We’re delighted to share that Bowles and Walker has been named a…
Toolmaking for Over 50 Years
In-House Mould Design
Fully Equipped Toolroom
We design, build, repair and modify mould tools to produce an exceptional end product.
At Bowles and Walker, we design and manufacture injection mould tools for a wide range of products and industries. From a brand new tool for a product launch or support with an existing mould, we’ll work with you to find the most cost effective solution.
We support businesses of all sizes. Some of our clients run full production lines and want to improve production quality or develop their product. Others come to us with a first idea or prototype to work on from scratch. Whatever stage you’re at, we’ll guide you through the options and make sure your plastic mould tooling is built to last.
Every project starts with a conversation. Tell us what you’re working on and we’ll help you plan the right mould tooling solution.
Plastic injection tooling is an incredible investment in the long term. A well-built, custom tool ensures each product is precise, accurate and durable – and it’s yours to keep and use with any manufacturer. Once the tool is made, production becomes quick and cost effective, with minimal waste.
The benefits:
Every tool is unique. We take time to understand your product and its requirements before suggesting the more suitable approach. This ensures the design supports smooth production, consistent quality and cost efficiency.
Using our own CAD software, we create a 3D detailed model of your plastic mould tooling. We consider every aspect of the design to streamline the end product – from the product’s geometry, the characteristics material being used, and the moulding machine specifications.
We craft your injection moulding tool ready for production. Tools can be made from aluminum steel, and stainless steel depending on your requirements. We can also provide long-term maintenance and modification for your existing tools.
We answer your common questions surrounding mould tooling.
What is a mould tool?
An injection mould tool, also known as a mould, is an integral part of the injection moulding process. The purpose of the tool is to turn molten plastic into a specific shape through the core and the cavity. These two parts come together to form the desired shape of the plastic product. Once the mould tool is designed, it is used in alongside a moulding machine to produce plastic parts in large quantities.
What material is used for toolmaking?
Any material used to make a mould need withstand the high temperatures and pressures that come with the injection moulding process. P20, H13 steels and alumni, are the most common materials to make a mould tool.
What is the difference between tooling and mould?
Tooling refers to all tools in manufacturing. A mould is the shaping process in injection moulding. Making moulds is just one aspect of the broader tooling process in plastic manufacturing.
How are injection tools made?
on the plastic part design requirements. A suitable material is chosen and shaped using CNC technology. Heat treatment may be added for durability. The assembled mould, with a cavity and core, is then polished for a smooth finish.
Can you look after my tool?
We will maintain new and existing moulds to help preserve their life and quality. We can also carry out any repairs or modifications where necessary.
Who owns the tool?
The customer has full ownership of their tool. All of the tools we make are bespoke to the customer and are kept in our factory in Norfolk. This means that no other company can use your tool to produce your products.
