The effects of preforming duration, preforming pressure, extrusion die's geometry size and content of lubricant on the extrudate's tensile strength were studied.
研究了预成型时间和压力、挤出模具几何尺寸、助挤剂含量等对挤出物强度的影响。

Furthermore, the property of die castings have also been affected obviously by other process parameters, such as time of intensified pressure, mould temperature, billet temperature and lubricant etc.
另外建压时间、坯料加热温度、模具预热温度以及脱模剂等参数对半固态压铸件性能也有明显的影响。

It is unnecessary to fill lubricant every day, equipped with a falling pressure lose protective device for broken hydraulic tubing and a lifting arm gyro angle lock unit.
