Products of the Plastics industry are diverse and increasingly used in many fields and industries. In the consumer sector, plastic products are used for packaging of all kinds, household plastic items, stationery, toys, etc. In other economic sectors, plastic products are also increasingly used; especially in some industries, plastic has also become an alternative material for traditional materials, such as in construction, electricity - electronics, etc.

Non-destructive testing in the plastics industry

Plastic is the basic ingredient that makes many products. Many manufacturers order parts and components from plastic companies that must meet specific guidelines for factors such as thickness, roughness, and structural integrity. Plastic manufacturers rely on non-destructive testing to measure properties critical to being able to meet customer needs.

HDPE pipe weld inspection

High-density plastic (HDPE) pipes have been used to replace steel pipes in the petrochemical, energy and mining industries due to their corrosion and erosion properties. More recently, HDPE has also been used in nuclear power plants in applications involving chilled water to maintain safety. Nuclear applications require safety guarantees at the connections. Ultrasonic time-of-flight diffraction (TOFD) is commonly used for structural integrity of these thermobaric welds.

The PV-200 system is based on two ultrasonic techniques, Time of Flight Diffraction (TOFD) and Phased. While TOFD is a fast, relatively efficient technique that detects defects of any orientation and shape and is capable of accurately sizing defects, TOFD has inherent limitations in certain areas. near the top and bottom of the material. The Phased Array perfectly complements these limitations and also provides other information that makes the assessment of defects much simpler and more accurate. The PV-200 solution is often used to replace traditional radiography or ultrasound.

RoHS screening in plastic manufacturing process

For homogenous inputs or complex products, manufacturers work with suppliers to manage compliance and have measures in place to regularly test incoming materials.

Using XRF spectroscopy as a screening tool is an effective and cost-effective way to ensure that products are RoHS compliant. In addition to purchasing from RoHS-compliant sources and tracking suppliers' Certificates of Compliance, the IEC guidance recommends using XRF screening as a practical and critical verification step towards ensuring compliance. .

  • Homogeneous material checks can be performed with simple and fast XRF equipment.
  • Double-check supplier claims using regular screening.
  • Performing on XRF assays is less expensive than other chemical analyses.
