Magnum Venus Products (MVP) says that it has developed a new process for closed molding which it says could increase part production by decreasing injection times.
The company’s Fast Flow light resin transfer molding (LRTM), is a combination of the company’s flex molding process and LRTM and uses collapsible resin channels for a faster resin flow.
When using a traditional LRTM mold, resin flow speed can be dependent on the distance between the resin channel and center of the part during injection, MVP says. Utilizing the same silicone collapsible resin channels developed for its flex molding process, the new technology reportedly allows channels to be installed closer together to decrease the resin flow distance and speed up injection times. MVP said that it can inject a 50 ft2 part in under four minutes using only one injection port, while also delivering a improved back side surface aspect equivalent to traditional LRTM. By injecting the resin from the center to the border, the part demolds with a finished look and no visible resin channels, wasted materials or excess resin.
