GR

Can Testing Machine by Air
GR designs and manufactures leak testing machine for various types of metal containers or plastic containers. In our company, we have created a data bank for leak testing based on long term technology accumulation. This is the benchmark of can making industry. The data bank is not for profit, it is for science.

The Core is Software
For the leak testing machine, you are not buying a machine frame, you are buying a precise and scientific system to detect, this is the core technology of a leak testing machine. Do not evaluate the machine on weight or appearance, evaluate the machine on software program.

In-Line Leak Tester
All our leak tester for metal cans or plastic cans can be installed after the production line, then the cans are conveyed to the leak tester directly, the complete process is fully automatic, the conveyor to connect can tester and production line is available.

Based on Real World Data
In order to explore the technology path, except the machine manufacturing, GR also emphasizes the software development. Through the technology service and communication with our expertise customers, we have accumulated rich experience and turn it into scientific data. In our technology department, we have created a data bank which is unique in this industry, and formed a strict but realistic standard for leak testing on each type of container.

Based on Real World Research
The source of our big data is definitely not from hypothesis, it is from experimental practice which is proven worldwide. For each customer, our engineers will study the test data according to the product types. We also collect each type of containers to repeat testing in our lab. During many years development and research, we have accumulated tons of data, and formed clear ideas. For different type of container, we do not roughly set a standard and execute mechanically, we analyze the micro difference between each style of containers, demonstrate repeatedly with an almost picky experimental design.

Based on Randomized Controlled Trial
In order to discover the influence of different factors, we carry out experimental studies under the guide of randomized controlled trial for various types of containers, including the inflation time, inflation delay, inflation pressure, sheet thickness, can beading style, testing head style, movement mode, container volume etc. This is totally scientific and objective. After a series of randomized controller trial, we use statistics to analyze. When you discuss the testing topics with us, we do not mind if your question is too complicate, we only mind if your question is too simple.

Based on Algorithm
The results of our years of research have been integrated into the program, you just need to easily press the touch screen easily, and the test system will analyze each condition for you. Our knowledge is your indirect experience, through this test algorithm, you can transform indirect experience into direct experience.

Based on Customer Experience
Our trusted customer will response to us during the use of leak tester, if they have any question on the principle or technology of leak tester, we will explain and upgrade the machine for each customer, most of our can testers are customized for the specific project of our customer, we will upgrade the machine based on the feedback from customers.

Air pressure leak detector is basically powered by air, and air is needed in many parts of the machine. Not only the inflation used for detection needs air, but also the actions of auxiliary detection (such as sealing action, elimination action etc.,) need air, because the actions are performed and implemented by cylinders. It can be said that air plays an important role in leak detection. The air compressors in some can factories are not stable, and the air humidity in the working environment is too high, which often causes a serial of problems such as machine failures, component damage, unstable testing pressure, inaccurate testing, rusted cans, poor sealing, and insufficient elimination force etc. In order to solve these problems, we install two air storage tanks on the leak detecting machine, one tank supplies air for the inflation and detection, and the other tank supplies air for the cylinders, so as to ensure a stable supply of air during the operation of the machine. More importantly, the air storage tank is equipped with a drainage function. Just press a button on the machine, the air storage tank will automatically drain. All the solution ensures that the air used by the machine is dry and sufficient, stable and convenient. At the same time, our leak detector is equipped with two pressure gauges with different ranges to independently control the air movement from the two air storage tanks, because the pressure used for inflating detection and the pressure used for cylinder action are not the same. It can be said that our leak detector is both sufficient and necessary. GR leak detector is the right-hand man of the quality assurance department, saving a lot of troubles for the manufacturing department.

The top can lids of square cans or rectangular cans are usually made with nozzles. For the empty can detection, the seal head of testing machine can be designed as two styles, one of the styles is designed as round and press on the nozzle of tin can, the other style is designed as square or rectangular and press on the whole can lid, then the seal head is bigger than the can lid. If you select the nozzle type seal head, when you feed the cans into the linear tester, you should keep the nozzle in the same direction. If you select the whole lid seal head, ignore this problem, regardless the direction of the nozzle, the seal head can press the whole can lid.
