Ch24. 拆招CMF設計談F開頭的那個字

CMF為Color Material and Finishing,譯為色彩、材質、及表面處理工藝,屬於 工業設計 旗下重要的一環。Unwrap CMF( 彩材拆拆 )將圍繞著這個主題,以淺而易懂的小故事拆解 CMF設計師 的日常。

CMF的C是色彩(Color),M是材質(Material),這兩者都容易理解,但F到底代表的是什麼呢?

就如同其動詞型態代表的「結束、完成」, finishing 意指「最後一道工序」,也就是最表層的效果。然而,表層的效果也是五花八門: 光澤紋理 、甚至 手感 等皆可被含括在finishing的範圍中。

第21章曾簡單的聊過紋理,已知紋理有多種工藝實現方式(模內裝飾技術 、水轉印 、印刷 等)。其實,單單是光澤的光啞對比,在不同材質上就有不一樣的工藝處理製程。

在免噴塗的塑膠上,可以經由模具的加工,利用咬花紋的粗細(亦稱做火花紋,英譯VDI)及拋光直接在模具中做出光啞對比的效果。這裡稍作補充,VDI其實是德國工程師協會(Verein Deutscher Ingenieure)的縮寫,但在CMF及模具行業被泛指為模具上咬花紋的粗細度。

如果使用鋁之類的金屬材質,那 噴砂 是常見的磨砂霧面工藝;而經由CNC加工、鑽切等工藝,則可實現類高光的效果。

若是噴塗,高光和霧面的面漆大家應該都不陌生了。高光面漆流動快,容易在邊緣產生積漆的肥邊;半光不啞又會產生橘皮(可複習第1章滅火器的肥邊和橘皮照片),所以在選定表面效果之後,還需要密切跟進工廠的打樣,確保製程工序已因應光澤度做過調適。

甚至還可以在面漆中添加成分,使其摸起來像橡膠或嬰兒膚質(baby skin),我們將之統稱為手感漆(soft-touch)。另外亦可在油漆中摻入不同成份,帶出變色珠光、裂紋等各種琳瑯滿目的表面處理效果。

𝐓𝐡𝐞 𝐄𝐧𝐝. 不然這篇寫不完了😆

CMF is short for Color Material and Finishing. It is a specific field within industrial design. In the future, Unwrap CMF will write about little stories of CMF Design for those who are interested in learning more about the field.

C is for color, M is for material, these are given. But what does “F” really mean?

As its verb suggests, finishing refers to the very last process, which is the surface treatment: gloss, pattern, texture, and even tactility can be included in the range of finishing.

In Chapter 21, we briefly talked about patterns, which can be realized in productions via IMD, water-transfer, printing, and many more. In fact, just the gloss level alone, can be realized with a range of manufacturing processes, especially on different types of materials.

On uncoated plastic, via the fineness of the VDI texture and polishing, a contrasting finishing can be brought out directly in the tooling. 𝐒𝐢𝐝𝐞 𝐧𝐨𝐭𝐞𝐬: VDI is short for Verein Deutscher Ingenieure (Association of German Engineers), but it is generally referred to the fineness of the mold texture by CMF and tooling industry.

With metal materials such as aluminum, sandblasting is a common method to add a satin surface. In contrast, a high-gloss finishing can be made via CNC diamond-cut process.

I’m sure everyone is already familiar with paint gloss. High-gloss paint flows fast and tends to produce fat edges where paint is gathered. Semi-gloss paint tends to produce orange-peel (see Chapter 1 to find photos of both). Therefore, after defining the gloss level, it is necessary to work closely with the suppliers throughout trials to ensure the manufacturing processes have been optimized.

In addition, additive can be added in paint topcoat to make it feel like rubber or baby skin, which are categorized as “soft-touch paint”. There are also other types of additives that can bring out a variety of surface effects such as color-changing pearls or leather-like cracking texture.

That’s 𝐓𝐡𝐞 𝐄𝐧𝐝 for now, before running out of Instagram word cap 😆
