manpower dropped significantly. Yield of high-voltage harnesses and charging-gun assemblies improved. Digital test records cleared IATF 16949 audits and overseas factory inspections.

Material Cost

On-site closed-loop recycling cut virgin plastic purchase volume and almost eliminated waste-disposal expenses. Equipment investment achieved expected payback period.

Simplified Supply Chain

Hardware, automation, recycling systems, compounds and auxiliaries delivered and supported by KexLink as a single source — drastically lowering multi-vendor coordination overhead.

Export Compliance

Eco-friendly materials plus enclosed recycling satisfy REACH, RoHS and carbon-footprint requirements. The customer secured more European new-energy harness orders.

“Previously we had to engage multiple vendors for harness-plant upgrading with heavy coordination workload. KexLink delivers hardware, machinery, recycling systems and plastic compounds as a full package with well-coordinated commissioning. They helped us stabilize automotive-grade yield while real-world plastic-waste recycling reduced production cost. Our European-project environmental audit requirements are fully satisfied. KexLink is our trusted one-stop supporting partner.”
