■ Partial insertion
       ■ Full insertion
        Avoid using for the exterior parts of mirror finished products
       or transparent items.
POROUS VENT


■ How to Mount
1. Machine the POROUS VENT to match the shape of the molded part. Refer to the left page for treatment after machining.
2. Machine mounting holes and gas release passage into the mold. Be sure to clean with compressed air when finished to make sure that no particles remain, as they may cause clogging.
3. If you need to tap the POROUS VENT during installation, use a strike plate to ensure that the vents do not collapse.
4. When checking the ventilation, apply acetone or alcohol to the surface of the molded product and blow from the opposite side. If bubbles emerge from the entire surface, the product is normal.


■ For Use
· Ventilation recovery processing is necessary after shipment, as all surfaces are non-ventilated.
· Shave the rear surface to secure ventilation by making sure the POROUS VENT walls are not too thick.
· Grinding should be done so as to avoid ventilating the surface, other than for gas release.
· Periodic maintenance is required. Refer to the methods on the left page.
· For cooling, consider using a heat exchanger pipe (WHP) to avoid cooling water flowing directly through the water hole if water leaks. In that case, it is more effective to apply 0.05 to 0.1 mm heat conducting grease (MTJ) between the POROUS VENT and the cooling parts.
· Avoid installation of ejector pins, fixing pins, or inserted items on the POROUS VENT. When gas and air pass through the protruding holes, exhaust and blowing from the gas release holes may become insufficient, causing the released gas and air to return from the protruding holes to the molding surface and cause visual defects on the surface around the pin.
· To prevent rusting, do not store in high-temperature/high-humidity environments or those with fine dust.


■ Features
· A porous metal block insert blank developed for gas release applications.
· The product has a porous structure made from sintered stainless steel (SUS430 equivalent).  
· Effective for improving the molded products surface.
· Gas can be released from any direction, making the product suitable for molded articles
with complex shapes, or for evenly releasing gas from wide-area parts.
· Mechanical machining and laser machining can be performed as necessary for the shape
of the molded product.

POROUS VENT


■ Examples of Molding
  

POROUS VENT

 • Product: Plastic case
• Resin: PP
• Application effects:
Eliminates short shots between
ribs and vertical walls


■ Examples of Machining Conditions
[Table 1] shows an NC milling example while[Table 2] shows a laser machining example.
Check your specific equipment, as other machining methods differ depending on the equipment.

[Table 1] Example of NC milling conditions
Cutting speed (m/min)150
Revolution (rpm)3000
Axial cutting depth (mm)0.1
Radial cutting depth (mm)0.25
Feed (mm/revolution)0.16
[Table 2] Example of laser machining conditions (depth 0.01 mm)
Laser output (W)9
Pulse frequency (kHz)30
Feed speed (mm/sec)800
Wavelength (nm)1064
Offset (mm)0.01
Required tools
· Material: Carbide + AlTiN coating
· Type: 4-flute radius R3
· Applicable work material: Stainless steel (M grade)
Note that if the output is too strong, the elements evaporate from the surface layer and the corrosion resistance decreases.


■ Post-Machining Treatment
• Oil draining
Always drain the oil for discharge machining, wire cutting, NC milling, etc., as impregnation with machining fluid can cause ventilation failure and rust. Refer to [Table 3] for differences in ventilation with and without oil drainage.
• Polished finishing
Finish according to the following procedure.
(1) Polish once with a fine (#800 recommended) oil stone, then rotate 90°and polish a second time.
(2) Polish with an ultra-fine (#1200 recommended) oil stone. (3) Buff using a paste-type polishing agent (0.5 to 1 μm particle size recommended).If necessary, use even finer sandpaper (#2500) to polish further.

Measurement conditions · Test piece size: φ20 x 10 mm · Air pressure: 0.3 Mpa


■ Oil Drainage Method

(1) Air blowing
 
(2) Ultrasonic cleaning
as required)
(3) Hot water washing
 
(4) Drying
 
Make air blowing holes (※) on the side
opposite the molded part surface, to
enable compressed air (factory air equivalent)  
at about 0.5 MPa to be blown for 5 to
10 minutes, prior to wiping off dirt
from the molded part surface with a rag.
※Substitution is possible if the POROUS
VENT has gas release holes.

 
 Use ultrasonic cleaning
for about 30 minutes to 1 hour
while heating to 50 to 60℃,
using a water-soluble detergent        
for metals.




 
 Soak in 50 to 60℃ hot water
for 5 minutes before performing      
(1).
Repeat until the water is no
longer cloudy.




 
 Dry in a drying oven kept
at 150 to 160℃ for 1 to 2 hours.
If a drying oven is unavailable,
perform (1) until moisture is no longer released.
(Approximately 1 to 2 hours)




 

POROUS VENT


■ Maintenance Method

• Daily maintenance
(in molding machinery)
• Periodic maintenance
(in molding machinery)
• Periodic maintenance
(disassembled from molding machinery)
This method eliminates mild resin clogging.
It is recommended at the completion of molding
(or before beginning) every day.
1. Spray alcohol on the surface while still mounted
to the mold and immediately wipe off with a cloth.
Repeat this 1 or 2 times.
2. Wipe the surface with a cloth moistened with alcohol while  
blowing compressed air through the gas release hole.




 
 This method eliminates medium resin clogging.
It is recommended weekly.
1. Spray organic solvent on the surface while still
mounted to the mold and immediately wipe off
with a cloth. Repeat this 1 or 2 times.
2. Wipe the surface with a cloth moistened with
organic solvent while blowing compressed air
through the gas release hole.
Acetone is the recommended organic solvent,
but the most suitable solvent depends on the specific resin.  
Contact the resin manufacturer for details.

 
 This method helps to loosen resin clogs
that cannot be removed by daily or
periodic maintenance.
It is recommended while disassembled
from the molding machinery.
1. Remove the POROUS VENT from the
mold and immerse it in a solvent such as
acetone for 12 to 24 hours.
2. Execute the "Oil draining method" steps
(1), (3) and (4) in order.
