What is the difference between pvc injection molding machine and pp injection molding machine?

1. 原料不同：pvc注塑机用于注塑pvc材料，pp注塑机用于注塑pp材料。

Different raw materials: pvc injection molding machine is used for injection molding of pvc materials, and pp injection molding machine is used for injection molding of pp materials.

2. 工作原理不同：pvc注塑机是挤出式机器，pp注塑机是模压式机器。

Different working principles: PVC injection molding machine is an extrusion machine, while PP injection molding machine is a molding machine.

3. 成型方法不同：pvc注塑机由模具和变压器组成，其成型方式是将模具中的塑料挤出，而pp注塑机是将塑料合金放入模具内，然后通过压力模压成型。

Different molding methods: the pvc injection molding machine is composed of a mold and a transformer, and its molding method is to extrude the plastic in the mold, while the pp injection molding machine is to put the plastic alloy into the mold, and then press it to form.

4. 成型效果不同：pvc注塑机适用于大批量生产，具有较高的注塑速度和质量。而pp注塑机的生产效率较低，但成型效果较好，可以生产出高精度的塑料制品。

Different molding effects: PVC injection molding machine is suitable for mass production with high injection speed and quality. While the production efficiency of pp injection molding machine is low, but the molding effect is good, which can produce high-precision plastic products.
