適用於醫療器材的醫用級 LSR 包覆成型塑膠連接器

Medical Grade LSR Overmolded Plastic Connector is a precision-molded medical component made by combining rigid medical-grade plastic with soft liquid silicone rubber through an overmolding process. The transparent plastic section provides structural support, positioning, and connection function, while the LSR silicone section offers reliable sealing, flexibility, anti-leakage performance, and comfortable assembly.

This type of connector is widely used in medical devices, respiratory equipment, nebulizers, diagnostic instruments, fluid transfer systems, and other medical assemblies that require clean, stable, and precise sealing performance.

The product can be customized according to the customer’s drawing, sample, material requirement, hardness, dimension, color, and application environment.

主要特色

Medical-Grade Material Selection

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.

Integrated Overmolding Structure

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.

卓越的密封性能

The soft silicone section provides a flexible sealing interface, helping prevent air leakage, liquid leakage, vibration, and loosening during use.

Transparent Plastic Body

The transparent plastic part allows visual inspection and supports applications where clarity, positioning, or flow observation may be required.

Suitable for Medical Device Assembly

Designed for small precision medical components, this product is suitable for medical instruments that require cleanliness, dimensional accuracy, and stable functional performance.

製造流程

The product is manufactured through a two-step molding process.

First, the rigid transparent plastic insert is produced by precision injection molding. Then, the plastic insert is placed into an LSR mold, where liquid silicone rubber is injected and vulcanized around the plastic part. This creates a strong and accurate plastic-silicone integrated component.

Compared with traditional manual assembly, LSR overmolding improves product consistency, sealing stability, and production efficiency. It is especially suitable for medical components with complex shapes, tight tolerances, and strict sealing requirements.

Why Choose LSR Overmolding for Medical Connectors?

LSR overmolding is an effective solution for medical connectors that require both rigid support and soft sealing performance. The rigid plastic part ensures strength and accurate assembly, while the silicone part improves sealing, flexibility, and user safety.

This structure can reduce the need for separate sealing rings, adhesives, or manual assembly. It also helps improve product reliability, cleanliness, and production repeatability.
