Shanghai Gaojing Metal Detector Instrument Co., Ltd. founded in 1998, is the predecessor of Shanghai High-precision Electromechanical Research Institute and has the dominant share of Shanghai Gaojing Image Technology Co., Ltd. and Shanghai Gaozhan Electronic Equipment Co. Ltd. It devotes itself to the research on food safety technology and public security technology, development, production and marketing of products.

We take responsibility for developing, producing and selling various kinds of metal detectors. Our products include metal detectors, needle detectors, x-ray impurity detectors, x-ray security inspection machines and walk through security doors. All of these together with our total solutions can meet customers' different requirements. Our saleroom has ranked the first for many years in the domestic market.

In 2005, GJ-VIII digital metal detectors won the honor of "Shanghai Key New Product", which have LCD screen and digital adjustment function. After the strict test by the Germany experts, we have already received an order of 300 sets equipment in 2005, which fully shows our ability.

At the same time, our x-ray impurity detectors, which can detect stone, hard plastics and glass pieces, have been successfully developed into two types. One can detect small packages with the weight 5kg below, and the other with 5kg above. Through many doctors' hard working, we have already grasped the core technology of this machine, which leads to a big decrease of cost. Our goal is to make the x-ray impurity detectors enter into food factories with low cost and high performance.

In 2006, we will work out our GJ-IX metal detectors, which will be integrated self-learning function and frequency adaptation techniques. The GJ-IX metal detectors also have LCD touch screens, printer interfaces and central controllers. Customers can use this kind of detectors conveniently just as personal computers. The GJ-IX series of metal detectors is the main product competed with the overseas counterpart, and is the milestone showing that our metal detection techniques has entered into the top level in the world.

In addition, we have established Gaojing Laser Instrument Co., Ltd. and developed new types of laser marking machines. Compared to traditional jet ink printers, these laser marking machines have such advantages as without consumption, no pollution and anti-forgery.

In the needle detection area, our GJ-VI series of metal needle detectors enjoy a good reputation worldwide. Taking 400 x 230mm aperture as an example, the bottom sensitivity is 0.8mm steel ball and 1.0mm steel ball in the center. It also can detect steel, stainless steel and copper. We have strengthened our R&D team and will develop many new products so as to serve our customers in clothing and plush industries.

During our producing procedure, we comply with ISO9001 standards, and pursuit perfect quality management. Now, we have almost 5,000 customers and our products are used in different industries. Some of them are exported to America, Canada, Europe and Thailand.

Last year, we have invested almost USD 6,000,000 for new product development. The majority of our R&D employees have master degrees and we also employ many engineers as well as some senior engineers and doctors. Our R&D team keeps up with the new technology and develops kinds of leading metal detection instruments. Besides, we have cooperated with international famous metal detection companies so as to make the most recent technology outcome apply in production.

If you are interested in any of our products, please feel free to contact us for more information. We look forward to cooperating with customers both at home and abroad.
