A Chinese injection molding company is planning to build a brand new rubber/silicone windshield wiper blade production line. I am involved in this project. I am totally new in this area. I wonder if anyone could tell me where I could get the formulation/technology internationally and what kind of equipment/process should be used? Or any engineering firm could help? The company is willing to pay for the information/technology.

Materials
On the equipment side you will need:
1. Intermix-type mixer.
2. 2x mills sized to fit with the mixer.
3. Straining extruder to remove grit etc from the compounds
4. Rubber extruder.
5. Microwave and hot air curing tunnels.
6. Length cutter.
I'm in no position to help regarding the formulations used as I work for the Malaysian Rubber Board and they won't let me help other asian-based companies.

Mixer with intermeshing rotors - Kobe and Farrel are two manufacturers of these.
Extruder with barrier (Mailiffer, HIM) screw - Farrel, Kobe, Iddon.
No one moulds wiperblades these days - too inefficient.

Many blades are still molded, mostly in China, but even some here in the USA.
Chinese mixers do not have access to the high quality/low grit raw materials that we do, and this makes extrusion of this type of product impossible.
This is a lousy market to be in...tell your investors to look at something more profitable.

If you use high quality ingredients and pass the mixed compound through a straining extruder where's the problem with extrusion?
