Common Questions

Frequently Asked Questions

Plastic injection moulding is a manufacturing process where raw plastic material (in the form of pellets) is melted and injected into a custom metal mould under high pressure. Once the plastic cools and solidifies, the mould opens to release the finished part. It is an incredibly efficient process that allows for high precision, strength, and repeatability across thousands of parts.

The upfront cost of a mould varies significantly depending on the size of the part, its complexity, the number of cavities required, and the type of steel used. A simple, single cavity mould for a small part requires an initial investment, while complex, multi cavity moulds for high volume mass production require a larger investment. However, once the mould is created, the cost per part becomes extremely low. We provide fast, transparent quotes tailored to your exact specifications.

We can work with a vast variety of commercial thermoplastics, including Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Nylon, and High-Density Polyethylene (HDPE). If you are unsure which material is best for your product, our experienced team can provide expert advice based on the durability, flexibility, and finish you require.

Absolutely. While injection moulding is famous for mass production, our efficient machinery and direct approach make us highly competitive for smaller, custom production runs. We regularly work with inventors, small businesses, and niche industries to deliver cost effective manufacturing solutions without the massive minimum order quantities often demanded by overseas factories.

You do. Once the tool is paid for and manufactured, you retain full ownership and all intellectual property rights for your product. We also provide free general tool maintenance for all our active moulding customers and we safely store your moulds in our modern facility so they are ready to go whenever you need your next run.
