Vinyl dip moulding production

The production process starts once the design phase and the first prototype product have been successfully completed. Below, we explain the production process of vinyl dip-coating and dip-moulding.

Vinyl dip moulding

In vinyl dip moulding, the liquid PVC goes into large, heated containers. Aluminium moulds are preheated and then immersed in the liquid mass. The PVC then adheres to the dip mould and leaves a thin layer on the mould. The heat of the mould combined with the dipping time determines the thickness of the plastisol. The mould is then reheated where the plastisol melts and then cures. After this, the formed vinyl can be removed from the mould. This is done using compressed air. The vinyl caps and plugs are elastic, so even complex shapes can be easily removed from the dipping moulds.

Vinyl dip coating

The difference with dip moulding is that with vinyl dip coating, the supplied product is dipped whole in the plastisol, which is then cured by heat. Dip coating is mainly used to protect materials such as wire grids and racks but also, for example, the handles of tools.

Costs of dip moulding products

In practice, the cost for initial production usually turns out to be significantly lower than the cost of designing a prototype. This is because when the prototype is made, the settings of the dip moulding process are specified, including dipping speed, dipping time and temperature of the furnaces. When ordering large numbers of products, the ideal ratio between the number of moulds and the quantities of products, we examine the ideal ratio between the number of moulds and the number of dips required to produce as efficiently as possible.

Advantages dip moulding process

With vinyl dip moulding and vinyl dip coating, you do not have to deal with seams or unevenness. Also, dip moulding is a very precise process because the plastisol follows the details of the mould exactly. In addition, the possibilities are endless when it comes to colours, textures and thicknesses. The finish of vinyl products can range from glossy to matt. It is amazing what shapes can all be made by vinyl dipping.
