Custom Molded Silicone & Rubber Parts - Injection & Compression Molding
Rapid silicone rubber prototyping. High- or low-volume compression & injection molding part production.
Silicone rubber compression molding
Silicone rubber compression molding uses uncured rubber that has been preformed into a controlled shape, such as a disc. The mold surrounds the part and compresses it between two plates under high pressure. The high temperature and pressure vulcanize the rubber to cure the part. Pins automatically eject the part from the mold, speeding up production. Silicone rubber compression molding offers excellent chemical resistance, durability and flexibility, and also allows the use of multiple colors, textures and durometers in a single product, providing designers and engineers with greater product design flexibility.
Silicone rubber Injection molding
Silicone rubber injection molding is to inject liquid silicone rubber into the mold cavity under high pressure and high temperature. The silicone rubber then cures and cures to form the finished product. Liquid silicone rubber can flow into tight spaces and accurately reproduce fine features. In addition, silicone rubber has excellent heat resistance, electrical insulation, and biocompatibility.
Silicone rubber compression molding process & characteristics
Silicone rubber compression molding is a manufacturing process used to create silicone rubber products, such as seals, gaskets, and o-rings. This method is known for producing high-quality, high-precision parts with consistent dimensions and excellent surface finish. It also allows for customization of the rubber’s properties, such as hardness and color.
Compression Molding
The equipment and tools required for the compression molding are much simpler, which means less capital investment. The form of molding is suitable for mass and rapid production of products with simple design, product tolerance of ±0.05mm, and low budget.
Silicone compression molding is a manufacturing process used to produce high-quality silicone rubber products. Here are the basic steps involved in the process:
How it Word
Preparing the silicone material: The silicone is typically in the form of a compound or a mixture of silicone polymer, fillers, and other additives. The compound is typically mixed in a high-speed mixer or a two-roll mill until it is uniform.
Preparing the mold: The next step is to prepare the mold. The mold is typically made of steel or aluminum and is designed to the shape of the final product. The mold is usually made in two halves, which are held together using a clamp.
Loading the mold: Once the mold is prepared, the silicone material is loaded into the mold. The mold is filled with the silicone compound using a hydraulic press or an injection molding machine. The amount of material loaded into the mold is critical to ensure the final product meets the desired specifications.
Compression and curing: Once the mold is filled, the two halves of the mold are clamped together, and the silicone material is compressed to the desired shape. The mold is then heated to a specific temperature, typically between 150°C to 200°C, to cure the silicone material. The curing time varies depending on the thickness of the final product and the type of silicone used.
Demolding: Once the silicone material is cured, the mold is opened, and the final product is removed. The excess material is trimmed, and the final product is inspected to ensure it meets the desired specifications.
