The knowledgeable mold polisher may observe the finishing routine demonstrated below to attain the preferred finishing look in the most economical way:
- Benchwork
- Stone Finish
- Coarse Diamond Finish
- Fine Diamond Finish
- Buffing
Benching is an approach of working on the piece for later polishing. AII bench work ought to be accomplished before starting to polish. Benching might be just to make a radius or as complex as discing, milling, and integrating converging areas and after that flatting by flap wheels or rough emery. If much benching is necessary ,deep cutter spots and stepped areas needs to be removed initially, then the radii needs to be mounted or enhanced. A polisher may frequently operate from detail to widen regions.
Stone finishing refines most areas of the work piece. Once each stage of stoning is accomplished, those areas should have the identical standard exterior face. Stone finishing is carried out by profiler. To obtain the finest finishing look with minimal time, stoning should constantly be carried out in the subsequent order, starting from the deepest region .
- Stoning each edges and feature like radii.
- stoning each horizontal areas.
- Stoning each vertical areas.
- Each areas stoning ought to be accomplished before adjusting to a refined grit.
Rough diamonding eliminates the stone spots and then starts the shinning procedure. AII tools and laps employed for mirror finish needs to be dedicated to every class of diamond compound. Get started with rough diamonding, any areas needs more than a #600 stone finish. A 450 to 650 emory finish is certainly the greatest. Diamond stoning stages tend to be the identical . A mold polisher may stone the inward feature initially and do next job to a larger areas. The largest achievable brush will be employed. Commence rough diamonding by #15 compound. In most diamond stoning process, the primary factor is to apply the least pressure plus a brush with velocity of 2000 to 3000 Revoltions per minute.
Fine diamond finish can be carried out with 1 to 3 stages. The quantity depends on the ultimate finishing look needed. Fine diamonding is the identical concerning coarse diamonding. Commence the fine diamond finish by using #6 level compound. In case needed, the 2nd stage is carried out by #3 level compound. To have an optical superior finishing look, a third action can be carried out utilizing #1 level compound. Each time ,the level of diamond compound is usually improved, it is vital that any areas are without any the previous compound.
Buffing is normally the ultimate stage. It is performed both by machine and by person. Buffing starts once you have accomplished your final diamonding stage. If buffing, a mold polisher may commence from the identical level of mirror as the final brushing stages. Approaches are the identical as diamonding; conducted from feature to huge areas ,utilizing the biggest buff available. Light pressure plus a velocity of 4000 to 6000 Revoltions per minute may make the finest results. If mechanical buffing is finished, hand rubbing from a cotton ball may get rid of all swirl spots remaining after the buffing operation.

The procedures during the texturing operation are introduced below, and on the next pages. These procedures are well-known knowledge in the texturing industry, but every business keeps secured tips for their specified techniques.
- Check
- Clean
- Cover up
- Acidize
Check
The initial stage throughout the texturing operation is to eyesight examine every exterior face on the mold core and cavity. This will be completed to guarantee any cutter spots are eliminated, converging areas will be combined effectively, and the expected finishing look is definitely uniform.
CleanAppropriate cleaning ensures an excellent, consistent texture. Cleaning eliminates all grit and grease on the surfaces which need texture. Just the grease remaining from a fingerprint might damage the consistency of the cover up and acid shower.
Masking(covering up)
Masking determines the specific model remaining on the steel. Coming from wooden grains to natural leather to pebbly, you can find numerous styles could be choosed. Appropriate masking demands to you to be patient and talent. The mask should not be wrinkly or pulled. Caution ought to be taken once entering corners and within fitting edges of 2 areas of masking materials. All flaws would need the plastic mold to be polished again. 
Acid bathThe acid bath is usually an etching approach. You can find 2 aspects which determine the results of the acid bath:
- Variety of materials need texture; ferrous/non-ferrous, chrome material, carbon material. These may decide the kind of acid to be utilized.
- Deepness of the texture decides the time invested in the acid shower. It should be mentioned the acid not merely burns downwards, and also laterally
Once the piece is soaked inside the acid bath after the determined time, it will be instantly sunken in a specific solution to cease the burning activity. As soon as the acid solution is neutralized, the component will be dehydrated and the covering materials will be eliminated. A second eyesight inspection will be carried out at this stage to examine the uniformity of the piece.
