Like CNC machining and 3D printing, silicone molding is an increasingly common production method, which can quickly create urethane casting parts for the production of small batches of functional parts. Silicone molding cost depends on various parameters, including the intricacy of your product, the quantity you need, and plenty of other variables.
How to make silicone molding, their prices, and what you can do to save money on silicone molding are all covered in this article. Make sure you read the article for some excellent cost-saving recommendations.
What Do You Mean by Silicone Molding?
A mold is a kind of container with a hollow space inside it. Liquids may usually be poured or pushed into containers, where they will solidify once they reach the proper temperature. Tool steel or aluminum are only two examples of materials that may be used to make the mold. Flexible protective casings, valves, and contact lenses can also be produced from silicones—a category of polymers made up of siloxane.
Compared to metal molds, silicone molds are less robust but easier to create and are more flexible. As a result of this flexibility and the fact that few things stick to silicone, it is pretty simple to remove molded pieces from the molds.
How to Make Silicone Molding?
The flexibility and low cost of silicone mold make them a great alternative to metals. You shouldn’t worry about how to make silicone molding and whether it’s simple or not. Silicone fabrication is much simpler than you may assume. Moreover, you will require the following components:
- Master Pattern
- Container
- Clay
- Liquid Silicone
- Casting equipment
- Mold Release
How Much Can a Silicone Mold Cost?
In silicone molding, the cost of the mold, or tooling cost, is often the critical cost driver. The production volume, the complexity of the design, the material used for mold, and how they are made are the deciding factors for the cost. Low-volume 3D printed molds may cost as little as $100, while complicated molds for high-volume production might cost as much as $10,000 to design and produce.
Low variable prices due to low-cost ingredients, quick cycle times, and reduced labor requirements due to automation and economies of scale make silicone molding cost-effective. In other words, by spreading out manufacturing expenses across a larger number of units, the process becomes more efficient, lowering both its per-unit cost and overall unit cost.
The Factors that Impact the Silicon Molding Cost
Silicone molding tooling prices are pretty high and rely on a wide range of factors, including the intricacy of the design. To guarantee that the mold cools down rapidly, it is equipped with features such as the surface geometries required for a component, an injection runner system, and cooling channels. The factors that impact the cost of silicone molding are:
-
Shape Complexity
Sometimes you need a mold with complicated shaped to do the job. Molds generally have two sides, A and B. Side A, often known as the cosmetic side, is typically the side that is viewed by the user and is hence more critical. It is intended that Side A would be free of imperfections and appealing to the eye. The supporting structures for the portion are buried on Side B. It is typical for the finish on Side B to be rougher than on Side A, with ribs and bosses. Molds with more complex Side A and Side B patterns often cost more. It may be necessary to add additional costs to the mold for complex designs that incorporate undercuttings, such as a sliding side-action and core.
-
Mold Cavity Sizes
Mold cavity size is what we mean by part volume. The longer the press time, the more cavities or cavity volume the mold needs. The manufacturing process is slowed down by longer press times, which results in higher costs.
-
Mold Quality and Production
A mold’s quality and production technique are determined by the number of products to be molded and the kind of material used. It’s possible to get away with 3D-printed silicone molds for low-volume projects. Still, larger production volumes would need high-quality molds or possibly numerous molds to avoid wear and tear impacting the quality of the finished products. High-volume molds are more expensive to produce, but a reduced per-part cost offsets this since the additional cost is spread across many parts.
Tips to Save Money on Silicone Molding
You can utilize the following tips to save yourself some money while dealing with silicone molding:
- Avoid Unnecessary Aesthetics: To save money, specific aesthetics should be avoided favoring a more functional design. Bead blasting, high mold polishing, etc., may not be necessary for all circumstances. Don’t use them if they are not required to save money. It is possible to save money if you need to polish a portion of the mold or a small region of it rather than polishing the complete mold.
- Re-use the Previous Mold: Instead of acquiring a new mold, you can have an existing mold repaired or re-made to meet your new requirements. If done correctly, this method can save you money, consequently decreasing the cost of silicone molding tooling. Replace the old design according to your requirements. And you’ll be able to satisfy your current requirement without having to make a whole new mold.
- Go for the Right Size: Picking the right mold size might save you time and money in the long run. Mold sizing is an essential consideration if you want to keep demand for your components stable and use bridge tooling to save money. Silicone molding expenses can be reduced in yet another manner by using this technique.
Conclusion
Since silicone molding is amongst the most common production methods in the industry, people wonder how much silicone molding costs and how they can save money on it. This article has covered the pricing of silicone molding and tips to reduce its cost to make it easy for them.
