X-ray Inspection of Insert Molding Parts

Release: 2023-03-20, M.P.

Insert molding is a method of integrally molding metal parts such as terminals by using resin or rubber. Insert molded products may look normal from the outside, but metal-to-metal contact may cause a short circuit, or voids in the resin may weaken the strength, resulting in defective products. Therefore, it is necessary to observe the inside of the object by X-ray image. Insert molded products are used in many electronic devices such as terminals, terminal blocks, connectors, switches, gears, and cases.

Such observations need high X-ray tube voltage to view the detailed metals and a high-resolution camera to inspect the shape and voids in the resin part.

The benchtop X-ray inspection system precision μB4600 has options in terms of X-ray tube voltage and X-ray camera to meet your needs. For customers who frequently observe metals, a high-vision model with an optional X-ray tube voltage of 100 kV is available. An advanced option, models employing the tube voltage 60 kV and 3-megapixel, are provided to inspect a wider area of resin parts.

The X-ray CT-compatible inspection system, precisionμB4500, features a new artifact reduction function that enables observation of hidden areas from noise.
