Production

Own factory in Shanghai.

Maintec Technologie Co., Ltd. is our production site in Shanghai — not contract manufacturing at third parties, but our own factory with 15+ years of experience.

Soldering
Laser Soldering

Laser Soldering

Contamination-free solder joints with no flux residue. Reproducible to ±0.1mm. Ideal for medical applications (IVUS, endoscopy) and safety-critical vehicle wiring. Rare in mid-sized companies.

Crimping

Crimping Technology

Fully automatic crimp stations with integrated force-distance monitoring. Every crimp is checked against target values in real time. Pull-force testing per IPC/WHMA-A-620. Cross-sections from 0.13mm² to 95mm².

Laser

Laser Stripping

Non-contact stripping from 0.05mm² cross-section. No mechanical damage to individual strands — critical for fine wires in medical technology and sensors. Repeatability ±0.2mm.

Testing
100% Final Inspection

100% Final Inspection

Five-stage test process for every piece: continuity test, isolation resistance (>100MΩ), hipot test (up to 2.5kV), pull-force measurement, visual final check. Full documentation and traceability.

Assembly

Sub-assembly

Pre-assembly on customer-specific board layouts to 1:1 drawing. Defined cable-tie positions, corrugated tube segments, grommets and heat-shrink. Ready-to-install kits with labeled connectors.

Logistics

Warehouse & Shipping

Own 500m² warehouse at Lurgiallee in Frankfurt. JIT call-offs with 24-48h delivery time within Germany. Kanban-controlled re-production, ESD-compliant packaging, customer-specific labeling.

Machine Park

Our production technology.

Own machines in our factory in Shanghai — no outsourcing, no third-party production. Below is a selection of our machine park.

CO₂-Lötmaschine

CO₂ Soldering Machine

Precision soldering technology for contamination-free, reproducible joints. Ideal for medical technology and safety-critical applications.

Laser-Abisoliergerät

Laser Stripping Machine

Non-contact stripping from 0.05mm² cross-section. No mechanical damage to individual strands. Repeatability ±0.2mm.

Hot-Bar Bonding

Hot-Bar Bonding

Thermo-compression bonding for finest wires and flex foils. Reproducible to ±0.1mm.

Crimpautomat mit Drucküberwachung

Crimp Press with Pressure Monitoring

Integrated force-distance monitoring. Every crimp is checked against target values in real time — defects detected automatically.

Vollautomatische Abisolier- & Crimpmaschine

Fully automated stripping & crimping machine

Cutting to length, stripping and crimping on both ends in a single operation. For high volumes with consistent quality.

Crimpautomat

Crimping Machine

Semi-automatic crimping station for cross-sections from 0.13mm² to 95mm². Pull-force testing per IPC/WHMA-A-620.

Quality Testing
Quality Inspection

Five test methods. Zero compromise.

Every piece is tested — not by sampling, but at 100%. Our test equipment documents every measurement for full traceability.

Durchgangsprüfer (ATX-512)

Continuity Tester (ATX-512)

Aigtek ATX-512 Wiring Harness Tester. Automatic continuity and isolation testing for up to 512 test points simultaneously.

Auszugskraftprüfgerät
