The selection of two-color injection mold materials is the premise of ensuring the quality of mold processing. Therefore, special attention should be paid to the physical and chemical properties and processing options of materials, so that we can design reasonable molds.
Combined with traditional mold design, CAE technology and computer-aided engineering have great advantages in improving productivity, ensuring product quality, reducing costs, and reducing labor intensity. How to choose the material of the two-color mold, Guangdong, Dongguan City Xin Plastic Mould Products Co., Ltd. has sorted out the following two points for you:
Good thermal stability:
The shape of the parts of the plastic two-color mold is often complicated, and it is difficult to process after quenching. Therefore, it should be selected as far as possible with good thermal stability. When the mold is formed and processed after heat treatment, the linear expansion coefficient is small, the heat treatment deformation is small, and the dimensional change caused by temperature difference rate is small.
Sufficient surface hardness and wear resistance:
The hardness of the plastic mold is usually below 50-60HRC, and the heat-treated mold should have sufficient surface hardness to ensure that the mold has sufficient rigidity.
Due to the large compressive stress and frictional force due to the filling and flow of the plastic, the mold is required to maintain the stability of the shape accuracy and dimensional accuracy to ensure that the mold has a sufficient service life.
