How to Use Resin Infusion Process to Form Products

 

Step 1: Prepare Materials

 

 

Before using the vacuum infusion molding process, we first prepare the required auxiliary materials. If we prepare them during the production process, it will be very troublesome. After all the materials are prepared, we can start the operation.

 

Step 2: Mold Preparation

 

 

This step is critical. When preparing the mold, many factors need to be considered, such as the air tightness of the mold, surface finish, cleanliness, defects, width of the mold flange, etc. The mold I chose is an epoxy system mold. Because the infusion molding process is cured at room temperature, it does not need to be cured at high temperature. This mold can withstand temperatures of 50°~60°

 

We need to apply 4-6 times of release agent to a new mold. I chose Easycomposites’ Easy-lease chemical release agent. This release agent has a very good release effect and is semi-permanent, which means that you don’t need to wipe the release agent again next time you make a product.

 

Step 3, Bonding Sealing Tape

 

 

After the release agent is wiped off, we can glue the sealing tape on the flange edge of the mold. Since it is cured at room temperature, the sealing tape can be selected as low-temperature sealing tape. Another advantage of gluing the sealing tape in advance is to avoid the fiber bundle being pressed under the sealing tape during the subsequent layering process. If the fiber bundle is pressed under, it will cause the airtightness inside the vacuum bag and fail to form a vacuum state.
