1, due to PC/PMMA is an optical level of high-transparency materials (and glass transmittance close to), and then the battery cover is an appearance of the parts to be very good to the PC surface UV texture and sputtering effect set out, all the external surface can not have any damage, all with "air" this flexible pressure to mold is the most suitable for the key because the air in the closed cavity by the same pressure on the vertical surface, all the products are made out of the product surface is "zero" damage. The key because the air in the airtight cavity in the vertical surface of the pressure are the same, all the products made out of the surface of the product is "zero" harm.
The emergence of IMT process will replace the industry's oil spraying, UV overlay, electroplating, vacuum color plating, silk screen, pad printing and transfer printing process, will drive the product appearance industry leapfrog innovation, the realization of the three-dimensional three-dimensional, color gradient, R-angle and other irregularities in the product appearance decorative effect, and at the same time to the appearance of the process design industry to provide a better platform to realize the innovation and platform.
The new IMT process combined with the most popular 3D optical texture + PVD decorative method, compared with the traditional value is higher, the arc is larger, the current IMT process, by the new process of 3D optical texture + PVD based on the double + 3D optical texture + PVD.
2, high-pressure molding machine principle:
No upper molds, only the lower molds, the use of gas high pressure will be added to the mold. Mold, the use of gas high pressure will be heated and softened sheet, directly pressed on the lower mold to complete the molded parts. After heating the film material to the softening point and then closing the mold, the high pressure air in the upper mold cavity is pressed from top to bottom by segmented high pressure, and the lower mold cavity is vacuumed, thus making the film material and the mold perfectly jointed together.
3, high pressure molding machine suitable materials:
PC, PC + PMMA, ABS + PMMA, etc. PMMA/PC composite sheet, both to meet the requirements of rigidity and decorative, but also to meet the need for wireless charging without shielding, PMMA provides high hardness and weather resistance, PC impact resistance and good molding performance.
4, high-pressure molding machine product applications:
Smart windows, 3C shell, cell phone cover, automotive instrumentation, automotive interior parts, control panels, smart lock shell, label printing, nameplates, model shells, battery shells and other related electronic products.
5, high-pressure molding machine product advantages:
Composite corners do not whiten, do not leave the layer, stainless steel drawing material does not pull the cracks, do not break, IML products around the perfect backpacking a molding.
6, product features:
1, the use of servo systems, low noise, energy saving and environmental protection, can reduce electricity consumption of up to 46%, less heat, low oil temperature operation (within 50 degrees), which can extend the service life of the hydraulic machine, reduce production costs.
2, unique heating system device, can be segmented, zoning control temperature and pressure, the overall temperature difference can be controlled within 3 degrees, to ensure the stability of the temperature of the hot press, greatly improving the yield of the product, the maximum can reach more than 95%.
3, the precision design, greatly reducing the size of the equipment, covers an area of less, the same area can increase the placement of equipment, can also be placed on the second floor.
4, can be quickly warmed up, cooled down, and does not require expansion tray, greatly improving production efficiency.
5, the equipment is equipped with ceramic heating brick baking tray, can instantly heat the special film to 600 ° -1000 °, saving baking time, improve production capacity.
6, the lower mold plate can be connected with external oil heater to ensure that the temperature of the lower mold is stable at ±1°, so as to ensure the yield of the products.
7, high-pressure molding machine is mainly used in:
1, 3C industry: NB panel, cell phone back cover, flat computer panels, notebooks, mice, cell phone buttons, cell phone lenses, landline phone panels, window lenses and so on.
2, home appliance industry: washing machines, microwave ovens, air conditioners, refrigerators and other control decorative panels.
3, electronics industry: calculators, electronic notepads, digital cameras, ultra-thin batteries and other decorative surface shells, color shells and signs.
4, the automobile industry: instrument panel, air conditioning panel, interior parts, lamp shells, signs.
5, other industries: smart locks, helmets, medical equipment, cosmetic boxes, decorative boxes, toys, sports and recreation and leisure goods, etc. ?
8, the cell phone industry: at present, the application of cell phone cover plate material is mainly metal, glass, ceramic, plastic (composite plate) four. But with the outbreak of 3D cover, as well as the development of 5G communication and wireless charging, metal will be gradually eliminated, glass and ceramic should be the standard in the post-4G era. For 3D composite cell phone cover, due to low cost, high yield, beautiful appearance is one of the biggest trends in the future 3D back cover .
Automotive industry: touch screen, air conditioning panel, window lifter, gear shifter cover, cup holder cover, back cover, instrument panel, interior parts.
In the 5G era, the IMD process is likely to become very popular, IMD technology can be fused with electronic technology in the future to evolve into IME technology, increase the circuit layer and mounting of electronic components, giving the film electronic functions and a variety of visual, tactile, sensory effects, applied to the future of the car's intelligent surface.
9, high-pressure molding machine operation process:
1. Cylinder extends, push the plate up.
2. Put the diaphragm.
3. Both hands button, the lower mold rises.
4. Pusher plate and lower mold rise together to the set position of the touch screen and stop in the middle.
5. Start to bake the diaphragm.
6. Lock the mold.
7. Fill the compressed air, the diaphragm is molded, and at the same time close the push plate cylinder.
8. Exhaust air.
9. Open the mold.
10.The lower mold is lowered into place.
11.Take out the molding diaphragm manually.
12.Cylinder extends and pusher plate goes up.
13.Release the diaphragm.
