一般客户有比较大产品需要做小批量生产可产品数量都没有达到上万个，这时候客户为了节约成本就会选用低压灌注的方式来制作，下面来讲讲低压灌注模型工作原理用途等内容吧

Generally, customers have relatively large products that need to be produced in small batches, but the number of products does not reach tens of thousands. At this time, customers will choose the low-pressure injection method to make them in order to save costs. Let's talk about the working principle and purpose of the low-pressure injection model

低压灌注是一种快速模具制品生产的新工艺，它相对注塑来说成本较低，由于它的产品都是 整体成型出来的，所以低压灌注生产出来的产品具有缩水和变形较小，有效率高、生产周期短、过程简单、成本低的优点，制作的产品强度也高。在当下的行业情况下来说客户的需求是越来越大。

Low pressure pouring is a new process for the production of rapid tooling products. Its cost is lower than that of injection molding. Because its products are integrally molded, the products produced by low pressure pouring have the advantages of small shrinkage and deformation, high efficiency, short production cycle, simple process, low cost, and high product strength. In the current industry situation, the demand of customers is growing.

低压灌注成型的工作原理：将预先配制好的多组份聚氨酯材料经计量泵以一定的配比送入混合头经混合后，在低压环境下注入快速模具内，通过材料的聚合、交联、固化等化学和物理过程形成制品，注入量由泵的单位吐出量和注射时间来控制。

Working principle of low-pressure injection molding: the pre prepared multi-component polyurethane material is sent to the mixing head through the metering pump in a certain proportion. After mixing, it is injected into the rapid tooling under low-pressure environment, and the product is formed through chemical and physical processes such as polymerization, crosslinking and curing of the material. The injection amount is controlled by the unit discharge of the pump and the injection time.

低压灌注的用途：山东快速成型厂家认为其适用于产品开发过程中的小批量试制，以及小批量生产的、结构较简单的覆盖件和大型厚壁及不均匀壁厚制品的生产。

Application of low-pressure pouring: Shandong rapid prototyping manufacturers believe that it is suitable for small batch trial production in the process of product development, as well as the production of small batch production, simple structure panels and large thick wall and uneven wall thickness products.

低压灌注适用模具有：树脂模具，ABS模具，铝合金模具
