3 Most Common Methods To Make Precise Rubber Molded Parts
Rubber Molds have become one of the most sought-after solutions in industries. These molds are used in almost every industry and offer a multitude of advantages to the industry owner. You can expect these molds to withstand extreme temperature, and electric shock, and even stands the test of time. All of these benefits make them a clear winner in the market. If you are looking for a tough solution that will make the production process easier and more efficient, silicone will be the best option for you. However, before you take the leap and bring them to your industry here are some important things you must be aware of.
What are Silicone Rubber Molds?
Silicone rubber molds are an elastomer that is made up of silicone along with carbon, hydrogen, and oxygen atoms. They are non-reactive, stable, and can withstand extreme temperatures making them ideal for many industries. Due to their excellent chemical and physical properties, they are used as prototypes for many products and are known to provide accurate results. There are different varieties of silicone molds available in the market and you can choose one according to your needs.
Why use Silicone Rubber Molds?
Silicone molds in the liquid form can take any shape easily even in the most extreme temperatures. Once the silicone rubber is out of the mold it doesn't shrink and hold its shape for a very long time. They can also be made in a variety of colors making them a superior choice in many industries including food and beverages. Many liquid rubber mold-making companies use silicon and other strong material to make their molds.
Here are some of the notable advantages that make silicon rubber molds a preferred choice in the market.
- It can be molded in different shapes
- It resists electrical shock.
- They are known for their durability and stability.
- Inexpensive and fast manufacturing.
- They are known to retain their quality even in large productions.
How is Liquid Rubber Mold Making Carried Out?
Silicone rubber custom moulding is carried out using various processes, one of which is listed below with detailed steps and explanations.
Creating Master Pattern
The first step in the process is duplication, it is the process of creating the master pattern. This pattern is created by using modern rapid technologies. It is important to look for a rubber moulding company that uses high-tech modern technologies to produce 3D silicon molds like Rubber Silicone Molds. They are known for their excellent quality and make custom-made molds according to the requirement of their customers.
Designing the Rubber Mold
After duplication, the next step is gating and venting. The gates and vents allow the casting material to flow smoothly in the rubber mold. The shape and volume of the master pattern decide the location of the gates. Greater the mass of the master pattern, the bigger the gate space.
While designing the rubber mold, it is crucial to choose the right silicone rubber according to your requirements, different custom molded rubber parts require a different type of silicone rubber. While selecting the appropriate silicone rubber for your mold, you should look for molds that can easily resist inhibition.
Inhibition occurs due to contamination present in the silicone or on the master that has to be molded. A patch test is suggested prior to the molding process to remove any contamination present in the material.
Making the Rubber Mold
After the creation of the master pattern, a silicone mold can be easily molded. There are mainly two types of arrangements that are used in the silicone rubber molding process.
The first one is single-stage molding, in this technique the master pattern is gently let down in the mold box. After this, the liquid silicone rubber is poured inside the box until it is filled. Once it is cured, the mold is hacked down into two pieces.
The other method used for molding is two-part molding. This method is considered more labor intensive than the other one but is proven to provide accurate results due to better mold stability. In a two-part mold, a parting line is created with the help of molding clay, silicone is then poured into half of the mold. After pouring, the mold is inverted and the parting line created is removed along with the silicone. After this, the frame is restored and the other part of the mold is filled and cured.
Applications of Custom Molded Rubber Parts
Because of its many advantages, rubber custom-molded products are used in a wide range of industries, such as:
- Medical industry
- Food and beverage industry
- Defense industry
- Aerospace industries
- Construction and restoration industries
