Product catalog summary
Overview of Closed Molding:
Closed molding is a manufacturing method that offers consistent and repeatable production of high-quality parts with reduced emissions and waste compared to open molding. The process involves laying fiber reinforcements into a base mold, closing and sealing the mold, injecting resin, and then curing and removing the part.

Types of Closed Molding:
  • Resin Transfer Molding (RTM): Utilizes a composite mold reinforced by metal for high-volume production.
  • Light Resin Transfer Molding (LRTM): Involves a rigid mold and semi-rigid counter mold sealed by vacuum, with resin injected using a machine.
  • Resin Infusion Process: Suitable for large parts and higher glass content, featuring a single injection port and silicone resin channel network.
  • Flex Molding Process: Developed by MVP, uses one rigid and one flexible mold half, such as a plastic bag or silicone membrane.
  • Fast Flow LRTM: Combines Flex Molding and LRTM for faster injection times and larger parts production.

Closed Molding Equipment:
  • 1:1 Patriot Silicone System: Designed for mixing and dispensing 1:1 volumetric materials, ideal for reusable membranes.
  • Patriot Innovator RTM Systems: For injecting resins and catalysts at controlled pressures, featuring automated controls and PLC options for precision.

Accessories and Components:
  • Various injection valves, feedline control modules, and pneumatic sensors.
  • Universal adapters, seals, and connectors for different molding processes.
  • Catchpots and seal profiles for vacuum and resin flow management.

MAGNUM VENUS PRODUCTS Closed MoldingComprehesive products, services and training to support a variety of closedmolding methods Closed molding is a consistent and repeatable manufacturing method enabling higher quality parts, faster production, reduced emissions, and with less waste compared to open molding. With this method, fiber reinforcements are laid into the base mold, the mold is closed and sealed, and the resin is injected into the closed mold cavity. Once the resin has cured, the mold is opened and the part is removed.
