Some design consultants receive compliments from mold shops about the parts they design and how the products seldom require any changes.

This, in great part, is the result of the design consultant knowing precisely what its designers can accomplish.

There is a range of skills and practices amongst design consultants and it’s important to understand these capabilities. If a design consultant is experienced, your life will be easier and the project may even require less time and effort. If they are not, you can help them understand what is expected and assure the end result meets your satisfaction.
You might want to develop a checklist of questions to ensure designers are correcting the design early on. Some design firms like working with moldmakers and molders that will take unfinished designs and solve all the molding problems. Others prefer moldmakers and molders that build exactly what they design. You just need to understand whom you’re dealing with and use them accordingly.
