SPI抛光规范(SPI A1-SPI D3)∙ An SPI A-1 Diamond Finish is a specialty of Bales Mold Service.We use it to produce the finest finish on molds, producing highly visible or lens quality parts. The SPI A-2 is the most widely used diamond finish, providing good release and good visual parts. An SPI A-3 is a fine choice for release where a high gloss appearance is not required. All diamond finishes work well with chrome andnickel.∙Paper Finishes, SPI B-1 to B-3– Next to diamond polishing, paper finishes are the second most refined finishes available. Paperfinishes produce a slightly reflective or glossy shine and very good release. They are often recommended for products that do not requirea big decorative or visual impact.∙Stone Finishes, SPI C-1 to C-3– The most economical finish, stone finishes are also the first step in the process of creating both the paper and diamond finishes. Stone finishes provide good release but very little gloss to the plastic part. This is a good choice for strictly functional molded parts where aesthetics are of no importance.∙Blast Finishes, SPI D-1 to D-3– When done properly, blasted finishes can produce some of the most interesting stipples andtextures on mold surfaces. From a fine satin texture with varied degrees of gloss to a flat, no-gloss coarse stipple, Bales has the blast media to produce the proper finish for you. Blast finishesare also an excellent way to camouflage weld repairs and slight imperfections.SpecificationsTypes of Finishes Current SPIFinish NumbersDescription andPrevious Finish NumbersRoughnessComparisonR.A.Diamond #3 Diamond Buff A1is comparable to #1 0-1 #6 Diamond Buff A2is slightly finer than#21-2 #15 Diamond Buff A3has more imperfectionsthan2-3Paper 600 Grit B1is finer than#32-3 400 Grit B2is slightly finer than 4-5 320 Grit B3is comparable to 9-10Stone 600 Stone C1is finer than#410-12 400 Stone C2is slightly finer than 25-28 320 Stone C3is comparable to 38-42Dry Blasted #11 Glass Bead D1is finer than#510-12 240 Aluminum OxideBlastD2is comparable to 26-32 #24 Aluminum OxideBlastD3is a little more coarsethan190-230。
SPI-SPE_抛光标准
拋光標准
一. 試模前必須檢查打光是否完全符合要求或是否全部完成.<br> 二. 火花紋地方是否正确及是否可以出模.<br>
三. 所有鏡面打光,鋼材必須用ASSAB 136,見硬52-54HKC工件表面光洁度按照下列新標准

1. 見硬方法
- 用真空熱處理.
- 見硬時在熱處理通知表必須注明:
1. 德勝2083ESR
2. 硬度52-54HRC
3. 高溫淬火+2次低溫回火
4. 大陸的加工厂可以在德勝熱處理;香港加工厂可以繼續用好百利.
1. 加工方法
用EDM火花電蝕加工,但需注意以下几點:
- 用低電流加工.因為高電流粗加工容易留下凹穴,打光時留下深孔. - EDM只适用日本火花机加工,因台灣机火花紋深淺不一,會留下深孔.以因拋光鑽石膏后才看到 "孔",如有凹孔重新打光需由#320開始,會浪費大量工時.。
