Working with a silicone mold is so easy and convenient. There is no 'ON' or 'OFF' switch, there are no aggravating beeping noises when they are finished. They are always ready to work. THEY DON'T COMPLAIN -- not even about the weather, and they continual do their job very well. Our silicone molds do not have an expiry date, no best before or don't use after date, meaning no need to replace them any time soon. And from time to time, all they ask, is a little TLC.
Silicone molds save time and money
A popular choice with soap makers is the use of silicone molds. Why? Silicone molds are easy to use, easy to clean, no need for spray releases, no need to continually line as in loaf pan mold, no need to use spray releases as in the cases of plastic acrylic soap bar molds. Every cast produces professional looking soap bars in great detail of your brand name. There is no need to hand slice a slab of soap -- the weight and size of your soap bars are always consistent.
Our silicone molds are flexible, soft, yet durable
Our molds can be twisted, stretched, pulled, or dropped and they still will not lose their shape -- unlike plastic sheet molds which require constant replacing due to tearing, shredding, warping, and so on. Our silicone rubber has a memory. And this memory allows your molds to return to its original shape, each and every time. Our custom silicone molds will soon become your 'anchor go-to molds' for all your soap recipes.
Do silicone molds take on the scents or colors
Our silicone molds do not take on any scents, oils, or perfume you may use in your own exclusive soap formula. You can cast all your different soap formulas using the same mold. For example, you may use the same silicone mold to make soap bars, wax products, bath flizzies, hard lotion bars, and even pumice bars. In some of these cases, your formula would start as a liquid slurry and then solidify to a harden state for de-molding.
Can silicone molds be used for hot or cold recipes.
Our molds can withstand temperatures up to 350° F. and for rapid cooling, our molds may be placed in cooling units. Our you can place them in a freezer for a short time, of course.
Complete control over the exact weight and dimensions
Our silicone molds can be created as 6-, 8-, or 12-cavity molds, although we recommend creating a 12-cavity mold. The number of cavities in the mold will produce that number of soap bars in a single cast. Your mold will give you complete control over the exact weight and dimensions of your soap bar. There is no need to be concern about the correct weight and size as with hand-cut soap bars. And each time you cast, your cavity molds give you a uniform consistency of your name or logo.
What we don't do
Masterline does not make hot vacuum-formed sheet plastic molds. After awhile, the sheet molds will start being problems for soap makers. For this reason, Masterline decided from very early beginnings to produce a high-quality silicone soap mold -- a mold which will last for years.
Masterline does not use polyurethane RTV rubber to make your production molds. We learned quite early in our beginning, that the finished soap bars would adhere tenaciously to the polyurethane rubber. No amount of cleaning or use of mold releases could prevent the finished soap bars from sticking. The mold soon builds up a scale-like residue which is hard to remove. The silicone rubber gives a clean release thus eliminating any soap-scale build up.
The construction of your silicone rubber molds
Our team at Masterline takes great pride in constructing your silicone molds. We know your molds are going to last a long time, so we better get it right the first time. Your molds are built on a square or rectangle platforms which gives each soap bar cavity great stability. Your silicone molds are cast a thicker bottom (more silicone) to reduce 'snaking'. Your molds are un-like any press molded silicone cup cake mold offered in the box stores. These molds could 'snake' as there is no support or stability in this type of mold. As there is little or no support, there may be miss-shaped soap bars as finished products. Your molds are not made of hardware store silicone that comes in a tube.
Free Trade Agreements
We use an industrial strength grade of silicone which is 'Made in North America' to meet current Free Trade Agreements.
