滚塑模具与注塑模具生产工艺区别：
The difference between the production process of rotating and injection moulds is as follows:
滚塑是一种塑料中空制品成型工艺，成型过程中模具一直在旋转而得名：粉状或糊状物注入模具内，通过对模具加热和纵横向的滚动旋转，使物料借自身重力作用和离心力作用均匀的布满内腔并且熔融，待冷却后脱模而得到中空制品，由于是重力旋转加热很容易产生气泡和原料分布不均的现象，造成产品质量下降;一般生产时间较长，需要一层一层的向模具上涂布原料，几十分钟才完成，生产效率低，但是其生产设备投入成本少，模具开发简单，外观要求低，适合对产品强度要求不高产品。
Rotary plastics is a kind of plastic hollow products forming process, the mold has been rotating and named: powder or paste is injected into the mold, through the heating of the mold and the rolling rotation of the longitudinal and transverse direction, so that the material by its own gravity and centrifugal force uniformly filled the cavity and melted, to be cooled after demoulding and get in. Empty products are easy to produce bubbles and uneven distribution of raw materials due to gravity rotating heating, resulting in a decline in product quality. Generally, the production time is long, and it takes several dozen minutes to coat raw materials layer by layer on the die, which results in low production efficiency. However, the cost of production equipment is low, and the development of the die is simple. Low outlook requirement, suitable for products with low strength requirement.
注塑是在一定温度下，通过螺杆搅拌完全熔融的塑料材料，用高压射入模腔，经冷却固化后，得到成型品的方法。一般通高压喷射头把高温搅拌均匀的液体原料一次性注入密闭的钢模内，经过冷却得到成品，一般在几分钟内就可以完成，可以批量高效生产，但是其确实是生产设备一般价格都很高，经济投入较大，模具要求高。注塑工艺生产的产品一般致密高、韧度和强度好;生产出来的产品一般使用年限都达到几十年以上不会出现开裂和变脆的现象。
Injection moulding is a method of obtaining the moulding product by injecting the fully melted plastic material into the cavity with high pressure through screw stirring at a certain temperature and cooling and solidifying. Generally, the high-pressure jet head injects the liquid material which is stirred uniformly at high temperature into the closed steel mould at one time. After cooling, the finished product can be finished in a few minutes. It can be produced in batches with high efficiency. However, it is true that the production equipment is generally expensive, the investment is large, and the requirements of the mould are high. The products produced by injection moulding process are generally compact, tough and strong, and the products produced generally have a service life of more than several decades without cracking and brittleness.
