Metal detectors

7 Machines

Metal detectors are essential product inspection machines that check for the absence of metal particles in packaged products, ensuring consumer safety and compliance with quality standards required in the pharmaceutical, nutraceutical, food, and cosmetic sectors. Makinate offers a wide selection of used metal detectors from leading manufacturers such as Loma, Safeline, and other specialized brands, providing reliable solutions for quality control in automated packaging lines.

Function of metal detectors in production lines

Metal detectors are part of product inspection machines and integrate seamlessly into packaging lines to ensure there is no metal contamination in finished products.... Their primary purpose is to verify product integrity and detect any metal particles that could contaminate the product, posing a risk to consumer safety and potentially causing costly product recalls for the company.

Applications in the pharmaceutical sector

At an industrial level, especially in the pharmaceutical sector, this technology is used to detect the presence of metals in medicines. These systems are developed to meet the strict standards of the pharmaceutical industry and ensure maximum product safety for patients.

Inspection of tablets, capsules, and powders

Metal detectors inspect and verify that there are no metal particles in tablets, capsules, and pharmaceutical powders. Naturally, metal detectors check tablets before they are packaged into bottles, blister packs, or sachets, intercepting any contamination during the production phase before reaching the final packaging.

Automatic rejection system

Metal detectors are equipped with a rejection system, typically using a pneumatic gate device, to eject non-compliant tablets or capsules. This automatic mechanism ensures that only products free of metal contamination continue down the packaging line, while defective products are separated and collected in dedicated containers.

Sensitivity adjustment

These machines allow adjustment of sensitivity for detecting metal particles. This feature enables the metal detector to be adapted to the type of product being inspected and specific safety requirements, providing an optimal balance between detection sensitivity and reducing false positives that could slow production.

Types of detectable metals

Industrial metal detectors can detect various types of metallic contaminants:

Ferrous metals: such as iron and steel, the most common in industrial contamination
Non-ferrous metals: such as aluminum, copper, and brass, requiring specific sensitivity
Stainless steel: the hardest to detect but critical for food and pharmaceutical safety

Application sectors

Metal detectors are used in numerous industrial sectors where product safety is a priority. In the pharmaceutical sector, they inspect tablets, capsules, powders, and packaged products. In the food sector, they check packaged foods, ingredients, and finished products to ensure the absence of metal contamination. In the nutraceutical and cosmetic sectors, they ensure the purity of supplements and personal care products.
