（1）顶注式：金属液从型腔顶部注入。其优点是精密铸造生产厂家能使金属液由型腔下部向浇口部分顺序凝固，这样能获得组织致密的铸件。缺点是浇注时金属液容易产生飞溅；对铸型的冲击力大，容易使铸件产生夹渣和气孔。铸件越大这种缺陷越显著。所以，这种形式只适用于高度较低的铸件。
（2）底注式：这种方式的优点是，金属液能平稳地从型壳的下部注入，型腔中的气体能自由地从上部（冒口或出气口）逸出，故有良好的出气排渣作用（蛇形浇口的集渣效果更好），浇出的熔模精密铸造件表面光洁。这种形式尤其适用于浇注铜、铝等有色合金铸件。其缺点是底部与顶部的金属液温差大，易产生缩孔、缩松、裂纹等疵病。为此，必须要有较高的压头并相应增大浇注速度或从顶部补浇高温金属液以减少整体型壳的温差。
