Why Choose Plastic Injection Moulding

Unveiling the Marvels of Plastic Injection Moulding

So why choose plastic injection moulding for your products?

In the realm of manufacturing and production, plastic injection moulding stands out as an innovative and versatile process that has revolutionised the way countless industries create their products. At Action Plastics, we are a leading force in New Zealand’s plastic injection moulding industry. In this blog, we will explore the many benefits of plastic injection moulding and we’ll shed light on why it has become the preferred choice for businesses worldwide.

Precision and Complexity

Plastic injection moulding allows for unmatched precision and intricate designs that other manufacturing methods often struggle to achieve. The process involves injecting molten plastic material into a precisely crafted mould, resulting in products with exceptional dimensional accuracy and consistency. This level of precision enables the creation of complex shapes, fine details, and intricate features that can elevate the aesthetics and functionality of the final product.


Cost-effectiveness is a driving force behind the popularity of plastic injection moulding. The ability to produce large quantities of parts with minimal material waste makes it an economical choice for mass production. Additionally, the automated nature of the process reduces labour costs, leading to overall savings in the manufacturing process.

Fast Production Cycles

In today’s fast-paced world, time-to-market is a crucial factor for any business. Plastic injection moulding shines in this aspect as it enables rapid production cycles. Once the mould is created, the actual production process becomes swift, allowing businesses to respond quickly to market demands and keep up with ever-changing customer preferences.

Versatility of Materials

Plastic injection moulding can accommodate a vast array of materials, each offering unique properties suitable for different applications. From conventional polymers to advanced engineering plastics, the versatility of materials opens up a world of possibilities for manufacturers. Whether it’s producing durable consumer goods or specialised components for complex industries like automotive and aerospace, plastic injection moulding can handle the challenge.

Enhanced Product Strength and Durability

Products manufactured using plastic injection moulding exhibit exceptional strength and durability. By adjusting the moulding parameters, manufacturers can control the material’s density, strength, and flexibility, resulting in products that can withstand harsh environmental conditions and heavy usage without compromising performance.

Consistency and Quality Control

Quality control is of paramount importance in any manufacturing process, and plastic injection moulding excels in this area. The automated and repeatable nature of the process ensures consistent product quality throughout the production run. Furthermore, modern moulding technologies incorporate sensors and monitoring systems that detect defects early on, reducing waste and enhancing overall quality.

Sustainable Manufacturing

In recent times, sustainability has emerged as a critical concern for businesses and consumers alike. Plastic injection moulding aligns with sustainable practices in several ways. Firstly, the process’s efficiency reduces material waste and energy consumption. Secondly, recyclable and biodegradable plastics can be used, promoting a more environmentally friendly approach to production.

Why we think it’s the way to go

Plastic injection moulding, with its precision, cost-effectiveness, speed, and versatility, has undoubtedly changed the face of manufacturing. The benefits it offers, from producing complex designs, to sustainable manufacturing, make it the go-to choice for businesses seeking excellence in their products.

As technology advances and environmental awareness grows, plastic injection moulding will continue to shape a world of possibilities for innovative and sustainable production.
