Overview:
A medical device manufacturer needed to produce components combining thermoplastics (ABS) with liquid silicone rubber for applications such as valves and sealing membranes.

Challenges:

• Poor bonding between LSR and thermoplastics

• Strict medical-grade requirements

• Sterilization resistance needed

• High dimensional accuracy

Solution:
We developed a customized LSR overmolding system with:

• Dynamic mold temperature control

• Surface pre-treatment integration

• High-precision dosing system

• Cleanroom-compatible configuration

Results:

• Strong bonding between ABS and LSR achieved

• Stable performance after sterilization

• High repeatability for medical production

• Reduced rejection rate

Application Industry:
Medical / Healthcare / Laboratory devices
