According to an aspect, the molding system includes molding-system elements configured to process a molding material. The molding system includes a mold surface configured to cooperate with the molding-system elements. The molding system also includes a fibrous-insert generating mechanism configured to generate a fibrous insert onto the mold surface. The mold surface, in use, encapsulates the fibrous insert received by the mold surface with the molding material, at least in part.
TECHNICAL FIELD The present invention generally relates to molding systems, and more specifically the present invention relates to, but is not limited to, encapsulating a fibrous insert with a molding material.
BACKGROUND There is a growing demand for glass reinforced thermoplastics parts, particularly in the automotive industry. Glass fibers are used to reinforce the basic thermoplastic structure to improve the strength and impact resistance of the finished part. There are various methods of combining the glass fibers with the plastic. Molders of reinforced thermoplastics using direct long-fiber compounding are seeking a technology that allows the molder to produce a glass-mat thermoplastic (GMT) composite sheet. This development is driven by a desire to reduce raw-material costs by not having to buy a preconfigured sheet. Do-it-yourself compounding also gives GMT molders a means of reusing their scrap. Further savings can be gained by an immediate transfer of a freshly-made GMT sheet into a press while still pliable, which eliminates a need to reheat the sheet in a reheat oven.
SUMMARY In a first aspect of the present invention there is provided a molding system, including molding-system elements configured to process a molding material, a mold surface configured to cooperate with the molding-system elements, and a fibrous-insert generating mechanism configured to generate a fibrous insert onto the mold surface, the mold surface, in use, encapsulates the fibrous insert received by the mold surface with the molding material, at least in part.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS FIG. 1 is a side view of a molding machine 10 according to the first embodiment of the present invention. The molding system 10 includes a fibrous-insert generating mechanism 12. The fibrous-insert generating mechanism 12 is part of an end-of-arm-tool 13. The fibrous-insert generating mechanism 12, when activated, generates a fibrous insert 14 on a fiber-receiving fixture 16 of a mold surface 18. The mold surface 18 is defined by a mold. The mold includes a primary mold half 20 and a secondary mold 22 that defines a mold cavity in cooperation with the primary mold half. The secondary mold half 22 defines the mold surface 18. In an alternative, the primary mold half 20 defines the mold surface 18. The mold cooperates with molding-system elements to encapsulates a molding material on the generated fibrous insert 14 in cooperation with the mold surface 18.
Referring to FIG. 2, the molding system 100 includes a fibrous-insert generating mechanism 102. The fibrous-insert generating mechanism 102 is part of an end-of-arm-tool 103 (hereafter called the �EOAT� 103). The fibrous-insert generating mechanism 102, when activated, generates a fibrous insert 104 on a fiber-receiving fixture 106 of a mold surface 108. The mold surface 108 is defined by a mold. The mold includes a primary mold half 110 and a secondary mold 112. The secondary mold half 112 defines the mold surface 108. In an alternative of the embodiment, the primary mold half 110 defines the mold surface 108. The mold cooperates with molding-system elements to encapsulate the generated fibrous insert 104 with a molding material in cooperation with the mold surface 108. The advantage of the fixture 106 is that the fiber is generated and used on a portion of a mold surface that requires fibrous reinforcement, and in this way, waste of fibrous material is reduced by avoiding the cutting away of material from the fibrous insert.
