X-Ray Foreign Object Detection Machine: Buyer's Guide

When to Upgrade from Optical to X-Ray

If you are deciding between an optical vision system and X-ray for your line, the question is simple: can light reach the defect? Optical machines like the HZXX-JC01 single-table model (/posts/hzxx-jc01-single-table-inspection-machine) inspect surfaces, edges and dimensions. X-ray is for what is sealed inside - foreign objects in canned food products, contaminants inside earphone pad assemblies, internal defects in IC chips. This page is the buyer's decision guide; configuration facts live on the X-ray machine page (/products/xray-foreign-object-detection-machine).

What X-Ray Inspection Covers

From the Shengyi New Material (Huzhou) Co., Ltd. brochure, the standard application groups are canned products, earphone pads and IC chips. For industrial parts such as oil seals, bearings and gears, and for packaging containers such as bottles and bottle caps, the machine is tailored - a non-standard configuration built around your product geometry and detection difficulty.

Foreign Objects: Define What You Must Catch

Every X-ray project starts with a foreign-object definition: the object types you must catch - for example metal, glass, stone or bone - and the minimum size of each. These types differ in detection difficulty, and the smallest detectable size depends on your product's material and density, so it is confirmed on real samples rather than promised from a table. If you are still formalizing your criteria, how to define OK/NG defect criteria (/posts/defining-defects-ai-visual-inspection) applies to foreign objects too.

Optical vs X-Ray: A Working Comparison

• Surface scratch, chip, dimension error: optical inspection is the right tool.

• Foreign body sealed inside a product: X-ray.

• Internal structure or fill-level check on opaque packaging: X-ray.

• High-speed surface sorting of open parts: optical.

When both apply - surface quality plus internal contamination - the two technologies usually sit on different stations rather than competing for the same job.

Tailored vs Standard: What to Expect

X-ray machines are mostly tailored. Components such as the generator, detector and shielding are matched to your part geometry and the smallest foreign object you must catch, so the quotation process starts with samples: we confirm feasibility on your products and then propose the machine, rather than picking a stock model off a list. If you are budgeting this alongside other inspection equipment, see vision inspection machine cost: 7 price factors (/posts/vision-inspection-machine-cost-7-price-factors). For the order-to-installation process in general, see buying an inspection machine from China (/posts/buying-inspection-machine-from-china-what-to-expect).

Radiation Safety and Installation

X-ray equipment must be configured with radiation safety and shielding per installation and market. Confirm the applicable local regulations for your plant with your local authority, then share them with the factory so shielding and operator safety are part of the same scope. Prepare the installation site details - space, utilities and access - early, because they affect the shielding design.

When Not to Choose This Machine

Not the tool for surface-only defects - a standard optical machine does that at lower complexity. If your products have no internal volume that could hide foreign objects, X-ray adds cost without adding detection capability. Parts with very high density variations need a feasibility check first.

Frequently Asked Questions

Which products are covered? Canned products, earphone pads and IC chips, plus tailored non-standard machines for oil seals, bearings, gears, bottles and caps.

Can it inspect food or beverage products? Canned food products are one of the standard application groups in the brochure; feasibility is confirmed on your samples.

Which foreign objects can it detect? That depends on what you must catch - for example metal, glass, stone or bone - and the minimum size of each, confirmed on your product samples rather than promised from a table.

When should I choose X-ray? When surface optical inspection cannot reach inside the product, or when internal contamination is the requirement.

Is it a standard machine? Mostly tailored - each machine is configured around the product geometry and detection difficulty.

What to Prepare Before You Ask for a Quote

Prepare: samples of the products to inspect, the foreign object types and minimum sizes you must catch, your throughput target, and the installation site details for shielding planning.
