Before we are able to cast a product we need to turn the 3D model or the hand mode part into a silicone mold. A suitable silicone would be chosen depending on the part to be made. We normally use a silicone with a Shore hardness of 25 (this means that the silicone flows nicely) for run of the mill molds. A food-safe silicone could be used to make chocolate molds. Once the "Master Model" is ready we analize the part to determine the best way to create the mold. There are numerous issues to consider, is it a flat part, does the part have undercuts (esentially this means that the lower part of the model is wider that the upper part making it difficult to extract the casting). Another thing that needs to be determined is where the split-line will be (esentially the line at which the upper mould meets the lower mold. This line could be uneven due to the shape of the model. One decisions have been made as to how the mold will be laid up the process starts.

We make many, many molds for our train products. We spend a lot of time on our own molds to ensure that we produce only the highest quality products. The same goes for your parts. Why would we do a lousy job on your product if we take so much pride in our own products.
