| 1. Low-volume production runs are cheaper as tooling is less costly. | 1. Tooling costs are far higher, only cost-effective for very large volumes. | 1. High cost in large production runs. | 1. Processing costs are higher due to scrap costs, shell building, and pattern handling. | 1. Tooling costs are far higher. |
| 2. Can produce much more complex designs, incorporating design features such as logos. | 2. The parts produced are usually less complex. | 2. Parts are less complex. | 2. Surface finish is typical of lower quality. | 2. Tooling must be replaced quite frequently due to wear. |
| 3. Parts require little machining after finishing. | 3. More material limitations, can't be used for ferrous alloys. | 3. Lower dimensional accuracy. | 3. Tooling cost is increased. | 3. Lower dimensional accuracy. |
| 4. Excellent surface finishes can be achieved. | 4. Surface finishes are usually lower quality than Investment casting and require additional processing. | 4. Surface finish requires additional work. | 4. Parts require little machining after finishing. | 4. Extremely limited component complexity. |

--- Quality Control ---
Junya work closely from concept to finished product
1) Checking the raw material after they reach our factory----Â Incoming quality control (IQC) 2) Checking the details before the production line operated 3) Have a full inspection and routing inspection during mass production---- In-process quality control (IPQC) 4) Checking the goods after they are finished---- Final quality control (FQC) 5) Checking the goods after they are finished---- Outgoing quality control (OQC)* Our wax casting product is processed by 79 steps with high standards and 100% inspection. Along with the power of our advanced machine, quality is something you do not need to worry about.
