Why is precision casting necessary?
Investment casting is an effective process that has been used by craftsmen and manufacturers for more than 5,000 years. Compared with other processes, its many advantages and advantages make it very suitable for many industries and applications.

The following are the eight main advantages of PPCP precision castings:
1. Flexible design
Investment casting can adapt to almost all design features and use a variety of alloys.

2. Alloy area
Precision casting can use hundreds of different alloys to achieve cost efficiency and meet special requirements. The near-net process greatly reduces the need for finishing, which can use harder alloys in beneficial situations.

3. Part consistency
The wax mold used in investment casting is always produced using the same tool. This ensures that the parts are consistent and meet specifications and tolerances.

4. Surface quality
The part is taken directly from the mold and has a very good surface finish, usually about 125 RMS.

5. Details and accuracy
Investment casting can achieve excellent detail and accuracy-in the range of +/- 0.005 inches per inch. Details and functions require little extra processing.

6. Reduce production costs
Precision cast almost net shape parts require less processing. Tools are cheaper; and the life of these tools is longer than other processes.

7. Reduce waste
The precision cast, almost mesh-like shape requires little processing, thereby minimizing material waste.

8. Reduce processing time
Using the precision casting process from the initial concept to production takes less time than other production options. Products can enter the market earlier, and companies can better respond to changing market demands.
