The Best Performing Grades For Plastic Injection Moulding
Plastic injection moulding is one of the most efficient and widely used methods for producing plastic parts at scale. It’s ideal for high-volume, complex or precision components because it offers exceptional repeatability, tight tolerances, and high surface finish. Plastic injection moulding is a widely used process across industries like automotive, electronics, homeware, and medical devices.
At Naphtha Plastics, we specialise in supplying high-quality polymers to injection moulders who depend on both the material and the consistency of supply to maintain their production lines. We provide a broad selection of both prime and recycled thermoplastics, which helps our customers meet performance standards while also addressing sustainability goals.

The Challenge: Consistency, Speed, and Quality
Plastic injection moulding is a high-speed process where cycle times can range from 20 to 60 seconds per part. Any delay in material delivery or inconsistency in polymer quality can lead to production stoppages, costly waste, or failed quality checks. This is especially true in advanced moulding applications such as gas-assisted, multishot, or in-mould decoration processes, where material behaviour under pressure and temperature must be precisely controlled.
Our Solution: Reliable, Versatile
Polymer Supply
We solve these problems by offering:
Fast and reliable delivery of raw materials to ensure your operations run without disruption.
Material selection advice to help customers choose the right polymer grade for performance, ease of moulding, and end-use requirements.
Stock availability in both virgin and recycled grades, supporting cost efficiency and environmental targets.
Technical support, including assistance with mouldflow analysis and design-for-manufacture considerations to prevent defects such as sink marks, warpage, weld lines or poor flow.
Material Options and Benefits
Our range covers the most commonly used engineering and commodity thermoplastics, including polypropylene (PP), polyethylene (PE), nylon (PA), ABS, polystyrene (PS), and more, available with various fillers, colourants, or impact modifiers.
Benefits to our customers include:
Increased production uptime with on-time material supply.
Improved part quality and surface finish with consistent material performance.
Support for sustainable production goals through recycled content options.
Reduced defect rates thanks to the correct matching of material properties to tooling and design.
For manufacturers producing products of all sizes, from small intricate parts to large structural pieces, Naphtha Plastics is committed to being a dependable partner to your injection moulding business.
