Disadvantages: not scratch-resistant, not resistant to strong acid, not resistant to strong alkali, not resistant to ultraviolet light
II. Transparency
1. Silicone
Silicone has high transparency.
2.TPU
From the outside, TPU can be made very transparent.
3.PC
High transparency, PC material protective case is also very good light transmission. However, the high transparency of the PC protective shell production process requirements are relatively high, translucent PC shell is still relatively common.
Third, processing and molding
1.Silicone
The use of liquid silicone material through the secondary injection molding process, the surface feel delicate, waterproof and non-slip, because the liquid silicone has excellent elasticity and memory, so that the cool case to deal with the impact of the bump can be realized efficiently cushioning, preventing damage to the phone at the same time, compared with the hard plastic shell, itself is not easy to damage. It can be said that the use of liquid silicone material cool case in the physical protection is a higher level.
Surface treatment:
Monochrome cell phone cover, this kind of cell phone cover is only the deployment of silicone color, with the shape of the mold to make a three-dimensional plane of the silicone cell phone cover, generally need to be post-processing, such as: silkscreen, color printing, digital printing, water transfer, thermal transfer, laser engraving, oil spraying and so on.
2.TPU
TPU belongs to the plastic category, the product is injection molding process to do out, that is, a grain of plastic rice after heating and melting, with the barrel of the gun shot into the plastic mold and made products.
Surface treatment: plating, spraying, printing, etc.
3.PC
PC can be injection molding, extrusion, molding, blow molding, thermoforming, printing, bonding, coating and machining, the most important processing method is injection molding.
Surface treatment:
Vacuum plating process: plating on the PC shell, plating after carving some patterns, texture is good, but after the vacuum plating after one to UV varnish.
PC spraying process: you can spray the feel of rubber oil, this feel also has a lot of people like, and then a little more complex is in the colored (transparent red, transparent blue, transparent yellow, etc.) transparent PC shell on the spray a layer of primer, and then laser engraving of some patterns, and finally over a rubber paint, this product appears to be very high-grade.
PC water transfer, thermal transfer process: in the PC shell to do some transfer on the pattern pattern, and then spray UV varnish, or have a soft feel of the rubber oil.
Transfer after spraying UV varnish, hand pinch, the surface of the UV varnish is easier to crack, so the transfer process is best to choose to spray rubber paint, soft touch, matte surface, do a good job of the process, it will also look very high-grade. The disadvantage is that the surface is not scratch-resistant, if a partial loss of paint, sparingly along the place where the paint will easily fall off more and more. The advantage of transfer printing is that the pattern is very colorful.
