TWSBI VAC 700 update 11/25/2010

http://www.bbs.twsbi.com/viewthread.php?tid=184&page=1

2010/11/25 更新 update
這筆最大的考驗之一是在筆冠與筆夾的製造工藝，本來是想用 diecasting 但效果總是達不到標準。幾經輾轉終於確定筆冠用 CNC 車床加工，筆夾用脫蠟鑄造，兩者都是非常昂貴的工藝，但效果一流。
今天終於拿到筆夾樣品了，還沒精加工但是基材已經是非常棒了。
One of the major difficulty on manufacturying Twsbi Vac 700 is how to fabricate the crown and the clip. We were intend to use die casting method, but result turn out not satisfied. By tring several differenct solutions, it end up that we will use CNC turning to make the crown and clip by casting. Both of these two production process are expensive, but turn out very good result on quality.

TWSBI Diamond Vacuum update 2010/11/14

2010/11/14 更新 update
這一個月的主要事情就是調整些細部尺寸，做小量產前的最後確認工作。
筆夾本來是用成形方式，但表面一直不理想，可能要改用鍛造方式，樣品試做中。
筆蛇模具還在開發中，要到十二月底才會試模，之後才能去德國買筆尖，看來有得等了。
我自己先裝了一支起來用，還是18K金尖的喔。
This passing month mainly working on fine tune final dimensions, get ready for small batch run.
The clip was planning be made by die casting, but we still not happy with the surface finish, so it may be changed to be made by forming. The sample is being processed.
This time we are going to make feeder and feeder housing by ourselves, the tooling won't be ready for test until end of Dec., then I can buy the nib from Bock. It will be some times to wait.
I made a pen for myself for testing, it has real 18K gold nib, cost me a futune to get this nib.

Twsbi Diamond 530 With Gold Nib

Yesterday I got quotation from Bock the 14K gold nib for TWSBI Diamond 530. one in single gold color another in two tone colors.
My cost plus the distribution profit... the end user price will be clost to US$110 per nib for single color and US$130 per nib for two tone model.
Will this price ok? I need to collect at least 300 orders to buy the nibs from Bock.

I am thinking, since the gold nib will bring up the pen price, why not just make an high value version of the pen to make it complete. how about
1. pen with 14k gold nib (single color or two tone?)
2. pen with HIGH VOLUME ink capacity, about 40% more ink
3. pen with aluminium piston mechanism
4. pen with solid brass clip (not the existing stamping parts)
5. pen with improved cap thread for smooth thread in and out
6. pen with metal parts plated with 14K gold or rose gold
Due to the increase in cost, the retail price will go up to about US$280. I don't know if this be fine. I need your comments.

To proceed with the project, I need to collect at least 300 orders. please leave comments in the thread.
If you like to pre-order, write me at speedy@twsbi.com. leave me your name, email, address, want nib (size) or complete pen.
you don't need to pay me anything until pen comes out.

Let me have your comment, see if we can keep the ball rolling.

做了個墨水瓶中蓋模型用來測試，看來效果不錯，大老闆看到了說 "蓋子應該用鋁來做比較漂亮" 所以各位，請把你們的錢包準備好吧，哈哈哈！

We made a middle cap mock up sample for testing the performance, it seemed ok. The big boss (Our President) saw it and said "we should make two caps by aluminium". Now preparing the aluminium sample. Guys, get your wallet ready for that, hahaha!

TWSBI Diamond 530 Piston Seal Leakage Report 2010/07/20

As you may have known that from the first 300 FPN pre-sale pens we found certain pen has seal leaking issue. Here in short are the explanations and solutions.

PISTON VERSION
Piston version 1.3 : The final version before mass production. The design of this version works fine without problem providing the parts dimension is within the spec. All of the early day samples were made by this version.

Piston version 1.3b1 : First mass production batch of version 1.3, but being found some parts are out of spec on sealing ring size.

Piston version 1.3g1 : version 1.3 piston made by harder material to enhance the contact force to the barrel inner wall.

Piston version 1.5 : new version design, sealing rings outer diameter and wall thickness be increased to enhance the contact force to the barrel inner wall. Aiming to eliminate 100% water test procedure during production.

BARREL VERSION
Barrel version 1 : Current version with large inner wall tapering angle to facilitate ejection of core pin during injection molding, so not to leave scratch mark on inner barrel wall.

Barrel version 2 : Future version with reduced inner wall tapering angle, if successful, will made piston design easier and even harder material can be used, this will make piston design and manufacturing easier.

STATUS
Phase 1 : Pen made with piston version 1.3b1 without water leak test.
Minor leak: small sign of ink pass through seal 1, no ink reaches seal 2
Medium leak: larger amount of ink pass through seal 1, did not break through seal 2
Major leak: ink passes through seal 1 and seal 2
Number of pen sold: 300 FPN pre-sale plus roughly 50 others, total around 350 pens. From customers' feedback around 110 leak pen, most of them are minor to medium leak, only 2 or 3 major leak. Twsbi will send replacement parts for repair.

Phase 2 : Pen made with piston version 1.3b1, but with water leak test, without pen tapping against desk top. A few feedback came in reporting still some leakage. Immediately we made house check on 10 completed pen (same batch from 160 speedy carry to LA) ink filled, drop test from 20cm high to desk top(blind cap head down), 1 out of 10 pen has minor leak, I estimate the leak rate can be 10%. If sold pen still found leakage, Twsbi will send replacement part for repair.
Number of pen: 160 pens speedy hand carry to USA plus roughly 20 pens sold by Taipei office. Total around 180 pens.

Phase 3 : Piston version 1.3b1, water leak test, pen tapping against desk top. Few pen left house already. These few days we are still confirming the result.

Phase 4 : Piston version 1.3g1, water leak test, pen tapping against desk top. We anticipate will have no leak issue.

Phase 5 : Piston version 1.5 + barrel version 1. I strongly believe this will permanently prevent seal leaking problem.

Phase 6 : Piston version 1.5 + barrel version 2. We will enter the real test soon, as I heard the barrel version 2 sample came out already. This will be the ultimate solution I wish to see it success.

I feel really sorry for the inconvenience that bring you and hope the solutions will bring back your trust to the TWSBI brand we try to establish.

Sincerely Yours
speedy
