Product Overview

The QR-HST-Z Multi-functional Disappearing Mold Coating Detector is a specialized instrument designed for lost foam casting technology. It accurately evaluates three key performance parameters of casting coatings:

1. Transport characteristics of EPS cracking products through coatings (adsorption performance)

2. High-temperature permeability of coatings

3. High-temperature strength of coating layers

By combining computer control, automated data processing, and realistic simulation capability, the QR-HST-Z ensures precise, reproducible, and reliable testing results.

Instrument Features

• Computer-controlled system – enables high automation and accurate data processing.

• Multi-property testing – one sample can be used to evaluate several critical coating parameters.

• User-friendly operation – intuitive software interface with Windows-based data collection and storage.

• Realistic simulation – coating is applied directly on the original foam pattern for accurate, production-like testing.

• National utility model patent – innovative design with proven reliability.

Advantages

• One machine, multiple functions – measures adsorption, high-temperature permeability, and coating strength with a single setup.

• Closer to production conditions – coating application simulates real processes, ensuring convincing and relevant data.

• Additional coating property testing – drip time, coating thickness, and suspension differences can be evaluated during operation.

• Powerful computer integration – microcontroller + Windows-based system ensures cost-effectiveness, strong anti-interference, easy operation, and flexible data management.

• High reproducibility and sensitivity – delivers reliable experimental results with excellent repeatability.
