Step 1:

Thermoplastic injection

Step 2:

Silicone overmolding

Area 1: Thermoplastic injection:

Water cooling: 90°C / 194°F* *For PA6 or PA66 GF30

Area 2: LSR injection (cold sprue bush):

Water cooling: 20°C / 68°F

Area 3: Silicone vulcanization:

Core heating: 180°C / 356°F

2 options: injection with a 2K-machine or an 1K-press

with an additional injection unit

Silicone vulcanization on nylon (PA6 or PA66) but also

possible on PPS or PPA resin

Strengths:

Simultaneous cycle time

Productivity and cost savings

(Fully automated production)

Non-post molding operation

(like curing, assembly…)

Scrap rate optimization

LSR from Wacker qualified following PSA

and VW specifications

No chemical bonding, possible

substitution for After-Sales
