ZTL automatic air waste detection machine question
 
 
ZTL automatic air waste detection machine questions and answers to frequently asked questions
I asked: under what circumstances the need to use the waste detection machine?
A: The waste detection machines can be a reliable, high-speed, the stability of the detection of tiny hollow vessels leak so as to guarantee the quality of the products detected. Increased waste detection process, the defect can be avoided goods into the next process caused by leakage of canned, interruption of production, resulting in leakage of pollution. Therefore, the need to ensure good sealing of containers, bottles, boxes, various types of fittings and so on, will be used for waste detection machine.
Second, ask: Why waste detection pressure water pressure is better than waste detection?
A: The use of air pressure detection tests of the most important advantages is the objectivity of the testing process. This means that the results be repeatable and can be used for statistical analysis. In general, water can leak was detected, but vulnerable to man-made factors, and take much longer to get the results. So the question is how the samples in the underwater detection of the length of time. Most of the leak is detected is "obvious" leakage, for example, a large leak. Electronic device can quickly detect small leaks. Underwater test of the existence of other problems include: wet ingredients, as well as the spillover damage to the product or damage.
III: The testing pressure drop advantage of what?
A: Drop waste detection can be effective for a relatively small volume of waste detection products. Use of air compression products, equipment to monitor the pressure changes in the negative. If there is pressure to lower, then there is leakage. This method of detecting only a few seconds to arrive at the results, so widely used in large-scale industries, such as automotive products, castings, medical equipment and consumer goods of the waste detection.
 
IV Q: What occasions the use of dual functions of prosecution?
  A: The outside interference in the process of detection makes possible a very small number of false. Dual function of seized goods carried through the detection and comprehensive Detection 2nd test results on pieces of testing carried out to determine, making the system completely avoid the interference caused by the false happen. For some industries, such as pesticides, chemicals, packaging of dangerous goods such as containers, bottles found on the high quality requirements, recommend the use of the feature.
     
V. Q: Every time the number of products can detect how much?
  A: At the same time, can detect the number of products from waste detection machine of the number of channels decision. If Channel 2 can be detected at the same time 2 products. ZTL series waste detection machine can provide the greatest 6-channel models.
 
 
PET production summed up the problem (for reference only):
 
PET bottle embryo production techniques of Abstract:
In the injection molding process in the process of PET bottle grade sections of a number of defects analysis and solutions
1, the installation of the mold, a problem of one mind, it is necessary to confirm the installation of one mind in the order, if necessary, the need to re-install.
2, mold machining precision parts in question, whether or not to use the formal recognition of the mold parts, precision machining, please ask the manufacturer to die.
3, mold parts of the injury, damage, the proposed replacement of worn parts, re-examination of the conventional, petrol operation.
Stripping phenomenon:
The emergence of plastic injection mold is a bad phenomenon that may occur, resulting in a solution and the main reason is as follows:
1, the Department of lip-mode configuration of the hanging of Flash, Flash proposals to resolve the issue.
2 bottles of cooling embryo less than the proposed cooling pipe inspection route, including in-house mold cooling circuit and the functioning of the Lengshui Ji, the lower the temperature of cooling water.
3, PET drying less than the proposed inspection of the desiccant dryer operating conditions and inspection of the PET raw materials.
4, the plastic melting temperature is too high, proposes to reduce the barrel (front, central) temperature.
5, mold damage to parts of the (core bending, etc.), the proposed replacement of defective parts.
6, the unreasonable structure of the release or improper location, check the structure and location of the release.
7, mold temperature is too high, due to lower die temperature.
8, injection pressure is too high, due to lower injection pressure.
9, the use of release agent.
Gel
  Gel injection when it is possible, and the main solution is as follows:
A drop of water injection core, the shape of the bottle after its Tightlock embryo, which is caused by bad release, the appropriate recommendations to improve the cooling water temperature, check Die In addition to the disclosure of the functioning of the machine.
PET bottle production of embryos in non-performing analysis and recommendations:
 
Jiaokou fracture
    Embryo gate broken bottles appear from time to time injection is a natural phenomenon, which is caused by injection and the injection mouth is too short to plug reasons, and the main reason resulting solution is as follows:
    1, the temperature is too low heat flow nozzle, the proposal to increase the temperature of hot runner nozzles.
    2, the pressure used when the pressure is too high, reducing pressure when used in the pressure.
Partial albino
Bottle embryo is a partial albino injection when possible, have a solution and the main reason is as follows:
1. The previous gate into the debris caused by the white bottle embryo, which generally do not make a special deal with the unusual case of a certain period of time, or cleaning up mold.
2. Hot runner nozzle of the low temperature case, the proposed reduction of pressure when used in pressure.
Drawing
Bottle embryo is drawing appear injection when possible, and the main solution is as follows:
1. Heat over the nozzle temperature is too high, the proposal to reduce the temperature of hot runner nozzles.
2. Resin temperature is too high, the proposal to reduce the temperature of hot runner nozzles.
3. Used to keep the pressure too low, the proposed increase pressure when used in pressure.
4. Packing time is too short, the proposed extension of the time pressure.
5. Resin and dry enough, the proposed inspection dryer.
