一般客戶有比較大產品需要做小批量生產可產品數量都沒有達到上萬個，這時候客戶為了節約成本就會選用低壓灌注的方式來制作，下面來講講低壓灌注模型工作原理用途等內容吧

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

低壓灌注是一種快速模具制品生產的新工藝，它相對注塑來說成本較低，由于它的產品都是 整體成型出來的，所以低壓灌注生產出來的產品具有縮水和變形較小，有效率高、生產周期短、過程簡單、成本低的優點，制作的產品強度也高。在當下的行業情況下來說客戶的需求是越來越大。

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.

低壓灌注成型的工作原理：將預先配制好的多組份聚氨酯材料經計量泵以一定的配比送入混合頭經混合后，在低壓環境下注入快速模具內，通過材料的聚合、交聯、固化等化學和物理過程形成制品，注入量由泵的單位吐出量和注射時間來控制。

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.

低壓灌注的用途：山東快速成型廠家認為其適用于產品開發過程中的小批量試制，以及小批量生產的、結構較簡單的覆蓋件和大型厚壁及不均勻壁厚制品的生產。

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.

低壓灌注適用模具有：樹脂模具，ABS模具，鋁合金模具
