In manufacturing there is no ‘one size fits all’ because every part or tool is different but there are preferred methods of achieving the quality and accuracy needed when building these items. Injection moulding is one of the top methods to create prototypes because it is accurate, delivers high quality and is very cost affordable but there is more than one way to accomplish this.
The reaction method is especially designed for larger pieces that will be produced in low to mid quantities. This is one of the keys to using the right company because your goal is to make money and so is theirs but you want them to look out for your best interest and not just the bottom dollar.
The right company is going to utilize the most effective method to build the part so it has the durability, functionality and quality that you are looking for even if this means that they use a method that is not quite as expensive. This is a customer service friendly attitude that helps to earn new business and keep customers returning every time they need this job accomplished. They can explain the differences in the techniques and why one method should take precedence over another based on the requested material, tool size and requirements and turnaround time.
All of these factors put together are going to give you the right balance of budget and quality. They may be able to offer reaction injection moulding, CNC machining, 3D printing and a variety of options but what counts is what will work for your specific project at that time and will save you money in the long run. Having it done right the first time is always the best option.
