Needle Detectors for Garment and Textile Manufacturing: How to Prevent Broken Needles from Reaching Consumers
Learn how needle detection supports garment and textile inspection, helping manufacturers address the risk of broken needles in finished products.
Pipeline Metal Separators: How to Remove Metal Contaminants from Bulk Materials Before They Reach Your Equipment
What types of metals can a pipeline metal separator detect? Pipeline metal separators detect ferrous metals (iron, steel), non-ferrous metals (copper, aluminum, brass, lead), and stainless steel—including difficult grades like 304 and 316. Can a pipeline metal separator handle dusty or high-temperature materials? Yes. JINDUN pipeline metal separators feature sealed sensors and robust construction for […]
Weight Sorting Machines for Food and Agricultural Products: Multi-Level Grading Solutions
What is the difference between a checkweigher and a weight sorter? A checkweigher is designed to verify that products fall within an acceptable weight range and reject off-spec items. A weight sorter (or grading machine) goes a step further—it classifies products into multiple weight categories (e.g., small, medium, large) for different markets or price tiers. JINDUN offers both solutions […]
Aluminum Foil Metal Detector vs Standard: 5 Critical Differences
Table of Contents What is the difference between a foil detector and a standard detector? A standard metal detector uses basic electromagnetic field detection, which works well for non-foil products but fails with aluminum packaging because the foil creates overwhelming interference. A foil metal detector, by contrast, uses advanced digital signal processing, phase suppression technology, […]
X-Ray Foreign Body Detection Machine: Beyond Metal Detection for Comprehensive Quality Assurance
Can X-ray systems replace metal detectors? No. X-ray and metal detection serve different roles. Metal detectors are highly effective for ferrous and non-ferrous metal contaminants and remain essential for regulatory compliance in many applications. X-ray adds comprehensive foreign body detection—including glass, stone, bone, and dense plastics—plus quality checks like fill level and seal integrity. Many […]

How to Choose a Food Metal Detector: 7 Essential Factors
Table of Contents What sizes of metal can a food metal detector detect? Detection size depends on metal type, product effect, and aperture size. Typical practical sensitivity ranges are: ferrous metals 0.8–2.0 mm, non-ferrous metals 1.5–3.0 mm, and stainless steel 2.0–5.0 mm. Always validate sensitivity on your actual products at intended line speeds before purchasing. […]
