High quality moulds last longer and produce better quality parts which in turn means less finishing on the parts, avoiding excess labour and the associated part costs. With extensive experience in mould making, we cannot overstate the importance of paying attention to moulds at the earliest stages of part design. Mould quality is critical to the part quality and ensuring smooth, continuous production. Customers are encouraged to involve us in design of their moulds to help ensure the lowest project cost. |
Design for manufacture is essential to ensure a high-quality, cost effective part can be made repeatedly. Carefully considered release angles, positioning of split lines and other such elements are essential, to optimise part quality or streamline manufacturing costs of the part. |

Basic moulds can be made by hand from customer parts or prototypes. Simple moulds can also be made from wood or silicone. For higher precision parts we recommend CNC machined patterns which are then used to make moulds that have more precise dimensions and allow for more complex shapes and features. As an emerging solution, we also have the possibility to make smaller moulds and patterns from 3D printed models, hand finished using conventional techniques. |
The use of precise mould locators ensures that the different parts of split moulds fit exactly every time. This ensures high repeatability for parts, especially when multiple parts make an assembly. Reinforcement of the mould with wood or steel minimises any movement when making the parts, ensuring the consistency, time and time again. Some may consider it ‘over-engineering’ but experience has demonstrated that substantial mould construction and support are key factors in part consistency. |

Mould maintenance is an important part of the manufacturing process; from ensuring the surface is smooth and defect free, to regular cleaning and waxing. This is particularly important as the quality of the part is a direct reflection of the surface of the mould. Moulds are routinely taken out of production to be polished back to a high gloss or repaired to ensure the parts they produce need the minimum of work once made. |
