Unlike compression molding, however, transfer molding includes heating the plastic to a fluid state before it gets to the mold and forcing it into a closed mold using a hydraulically actuated plunger.

与压缩成型，但是，传递模塑包括取暖的塑料流体之前得到国家的模具，并迫使它变成一个封闭的模具采用液压驱动柱塞。

R2 is the point of signal transfer between plunger and barrel.

R2是顶针与套壳体之间的信号传输点。

By the area difference between the piston and the plunger in their respective working Chambers, the hydraulic booster can transfer the input lower pressure into output high pressure.

水力增压器利用两工作腔活塞与柱塞面积之差，将输入低压转换为输出高压。
