We are an established plastic manufacturer based in Malaysia since 2004. Our company focuses on injection Moulding, Assembly and Spraying & Printing but our product line is constantly expanding to exceed our clients requirement and expectation. KOS plastic is currently expanding into the overseas market and we would like our clients to be a part of our success story.

Established in 1978, W&S Plastics has continued to grow and improve throughout the years.
We are now the largest and most advanced custom injection molder in NSW Australia.
We also have a facility in Johor, Malaysia which commenced production in October 2016. This facility grew from a brand new, empty factory, to an operational state-of-the-art injection molding facility in just 6 months thanks the dedication and hard work of our team.
