Dip moulding is a shaping process in which the shape of the product is created by dipping a mould into a liquid material. The advantage of dip moulding is that the product has no seams. Moreover, the moulds are easy to create, making dip moulding an affordable manufacturing process. Also, the time required to get from design to final product is many times shorter than, for example, injection moulding.
Caplugs has built up considerable expertise in designing and manufacturing dip moulds. We describe for you the process from design to vinyl prototype.
Before our engineers start working on a design for a vinyl prototype, we first need to know what needs to be protected. Then we can immediately determine whether the plastisol dipping method is the right method for this application. Here are some important questions:
- What should the shore hardness be?
- Should it be resistant to high temperatures?
- What should the wall thickness of the vinyl be?
Once we have determined all the characteristics and dimensions, we start working on the design. STEP-file PDF formats often contain important information about the product to be protected. This is crucial for determining customisation requirements, such as size and depth. Based on this document, the programme automatically calculates the diameter of the cap and the costs become clear. In doing so, we indicate whether we can blow-dip the product or whether some other processing needs to be done, such as cutting a hole.
