Sanko Gas  
Overview Gas assisted molding technology has been around for quite some time. This concept started in the 70s and development begin in the early 80s by a UK company.
What is required?

You need the following equipments
1) A controller like Sanko controller
2) A High pressure compressor or booster
3) Nitrogen source which can be from cylinder or nitrogen generator

Who need it?

1) Plastic Molding Vendor
2) Manufacturer
3) Product Design / Development, etc

What products need this technology? 1) Big and bulky products
2) Thin wall precision parts

Why?

1) Reduce weight and in return save cost
2) Reduce cycle time to achieve higher productivity
3) Improve flow (high pressure)
4) Reduce wrapage. Eg. Thin wall& irregular wall thickness
5) Improve cosmetic look
6) Stabilize shrinkage and reduce In-mold stress on parts
