Higher Grade Polishing Method of Plastic Mold

● Polish by oil grinding stone (use kerosene)

● Polish by oil sand paper (use kerosene)

● Finish Polishing by diamond compound (use felt cloth)

#180→#240→#320→#400→#600→#800

#600→#800→#1000→#1200→#1500

#1800→#3000→#8000→#14000

Polish procedure Example

B. Load for polishing should be kept the lowest possible.

C. Foregoing polish should be done prudently.

D. Rust proof measures must be taken in any interruption of jobs.

Scratch remains due tooverload.

Seam and pinhole texture at crossing by less foregoing polish

Pinhole texture by inapropriate rust proof.

Diamond Compound Finish Aluminium Oxide FinishNot Good

Chromium Oxide FinishNot Good

Important points of polishing

1. Each procedure is to be strictly kept.

2. When changing from one number to another, check if there are remained scratches by changing polishing direction. (move 45-90 degrees)

3. When changing numbers, wash and remove last polishing grains completely.

4. Polishing by diamond compound needs to be done in short times. Excessive polish can produce pinholes or orange peel.

5. Avoid alumina and chromium oxide as the polish capabilities are lower than diamond.

6. During long interruption, the object must be protected from the rust.

Remarks:A. For superior polishing use diamond compound. Don't use alumina nor chromium-oxide compound.

Attentive points1. Preparations before welding

A. Form of location to get welded should be made smooth as Figure 1.

B. Cracks and treated surface (nitrided or plated) must be eliminated.

C. Oil, dust, moisture and scale must be removed thoroughly.

A. Welding rod of similar composition as mold is to be used so that welding may not bring about unevenness of mirror �nish or texturing surface.

When the mold is made from HI-PM MAGIC, use welding rod made from HI-PM MAGIC-W. Please refer to special welding material manufacturers or distributors for a kind and the specifications of the

welding rod.

B. In case of using coated electrode, weldling rod should be dried by heating to 250-300℃ before using.

C. For cavity welding, TIG welding should be applied. (TIG: Tungsten Inert Gas)

2. Welding rod

A. Figure 2 shows example of actual welding jobs of representative grades.

B. Tempering should be conducted soon after welding in case of prehardened steel or hardened and tempered steel according to Figure 2.

Tempering is effective to protect mold from crack and to stabilize mirror �nish and surface texture by having uniform hardness and structure.
