Can large molds be held in place?
The magnetic template uses neodymium iron boron, a rare earth permanent magnet material with high magnetic energy product, as the latest result of the development of rare earth permanent magnet materials. Due to its excellent magnetic properties, it is known as the "magnetic king". The neodymium iron boron magnetic material is neodymium, and iron oxide is an alloy, also known as magnetic steel. Neodymium iron boron has extremely high magnetic energy product and coercivity. Magnetic template design: A single template can withstand the weight of the entire mold. The weight of large car bumper molds is generally 35-45 tons, and they can also be easily clamped onto magnetic templates for use.
Will a power outage cause mold loss?
The magnetic template is designed based on the principle of electrically controlled permanent magnet technology, and its biggest advantage is that it will remain magnetic even after power failure. Electric energy is only used during the instantaneous conversion of the magnetic circuit between excitation and demagnetization (only 1-3 seconds), and during other times only the system operates and uses electricity.
How long can magnetic force last?
As is well known, the decay of magnetic properties of magnets is a very long process, so the service life of magnetic templates can exceed thirty years or even longer.
Is magnetism harmful to the human body?
After the magnetic template is excited, there will be a magnetic field present on the working surface, which is a permanent magnetic field rather than an electromagnetic field and poses minimal harm to normal human health. The radiation space of magnetic field lines is also within a limited range of tens of millimeters. Individuals with medical devices embedded in the human body should consult a doctor. In addition, magnetic templates will generate attraction to ferromagnetic materials such as wolf heads, wrenches, watches, etc., and credit cards, ID cards, etc. are strictly prohibited from approaching to avoid demagnetization failure. Will high injection molding temperature cause suction attenuation?
The magnetic materials assembled into the magnetic template have undergone strict temperature resistance testing, and the products leaving the factory are divided into two levels: 120 ℃ and 150 ℃. Can be applied to the production and use of plastic products.
Can the factory power supply be used if it is unstable?
The magnetic template only uses electrical energy during excitation and demagnetization, and does not consume electricity at other times; The controller system is designed with intelligent constant current control output, which can be used normally even when the external power supply is unstable.
Do we need to modify the mold? Can the mold with added insulation board be used?
Install an electric permanent magnet quick change mold magnetic template, most molds can be used directly. For asymmetric molds of the opposite sex, it is necessary to consult the manufacturer for evaluation before use. In addition, molds with installed insulation panels cannot use magnetic template systems.
The material used to make mold insulation boards is generally non-magnetic material with poor thermal conductivity, so it cannot be directly used. If the insulation board is installed between the magnetic template and the injection molding machine wall panel, it is completely feasible.
Is the maintenance and usage cost high in the later stage?
Because the system only uses electrical energy at the moment of excitation and demagnetization, the aging speed of each component is very slow, and there are no moving parts inside the product, so the magnetic template does not require frequent and tedious maintenance and repair, and the cost of use is almost zero.
