真空復(fù)模和低壓灌注是手板加工的常見(jiàn)方法，兩者的原理表面看起來(lái)較為相似，但其實(shí)兩者還是有一定區(qū)別的，下面給大家分析真空復(fù)模和低壓灌注兩種手板加工方式的區(qū)別。

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.

真空復(fù)模

Vacuum compound mold

真空復(fù)模是利用原有的樣板，在真空狀態(tài)下制作出硅膠模具，并在真空狀態(tài)下采用PU材料進(jìn)行澆注，從而克隆出與原樣板相同的復(fù)制件的一種較為常見(jiàn)的加工方式。其主要用于塑膠手板小批量的定制，一般在幾十個(gè)到上百個(gè)的塑膠手板，如果采用這種方式加工是比較劃算的。

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.

真空復(fù)模產(chǎn)品材料性能可模擬大部分現(xiàn)有工程材料性能，常見(jiàn)材料有國(guó)產(chǎn)PU、進(jìn)口PU、透明PU、軟PU、賽鋼、ABS、PP、PC耐高溫的ABS等，同時(shí)可復(fù)制出透明件如PC，有機(jī)玻璃等，熱塑性彈性體TPR、TPR、TPU等以及各種軟性材料如硅膠、橡膠等。

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.

低壓灌注

Low pressure perfusion

低壓灌注是應(yīng)用于快速模具的一項(xiàng)新工藝，主要是將雙組份聚氨酯材料經(jīng)混合后，在常溫、低壓環(huán)境下注入快速模具內(nèi)，通過(guò)材料的聚合、交聯(lián)、固化等化學(xué)和物理過(guò)程形成制品。具有效率高、生產(chǎn)周期短、成本低的優(yōu)點(diǎn)。適用于產(chǎn)品開(kāi)發(fā)過(guò)程中的小批量試制，以及小批量生產(chǎn)的、結(jié)構(gòu)較為簡(jiǎn)單的覆蓋件和大型厚壁及不均勻壁厚制品的生產(chǎn)。

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.

低壓灌注可以灌注厚壁產(chǎn)品，并且壁厚可以是不均勻的產(chǎn)品，正常灌注壁厚（5-6mm）厚可以做到30mm左右，模具采用的材質(zhì)很多（有鋁模，樹(shù)脂模，塑膠模、石膏模等），灌注材料選擇較多，有進(jìn)口材料，有國(guó)產(chǎn)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.

濟(jì)南手板小編進(jìn)行區(qū)別總結(jié)：真空復(fù)模主要是用來(lái)小批量復(fù)制體積小的手板（如ABS、PC、亞克力手板等），而低壓灌注是用來(lái)復(fù)制體積大的手板，如汽車(chē)保險(xiǎn)杠、醫(yī)療儀器機(jī)箱殼體、儀器面板手板等。

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.

真空復(fù)模和低壓灌注兩種手板加工方式的區(qū)別就是這樣了，您可以作為參考使用，在選擇加工方式時(shí)依據(jù)自己的實(shí)際情況來(lái)定，更多相關(guān)內(nèi)容的了解就來(lái)我們網(wǎng)站http://www.debangboya.com咨詢(xún)吧。
