Using Plastic Molds For Candlestick Making

Using plastic molds for candlestick making has several positive aspects. In this article, I explain the benefits and disadvantages of the different types of plastic molds.

There are three materials that plastic molds are produced from; Latex, Polyurethane and silicon. Latex was the original plastic mold but with advances in the polymer bonded industry, latex molds are quickly becoming vanished.

Polyurethane Molds: These are perfect for candlestick making. They are flexible but they don't stretch well. Polyurethane molds when expanded do not always retain their original shape. Because they don't stretch as well, some polyurethane molds come with a split down the medial side that enables them to be demolded easier. This does leave a noticeable parting line. They normally are cheaper than silicon plastic molds. They do need release agents and sometimes have a strong smell that can pass to your candlestick. Many large pillar and taper candles are produced from polyurethane. When your candlestick hobby turns into a flourishing business, polyurethane molds are a definite choice for mass manufacturing of unique formed candles.

Storing and cleaning of polyurethane molds: Polyurethane molds should not be stacked or stored in a distorted position. If they are stored in a distorted position they will stay this way and might become useless. Trouble and soap will be sufficient to clean these molds. Make sure that the water has either dried or evaporated before using the molds again.

Water and feel do not mix.

Silicone Molds: Silicon molds are the most high-ticket. They have superior qualities when compared to their counterparts. They don't require a release agent. They come in many sizes, shapes and flexibilities. They will stretch to varying degrees and retain their original shapes. They normally are one piece and reveal no parting line.

Storing and cleaning of silicon molds: Silicon molds should not be stacked or stored in a distorted position. If they are stored in a distorted position they will stay this way and might become useless.

Warm water and soap will be sufficient to clean these molds. Make sure that the water has either dried or evaporated before using the molds again. Water and feel do not mix.
