The Process of Rubber Injection Molding

Information may not be reliable

Several ways of carving up effective rubber molding products exist, making them ideal candidates for high-volume applications, but rubber injection molding is arguably the most reliable process. Many rubber molded parts manufacturers utilize this process to create standard and custom parts and are excellent for more complex parts. These manufacturers will use different materials, allowing for the completion of rubber-to-metal bonding for equipment safety as well as vibration control.

This is a great way to create reliable rubber molded products and can be done with a few simple steps.

How Does the Process Work?

Firstly, the injection molding machine’s screw is fed with rubber that isn’t cured. Then the injector pulls in the rubber. Liquidation of the rubber subsequently takes place at the highest possible temperature.

From there, the liquid polymer is injected into the injection mold cavity using a runner and a gate. The rubber material is then vulcanized and cured at high pressure and temperatures before the rubber part is removed from the mold cavity.

The machine that develops these injected rubber molded products is a huge one. However, rubber molded parts manufacturers will tell you that the product can be made at a high speed with strong precision and efficiency, allowing for mass production of custom molded rubber parts at your convenience.

What Materials Are Used?

Rubber molded parts manufacturers love rubber injection molding because it can be done while using an array of parts. Several polymers can be used during the process, including:

• Silicone Polymers
• Nitrile rubber Polymers
• Fluorosilicone Polymers
• Liquid Silicone Rubber Polymers
• Natural Rubber Polymers

These rubber/polymer parts are used for improved vibration control or for machine protection. They become operable after being bonded to a mount or the equipment itself. Several metals are used during the bonding process, including aluminum, copper, steel, beryllium, and brass. The materials are chosen depending on the intended use or whether it’s a strong or durable part.

What Are the Advantages of Rubber Injection Molding?

The benefits that rubber injection molding provides are plentiful. It can be advantageous compared to other forms of molding like compression molding and transfer molding.

This process allows for the creation of more layered designs while also leading to quick cycle times and eliminates preforms. On top of that, there’s less waste and rubber flash left over. Rubber injection molding is perfect whenever a high volume of products needs to be made. Plus, it’s a very precise method. For companies looking to produce high levels of molded rubber products in a short time, rubber injection molding is the wisest choice.
