Your Silicone Soap Bar Mold

Silicone Offers The Highest Detail

Our silicone cavity molds work great to control your product. First, you get highly accurate and consistent soap bars. This is great for reproducing your logo and artwork accurately and every soap bar is the exact weight each time thus controlling costs. Plus, there is terrific value in a branded product.

​Making A Single Mold To Replicate Your Perfect Soap Bars

To ensure constructing a quality working silicone mold, we cast one and only one perfect model of the soap bar.  ​

​A 12-Cavity Production Mold Requires 12 Perfect Models

Using this single silicone mold, we replicate twelve model soap bars, or twenty-four smaller sampler bars to ensure the quality of each soap bar is consistent throughout the replicating process.

​Making The Block Ensures Future Growth and Savings

The construction of the block is unique to Masterline Molds. The importance of making the block ensures the quality of your product as any number of silicone production molds can be cast using the block. Re-ordering is easy, and the only cost is the cost of the silicone mold.

​Casting Silicone Rubber To Make Your Production Molds . . .

We use medium strength, two components, tin catalyzed, room temperature cured 20 A shore strength silicone rubber. You need not use expensive food-safe silicone as no food products are produced.  You do not need to use expensive platinum base silicone, as we are not making resin products. The oval and circular bars are also arranged in rows and columns rather than an ‘off-set.’  Our customers have told us de-molding of these bars offers convenience and easier release.

Construction Of The Silicone Mold

​Each production mold is sectioned by a full ¼ inch silicone border around and between each soap bar as well as full ¼ inch side borders. The thicker bottom stabilizes the mold to give a highly accurate detailed reproduction of your soap bar. The rectangle and square soaps are the most cost-efficient molds to produce. The oval and circular soaps require a little more material as the silicone fills in and around the missing corners of the soap bars. However, the extra cost of the silicone is small as the oval and circular bars are the best and popular selling bars.

Ganging The Individual Mold Mats

​Each 12-cavity mold measures about thirteen by fourteen inches. Sometimes, we are asked to make a specific size of mold to accommodate a client's tray size or platform. No problem. Working with a series or multiple 12-cavity molds is much easier than working with one super large silicone mold. Ask yourself how you lift and manage a 50- to 60-pound silicone mold and how do you store it. You can still cast your 100 or 200 soap batch by ganging the mats side by side, end to end.
