How do we do it? Specialized! Dip moulding process suitable for flexible vinyl parts

Dip moulding is a low-cost method of producing a durable, high quality end product. The vinyl material used is well suited to the production of both large and small complex shapes, in all kinds of colours and material hardnesses.

From an aesthetical point of view, dip moulded products can offer added value to products for industry and consumers. Small quantities up to thousands of products can be easily manufactured.

Dip moulding process step by step.

1. The mould

To make a special dip moulded part, we first have to make a mould that will form the inside of the product. In the prototype stage the first tests will be done and, if needed, adjustments can be made. If the quality of the prototype is good, a number of production moulds will be made, depending on the size of the series. These aluminium moulds will be turned, shaped or made from an aluminium casting.

2. Heating the mould in the oven

The mould will be preheated in an oven.

3. The heated mould will be dipped in liquid plastisol

The mould is attached to a special frame and is dipped in a bath of liquid plastisol. A combination of mould heat and dipping time will determine wall thickness.

4. Curing of the dipped mould in the oven

To make a special dip moulded part, we first have to make a mould that will form the inside of the product. In the prototype stage the first tests will be done and, if needed, adjustments can be made. If the quality of the prototype is good, a number of production moulds will be made, depending on the size of the series. These aluminium moulds will be turned, shaped or made from an aluminium casting.

5. Cooling of the dipped mould in water

The mould is dipped for a short time in water so that the applied layer can cool down and cure.

6. The product will be stripped from the mould

The end product will be removed from the mould with compressed air.

7. Complete end product

If needed, the product can be sliced, punched or printed.
