--- Investment Casting ( Silica Sol Process) ---
Made of stainless steel 304/316 for resistance to corrosion and high temperatures
Investment casting offers unlimited freedom in design and material choices. Typical applications can be found in the automotive, pump and food industry, architecture, and general industrial engineering
1 BENEFITS:
Precise tolerances
Thin walls are possible
Fine surface structure
Complex shapes can be achieved without draft angles
Small marks can be cast very clearly, such as letters or company logos
Suitable for a wide variety of materials
2 TECHNICAL SPECIFICATIONS:
Weight: 0.01 - 50 kg
Casting surface roughness: Ra 0.4 μm
Maximum dimensions: 500 x 500 x 500 mm
Casting wall thickness: ≥ 3 mm, locally 1.5 mm can be reached
Angle tolerances: ± 1°
The geometric tolerances that are required for the function should be specified in the drawing
3 FINISHING OPTIONS:
Pickling and passivation
Electrolytic polishing
Vibra-polishing
Electrolytic zinc plating
Hot-dip galvanizing
Mirror polishing
Dull polishing
| Investment Casting | Die-Casting | Sand-Casting | Lost Foam | Forging |
| 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---- 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)
