SIKORA’s optical inspection system ensures rPET quality
SIKORA’s PURITY CONCEPT V system for optical inspection and analysis is used at Hiroyuki Industries (M) Sdn Bhd, a subsidiary of Japan’s Hiroyuki Co., Ltd. at Malaysia specializes at recycled PET (rPET) resin and high-quality packaging solutions for food and beverage industry.

The optical inspection system is integrated into Hiroyuki Industries’ quality control laboratory. It inspects rPET samples before shipment and automatically detects visual defects such as black specks and discolorations on the pellets, and other contaminants as small as 50 micrometers.
By replacing manual inspection processes, the PURITY CONCEPT V significantly increases accuracy and efficiency in quality control.
“With the PURITY CONCEPT V, we have significantly improved our ability to detect visual contaminants of the pellets. This not only enhances product quality but also boosts confidence in our material among our customers,” said Chan Shuang, QA Assistant Manager at Hiroyuki.
The use of the PURITY CONCEPT V has led to measurable improvements in product consistency. Defects are detected earlier, allowing for immediate corrective action and reducing the number of non-conforming batches.
Each inspection is recorded and archived, creating a reliable data trail that supports traceability, customer assurance, and regulatory audits. This data includes the number and size of defects, providing the team with valuable insights for ongoing process optimization.
Looking ahead, Hiroyuki aims to evolve into a comprehensive hub for rPET resin, preforms, and bottle production within its region.
