Built to make Australian manufacturing more competitive
Good Plastics combines local engineering control with international manufacturing capability.
We help Australian businesses access specialist tooling, production and technical expertise without losing oversight of the project.
Our story
Good Plastics was built on a straightforward belief: that plastics manufacturing can be done more responsibly, and that responsibility can make a business stronger rather than less competitive.
Kulbir Dhanda founded Good Plastics after more than twenty years in plastics engineering, working hands-on across product development, tooling and injection moulding. He set out to build a company that could help Australian manufacturers compete internationally while taking greater responsibility for materials, production and what happens to a product after use.
At the time, many businesses were reluctant to consider bio-based materials or change established manufacturing processes. Kulbir kept going. He built relationships with manufacturers, material specialists and researchers, then focused on turning promising ideas into products that could work in commercial production.
Today, Good Plastics supports product design, precision tooling, injection moulding, 3D printing, international manufacturing, material development and research.



Why Good Plastics exists
Australian businesses often face an awkward choice.
They can manufacture overseas and gain access to scale, specialist equipment and competitive pricing, but lose visibility and control.
Or they can stay closer to home and work within a smaller range of capability.
Good Plastics connects the two.
Our clients work with an Australian engineering and project team while production is delivered through an international manufacturing network.
There is one point of accountability from the first drawing through to the finished part.
Vision and mission
The Next Life Economy
A product’s story shouldn’t end when the customer stops using it.
The Next Life Economy is Good Plastics’ developing framework for considering recovery, processing and the next use of a material from the beginning of product development.
This work is still being developed through research, trials and project-specific partnerships.
We don’t present a future pathway as if it already exists.
Research connected to production
Research matters when it can be applied to real parts, real tools and real manufacturing conditions.
Good Plastics has worked with university research partners on PHA formulation, mouldability, performance and degradation testing.
The work has included commercial trials and is expected to contribute to research papers.

How we work






We look closely at the engineering
Small design and tooling decisions can have a major effect on part quality, cycle time and production cost.

We’re clear about the evidence
Published results, active testing and future goals are treated differently.

We stay accountable
Clients work with one locally managed team responsible for coordinating the project.

We protect confidential information
Client designs, tooling and commercial information are protected throughout the supply chain.

We focus on what can be delivered
A promising idea only becomes useful when it can be manufactured, supplied and used successfully.

Our promise
We’ll communicate expectations clearly and follow through on what we agree to do.
We’ll give you clear advice based on the product, the manufacturing requirements and the available evidence.
We’ll communicate expectations clearly and follow through on what we agree to do.
We’ll keep building stronger connections between local engineering and specialist international manufacturing capability.
We’ll continue investigating how materials can perform during use and move into a more responsible pathway afterwards.
Work with a team that understands the full process
You don’t need to know which service you need before contacting us.
We’ll help you work out the next step.
