Medical LSR Overmolded Plastic Connector for Device Assemblies

For projects involving this LSR overmolded plastic connector can be used in:, Medical LSR Overmolded Plastic Connector for Device Assemblies provides a purpose-built medical and healthcare silicone component. Key configuration points include material: Medical-grade LSR + PC / PP / PCTG / Custom Plastic; process: Plastic Injection Molding + LSR Overmolding; silicone hardness: Customizable, commonly 30–70 Shore A, so purchasing decisions can be tied directly to the target application and mating structure.

For OEM and custom programs, the practical questions are how the part fits, what it must resist, and which dimensions or interfaces are critical. The following sections separate performance requirements, material/process information and application details so the product can be assessed more efficiently.

Functional Design Priorities

• The connector can be produced using medical-grade LSR combined with transparent plastic materials such as PC, PP, PCTG, or other engineering plastics depending on the application requirements.
• LSR silicone is directly molded onto the plastic insert, creating a stable integrated structure. This helps reduce assembly steps, improve sealing reliability, and enhance product consistency.
• The soft silicone section provides a flexible sealing interface, helping prevent air leakage, liquid leakage, vibration, and loosening during use.
• The transparent plastic part allows visual inspection and supports applications where clarity, positioning, or flow observation may be required.
• Developed for small precision medical components, this product is suitable for medical instruments that require cleanliness, dimensional accuracy, and stable functional performance.
