Hot Press Molding Machine for Glass Fiber Composite Material
Glass fiber board mobile phone back cover 2.5D, 3D, 3.5D composite sheet, PC injection imitation glass, IMT, IMD industry chain, mobile phone terminals such as Xiaomi, Huawei, OPPO, vivo and Tongda, Xinxiong, Zongsheng, Lens, Bourne , Hongchuan, Sanjing, Zhaoyi, BYD and other companies have joined in the production of fiberglass board materials. In addition to its application in mobile phone covers, fiberglass boards are also suitable for many product fields such as tablet back covers, e-cigarette casings, TWS headset back covers, automotive decorative parts, and home appliance panels.
In terms of the feel of the phone's back shell, the plain leather version is better. It provides users with a design that is more comfortable for the human body and is not easy to slip. The plain leather version is made of leather, which feels better than glass and does not need to be dropped on the floor. I'm worried that the back cover will shatter like glass, and more importantly, it won't attract fingerprints.
Thermoplastic refers to fiberglass cloth. This material is relatively cheap per square meter (previously used to support flexible circuit boards or fix concrete walls). It is pre-impregnated with epoxy resin and then heat-dried to form a cloth with a soft texture. , and then hot-pressed and maintained through mirror-surface male and female molds, the same as vulcanization.
Process of hot press molding machine for glass fiber mobile phone back cover:
Fiberglass + PU plain leather (this HW is a process that has already been shipped, fiberglass hot bending + hot melt adhesive lamination)
Fiberglass board + cover bottom + UV transfer + electroplating + lamination hardening or UV transfer + hot bending (it is not easy to remove the texture in some cases, so multiple printing or lamination or transfer priming is required) Or scratch-coating the base, which is not ideal for glossy texture, but matte is OK. The heat bending temperature of glass fiber is high, so it is a test for ink plating)
3D formed fiberglass board + 3D formed IML film film lamination (that is, first heat press the fiberglass board into a 3D arc + hot melt glue + 3D formed and decorated IML film PET) This method is not recommended. I tried it, but the yield rate couldn't increase.
3D forming glass fiber + IMT film lamination and transfer process (this is the latest process, the fiberglass plate is hot-bent + hot-melt adhesive + bottom cover + electroplating + texture + hardened layer + release + bottom film. Simplification is in the hot-bending process The IMT film is directly 3D bonded to the final glass fiber board. Of course, there are difficulties here, including the bonding equipment process and the selection of the IMT base film. Some people may say that the surface hardness is not enough after the IMT film is torn off. This is not the point. You can spray it again. Primary high hardness hardening fluid)
