| ■ Precautions for Processing | ||
| (1) | The four ⒶⒷ sides can be polished. Abrasive residue from polishing entering the vent area may cause blockage |
|
| (2) | Wire cutting and electric discharge are the only available processing for the upper and lower surfaces of the slit. This product is made of layered stainless steel material about 0.2 mm thick. Make sure the surface roughness is about 10 μm under the electric conditions for thin plates, since large sparks may be produced and clogging may occur under the conditions for thick plates. | |
| ■ How to Mount | ||
| (1) | Square up four surfaces Since right angles are not provided on the product sides (Fig. 1 ⒶⒷ surfaces), perform squaring by grinding. We recommend using additional processing KD. |
|
| (2) | Processing of upper and lower slit surfaces (as needed) To adjust the shape to match the product part, perform wire cutting or electric discharge on the Fig. 1 upper and lower slit surfaces. | |
| (3) | Assembling into cavity core Assembly methods include 1) press-fitting and 2) flange + spacer. For the flange + spacer method, provide flange processing according to Fig. 2. Milling, wire cutting or grindstone polishing are possible. When specifying additional machining FC, the product will be delivered with flange processing provided to the specified dimensions. | |

■ Maintenance Method | ||
| When the gas release effect weakens, wash with an organic solvent, etc. In addition, a vacuum generator (M-VCL, M-VCLH) can be used in combination to support the gas release. | ||
■ Features | ||
This part is used for gas release, with a fine slit structure made possible by diffusion
bonding technology.
It is installed to release gas and residual air from the slit part (approx. 0.012 mm).
With multiple slits, it demonstrates high gas releasing performance.

With multiple slits, it demonstrates high gas releasing performance.
| Vent is wide enough to handle final filling part misalignment as well | |
| Since slits are arranged on the entire product part contact surface, it can also handle deviation of the final filling position due to minute fluctuations in molding conditions and differences in the resin lot. This greatly increases the efficiency of positioning during designing and condition setting during molding. | ||
| ||
| Linear passage makes resin clogging unlikely | |
| Since the gas passage is linear, clogging of resin due to solidification of gas in the middle of the passage is reduced. This reduces downtime due to maintenance and contributes to the efficiency of the molding cycle. | ||
| ||
| Equivalent or higher gas release effect at low cost | |
The installation costs are lower compared to other methods when releasing gas from the same area, and since the aperture ratio (※) is high, it exhibits high gas releasing performance. |
