Introduction to Classification and Characteristics of Silicone Mold Forming
Different products are made using different silicone molds, and different silicone molds have different molding methods. How many categories of silicone mold molding methods are there? Below, Xinjia will give you a detailed introduction to the classification and characteristics of silicone mold forming.
1. Compression molding mold
Also known as ordinary press mold. It directly puts the mixed, processed and weighed semi-finished rubber material into a mold, and then sends it into a flat vulcanization machine for pressure and heating.
The rubber material is vulcanized and formed under pressure and heating.
Features: The mold has a simple structure, strong versatility, wide usage range, and convenient operation, making it a significant proportion in rubber molded products.
2. Die casting mold
Also known as transfer mold or extrusion mold. It is the process of placing mixed, simple shaped, and limited quantity rubber materials or rubber block semi-finished products into the die casting mold cavity, squeezing the rubber material through the pressure of the die casting plug, and allowing the rubber material to enter the mold cavity through the pouring system for vulcanization and shaping.
Features: More complex than ordinary molds, suitable for making thin-walled, slender, and easily bent products that cannot be pressed or barely pressed by ordinary molds, as well as rubber products with complex shapes and difficult to add materials.
The products produced using this mold have good density and superior quality.
3. Injection molding molds
It is the process of injecting pre heated plastic material into the injection mold through the pouring system to solidify and vulcanize the mold.
Features: Complex structure, suitable for large, thick walled, thin-walled, and complex shaped products. High production efficiency, stable quality, and the ability to achieve automated production.
4. Extrusion molding mold
Various cross-sectional shapes of rubber profiles are made into semi-finished products through the molding mold of the machine head, achieving the purpose of preliminary shaping. Then, after cooling and shaping, they are transported to the vulcanization tank for vulcanization or used as pre formed semi-finished rubber materials required by the compression molding method.
Features: High production efficiency, stable quality, and the ability to achieve automated production.
