Plastic hot press machine is a multifunctional industrial equipment that completes the processing and molding of various materials through precise control of temperature and pressure. The following is a detailed explanation of its typical application scenarios and process characteristics:
1、 Electronic component processing
Production of protective covers
Mobile phone/iPad protective case: Made of PVC/TPU and other materials, the leather or silicone is bonded to the hard lining through hot pressing, and the edges are cut in one go, with high efficiency.
Keyboard leather cover: The hot melt process combines microfiber leather with EVA foam, and holds it under pressure of 0.3-0.5MPa for 10 seconds to ensure that there are no bubbles in the key positions.
Precision component processing
PCB bending indentation: Low temperature hot pressing at 80-120 ℃ to avoid deformation of the circuit board, precise pressing of V-groove bending lines with small tolerances.
Nut hot melt implantation: Metal nuts are hot pressed into plastic shells at 200 ℃,The tensile strength test needs to reach 50kgf or above.
2、 Leather Craft Application
Surface Treatment
Embossing/embossing: The mold temperature is controlled at 150-180 ℃, and three-dimensional patterns (such as lychee patterns) are pressed onto genuine leather or synthetic leather. The pressure parameters are usually 0.8-1.2MPa.
Leather bonding of battery cover: UV glue is pre coated and then hot pressed to cure, avoiding the overflow problem of traditional glue.
Special process
Cold press setting: For temperature sensitive materials (such as carbon fiber film), room temperature high-pressure setting is used, with a pressure of at least 2MPa.
3、 Key points of quality control
Temperature accuracy:Temperature fluctuations affect the shrinkage rate of TPU, and precision must be strictly controlled.
Pressure balance:The cylinder structure achieves uniform force distribution through a mechanical automatic deflection compensation mechanism, which is suitable for the machining needs of large-sized workpieces.
Efficiency optimization: Quick mold change design can shorten the machine switching timeSimplify the mold replacement process.
Case reference: A Shenzhen manufacturer used a duplex hot press machine to achieve synchronous completion of phone case lamination and punching, significantly improving the yield rate. ?
