Main arm "B" lifts parts from the mold area and traverses to an open cooling fixture
Once the parts are formed, they are transferred to a cooling fixture
and indexed along mesh belts until they are brought down to handling temperature.
Other news from the conference includes an easy way to monitor screw and barrel wear without extended downtime and an innovative cooling fixture
that significantly reduces cycle time.
Longer mold-cooling time or use of a secondary cooling fixture
are possible solutions, but they add cost to the process.
This permits simultaneous molding, cooling and ejection, for a significant productivity increase without need for a robot or cooling fixture
Average cycle time range for processing RTM body panels at Aero Detroit (not including the preforming cycle) is 14-17 min, which includes the time to open the clamp, manually insert the preform, close the clamp, inject resin, hold and cure, open the clamp, manually remove the part, loosen and remove flash with compressed-air guns, and place the part in a cooling fixture
When setting up the machine for a new run, Griep said it is important to have the mold and process program ready to be installed and all auxiliary equipment such as cooling fixtures
in place, so that the changeover can happen very quickly.
Holtzbergs groundbreaking program will leverage Solvays advanced polymer technologies to develop up to ten engine parts, including cam sprockets, fuel system components, O-Rings, water cooling fixtures
, throttle body parts and other high-performance components.
Use shell core cooling fixtures
to maintain dimensional accuracy
We increase the cooling time to try to fixture the part in the mold, and/or we're forced to use post-mold cooling fixtures
