Key points of liquid silicone mold casting design

Design of runner pouring system.

Cold runner molding is one of the important processing characteristics of liquid silicone

The cooling system needs to be designed inside the cold nozzle:

There is a big difference between cold runner molding and hot runner systems. The inside of the cold runner needs to be designed to carry water. If the runner between the cavity and the cold runner is too hot, the material will begin to solidify before injection, and the product is prone to cracking. Glue and other phenomena.

The cold mouthpiece needs to be designed with a closed system and automated production, with shorter cycles:

The design of the cold nozzle requires a needle-valve closed system, and the glue port is designed to be between 0.5-0.8mm. The valve needle system needs to be designed with a height-adjustable structure to facilitate fine-tuning the flow through the needle valve.

Cold mouth nozzle needs to design the amount of glue control system:

Miniature products such as injection-molded silicone seals, whose weight is less than 1 g, need to design a precise control system for the amount of glue to ensure that the amount of glue in the flow channel can be controlled and adjusted.

Miniature products, designed with a precise control system for the amount of glue to ensure that the amount of glue in the flow channel can be controlled and adjusted.
