With the rapidly increasing market demand for silicone cartridges, molds and injection molding production lines for silicone cartridges are an excellent investment direction. However, due to the particularity of silicone cartridge products, their molds are different from ordinary molds, so special attention is required when selecting silicone cartridge molds.
Product Structure and Molding Key Point
A silicone cartridge has a long body with thin wall thickness. During injection molding, the mold core is prone to offset deflection, resulting in uneven product wall thickness. To ensure the accuracy of product wall thickness, solutions must be implemented simultaneously from mold design, machining precision and steel material selection.
In mold structural design, a robust reinforced base must be designed for the core to minimize core shaking and deflection. In terms of machining accuracy, strict precision control is required to reduce dimensional deviations in product wall thickness. For steel material selection, quenched stainless steel is adopted. It ensures high rigidity of the core to avoid deformation, and also prevents later rust-related mold maintenance problems that would affect wall thickness consistency.
Due to the strong market demand for this product, molds are mostly designed as 4-cavity,8-cavity or 12-cavity. Therefore, runner balance is extremely important. It is recommended to adopt valve gate to reduce injection pressure and effectively avoid product eccentricity.
With the development of automated production, IML technology has been widely used in more and more factories, including silicone cartridge production. It is necessary to confirm in advance whether IML will be applied, as the mold must be pre-designed and adapted to the center distance of the IML robot manipulator.
