Undermount Sink Mould

SMC product hole forming process characteristics：

In fiber reinforced resin matrix composite products, for the hole requirements are not high, usually in the molding, the hole molding and injection mold similar to the structure, according to the structural characteristics of the hole, the use of touch, insert, touch and insert and other forms.

SMC premix is a sheet material, and its internal fibers are distributed parallel to the plane, presenting anisotropy. Premix laying process has an important effect on the quality of SMC products. During the molding process, with the application of pressure, the resin carries the fiber flow in the cavity, and finally fills the whole cavity space and reacts to cure; At the same time, it is necessary to remove the gas or volatile components. The study of Song Xiugong et al. showed that increasing the tower structure with local layings and selecting the appropriate process was beneficial to exhaust and reduce the pinhole, but it would largely cause the loss of mechanical properties of SMC products. Especially in the presence of SMC products require high quality of hole, the moulding process of premix resin can flow freely, but fiber due to the mold core block, appear uneven distribution and orientation, cause pore wall around less fiber, mechanical performance is poor, the part of the fiber content is low in crack appeared in the process of stripping even broken.

For SMC products with high quality requirements of the installation hole, if the fixed core structure of the injection mold molding hole is used, the fiber is punctured by the fixed core in the flow molding process, but also easy to cause molding products after the installation hole flying edge is too thick, and the inner edge of the burr, bring inconvenience to the subsequent installation.
