The Key Role of Silicone Molding in Medical Device Manufacturing

In the field of medical devices, silicone molding technology has become a key manufacturing process due to its biocompatibility, high-precision replication capabilities, and rapid response to demand. This technology enables the efficient replication of complex structural components, such as catheters, prosthetics, and surgical instrument parts, ensuring smooth surfaces and precise details that meet medical-grade precision requirements. Its material adaptability supports a variety of medical-grade resins, allowing it to simulate the properties of materials like ABS and PC while maintaining the advantages of low cost and flexible production, making it particularly suitable for small-batch customized needs. Additionally, silicone molding shortens the product development cycle, accelerating the transition from prototype to mass production and helping enterprises rapidly iterate on innovative designs to enhance the safety and reliability of medical devices. This technology provides a flexible and cost-effective solution for medical device manufacturing, driving the industry toward greater efficiency and personalization.

How resin enables mass production of sculptures

Traditional sculpture relies on manual carving, which is inefficient and difficult to replicate details. Resin mold technology achieves large-scale production through precise replication:

1. Original mold reproduction: After the artist completes the sculpture, a mold is made of silicone or fiberglass to perfectly preserve the texture and shape, ensuring that the replica is consistent with the original.

2. Resin infusion: Inject liquid resin into the mold, cure it, and demold it to quickly generate high-precision replicas, supporting various materials such as imitation metal and stone.

3. Batch expansion: One set of molds can be reused dozens of times, significantly reducing production costs and meeting large-scale demands such as art derivatives and urban sculptures.

This technology is widely used in the fields of museum artifact replication, commercial customization, etc., allowing precious artworks to be exhibited in a "clone" form, while helping sculpture factories efficiently deliver orders. Resin molds not only preserve the artistic soul, but also promote creativity from "isolated products" to "mass production", becoming the core tool of modern sculpture production.

Research on CNC machining and surface treatment process of high-strength aluminum alloy molds

High strength aluminum alloy molds are widely used in aerospace and other fields due to their lightweight and high-strength characteristics. However, their high hardness leads to prominent issues of machining deformation and surface wear. This study optimized the five axis CNC machining parameters and adopted dynamic cutting force control technology to effectively reduce tool wear and thermal deformation; The combination of plasma spraying and laser cladding composite surface treatment significantly improves the surface hardness and wear resistance of the mold. Experiments have shown that this process extends the lifespan of the mold by 40% and reduces the surface roughness to below Ra 0.2 μ m, meeting the requirements of harsh working conditions. The research provides innovative solutions for the precision manufacturing of high-strength aluminum alloy molds, which is of great significance for promoting the development of lightweight equipment.
