其實(shí)，“手板”并不是一個(gè)新的詞匯，它已經(jīng)存在了很長一段時(shí)期。下面我就來歸納一下濟(jì)南手板制作有哪幾種方法以及它們各自的特點(diǎn)是什么。

In fact, "hand board" is not a new word. It has existed for a long time. Now I'll sum up the methods of making Jinan hand board and their respective characteristics.

激光快速成型。

Laser rapid prototyping.

FDM，是將ABS條用激光燒結(jié)而成，它的特點(diǎn)是物理性能和化學(xué)成分都與ABS一樣，裝配性能好，內(nèi)部結(jié)構(gòu)清晰，但外觀粗糙，適合做結(jié)構(gòu)驗(yàn)證的手板。

FDM, which is made of ABS strips by laser sintering, is characterized by the same physical properties and chemical composition as ABS. It has good assembly performance, clear internal structure, but rough appearance, which is suitable for structural verification.

SLA，是將環(huán)氧樹脂用激光燒結(jié)而成，環(huán)氧樹脂在常溫狀態(tài)下是液態(tài)，裝在SLA機(jī)的箱子里，當(dāng)激光按圖形的結(jié)構(gòu)一層一層掃描時(shí)，激光碰到的地方環(huán)氧樹脂就會由液體變成固體，后，將箱子里多余的液態(tài)環(huán)氧樹脂放掉，就會留下一個(gè)和圖形一模一樣的模型。SLA適合做小件的，但CNC難以加工的手板。

SLA is made of epoxy resin sintered by laser. The epoxy resin is liquid at room temperature and is packed in the box of SLA machine. When the laser scans layer by layer according to the structure of the graph, the epoxy resin will change from liquid to solid where the laser touches. After that, put away the excess liquid epoxy resin in the box, and a model exactly like the graph will be left. SLA is suitable for making small pieces, but CNC is difficult to process.

SLS，由SLA發(fā)展而來，它除了兼有SLA的功能外，還可以燒結(jié)金屬粉末（如鋁粉銅粉不銹鋼粉等），制作手板的成本比SLA的高。

SLS, developed from SLA, not only has the function of SLA, but also can sinter metal powder (such as aluminum powder, copper powder, stainless steel powder, etc.), and the cost of making hand board is higher than that of SLA.

CNC加工。

CNC processing.

CNC手板模型是綜合計(jì)算機(jī)輔助設(shè)計(jì)（CAD）計(jì)算機(jī)輔助制造（CAM）計(jì)算機(jī)數(shù)字控制(CNC)等技術(shù)，把計(jì)算機(jī)上構(gòu)成的三維數(shù)據(jù)模型，由整塊材料切削挖掘加工而成。它的特點(diǎn)是加工速度快成本低，可以達(dá)到很高的加工精度。

CNC prototype is an advanced technology that integrates computer aided design (CAD), computer aided manufacturing (CAM), computer digital control (CNC) and other advanced technologies. The three-dimensional data model formed on the computer is formed by cutting and mining the whole material. It is characterized by high processing speed, low cost and high processing accuracy.

而且材料的選擇范圍廣，可以保證手板模型的材料和批量生產(chǎn)零件材料的一致性。手板的真實(shí)感強(qiáng)，表面質(zhì)量可以達(dá)到很高的水平，在進(jìn)行打磨拋光噴砂噴漆絲印UV電鍍等后續(xù)加工后，制作效果完全可以同模具生產(chǎn)的產(chǎn)品相媲美，甚更高。由于CNC加工需要一個(gè)一個(gè)地做，所以它適合做1-5個(gè)的批量。

Moreover, the selection of materials is wide, which can ensure the consistency between the materials of the prototype and the materials of mass-produced parts. The hand board has a strong sense of reality, and the surface quality can reach a high level. After subsequent processing such as grinding, polishing, sandblasting, painting, silk screen printing, UV electroplating, the production effect can be completely comparable to or even higher than the products produced by the mold. Because CNC processing needs to be done one by one, it is suitable for 1-5 batches.

真空復(fù)模（硅膠復(fù)模）。

Vacuum mold (silicone mold).

其流程是先用母板做一個(gè)硅膠模，然后再倒入液態(tài)的環(huán)氧樹指（如PU），再加熱讓其固化，后就可從硅膠模中取出一個(gè)和母板一模一樣的手板（模型）。 但硅膠模是軟模，其手板（模型）的尺寸精度不高。并且所用材料是環(huán)氧樹脂，不是真正的塑料。它適合做5-50個(gè)的批量。

The process is to make a silica gel mold with the motherboard, then pour liquid epoxy tree fingers (such as PU), and then heat it to cure, and then take out a hand board (model) that is exactly the same as the motherboard from the silica gel mold. But the silica gel mold is a soft mold, and the dimensional accuracy of its hand plate (model) is not high. And the material used is epoxy resin, not real plastic. It is suitable for 5-50 batches.

低壓灌注。

Low pressure perfusion.

又名低壓反應(yīng)注射成型（RIM），是應(yīng)用于快速模制品生產(chǎn)的一項(xiàng)新工藝，它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)，通過材料的聚合交聯(lián)固化等化學(xué)和物理過程形成制品。具有效率高生產(chǎn)周期短過程簡單成本低的優(yōu)點(diǎn)。適用于產(chǎn)品開發(fā)過程中的小批量試制，以及小批量生產(chǎn)的結(jié)構(gòu)較簡單的覆蓋件和大型厚壁及不均勻壁厚制品的生產(chǎn)，低壓灌注適合做5-50個(gè)的批量。

Also known as low-pressure reaction injection molding (RIM), it is a new process applied to the production of rapid molding products. After mixing the two-component polyurethane materials, it is injected into the rapid mold at room temperature and low pressure, and the products are formed through chemical and physical processes such as polymerization, crosslinking and curing of the materials. It has the advantages of high efficiency, short production cycle, simple process 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. Low pressure pouring is suitable for 5-50 batches.

快速模具（簡易模具）。

Rapid tooling (simple tooling).

它是將正式模具簡化結(jié)構(gòu)之后，完全按正式模具那樣來做模，然后上塑膠機(jī)注塑加工，再用CNC加工，以達(dá)到圖紙要求。簡易模具是將模具工藝和機(jī)加工工藝有機(jī)的結(jié)合。它的優(yōu)點(diǎn)是完全可以按設(shè)計(jì)的要求選用材料，如ABS-V0，PC+ABS，PA66+30%GF，POM+30%GF等，也完全按設(shè)計(jì)的要求注塑加工。它的批量適合于50-5000，非常適合產(chǎn)品小批量的試產(chǎn)，是小批量生產(chǎn)理想的方式。

It is to simplify the structure of the formal mold, make the mold completely according to the formal mold, then put it on the plastic machine for injection molding, and then process it with CNC to meet the requirements of the drawing. Simple mold is an organic combination of mold technology and machining technology. Its advantage is that materials can be selected according to the design requirements, such as abs-v0, pc+abs, pa66+30%gf, pom+30%gf, etc., and injection molding processing can also be carried out according to the design requirements. Its batch is suitable for 50-5000, which is very suitable for small batch trial production of products. It is an ideal way for small batch production.

根據(jù)工藝設(shè)備的不同，手板制作可以分為激光快速成型（FDMSLASLS），CNC加工，真空復(fù)模（硅膠復(fù)模），快速模具（簡易模具）和低壓灌注等方法。以上內(nèi)容希望能給您幫助，更多內(nèi)容就來網(wǎng)站http://www.metferro.com咨詢了解吧。
