EspañolAutomotive Mold is a product we see every day, which is used in various interior and exterior decorations of automobiles, such as plastic bumpers, shock absorbers, instrument panels, etc. Therefore, we can't let go of any detail when processing, so today I will talk about some key points that need to be paid attention to when processing automobile molds.
Automotive injection molds have much higher requirements for processing equipment than traditional injection molding. Generally, there are two methods for processing.
The first is to use a mirror spark machine for processing, just to ensure the high precision of the product, it is best to use graphite electrodes for EDM processing because the loss of graphite electrodes is much smaller than that of ordinary copper electrodes.
The second is our usual processing method, which is the electroforming mold. The use of electroforming technology can ensure that the mold has good accuracy, but the disadvantage is that the processing time is relatively long, and each cavity must be processed independently. In addition, once minor damage occurs during the production process, it cannot be repaired, and the damaged acupuncture points can only be replaced.
In terms of molds, mold temperature is also a very important parameter for auto parts molds. Auto parts mold processing faces high-end consumers. Now we generally use the concept of high-gloss injection molding and introduce rapid heating and cooling systems.
Generally speaking, high mold temperature is very helpful to auto parts molds. For example, it can prevent thin-walled filling difficulties and lack of material. It is just that too high mold temperature will bring new problems, that is, cycle lengthening and The problem of shrinkage and deformation after mold opening.
Then it is very important to introduce a new mold temperature control system at this time. The mold temperature can be increased during the injection molding process so that the melt can fill the cavity faster, and prevent the melt temperature from falling too fast during the filling process. As a result, the filling is incomplete, and during demolding, the temperature of the mold can be quickly reduced and kept at a temperature slightly lower than the thermal deformation temperature of the plastic, and then the mold is opened and ejected.
Whether in auto parts mold processing or design, AOXU can provide auto suppliers with better quality Auto Parts Mold. The AOXU design team can effectively and accurately analyze the feasibility of the product in the early stage according to customer requirements, and analyze the bright spots, color differences, skin texture strains, tiger skin patterns, flow marks, water locks, and weld marks that may appear in auto parts molds. The evasion plan can be made in advance, and the designed mold has a good cooling system, exhaust system, and optimal injection system.
