Engel X-Melt是一种用于生产小型和/或薄壁部件的非传统工艺。传统上，薄壁模制涉及螺杆在执行其向前运动时的高加速度和减速。另一方面，X-Melt使用储存在螺杆前面的压缩熔体中的能量。注射是影响简单地打开针阀喷嘴，让熔体膨胀，并填补模具型腔。通过使用该工艺，较高的熔体前沿速度将允许填充比其他方式可能的更薄壁的部分，并且在微成型中，消除了由机械挡圈的闭合行为引起的工艺变化。
Engel X-Melt is an unconventional process for the production of small and/or thin section parts. Conventionally, thin wall moulding involves high acceleration and deceleration of the screw as it performs its forward movement. X-Melt, on the other hand, uses the energy stored in the compressed melt in front of the screw. Injection is affected simply by opening the needle valve nozzle, allowing the melt to expand and fill the mould cavity. Through the use of this process, a higher melt front velocity will permit filling of thinner wall sections than would otherwise be possible, and in micromoulding, variations in the process caused by the closing behaviour of the mechanical check ring are eliminated.
