真空复模和低压灌注是手板加工的常见方法，两者的原理表面看起来较为相似，但其实两者还是有一定区别的，下面给大家分析真空复模和低压灌注两种手板加工方式的区别。

Vacuum molding and low-pressure pouring are common methods of hand board processing. Their principles look similar on the surface, but in fact there are some differences between them. Next, we will analyze the differences between vacuum molding and low-pressure pouring.

真空复模

Vacuum compound mold

真空复模是利用原有的样板，在真空状态下制作出硅胶模具，并在真空状态下采用PU材料进行浇注，从而克隆出与原样板相同的复制件的一种较为常见的加工方式。其主要用于塑胶手板小批量的定制，一般在几十个到上百个的塑胶手板，如果采用这种方式加工是比较划算的。

Vacuum replica is a common processing method that uses the original template to make silica gel mold in vacuum, and uses PU material to pour in vacuum, so as to clone the same replica as the original template. It is mainly used for small batch customization of plastic hand boards, generally in dozens to hundreds of plastic hand boards. If this method is adopted, it is more cost-effective.

真空复模产品材料性能可模拟大部分现有工程材料性能，常见材料有国产PU、进口PU、透明PU、软PU、赛钢、ABS、PP、PC耐高温的ABS等，同时可复制出透明件如PC，有机玻璃等，热塑性弹性体TPR、TPR、TPU等以及各种软性材料如硅胶、橡胶等。

The material performance of vacuum replica products can simulate the performance of most existing engineering materials. Common materials include domestic PU, imported Pu, transparent Pu, soft PU, saigang, ABS, PP, PC high temperature resistant ABS, etc. at the same time, transparent parts such as PC, plexiglass, thermoplastic elastomer TPR, TPR, TPU, etc. and various soft materials such as silica gel, rubber, etc. can be copied.

低压灌注

Low pressure perfusion

低压灌注是应用于快速模具的一项新工艺，主要是将双组份聚氨酯材料经混合后，在常温、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。具有效率高、生产周期短、成本低的优点。适用于产品开发过程中的小批量试制，以及小批量生产的、结构较为简单的覆盖件和大型厚壁及不均匀壁厚制品的生产。

Low pressure pouring is a new process applied to rapid tooling, which is mainly to inject two-component polyurethane materials into the rapid tooling at room temperature and low pressure after mixing, and form products through chemical and physical processes such as polymerization, crosslinking and curing of materials. It has the advantages of high efficiency, short production cycle and low cost. It is suitable for small batch trial production in the process of product development, as well as the production of panel parts with simple structure and large thick wall and uneven wall thickness products in small batch production.

低压灌注可以灌注厚壁产品，并且壁厚可以是不均匀的产品，正常灌注壁厚（5-6mm）厚可以做到30mm左右，模具采用的材质很多（有铝模，树脂模，塑胶模、石膏模等），灌注材料选择较多，有进口材料，有国产材料，有接近ABS的材料，有接近pp的材料。

Low pressure pouring can pour thick wall products, and the wall thickness can be uneven products. The normal pouring wall thickness (5-6mm) can be about 30mm. There are many materials used in the mold (aluminum mold, resin mold, plastic mold, gypsum mold, etc.). There are many pouring materials, including imported materials, domestic materials, materials close to ABS, and materials close to PP.

济南手板小编进行区别总结：真空复模主要是用来小批量复制体积小的手板（如ABS、PC、亚克力手板等），而低压灌注是用来复制体积大的手板，如汽车保险杠、医疗仪器机箱壳体、仪器面板手板等。

Jinan hand board editor makes a distinction and summary: Vacuum replica is mainly used to copy small hand boards (such as ABS, PC, acrylic hand boards, etc.) in small batches, while low-pressure perfusion is used to copy large hand boards, such as car bumpers, medical instrument chassis shells, instrument panel hand boards, etc.
