Abstract
An apparatus and method for making molded products for marine, automotive, recreational, and other applications. The apparatus and method for making the molded products generally includes a closed mold and an inline mixer for adding a catalyst to a filled resin. The method may include adding a cotton material to a resin to create the filled resin, adding a catalyst to the filled resin, and mixing the catalyst and the filled resin to create a catalyzed, filled resin. The method may also include adding the catalyzed, filled resin to a mold and allowing the catalyzed, filled resin to harden in the mold.
Claims23
A method of making a molded part, comprising:
- withdrawing a filled resin from a container, the filled resin comprising a mixture of resin and cotton flock;
- adding a catalyst to the filled resin;
- mixing the catalyst and the filled resin to create an uncured catalyzed, filled resin;
- adding the uncured catalyzed, filled resin to a mold, the mold being free of reinforcing fiberglass prior to adding the uncured catalyzed, filled resin to the mold;
- and
- allowing the uncured catalyzed, filled resin to harden in the mold.
A method of applying resin, comprising:
- withdrawing a filled resin from a container, the filled resin comprising a mixture of resin and cotton flock;
- adding a catalyst to the filled resin;
- mixing the catalyst and the filled resin to create an uncured catalyzed, filled resin;
- applying the uncured catalyzed, filled resin to a surface the surface being free of reinforcing fiberglass prior to applying the uncured catalyzed, filled resin to the surface;
- and
- allowing the uncured catalyzed, filled resin to harden.
A method of making a molded part, comprising:
- pumping a filled resin from a container into a hose to create a flow of filled resin, the filled resin comprising a polyester resin, cotton flock and calcium sulfate, wherein the filled resin comprises a weight percentage of about 60% polyester resin, a weight percentage of about 30% calcium sulfate, and a weight percentage of about 10% of a cotton flock;
- wherein the cotton flock comprises fibers having an average length of about 380 microns;
- adding MEKP to the flow of the filled resin;
- mixing the MEKP and the filled resin using an inline, static mixer to create a catalyzed, filled resin;
- adding the catalyzed, filled resin to an empty cavity of a mold;
- and
- allowing the catalyzed, filled resin to harden in the mold.
