The CST-50 Impact Specimen Notch Projector is a specialized optical inspection tool essential for Charpy and Izod impact testing. It is primarily used to verify the precision of V-notch and U-notch profiles on metallic specimens before testing. Unitedtest Lyrictest

Technical Analysis & Core Functionality

* Purpose: Magnifies the notch area of a specimen by 50x to ensure compliance with strict geometric standards (e.g., radius, angle, depth). Upwelltest Impacttestingmachine

* Standards Compliance: Vital for labs adhering to ASTM E23, ISO 148, GB/T 229, and EN 10045. Unitedtest Upwelltest

* Key Specs: Features a 180mm or 200mm screen, high-intensity halogen light source (12V/100W), and a high-precision adjustable worktable. Lyrictest Alibaba

Market Trends & Industry Insights

1Manufacturing Cluster: Production is heavily concentrated in Jinan, China, which serves as the global hub for material testing equipment. Major established manufacturers include Liangong, Hensgrand (HSSD), and Kason.
2Product Integration: A growing trend toward bundled sales. Buyers increasingly source the CST-50 alongside electric broaching machines (for creating the notch) and low-temperature cooling chambers to establish a complete Charpy testing workflow. Unitedtest
3Technological Upgrades: While traditional models are purely optical, the market is shifting toward Digital Display versions that reduce human error and improve throughput in high-volume industrial labs. Unitedtest
4Pricing Landscape: Standard units typically range from $500 to $1,500 depending on the supplier and verification status, with highly specialized or digital models reaching higher price points.

Sourcing Recommendations

* Verified Factories: Prioritize suppliers with over 10 years of experience and ISO/CE certifications, such as Jinan Liangong or Jinan Kason, especially for export needs.

* Customization: Many suppliers offer dual-voltage (110V/220V) support and customized worktables to fit specific lab requirements.
