Description

The SRTM60083 Vanishing Resin Channel creates resin flow channels that will collapse after the injection. It eliminates resin-rich flow channels on the back side that can also "shadow" the "A" finish side, providing an accelerated resin fill. The channels can also sequence flow paths leading from one primary channel feed line, which is most useful on large moldings.

The SRTM60083 Vanishing Flow Channel is to be installed upon the semi-cured SRTM600600 series silicone rubber while making an SRTM Silicone reusable membrane (Bag). 

Application:

1 In the process of applying the SRTM silicone rubber the membrane thickness is applied consistently along the path of each of the vanishing resin runner channels to a membrane thickness of not greater than 3mm ( 1/8" ). There is to be no reinforcement fabric in the nominal membrane along the channel except at the location of the injection port. At the port location, prior to applying the silicone rubber, there are small runners typically not more than 2 to 3 mm high and wide ( ~ 1/8"  square ) that will extend out from the injection port base normally ~35 mm ( 1 1/2" ) to give the resin a permanent non collapsing resin runner that will remain a witness line on the "B" side of part. The injection port can be located in-line with the flow channel or off to the side of the flow channel. 

The nominal RTV silicone membrane will be sprayed and carefully monitored by a visual indication of the thickness not to exceed ( 3mm / 1/8" ) along the path the channel will be bonded on top of the membrane. 

Note: This is a critical factor in the application of the vanishing resin channel to allow for the needed flexibility and stretch to be an effective resin flow path in the injection process. 

How the Vanishing Flow Channel Works

 

1. The SRTM60083 Vanishing Channel is bonded to the semi-cured membrane along the designated flow path. WIth the SRTM60089 Port already bonded in place with at least one layer of reinforcement fabric over the base of the injection port. The injection port can be installed in-line with the channel
