Frequently Asked Questions

Permanent marking is required for traceability, quality control, and compliance with international standards like EN 14024 (Europe) and ASTM E2181 (North America). Markings typically include batch numbers, production dates, manufacturer identification, and technical specifications. This ensures that every strip can be traced back to its production source, which is critical for warranty claims, quality audits, and building certification.

Standard thermal break strips are made of PA66 GF25 (Polyamide 66 reinforced with 25% glass fiber). Fiber laser marking is ideal for this material because it creates a permanent, high-contrast mark through molecular-level interaction without weakening the strip's structural integrity. Unlike ink printing or embossing, laser marking doesn't introduce chemical contaminants or physical stress points.

Yes, for several reasons:

• Permanence: Laser marks are UV-resistant, chemical-resistant, and won't fade or smudge
• Precision: Achieves 0.01mm accuracy, allowing detailed codes and logos
• Zero Consumables: No ink, solvents, or ribbons required
• Non-Contact: No physical stress on the PA66 strip structure
• Eco-Friendly: No chemical waste or disposal requirements

Single-side marking lasers one face of the thermal strip, which is sufficient for most standard applications. Double-side marking simultaneously marks both faces, which is required when strips will be installed in configurations where both sides are visible, or when dual-side traceability is mandated by local building codes. Double-side systems typically increase production efficiency by 30-40%.

This refers to the feeding mechanism:

• Single Traction: One motor drives the strip through the marking zone. Suitable for standard lengths and stable production lines.
• Double Traction: Two synchronized motors at entry and exit points ensure perfect tension control. Essential for longer strips, thinner profiles, or high-speed production where strip deformation must be prevented.

We use IPG fiber laser sources (industry standard for reliability and beam quality). The typical lifespan is 100,000+ hours of operation. Laser power options range from 20W to 50W depending on marking speed and depth requirements. The laser module is maintenance-free and doesn't require alignment or gas refills.

Yes. Our laser marking systems support vector graphics, raster images, QR codes, DataMatrix, Code 128, and custom logos. The control software allows easy import of design files and automatic batch number/date generation. Marking content can be updated instantly via USB or network connection without mechanical adjustments.

Yes. Every KINGVAN machine includes:

• Comprehensive operation manual and video tutorials
• Remote installation guidance via video call
• On-site training available for bulk orders (travel costs apply)
• 24/7 technical support via email, WeChat, or phone

We provide a 2-year warranty on all mechanical and electrical components, and a 3-year warranty on the IPG laser source. Warranty covers parts replacement and technical support. We maintain a spare parts inventory to ensure fast replacement (typically 3-5 business days worldwide via express shipping).

Standard models (Single Side Single Traction, Single Side Double Traction) are typically ready in 15-20 business days. Custom configurations or double-side systems require 25-30 business days. We offer expedited production for urgent orders. Shipping time depends on destination (typically 7-15 days by sea freight).

Yes, we ship to over 30 countries. All machines carry CE certification for European markets, and comply with international electrical safety standards. We provide full documentation including CE Declaration of Conformity, user manuals, and calibration certificates. Our team handles export documentation and can assist with local import requirements.
