    摘要： A moulding tool (20) for powder injection moulding a cemented carbide or cermet component (1), said component (1) having a through hole (2), said moulding tool (20) comprising;
    at least a first and a second tool part (21, 22, 23, 24) arranged to define at least one mould cavity (25) for forming a component (1);
    at least one inlet channel (30) for introducing moulding material (3) into the mould cavity (25), said inlet channel (30) extending through the first tool part (21) to the mould cavity (25), and comprising an outlet end (33) having an outlet opening (34) for discharging moulding material (3) from the inlet channel (30) into the mould cavity (25);
    at least one core (40) for forming a through hole (2) in the component (1), said core (40) having an end (41) and being arranged to extend into the mould cavity (25) along a longitudinal axis (X) in a direction towards the outlet opening (34) of the inlet channel (30), wherein
    the end (41) of the core (40) is adapted to close the outlet opening (34) of the inlet channel (30) and that the core (40) is arranged movable along the longitudinal axis (X) such that the end (41) of the core (40) may engage with the outlet opening (34) of the inlet channel (30).

    摘要： Improved particleboard and methods for fabricating improved particleboard (e.g., natural fiber/material -based particleboard) are disclosed. More particularly, the present disclosure provides systems/methods for fabricating particleboard (e.g., formaldehyde-free particleboard) utilizing natural fibers/materials (e.g., lignocellulosic materials), wherein the particleboard has improved performance characteristics and/or mechanical properties. Methods for fabricating fiber-reinforced biocomposites (e.g., natural fiber-reinforced wheat gluten biocomposites) are disclosed. For example, systems/methods for fabricating particleboard from lignocellulosic materials (e.g., coconut materials), along with a binder material (e.g., wheat gluten), are provided. In general, the fiber or lignocellulosic material is treated with sodium hydroxide and/or a silane coupling agent as an adhesion promoter to enhance interfacial adhesion between the fiber and the binder. For example, (3- triethoxysilylpropyl)-t-butylcarbamate (MISO) (a masked isocyanate functional silane) was utilized to improve interfacial adhesion between the binder and the natural fibers.
