    • A detailed embodiment of the invention described herein includes a method and apparatus for pultrusion of a plastic member having a non-wood (e.g., bamboo) reinforced core (325). The apparatus includes an input and series of die assemblies for taking bamboo tape and embedding it in an appropriately shaped composite member. The die assembly may include a finger die (315), an encapsulation die (410), a forming die (420), and a chilling die (430). A pultrusion unit maintains production at an efficient and desired rate by use of pressure sensitive clamps to pull the product forward through the die units. A colorizer unit and embossing unit allow particular appearances to be produced in the end product. Alternative embodiments are also shown including the processing of bamboo into tape and ribbon forms usable by a pultrusion machine.

    • A method for compression molding a thermoset article includes providing first and second movable mold dies providing a mold cavity. A thermosettable workpiece is placed on the first mold die. The workpiece is heated to a gel. At least one of the mold dies is moved toward the other to compress the workpiece between first and second die surfaces. A first mold clamp pressure is applied to the workpiece at a predetermined pressurization to shape the workpiece. The workpiece is cured into a thermoset article. An electrical property of the workpiece is measured as a function of time. A gelation period during which the electrical property changes in value until reaching a turning point corresponding to a gelation peak value is detected. A gelation peak time of the workpiece is determined, the gelation peak time coinciding with the gelation peak value.
    • 一种用于热塑性制品的压缩成型的方法包括提供提供模腔的第一和第二可动模具。 将热固性工件放置在第一模具上。 将工件加热至凝胶。 模具中的至少一个朝向另一个移动以在第一和第二模具表面之间压缩工件。 第一模具夹紧压力以预定的加压施加到工件以成形工件。 工件被固化成热固性制品。 测量工件的电气特性作为时间的函数。 检测电气特性在达到与凝胶化峰值对应的转折点之间变化的凝胶化期间。 确定工件的凝胶化峰值时间,凝胶化峰值时间与凝胶化峰值一致。
