Mastroplas Plastics is an Australian owned and operated company, specialising in the design, tooling and manufacturing of plastic injection moulded products.

Prime examples were molding non-communicating passageways through a plastic manifold, molding critical tolerance pacemaker components, and even molding around glass formations without breaking or cracking. Our advanced injection molding equipment makes even the most difficult projects possible.

Full Technical Support - Throughout the process, Mastroplas guarantee to offer full technical support and assist in design, development and manufacturing of any new product.

We provide assistance throughout each stage of your program, from design recommendation through mold tooling fabrication, prototyping, first article approval, process validation, full scale production medical molding, and transfer of turnkey system to customer facilities if requested.

Highest Standards - Our machine and ancillary equipment are maintained to the highest standards and are continually updated to ensure we are a step ahead with technology and job capability.

We are a full service plastic injection moulding manufacturer, confidently geared to assist in taking any project from concept inception through to product design, tooling and manufacture.

With over 25 years experience, Mastroplas has the understanding and capability to service a range of industries, including -

Medical injection molding is a manufacturing process that produces plastic medical devices and components. It involves melting plastic resin pellets and injecting the molten material into a mold to create a specific shape. This process allows for precise control over the product's size and shape and is subject to strict quality and regulatory standards.

However, there are other types of plastics called thermosets that also can be used for injection molding, but the process is far different. These materials are most likely not going to be used for medical molding as they cannot be recycled as easily as the thermoplastic materials.  Because of this, you don't see thermosets used as often as you do thermoplastics. A good example of a thermoset is your car tires. This is where they cannot be melted down and reshaped into something.

Injection molding is a very common way to form plastic parts and components. Depending on the material, the parts can be very strict with their tolerances as well as easy to process. Injection molding is one of the most common types of forming plastics. It is used in a variety of industries and not just for medical injection molding. In fact, you probably have a wide variety of injection molded parts all around you and simply don't know it. Your basic pens, your keyboard, and even your phone have injection molded components in them. ​

In the medical field, we often see metal combined with the plastic part. This is called insert molding and is a very common practice for injection molders to do. You see this all over the medical arena from needles to EKG hook up leads and more.

24/7 Production - Our factory is flexible to your project requirements and is able to turn around production in short periods of time with our ability to run jobs 24/7.

We are a full service plastic injection moulding manufacturer, confidently geared to assist in taking any project from concept inception through to product design, tooling and manufacture.

Sometimes the components need to be manufactured separately and then assembled. This is very common in many cases and this can be done by hand or robot.

Our skill set is broad, allowing us to respond to any customer requests with knowledge, understanding and proficiency. We strive to find a solution for our clients’ needs and always deliver on price with the highest quality and service.

Clean Room - We have a fully functional clean room that enables us to manage projects in industries such as medicine, food service and consumables.

Computerised Production - Our production process is assisted by a fully computerised production/planning system that ensures every job is completed as per the required specifications, on time and to the highest quality standards.

The most common types of materials used in medical insert molding are thermoplastics. These are materials that can be heated up into a molten state and pushed through a barrel into a mold. These molds can simply be open and shut type designs, which are what you would expect for, say a simple product such as a cake mold. Or they can be very complex with moving side parts called slides. Of course, the simpler the mold the better for maintenance and longevity. However, complex parts will need these complex designs in order to produce the desired part.

The process is capable of making FDA approved medical devices that are both durable and reliable. This type of molding can also be used to make prototypes to send and get the much-needed FDA approval. Medical injection molding can be performed in a clean room and the components can be sterilized without harm as well. Let's take a look at injection molding.​

Medical injection molding is a core technology of Aberdeen Technologies and represents a cutting edge solution to the manufacturing needs of healthcare companies who produce medical molded devices. As an insert molding manufacturer, we provide assistance to device manufacturers who approach us with new product concepts and ask us to mold parts for clinical trials and marketing evaluations.

Wide Range of Resins - Part of our custom plastic injection moulding service offering enables us to process a wide range of plastic resins including engineering material such as polycarbonates, nylons, acrylic and polyurethanes.

Aberdeen’s primary goal is total customer satisfaction for even your most challenging projects. Our company culture is one of honor, respect and service with the highest degree of competence and professionalism that you will find anywhere.

Injection Moulding Machines - Our factory is equipped with a range of plastic injection moulding machines that can cater to the production of components weighing anywhere from 5 grams to 500 grams.

Once these new devices are produced, we assist our customers in transitioning the project into the production phase. Quality and customer satisfaction are our primary goals, and Aberdeen can work with both high and low quantity requirements with over 700 square feet of cleanroom injection molding space.

Mastroplas has a wide range of plastic injection moulding machines that allow us to confidently respond to any project, big or small, that requires a professional, quality solution. Our experience ranges across both domestic and commercial projects and products such as -
