See All Posts705 ㅤ typical cosmetic defects of Black PEEK Recently, I started making pens with Black PEEK. I purchased the rods from a South Korean manufacturer. they used German PEEK pellets to produce the rods. Despite my nearly perfect pen making process, when I started machining the material, I noticed several types of common cosmetic defects. 1. white dots (common) 2. tiny metalic dots (rare) 3. small cavities (common) the white dots are the most .. Bock two-tone engraved nib surface treatment test I've recently experimented with surface treatment with bock nib. I've found some new things out 1. engraved features deepens2. hammered texturing seen when magnified (can be altered)3. the slit is affected is well, so i need to take extra care(below I just did it without care, because I didn't know) original (before treatment)lots of scratches can be seen,the entire nib is full of scratches, a.. Dodecagon diamond cigar symmetry developed (PEEK Black) Dodecagon diamond cigar symmetry has been developed (PEEK Black). changes:1. barrel drill depth increased by 3mm (for reducing Con-70 button interference @ end)2. precision Barrel & Cap angle allignment ( ±0.001mm precision for proper angle positioning)3. below pen is non-engraved captop version (engraved ones will be produced as well, although this will take time)*some people wanted non-engrave.. Dodecagon diamond cigar symmetry barrel developed (PEEK Black) Dodecagon diamond cigar symmetry barrel has developed (PEEK Black) it was my first time machining with the peek black material.my first impression is "I sort of experienced hell".although a bit less now, still feeling a bit of burden just by looking at it. well, things have stabilized now, although not perfect.there's still room for improvement, I will keep trying... I will soon complete cap as .. PEEK (Black) 8 types of grip developed PEEK (Black) 8 types of grip have been developed.There were some difficulties, because it was first time handling the new material.however, i was able to overcome them through hard work. now i will move on to developing diamond cigar symmetry (peek tan).thank you. from left:1. one-piece2. one-piece thick arc3. shift arc4. super grip fine5. full arc pipe6. hourglass short7. hourglass arc8. vintag.. difference in color between PEEK Black and conventional black resin Hello, this is Fountain Pen Research.This is the color difference between PEEK black vs conventional black resin (general-purpose plastic such as PP, acrylic (plexiglass), ABS, PC, etc.).Unlike the black color of regular pastics that usually comes to mind when thinking of black,I found that the PEEK black was different.I didn't notice when it was in rod form (unmachined).As I machined the materi.. ㅤ ㅤ ㅤ PEEK (Black) grip section 8 types development inititated Hello, this is Fountain Pen Researcher.While developing PEEK (tan) and Ultem grips,I decided to try the PEEK black material.Although the material color is black,It is somewhat unusual in that it is silvery black. Since the design of the grip section is nib-housingless type,Precision is very important.Normally, 0.01mm precision is optimal.0.02mm precision in the minus direction is not acceptible... Ultem grip sections (8 types) developed. Ultem grip section (8 types) have been developed. I wanted to develop 14 types like Peek, butDue to a shortage of materials, only 8 types were selected and developed.Ultem is a transparent material so you can see the inside.It was more difficult than usual, because internal areas must be machined as clean as possible.Due to the transparent nature of the material, you can see,Depth at which the n.. Ebonite Feed compatible Ultem grip section, development initiated Following the last 14 types of peak grip parts, I also started developing the Ultem grip section (ebonite feeder compatible). Because of limited materials this time, I will limit the types to less than 10. The grip part below is unpolished. This is how it looks like without ink. Below is what it looks like after it's filled. I think the internal appearance will change over time, but this is roug.. ㅤ ㅤ ㅤ What is PEEK ? (Material) PEEK is used in Semiconductor equipments, medical devices, and extreme situations where all other general plastics fail.
