How To Use Garment Metal Detector To Get Accurate Results?

Mon, 17 Feb 2020 15:22:42 +0530

All the garments need to pass through the garment metal detector before they are packed in cartons and leave the factory of the owner. This is really important for garments that are exported to other countries like Japan, European countries and the American market. The detection is done in order to check whether there are any kind of undesirable metallic substances and broken needles embedded or leftover in the garment and accessories that are been manufactured in the seeing process.

These are important because they can cause bodily injuries to the people using these products. These are especially dangerous for children who are not able to protect themselves against any kind of danger.
However, there are several factors that can result in the inefficiency and inaccuracy of the process of detection. In this post, you will get to see the top two factors that can fail your garment detection.

The Process of Manufacturing

The manufacturing of the garments often involves several different technologies and ways that can convert your used raw materials into complete finished goods that can be worn. The garments metal detection can fail because of the special treatment that is done before or sometimes after the production which does not get disposed of the property.

Therefore, the detector will only respond to the following:

• Metallic debris which sometimes remains in the place where the sewing needle hit the zipper.

• The metal powder which adheres to the fabric of the garment during the process of sewing and manufacturing process.

• Certain types of chemical materials or substances that get stuck to the zippers or fabrics in the process of washing or other such processes that take place in the factory during production.

• Certain kinds of dyestuffs.

• Impurities of metal that stick to the garment and results from such substances that accompany the special process of stone wash.

The Needle Detectors

Most of the detectors these days are sensitive enough in order to ensure the accuracy of detection. However, there are different types of detectors that are inconsistent sensitivity of the detection unit as well as different directions and positions in which the needles pass through the detectors which will lead you to different sensitivity levels and results in detection differences.

If the garments being checked are placed in the part of that features extremely weak sensitivity or are extremely strong, or when the garments are being inspected are not placed within the area of detection where they should be, the heating result will not be accurate. In addition to that when magnetic substances, dust or stain adhere to the conveyor belt, the detector is sure to malfunction and result in a false alarm.

There are other factors as well like the broken needles, trimmings and garment accessories that can lead to the inaccuracy of the garment metal detector. In order to get the perfect results, one should make sure to check these factors before the test is done. Only then the garments can clear the test and will be ready to be packed and exported.

A Complete and Detailed Guide to Spices Metal Detectors

Thu, 08 Oct 2020 14:21:50 +0530

Spices Metal Detector Systems have been designed to verify any free flow bulk powder or granular materials like medicines, pellets of plastic, cereal, spices (full / soil and spice-prone), sugar, rice, and chemical products. Any fluid free substance can be transmitted through the vertical drop system. The unit fits into or under an existing pipeline and the material is reduced by gravity.

Technologically progressing, metal detectors have been built into microprocessors, ranging from valves to transistors and circuits. This has, of course, increased their efficiency and improved their sensitivity, reliability, and versatility, and enhanced the range of output signals and data.

Control and the Signal Processor:

Depending on the device configuration and configuration, controls can be built on or remotely on the search head itself. The output of the system is not compromised when the controls are installed. The signal processor is very advanced. If a standard metal particle is "illuminated" A transmission frequency of one-millionth of a volt on the receiver coils. This is first enhanced and then modulated to a low frequency via a high-performance RF amplifier. This gives details about amplitude and phase. In order to maximize sensitivity, the signals are digitalized and digitally processed.

Magnetic Field Systems:

The detection theory of these metal detectors from spices metal detector suppliers is entirely different. They operate in a tunnel or a passage that is exposed to a strong magnetic field and so any magnetic material is magnetized as it passes through (such as a metal fragment with a ferrous content). A variety of coils are used in the tunnel. When the magnetized object moves through the detection device a voltage is produced that is amplified and used to activate the detection signal produced by the electronics.

User Interface:

The user interface allows the communication with the device so that the program, the framework, and the mechanical handling system can be configured and optimized. A number of network communication, statistics, and device information have been enabled by computer processors.

Sensitivity:

The search head should be of the size suitable for the specified food product for maximum sensitivity. The best sensitivity for each product in terms of scale, form, and packaging is to be defined and set. Only in coordination with your metal detector manufacturer should such a procedure be performed.

You have to reassess your system once more if you switch your detection systems on your premises or if you implement new products in consultation with your producer. Many leading retailers would advise their private label consumer suppliers to consent, in writing, to any improvements in the metal sensitivity settings.

Untrained workers should not be able to access sensitivity change controls. Controls must be password protected or locked only for designated fully qualified workers and for further protection.

Testing Procedures:

The protocols for spices metal detector testing shall be clearly recorded and communicated to all workers concerned. At the beginning of each transition, between each product change and in any case, at least hourly testing shall be performed. Test periods must be short enough to allow potentially damaged goods to be detected, recalled, and re-tested if a fault is found. Once more, ensure you consent to any compromise you make with your retail clients if your business is a producer of private labels.

The Working Mechanism Of A Metal Detecting System

Fri, 11 Dec 2020 14:37:26 +0530

With rapid growth and development of technology, many things around us have got transformed. Just like computers and other gadgets have made the entire world a global platform, tech in military services has made the world safer. One of such great invention in the field of security service is metal detectors. It has been a device of great help as it helps by uncovering knives, guns and other such buried mines easily. These metal detectors make use of the principle of electromagnetism.

Working of the device:

Before starting with the working mechanism of these metal detecting systems, we need to first one what is an electromagnet. When a piece of iron is wrapped using metal wire and electricity is passed through it, the piece of iron starts acting like a magnet. Electromagnets are very strong and can easily attract large pieces of iron too. The concept of electricity and magnetism walk hand in hand. Electromagnets are used in several useful devices around us like wind turbines, washing machines, etc.

It can be said that when electricity is used to produce a magnetic effect, it is called electromagnetism. These metal detectors use electromagnets which makes use of electricity or battery to create a magnetic field. Now, these magnetic forces help in determining and detecting the presence of metal bodies nearby.

The power source of metal detectors:

There are many kinds of metal detectors like gravity feed metal detector and each one of it works in different ways. However, the basic science behind the working of all of them is similar. The metal detectors have wires coiled in it. A similar setting is found near the handle of the metal detector. Thus, forms the transmitter coil.

Now, when the switch of the detector is turned on, electricity starts flowing in the coil creates a magnetic field. Now, when the detector is swept over the ground or some item, with the help of a magnetic field, it feels the atoms of the metal object which is present in there.

Next, there is another magnetic field working in the detector. There is another coil which is coiled near the head of the detector. This receiver’s coil is connected to a loudspeaker. As soon as the first magnetic field detects the presence of the metal body, the second magnetic field results in the production of the beep sound. This is how the metal source gets its power supply and works.

There are many metal detecting system manufacturers in India who manufactures the best quality devices. These devices have been of great help and are now used commonly at every public place where the checking has been mandatory

To Know More About Tablet Metal Detector

Fri, 29 Jul 2022 12:49:57 +0530

Metal contamination in goods or packages is found using tablet metal detectors in the food and pharmaceutical sectors. Due to the existence of metallic pieces or components in ferrous, non-ferrous, or stainless steel materials, metal contamination may happen in food and pharmaceutical items.

The identification of such metal contamination is crucial, and great precision and reliability are desired in the detection procedure. Consequently, a metal detector is crucial for maintaining the security of the goods. Additionally, metal detectors safeguard machinery and control compliance in the food and pharmaceutical sectors. Tablet metal detectors also contribute significantly to upholding the company's image.

In the pharmaceutical sector, there is a chance that magnetic or non-magnetic metallic pieces will contaminate the goods. This results from the use of various process equipment, such as reactors, agitated and storage vessels, classifiers, dryers, pumps, valves, pipes, etc. in the synthesis, processing, and storage; the majority of this equipment, pipes, valves, and pumps are made of metals.

This contamination also results from contaminated ingredients, mixing-process errors, and machinery failures. For instance, combinations comprising potassium, chromium, copper, aluminium, and other metals are employed in large-scale dehydrogenation operations. Nickel, cobalt, platinum, palladium, and other metals are also utilised.

These are many metal detectors with distinct functioning principles. Below, some of the more popular metal detectors are mentioned.

Measuring electromagnetic induction

These metal detectors function according to electromagnetic induction theory. One or more inductor coils are employed in metal detectors to interact with metallic components on food or drug goods. The detector's construction ensures that the metal components from tablets are automatically removed without halting manufacturing. This kind of metal detector is typically used to find metal contamination during the production of continuous tablets.

This kind of tablet metal detector is simple to maintain and works well with all tablet presses. It is highly sensitive to all metals, including the most challenging stainless steel that isn't magnetic. Throughout its lifespan, its performance is maintained consistently.

Receiving and transmitting on many frequencies

This kind of tablet metal detector operates on a multi-frequency transmission and reception basis. For the transmission and reception of many frequencies in metal detection, multi-coil configurations are employed. The signal that the receiver sees is enhanced by the multi-frequency produced by the multi-coil configuration. Multi-coil configurations can increase the instrument's detection performance by up to 20% when compared to a single transmitter and two receivers.

The key standards for pharmaceutical sector products are quality and integrity. Whether it is for generic alternatives, over-the-counter solid dose products, or ethical pharmaceutical formulations, effective product protection is essential throughout the manufacturing and packaging processes in the food and pharmaceutical sectors.

Electromagnetic waves

A transmitter antenna in radiofrequency metal detectors generates radiofrequency waves between 300 kHz and 1 MHz. On either side of the transmitter, two reception antennas are placed at an equal distance from the emitter. The difference between the two signals is zero when the system is balanced and there is nothing magnetic or conductive inside the metal detector's aperture, indicating that no metal is present. There is a visible imbalance produced when metal is present and moving through the detector. These three elements affect how accurate these metal detectors are.

Measurement at a very low frequency

The most widely used metal detectors operate under the Very Low Frequency (VLF) measuring principle. The energy is continuously pushed into the earth and pulled back up as a result. Any metallic or conductive item that gets in the way of the magnetic field is affected by it. Every time the metal detector passes over a conductive item, the receiving coil transmits an electric current. The frequency of the current is amplified and sent to the control box in this way, utilising metal detectors

With the use of VLF technology, metals may be found and their depths and various sorts of metals can be distinguished.
