Implant-Grade Silicone Molding: Vertical LSR Injection + Precision Vacuum Mixing

Materials answer “what to use”; equipment answers “how to mold it”. For precision micro silicone parts, BIO offers a material + equipment + process-direction reference with its equipment manufacturing partner.

Target applications

Cochlear implant components
Medical-grade silicone overmolding for connectors
Electrode insulation encapsulation
Invasive BCI electrode encapsulation

Machine highlights

Magazine-type feeding — eliminates residual silicone in feed lines
No material transfer between cup and barrel — avoids trapped air and dosing drift
Pairs with the precision mixer for near-zero material loss
Mobile footprint that saves cleanroom space
Clamping force, pressure, speed and temperature tunable to production requirements
An equipment-based path to defects caused by manual glue dispensing

How it pairs with materials

This equipment direction is complementary to BIO’s medical-silicone selection: molding-grade LSR, overmolding and insulation applications can be matched to medical-grade silicone grade directions by contact mode and process. See the cochlear implant solution and BCI solution. Final fit follows sample evaluation and the customer’s own process validation.

Manufacturer & roles

The equipment is manufactured by Guangzhou Tianyuan (TYM) Silicone Machinery. BIO provides material selection and equipment-pairing consultation for medical-silicone customers; commercial terms, delivery, installation and after-sales service follow the manufacturer and written confirmation.
