Advantages of Overmolded Products

Silicone-metal overmolded products (commonly used in electronic device casings, medical equipment components, industrial seals, home hardware, etc.) are composite products where silicone and metal (such as aluminum alloy, stainless steel, brass, etc.) are tightly bonded through processes like injection molding, overmolding, and insert molding. This combination breaks through the performance limitations of single materials—it not only retains the supporting advantages of metal, such as 'structural sturdiness and dimensional stability,' but also incorporates the functional characteristics of silicone, such as 'softness, anti-slip property, sealing performance, and weather resistance. Additionally, the 'one-piece molding' process eliminates splicing gaps.

Excellent Structural Performance

The 'flexible cushioning' of silicone complements the 'rigid support' of metal. Combined with the 'seamless feature' of the overmolding process, the product is both impact-resistant and capable of adapting to structural stability requirements in complex environments.

Adequate Metal Support for Deformation & Impact Resistance: Metal provides core structural support for the product, featuring high hardness and high strength. It can withstand external extrusion and impact without easy deformation or fracture.

Silicone Protection to Prevent Metal Scratches & Impact Damage: Silicone covers the metal surface (or key contact areas). With its high elasticity (rebound rate ≥ 80%) and low hardness (Shore A 30-70), it can absorb external impact and friction.

Seamless Overmolding for Strong Structural Sealing: The overmolding process enables tight bonding between the silicone and metal interfaces, with no easy peeling. It forms a 'seamless sealing structure' with high sealing performance, and for specific products, it also offers extremely high water resistance.
